Why do we need apply method inside the constructor to invoke any method defined on the prototype object?

<p>Why do we need apply method inside the constructor to invoke any method defined on the prototype object?</p>
<p>Code working:</p>
<pre><code> function Test(){

Test.prototype.add = function(){
for(var i=0; i < arguments.length; i++){
this.x.push(arguments[i]);
}
}
var t = new Test(11,12)
t.x //[11,12] this is fine
t.x.length //2 this is also fine

JQuery, $(this) not correct in fadeIn, fadeOut callback function?
|
<p>I would like to fadeOut() an image on the page and remove it from the DOM after the animation is finished. Sounds easy enough?</p>
<p>Example code (image has the id "img1"):</p>
<pre>
$("#img1").fadeOut("slow", function() { $(this).remove() });
</pre>
<p>This does does not work. When I inspect the page with Firebug the image is still there. It is just hidden.</p>
<p>Second example which should kind of flash the image:</p>
<pre>
$("#img1").fadeOut("slow", function() { $(this).fadeIn() });
</pre>
<p>Strange.</p>
<hr>
<p>Thanks for the example pages which work great and as expected.</p>
<p>The problem must be something else and only occurs in my project environment.</p>
<p>Side note: when I do a simple console.log($(this)) in my callback function the result is the window object itself?!</p>
<p>When I find out what side effects create the problem I'll update this question.</p>

Merge android.graphics.Path instances?

<p>Is it possible to merge several paths?</p>

Drawing with Paint.Style.STROKE works.
So it seems to be a problem with the Path.FillType ?</p>
<pre><code> public void drawTest3(Canvas canvas){
Path p1,p2,p3,p4;
p1 = new Path();
p2 = new Path();
p3 = new Path();
p4 = new Path();
// create 3 coordinates that form a triangle
float[] start = new float[]{(float)getWidth()/2,(float)getHeight()/2};
float[] point1 = new float[]{0.0f,(float)getHeight()};
float[] point2 = new float[]{(float)getWidth(),(float)getHeight()};
p1.moveTo(start[0], start[1]);
p1.lineTo(point1[0], point1[1]);
p2.moveTo(point1[0], point1[1]);
p2.lineTo(point2[0], point2[1]);
p3.moveTo(point2[0], point2[1]);
p3.lineTo(start[0], start[1]);
// add all 3 paths to p4
p4.addPath(p1);
p4.addPath(p2);
p4.addPath(p3);
// draw
canvas.drawARGB(0xff, 0xdd, 0xdd, 0xdd);
Paint paint = new Paint();

Why is my arguments array only having a size of 1?

<p>Why am I getting a size of 1 returned by <code>my_game.size()</code>? I thought the arguments from <code>make_game</code> would get inserted into <code>game</code> and so <code>arguments.length</code> would be 3, but apparently it's not. What is the reason for this?</p>
<pre><code>function game()
{
var args = arguments;
this.size = function() { return args.length; };
}
function make_game()
{
return new game(arguments);
}
var my_game = make_game(4, 'a', true);

Highlight specific text in specific order
|
<p>I've got this but need it to highlight in order without hovering, so more like an animation. Any ideas?</p>
<p><a href="http://jsfiddle.net/3QG3w/" rel="nofollow">http://jsfiddle.net/3QG3w/</a></p>
<p>In more detail: When the page loads I want "Client 1" to highlight and with it "Benefit 1" and "Benefit 3". Then I want it to un-highlight and "Client 2" and Benefit 2, 3 & 4 to highlight" and so on.. So it cycles through each Client highlighting the benefit for each. An animation of sorts.</p>
<p>Sorry, I'm fairly new to coding but trying my best.</p>

Confusing Java Class concept

<pre><code>class Foo {
int age;
Foo someName;
}
</code></pre>
<p>the above code will give error. While in java i can do it. Is there a special reason behind it? And how does it happen. Any good read will be helpful. </p>

<p>Would this have <strong>any</strong> effect on a case-insensitive language such as VB.NET, will there by any CLS-compliance (or other) problems if the names are only distinguishable by casing?</p>

Does PHP have the equivilant to Java 'synchronized' , or is this not required?

<p>I am familiar with Java and at the moment I am teaching myself PHP. To prevent race conditions and deadlocks, Java uses the keyword 'synchronized'.</p>

}
</code></pre>
<p>I am using prepared statements within a separate class to access my database. I wish to avoid race conditions, deadlocks etc, but I cannot see how PHP handles this.</p>

How pass reference to "this" on href javascript function?
|
<p>I have a link with this href:</p>
<pre><code>href="javascript:foo(this);"
</code></pre>
<p>when I call it "this" points to the window object, not the link. How do I pass a reference to the link?</p>
<p><a href="http://jsfiddle.net/xMGKz/" rel="nofollow">http://jsfiddle.net/xMGKz/</a></p>
<p><strong>Edit note</strong>: The question is how to pass with href, not generally - I know about onclick!</p>
<p>And not copying id and make getElementById, that's not "this", it's DOM search for certain element, no need to make it inline in HTML.</p>
<p>The anwer is: not possible.</p>

