Strange Behavior for Delay?
|
<p>In the code below the page will fade in, and then it will fade in the list items on the left, and then its suppose to fade in each thumbnail on the right. But because of me using .delay() it ends up skipping the loading of some or all of the thumbnails. Is there something else other than .delay() I can use to halt the execution of the thumbs fading in before they should begin to?</p>
<pre><code>//Showcase
$('#showcase').animate({'opacity' : 0}, 0);
fadeInDivs(['#showcase']);
function fadeInDivs(els) {
e = els.pop();
$(e). delay(750).animate({'opacity' : 1}, 1000, function(){
if (els.length) fadeInDivs(els);
});
};
$('#showcase').queue(function(){
//fade in each filter
$('#filters li').each(function(i, item) {
setTimeout(function() { $(item).animate({'opacity' : 1}, 1000); }, 50 * i);
});
//fade in each thumbnail
$('.thumb').delay(1000).each(function(i, item) {
setTimeout(function() { $(item).animate({'opacity' : 1}, 1000); }, 500 * i);
});
});
</code></pre>

Something with callback
|
<p>Already for 15 minutes I can not understand</p>
<pre><code>if(send == true){
$.getScript('index.php?get_names_from_ajax=true', function(data){
$('#firstnames').remove();
$('#lastnames').remove();
$('#content').prepand('<div class="block" id="firstnames">'+firstnames+'</div>');
$('#firstnames').after('<div class="block" id="lastnames">'+lastnames+'</div>');
send = false;
});
alert(send);
}
</code></pre>
<p>getScript works fine, but callback gives no results. </p>
<p><strong>EDIT</strong></p>
<p>As i said, all callback is off, nothing removes or adds, just no moving, like there is no callback. </p>

What's the purpose of jQuery.fn
|
<blockquote>
<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/4083351/what-does-jquery-fn-mean">What does jQuery.fn mean?</a> </p>
</blockquote>
<p>Part of the jQuery source code states:</p>
<pre><code>jQuery.fn = jQuery.prototype = {
</code></pre>
<p>Given this, wouldn't </p>
<pre><code>$.fn.adamPlugin = function(options) {
return this.each(function() { });
};
</code></pre>
<p>Be identical to</p>
<pre><code>$.prototype.adamPlugin = function(options) {
return this.each(function() { });
};
</code></pre>
<p>If so, what's the point of <code>$.fn</code>? Adding things to a prototype is fairly common in JavaScript, so I can't quite understand why the jQuery folks would try to abstract this away. </p>

Is it good to write javascript functions inside functions and not use 'new' on the main function?
|
<p>I now know this works:</p>
<pre><code>function outerfunction(arg1, arg2, arg3) {
var others;
//Some code
innerFunction();
function innerFunction() {
//do some stuff
//I have access to the args and vars of the outerFunction also I can limit the scope of vars in the innerFunction..!
}
//Also
$.ajax({
success : secondInnerFunction;
});
function secondInnerFunction() {
// Has all the same benefits!
}
}
outerFunction();
</code></pre>
<p>So, I am not doing a 'new' on the outerFunction, but I am using it as an object! How correct is this, semantically?</p>

Issues exporting datagridview to excel
|
<p>I'm trying to do an export of a datagrid to excel. For some reason, known working methods aren't working. The export is done from a user control. My page (default.aspx) uses a master page and the page has a user control that actually has the datagrid I'm trying to export. </p>
<p>Here's my code on the ascx:</p>
<pre><code>Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
_gvwResults.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
</code></pre>
<p>On my default.aspx (page the holds the ascx) is this code:</p>
<pre><code>public override void VerifyRenderingInServerForm(Control control)
{
/* Confirms that an HtmlForm control is rendered for the specified ASP.NET
server control at run time. - required to export file */
}
</code></pre>
<p>Here's the error I receive:
Sys.Webforms.pagerequestmanagerparsererrorexception. The message received from the server could ot be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, httpmodules or server trace is enabled.</p>
<p>Any ideas? This code should work but it's almost as if the response object is not being cleared. Ideas?</p>