What faults are there to coding a character sheet as an enumeration?
|
<p>I am working on creating a character sheet for a RPG I'm tinkering with. I figure out all the data I need the character sheet to keep, but I am not sure if the way I am doing it is most economical in the sense of speed and resources. Right now I have an enumeration with three types: NPC, MONSTER, PLAYER. Inside the enumeration I have a class that will store and handle all getting/setting for the stats and derived attributes. Are there any disadvantages to writing it this way? Does anyone have any suggestions?</p>

Why button is not centered vertically in LinearLayout?
|
<p>I have a LinearLayout, which only contains one button. I want this button to be centered vertically and aligned to the right. I tried many ways, but I couldn't make this button centered vertically. It is always aligned to the top. I also tried to put a button in RelativeLayout, the button can not be centered vertically either. </p>
<p>The XML is as below. Is there anything wrong with this layout? Thanks.</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#E8E3E4">
<Button
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:text="More" android:layout_gravity="right" />
</LinearLayout>
</code></pre>
<hr>
<p>Changing android:layout_gravity="right" to android:layout_gravity="right|center_vertical" didn't resolve the problem in my question. </p>

How to catch a click event on a button?
|
<p>Hey everyone. .NET Developer here just getting started with Eclipse and Android.</p>
<p>Can someone show me in the simplest way possible, with the absolute fewest lines of code, how to DO something when a button is clicked?</p>
<p>My button has id <code>button1</code> and I just want to see where/how to write the <code>onClick()</code> handler.</p>
<p>So let's say I have <code>imageview1</code> set to invisible. How would I make it visible when the button is clicked?</p>
<p>EDIT:</p>
<p>Thanks everyone, but since not a single one of your examples work for me, I'll try this: Can someone please post the ENTIRE code to make this work? Not just the method, becuase when I try to use ANY of your methods I get errors all over the place so obviously something else is missing. I need to see everything, beginning with all the imports. Thank you.</p>

Issue with pointer to character array C++

<p>I have what I thought should be a very simple snippet of code to write, though I'm unable to compile for a reason which I do not understand.</p>
<p>The following simplified code will not compile:
</p>
<pre><code>char buffer[9] = "12345678";
char* pBuffer = &buffer;
</code></pre>
<p>Compiler (g++) throws the following error:</p>
<p><code>error: cannot convert 'char (*)[9]' to 'char*' in initialization</code></p>
<p>C++ isn't exactly my "native" language, but everywhere I've looked tells me this should work. Any ideas or advice is greatly appreciated.</p>

Have jQuery actively select divs whose classes live update?
|
<p>I am working my way through a jQuery book right now, and I am trying to make some basic markup for my website as practice. </p>
<p>What would be the best way to actively select the class containing lets say the word "active" at the end of it. I was going to use the live() method but after looking that up on jQuery's website, they say it's now obsolete? How else can I tell jQuery to keep looking for the class that ends with the word "active" within a parent div after the DOM finishes initially loading? </p>
<p>The reason why it needs to keep looking is, I am using some open-source jQuery slider for my front page, and it adds the word "active" onto the end of the class of the div that's currently displaying the shown image.</p>

C++ function call with the parameters unknown at compile time
|
<p>As weird as it sounds, I need to call a function in C++, for which I do not know the signature. Basically, I want to let the user specify a list of arguments, and argument types, and then attempt to call a given function with these arguments. I would then like to know if the function call worked or not, and if it (miraculously) did, what is the return value (provided that the return type is not void). Is there any way to achieve that?

Jquery .load() and page refreshes
|
<p>I've been trying to figure out what is wrong with this for the last 2 days. I have a drop down that uses autocomplete for Ids. That works fine. When an Id is selected, I'm trying to get it to load a small table that is displayed with the Id information (the <code>onSelect</code> portion below).</p>
<p>However when the Id is selected, the page is refreshed, as if I clicked on a link. I realize this is probably something small, I just can't seem to figure it out.</p>
<pre><code>var options, a;
$(document).ready(function(){
options = {
serviceUrl:'jsonExceptionRequest.cfm',
onSelect: function(value, data){
$("#claimData").load('ajaxExceptionRequest.cfm?Id=' + value);
}
};
a = $('#query').autocomplete(options);
return false;

Help Me Understand C++ Header files and Classes
|
<p>OK, So I am trying to transition from intermediate Delphi to C++ Object Oriented programing. I have read Ivar Horton's book on visual C++ 2010. I can pull off the simple console applications no problem. I get the language itself (kinda). Where I am struggling is with headers and classes. </p>
<p>I also understand what header files and classes do in general. What I am not getting is the implementation when do I use a header or a class? Do I need to create classes for everything I do? Do my actual work functions need to be in header files or in CPP files? I'm lost on the proper uses of these and could use some real world guidance from more experienced programmers.</p>
<p>I am trying to transition to windows applications using the MFC if that is helpful. </p>