Suspend Default Event in jQuery
|
<p>I am trying to delay the default event or events in a jQuery script. The context is that I want to display a message to users when they perform certain actions (click primarily) for a few seconds before the default action fires.</p>
<p>Pseudo-code:
- User clicks link/button/element
- User gets a popup message stating 'You are leaving site'
- Message remains on screen for X milliseconds
- Default action (can be other than href link too) fires</p>
<p>So far, my attempts look like this:</p>
<pre><code>$(document).ready(function() {
var orgE = $("a").click();
$("a").click(function(event) {
var orgEvent = event;
event.preventDefault();
// Do stuff
doStuff(this);
setTimeout(function() {
// Hide message
hideMessage();
$(this).trigger(orgEvent);
}, 1000);
});
});
</code></pre>
<p>Of course, this doesn't work as expected, but may show what I'm trying to do.</p>
<p><strong>I am unable to use plugins as ths is a hosted environment with no online access.</strong></p>
<p>Any ideas?</p>

Best way to display dynamic list of objects in asp.net
|
<p>I'm building an asp.net page that is designed to display links for a user that views the page.</p>
<p>The links are to reports, which have security on them, and that will be delegated as part of this site.</p>
<p>An SQL table will hold a record for each report that exists, with its corresponding security requirements.. I haven't quite figured this part of the system out yet, but that's not an issue.</p>
<p>When a user visits the page, I only want display the records that particular user has access to. Which leads me to my question.. What is the best way to hide/show links, based on a user login (fuzzy security her for the moment), which can handle a new report being added dynamically.</p>
<p>By dynamically I mean if my site has a section to create a new report link, which everyone has access to, then the front page automatically displays this new link when a user visits the page.</p>
<p>Simple user case:
UserA has full rights, so they log on and see 4 links on the page.
UserB has limited rights, so they log on and see 1 link on the page.
UserX creates a new report which everyone can see.
UserB logs back on and now can see 2 links.</p>
<p>My very first idea was labels hiding and showing, but this is dumb, but thats the general concept of what i'm after.. </p>
<p>Hopefully this makes sense, and I look forward to your help.</p>
<p>Thanks!</p>

Centering a div within another div while scrolling
|
<p>I am trying to center the navigation within the main content div and have it stuck there while scrolling. The problem that I just can't wrap my head around is that it needs to be parallaxy because of the header and the footer. I have a staging environment <a href="http://stage.golishlaw.com/portfolio/" rel="nofollow">http://stage.golishlaw.com/portfolio/</a> </p>
<p>I cannot write down everything that I have tried but some of the most recent stuff is:</p>
<pre><code>var _mainHeight = (($(window).height()/2) - ($("#portfolio_nav").height()/2)) + (($("#main").offset().top - $(window).scrollTop()))
$("#portfolio_nav").css({
top: _mainHeight
});</code></pre>
<p>This one worked well on some monitor sizes but not others.</p>
<pre><code>var mainScrollTop = (($(window).scrollTop() - $("#main").offset().top));
mainScrollTop = mainScrollTop > 0 ? 0 : mainScrollTop;
var _mainHeight = ((($(window).height() )/2 - $("#portfolio_nav").height()/2) + $("#main").offset().top) + mainScrollTop
$("#portfolio_nav").css({
top: _mainHeight
});</code></pre>
<p>This one work pretty well to but the nav got stuck at a certain spot (I know why I just can't figure how to get it stuck in the center of the screen)</p>
<p>I've just really been pulling my hair out on this one and I've tried everything that I could think of.</p>

PHP Problem : filesize() return 0 with file containing few data?

<p>I use PHP to call a Java command then forward its result into a file called result.txt. For ex, the file contains this:
"Result is : 5.0"
but the function filesize() returns 0 and when I check by 'ls -l' command it's also 0. Because I decide to print the result to the screen when file size != 0 so nothing is printed. How can I get the size in bit ? or another solution available?</p>

Converting PHP code in Java

<p>I'm a PHP programmer starting my adventures in Java and I was trying to create a function in an auction program to award my suppliers (it's something really simple, that I am using just for doing some tests). </p>
<p>As I wasn't finding a way to do this, I decided to write a sketch of how I could possibly do that in PHP and ask you here how could I transform this PHP code into Java:</p>
<pre><code> $aux = null;
$val = null;
foreach (this->auction->getBids() as $bid) {
if ($aux == null) {
$aux = $bid->getValue();
} else {
if ($bid->getValue() > $aux) {
$aux = $bid;
}
}
}
</code></pre>
<p>just because u complained, I was starting doing something like this:</p>
<pre><code>public void award() {
for (int i = 0; i < this.auction.getBids().size(); i++) {
this.auction.getBids().get(i).getSupplier().getName();
this.auction.getBids().get(i).getProduct().getName();
this.auction.getBids().get(i).getBidTime();
this.auction.getBids().get(i).getValue();
}
</code></pre>

asp:CheckBoxField in GridView - VS 2008
|
<p>I have a gridview control bound to an object data source. in addition to the columns that i want to display i want to display this</p>
<pre><code> <Columns>
<asp:CheckBoxField DataField="Locked" Visible="true" AccessibleHeaderText="On Hold" ReadOnly="false"/>
</Columns>
</code></pre>
<p>Couple of questions here:
1. If I do the above said, my page loads and certain rows have their records marked as checked and certain rows do not, as per data. However, the user is unable to click on any records to undo their check marks. It appears that this is in a disabled state.</p>
<ol>
<li><p>It seems there is no onclick event with this checkboxfield. I want to update my records instantly when the user checks or unchecks each record. yes bad design here but my hands are tied</p></li>
<li><p>If i were to go with <code><asp:checkbox></code> within an <code><itemtemplate></code> how do i bind that to my locked column within the object datasource or do i have to do that by overiding onne of the methods of the gridview control?</p></li>

How do I clear the selection in an Android Submenu?
|
<p>I have a menu in my Android application and this menu has a <code>SubMenu</code>. The items are exclusively selectable.</p>
<p>How can I remove a selection made by the user (such that the submenu looks like it was at the beginning, with no item selected?</p>
<p>I was looking for a method that would do this, in a similar way as the <code>SubMenu</code>'s <code>setGroupEnabled</code> method, so I tried it by looping over the items of the submenu and call <code>setChecked(false)</code> on them. However, as it seems, deselecting an item in an exclusive list does not remove the selection, but shifts it to the next item. So after the loop, there was still any item selected.</p>
<p>What is the correct way of removing the selection (so that the user can select a new item)?
I appreciate your help.</p>

How to make so that the function run only one time?
|
<p>Script number one performed for each of a given set of elements DOM, append to the first element of the DOM script number two. </p>
<p><strong>Script number one:</strong></p>
<pre><code>function ptmedia(){
$('.ptmcss').eq(0).html('<div class="ptmcss"></div>')
.append('<div class="append"><script type="text/javascript" src="script2.js"></script></div>');
$('.spbin').each(function(){
if($(this).children().attr('class').indexOf('ptmd')!==-1){
$(this).addClass('ptmedia');ptmedia();}
</code></pre>
<p>Script number two does cross domain query, the fulfillment of which performs the specified function <strong>(z)</strong>.
<strong>Script number two</strong>:</p>
<pre><code>$.getJSON('http://example.com?callback=?',function(z){alert(z.query+'Some text');}
</code></pre>
<p>Due to the fact that the script is the number one multiple times, the function <strong>(z)</strong> holds an equal number of times. How to make so that the function <strong>(z)</strong> run only one time?

// update the result array
var result = JSON.parse(localStorage.getItem("result"));
if(result == null)
result = [];
result.push({id: id, icon: text});
// save the new result array
localStorage.setItem("result", JSON.stringify(result));
// append the new li
$("#bxs").append($("<li></li>").attr("id", "item-"+id).html(text));
});
// on init fill the ul

If there's already free plugin, then I need plugin, which is free for commercial use (allowed to be sold in marketplaces with ready blog/portfolio templates).</p>

Read server-side JavaScript from PHP
|
<p>I have a JS library file of variables (caption strings) used by <em>server-side</em> JavaScript. Can I read/interpret that from PHP?</p>
<p>The path to the data isn't the issue, but whether PHP can read/use the JS variables. Currently I've the same variable stored in both a JS file and PHP include with obvious scope for changes getting out of synch. I've tried reading the PHP from the <em>server-side</em> JS without joy but was wondering if - with suitable parsing - if PHP could extract/use the JS variables.</p>
<p>I repeat <em>all</em> data involved is <em>server-side</em> on the same server. Sorry if I've missed this being answered before but PHP/JS questions are (even if mis-titled) seemingly all about passing data between client and server side processes - which isn't my scenario.</p>
<p>Later - clarification:</p>
<p>The s/s JavaScript is part of a web interface to an image database where I can't alter the API. It doesn't support creating emails (for file requests) thus I am having to do that via PHP. Work scope/budget precludes re-writing a new d/b interface, rather we 'just' ned to be able to send an email. IOW, I realise you wouldn't choose to be trying to do this if starting from scratch! Also, I don't think I can do s/side AJAX to fetch variables or do PHP smtp mail as the JS environment seemingly isn't designed for that degree of s/s processing pre HTML page delivery.</p>

How to show an absolutely positioned sibling div on hover using jQuery?
|
<p>I have a grid of images with accompanying info in a sibling div that needs to show when the image is hovered over, then disappear when the cursor is off the image. I've looked at several similar questions here but none really have worked for what I need exactly.</p>
<p>It's for a site I've inherited that uses a different JS library that I'm switching to jQuery but I'm having a tough time figuring this out as I'm still learning jQuery.</p>
<p>I've set up the HTML & CSS here: <a href="http://jsfiddle.net/EQ2fG/" rel="nofollow">http://jsfiddle.net/EQ2fG/</a></p>
<p>There's a screenshot of what I need here: <a href="http://cl.ly/JZkK" rel="nofollow">http://cl.ly/JZkK</a></p>
<p>So on hover, the sibling div (.property_info) needs to display to the right of the image div (.property), but the ones for the last two in each row need to display to the left so it stays within the container/wrapper div. Keep in mind that the data will be dynamically generated.</p>
<p>I hope that makes sense. Any help would be really, really helpful.</p>
<p>Thank you!</p>

Set default value for jQuery slider and override when needed
|
<p><strong>Background:</strong> I currently have a <strong>working</strong> jQuery slider on my website inside my .js file</p>
<pre><code>$( "#slider-range-min" ).slider({
range: "min",
value: 100,
min: 1,
max: 100,
});
</code></pre>
<p>I need to be able to override the "Value" from 100 to some other value sometimes. So I tried this:</p>
<pre><code>$( "#slider-range-min" ).slider({
range: "min",
value: _Slider_Value,
min: 1,
max: 100,
});
</code></pre>
<p>and defined this on my html page</p>
<pre><code><script type="text/javascript">
var _Slider_Value = 50;
</script>
</code></pre>
<p>which also works! <strong>Except</strong> then on all the other pages I get a javascript error stating "_Slider_Value is not defined". I'd rather not have to copy & paste the value onto all my pages if I can avoid it... doesnt seem like a "good" way to do it?</p>
<p><strong>Question:</strong> is there a better way to do this - so I can have a default value for my slider, but occasionally override it when required?</p>
<p><strong>Edit:</strong> Another way of saying it: how do I make my slider default to "100" unless I tell it otherwise in my html page?</p>

jQuery-style function that can be accessed like an object
|
<p>I am creating an AJAX API for a web service and I want to be able to call jQuery-like accessors.
jQuery seems to be able to execute 'jQuery' as a function, but also use it to directly access the object that is the result of the function EG:</p>
<pre><code>jQuery();
jQuery.each({});
</code></pre>
<p>This is the trick that I can't seem to pull off:</p>
<pre><code>myAPI('foo'); //output: 'foo'
myAPI('foo').changeBar(); //output: 'foo' 1
myAPI.changeBar(); //Error: not a function
</code></pre>
<p>I have seen the answers to similar questions, which are helpful, but don't really answer my question.</p>
<p><a href="http://stackoverflow.com/questions/8734115/how-can-jquery-behave-like-an-object-and-a-function">#8734115</a> - Really interesting, but you can't access the methods that were set by f.prototype.</p>
<p><a href="http://stackoverflow.com/questions/2953314/javascript-function-like-objects-i-e-can-be-used-as-a-function-e-g-as">#2953314</a> - Uses Multiple operations to create object instead of a single function.</p>
<p>here is my code:</p>
<pre><code>(function(window) {
var h = function(foo) {
// The h object is actually just the init constructor 'enhanced'
return new h.fn.init(foo);
};
/**
* Methods defined at protoype.
*/
h.fn = h.prototype = {
constructor: h,
init: function(foo) {
console.log(foo);
return this;
},
splice : function () {},
length : 0,
bar : 0,
changeBar : function() {
this.bar++;
return this.bar;
}
};
h.fn.init.prototype = h.fn;
//Publish

Asp.Net "Instant" PM System

<p>I need to send "instant" messages (like forum PMs) between users with my asp.net application. As many others I use a webhotel to host my site. I have searched around for awhile and I can't find any solutions that would be a good fit with my system. I was thinking about writing a javascript that would call for each 30 seconds or so a .ashx handler to check the users message status (return true or false) if the correct credentials are supplied. However I dont know if this is a good solution, because of all the calls to the handler it might get picked up as spam or it might generate really bad performance? The thing is, I want to avoid the need to refresh the page just to see your latest messages.</p>

Live update textblock
|
<p>I am trying to figure out the best way to have a text field live update between two different users. I have done some googling and what I could find was the setInterval.</p>
<p>That works but is really straight forward and seems like the "wrong" way. I don't know why it seems like that but I feel like there would be a more efficient way than having a setInterval update every 100ms or so. </p>
<p>Is there a better way than using setInterval? What is the best to update between two users?
Thanks for the help or pointing me in the right direction.</p>

link click event not firing button click event on the first try (IE only). Works on second click.
|
<p>This is driving me mad. I've got a div on my page that opens up in colorbox. When the user clicks one of the links in the div, it fires an event to the code (below) which should in turn populate the hidden field and then click a server button to run some code behind.</p>
<p>Problem is, in IE(9) it won't click the server button on the first attempt (yes, it does go onto the client click event). Strangely it seems to work fine in Chrome and FF.</p>
<pre><code>$(document).on('click', '.link', function (e) {
e.preventDefault();
var thisID = $(this).attr('href').replace('#ca', '');
$("#hiddenField").val(thisID );
$("#button1").submit();
});
</code></pre>
<p>It might be worth mentioning that the links in the div that opens in colorbox is dynamically populated. But this should effect it as the click events on the links are working fine.</p>
<p>Any help would be appreciated.</p>

Why cant java be used over C++ for all programming purposes
|
<p>It is said that Java overcomes all disadvantages of C++</p>
<blockquote>
<p><strong>Disadvantages of C++:</strong></p>
<ul>
<li>Does not provide very strong type-checking. c++ code is easily
prone to errors related to data types,
their conversions, for example, while
passing arguments to functions.</li>
<li>Does not provide efficient means for garbage collection, as already
mentioned.</li>
<li>No built in support for threads.</li>
<li>Gets complex when u want to develop a graphics rich application in c++</li>
<li>portability of code on various platforms, etc</li>
</ul>
</blockquote>
<p>Then why is there a need for C++ language ?? Why cant we just use Java for all programming purposes??</p>

jquery: not selector problem?
|
<p>The following snippet applies a #breadcrumb hash to each link once it's clicked. That works fine.</p>
<pre><code>$('#main a').live('click',function() {
$(this).attr('href', $(this).attr('href') + "#breadcrumbs");
});
</code></pre>
<p>Now I want to make sure that happens just if a link does not already have a #hash in it. Otherwise what happens is I click a link and the outcome looks like this: <code>http://page.com/whatever#hash#breadcrumbs</code> I simply want to prevent that.</p>
<p>However the following code does not work. If I add the :not selector none of the links adds the #breadcrumb hash (with or without already existing #hash)</p>
<pre><code>$('#main a:not([href*="#"]').live('click',function() {
$(this).attr('href', $(this).attr('href') + "#breadcrumbs");
});
</code></pre>

Is it possible to loop through a textbox's contents? If not, what's the best strategy to read line-by-line?
|
<p>I am designing a crawler which will get certain content from a webpage (using either string manipulation or regex).</p>
<p>I'm able to get the contents of the webpage as a response stream (using the whole httpwebrequest thing), and then for testing/dev purposes, I write the stream content to a multi-line textbox in my ASP.NET webpage.</p>
<p>Is it possible for me to loop through the content of the textbox and then say "If textbox1.text.contains (or save the textbox text as a string variable), a certain string then increment a count". The problem with the textbox is the string loses formatting, so it's in one long line with no line breaking. Can that be changed?</p>
<p>I'd like to do this rather than write the content to a file because writing to a file means I would have to handle all sorts of external issues. Of course, if this is the only way, then so be it. If I do have to write to a file, then what's the best strategy to loop through each and every line (I'm a little overwhelmed and thus confused as there's many logical and language methods to use), looking for a condition? So if I want to look for the string "Hello", in the following text:</p>
<p>My name is xyz
I am xyz years of age
Hello blah blah blah
Bye</p>
<p>When I reach hello I want to increment an integer variable.</p>

Why is it possible to query jQuery('div') like an array?
|
<p>I got another question regarding jQuery's architecture. <code>$('div')</code> constructs a new <code>jQuery</code> object:</p>
<pre><code>$('div') instanceof jQuery; // true
</code></pre>
<p>I'd like to know why it is possible to query it like an array, allthough it isn't an array?</p>
<pre><code>$('div')[0]; // returns the first div in the document as a DOM node.
$.isArray($('div')); // false
</code></pre>
<p>I just love this syntax, it looks so clean! I also noticed this returns the DOM nodes as an array:</p>
<pre><code>console.log($('div'));
</code></pre>
<p>Can somebody explain me how to implement this behaviour to my own objects? </p>
<hr>
<p>My own approach was to make an array with some methods like this:</p>
<pre><code>var a = ['a', 'b', 'c'];
a.method = function(){ return 'test'; };
a; // ['a', 'b', 'c']
a[0]; // 'a'
a.method(); // 'test'
</code></pre>
<p>However this doesn't seem to be the way jQuery does it as this is actually an array:</p>
<pre><code>$.isArray(a); // true
</code></pre>
<p>I'd like to know how jQuery does this to learn and to see if it's a better solution than mine.</p>

Only show parts of image under a div using jquery

<p>I'm displaying a background picture with some semi-opaque div over it, so that it appears somewhat darker than it actually is. On top if it, I have a number of smaller, draggable divs. </p>
<p>I'd like the image to be completely visible, or revealed under these divs. These smaller divs should be like looking through windows to the below image.</p>
<p>One way to do it, is to set the background of each "window div" be a version of the larger image, and adjust the position to compensate for the div location. This works okay, but is kind of slow/jerky and very clunky.</p>

<p>I am trying to use javascript with server controls.</p>
<p>Aim<br>
To make my panel visible on mouseover event of text box(asp control)</p>
<p>Problem areas<br>
new to javascript and asp.net.<br>
getting javascript errors at run time<br>
went thru all possible solutions from different forums but not able to customize them accordingly.</p>
<p>The code runs on this ASP.NET Control</p>
<pre><code><asp:TextBox ID="TextBox1" runat="server"
ontextchanged="TextBox1_TextChanged"
onmouseover="enablepanel()"
Width="76px"
Text="--SELECT--">
</asp:TextBox>
</code></pre>
<p>Tried these scripts</p>
<pre><code>function enablepanel(sender, target) {
document.getElementById(target).removeAttribute("disabled");
}
function enablepanel() {
var id = $get("<%=Panel1.ClientID %>");
if (id != null) id.disabled = false;
$get("#<%= ButtonSave.ClientID%>").removeAttr("disabled");
var controls = document.getElementById("<%=Panel1.ClientID%>");
controls.disabled = false;
}
function enablepanel() {
document.getElementById(div1).disabled = "false";
}
</code></pre>
<p>Its not working.</p>
<p>Request<br>
if possible try to make it simple as we call functions in html when we use javascript otherwise just go with the solution.</p>

Page does not load when ScriptManager is not included on MasterPage, but does when ScriptManager is commented out
|
<p>I have been editing an existing ASP.NET website, and removing old code that is no longer necessary. </p>
<p>On the MasterPage there was a ScriptManager control that I removed. The page would then stop loading any content, and I would just get an empty body tag. However, if I leave the ScriptManager control in, but surround it with <!-- --> to comment it out, the page then loads. </p>
<p>If I uncomment the ScriptManager, I get an error in my Firebug console that reads "Sys.ArgumentException: Sys.ArgumentException: An element with id 'form1' could not be found.
Parameter name: elementOrElementId." The page still loads properly.</p>
<p>I checked to see if there was an UpdatePanel or anything else that I was aware of that might be using the ScriptManager and I can't find anything.</p>
<p>Can anyone tell me why this behavior is occurring?</p>

jQuery API-compatible micro framework (other than Zepto)?
|
<p>I would swear on my cat's grave that I just read about such a thing in the last couple weeks, but I can't for the life of me find it now. I am looking for a minimal framework covering basic DOM selecting (e.g., including Sizzle, so it works with IE6 -- so Zepto doesn't qualify), manipulation & event binding, but omitting just about everything else. </p>
<p>I need to add some very simple stuff to a VERY old web site and I want to use jQuery compatible syntax in case one day it needs more, but don't want to add 90K to the page size for this. I was hoping to spend approximately 30 minutes on this project, so I don't really want to cobble this together myself. Assuming I'm not imagining things, anyone know what I might be thinking of?</p>

How to access documentation in javascript
|
<p>Is it possible to access the documentation in the javascript at runtime as we do in python like </p>
<pre><code>object__doc__
</code></pre>
<p>I am just looking for an easy way to discover about inbuilt functions rather then googling for them all the time.
Also is there something equivalent to python's <code>dir(object)</code> , again I am looking for it because i don't know how to discover about what properties / functions an object exposes.</p>

Alternative Jquery mouse event
|
<p>Alright so the code below works fine if I click outside the #nav div. I was asking if it is possible to just move the mouse away from the #nav div to make it disappear. I don't want to 'click' to hide the div.</p>
<pre><code>$(document).mouseup(function (e)
{
var container = $("#nav");
if (container.has(e.target).length === 0)
{
container.hide();
}
});
</code></pre>
<p>Any help will be appreciated :)</p>

javascript and asp.net
|
<p>I am going to be doing a lot more front end work on one of our asp.net projects and I suspect there will be a lot more JavaScript involved. I have seen and used a lot of tutorials/info on the fundamentals of the JavaScript language but could someone point me towards some resources on JavaScript specifically for using it with asp.net? If specific tutorials/pages don't really exist then maybe some of the methods,tools,libraries etc. you would use and are worth reading about?</p>

Javascript, local copying of a variable's value... struggling to achieve it
|
<p>I have what i thought was a simple javascript / jquery function (fade out of one div, fade into another... loop until it reaches a maximum and then start back from the begining. The problem i have though is that to fadein the next div i need to increment the global counter. Doing this increments double increments it because i'm assuming the local variable i've created maintains the same reference to the global variable. </p>
<p>The code sample below should explain a little easier. Can anyone spot what i'm doing wrong?</p>
<pre><code>var current_index = 1;
$(document).ready(function() {
$(function() {
setInterval("selectNextStep()", 3000);
});
});
function selectNextStep() {
$("#step_"+current_index).fadeOut('slow', function() {
var next = current_index;
next = next + 1;
$("#step_"+next).fadeIn('slow', function() {
if (current_index == 4) current_index = 1;
else current_index ++;
});
});
}
</code></pre>