Using endResponse in a Response.Redirect
|
<p>While performing a response.redirect in an ASP.NET page, I received the error:
<br /><strong>error: cannot obtain value</strong>
<br />for two of the variables being passed in (one value being retrieved from the querystring, the other from viewstate)
<br />
<br />
I've never seen this error before, so I did some investigating and found recommendations to use the "False" value for "endResponse"
<br />
<br />
e.g. Response.Redirect("mypage.aspx", False)
<br />
<br />
This worked.
<br />
<br />
My question is: what are the side-effects of using "False" for the "endResponse" value in a response.redirect?
<br />
i.e. are there any effects on the server's cache? Does the page remain resident in memory for a period? Will it affect different users viewing the same page? etc.
<br />
<br />
Thanks!</p>

Ajax Requests Saved on Browser's History
|
<p>Is there an easy way to save ajax requests into a browser's history so that when you use the back button it will preserve the last state of the DOM?</p>
<p>Websites like twitter and digg that use an ajax pager have a usability flaw where if you click next page several times then click away from the site and then return using the back button, you lose your place in the viewport since the DOM is restored to the first initial request.</p>
<p>I noticed safari actually preserves the dom after a few ajax requests on some sites.<br>
Here is an example, Goto <a href="http://13gb.com" rel="nofollow">http://13gb.com</a>, Click next a few times then click on an image and then click your back button. On webkit it preserved the last DOM state, but on gecko and ie it does not. </p>
<p>What would be the easiest way to replicate this functionality on other browsers?</p>

Anyone know an elegant function to fix name cases?
|
<p>Kindergarten 101 teaches some of us that: "The letters in your name should be lowercase, with uppercase first letters." Yet in this post-literate era, how people enter their names in web forms seems to depend on their mood, or solar flares or whatnot: All uppercase, all lowercase, mixed, upside down...</p>
<p>Philosophically, I say whatever! Occupy your name, who cares. But I have OCD clients that prefer to see data normalized, standardized, predictable. So I'm asking you guys if you've seen any well-thought-out PHP functions for case-fixing names, that take into consideration the various exceptions that <code>ucwords()</code> would totally butcher, such as:</p>
<ul>
<li>Sven-Alex Crumpet</li>
<li>Ronaldo McDonaldo</li>
<li>Boopsie O'Brien</li>
<li>J.R. Bob Dobbs</li>
<li>Francesca de los Gatos</li>
<li>YungCheng Li</li>
</ul>
<p>Any functions out there that attempt to accommodate these alphabet rebels?</p>
<p><b>UPDATE</b><br>
From Robin v. G.'s point of van-tage, there can be no script to rule them all. But I've decided that names entered entirely in lower or uppercase are likely candidates for a good scrubbing. So for these, I will do ...</p>
<pre><code> if ($name == strtoupper($name) || $name == strtolower($name)) {
$name = ucwords(strtolower($name));
}
</code></pre>
<p>It would be easy enough to modify this to fix a few likely exceptions: dashes, apostrophes, 'McD', etc. Mistakes will be made, but who will complain? Not the meek bastard who entered their name in lowercase.</p>
<p>Oh wait, my name is in lowercase...</p>

I have the JDK installed and working so dont worry about telling me that part. The book I am reading shows something like this (assuming you enter these commands in the cmd):</p>
<pre><code>save: doobee.java
compile: javac doobee.java
run: %java DooBee
</code></pre>
<p>When I follow those instructions I get this in the cmd:</p>
<pre><code>Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\James>javac -version

how to convert an int to a char C++
|
<p>Im having trouble with an assignment where I have to convert three variables of a clock (int hour, int minutes, and bool afternoon) to be converted to a string in a method. I tried converting the int to a char and then replacing each string with the char. The function is suppose to return T/F if the conversion worked or not. Here is what I have so far:</p>
<pre><code>class Time
{
private:
int hour;
int minutes;
bool afternoon;
public:
void setHour(int hr);
void setMinutes(int min);
void setAfternoon(bool aft);
int getHour();
int getMinutes();
bool getAfternoon();
bool setAsString(string time);
string getAsString();
Time(void);
~Time(void);
};
</code></pre>
<p>and</p>
<pre><code>bool Time::setAsString(string time){
char min = minutes;
char hr = hour;
char hr[0] = time[0];
char hr[1]= time[1];
char min[0] = time[3];
char min[1] = time[4];
char afternoon = time[6];
if ((hourTens > 1) || (minTens > 5)) {
return false;
} else {
return true;
}
}
string Time::getAsString(){
return false;
}

Python: Mock side_effect on object attribute

<p>Is it possible to have a side_effect on a property? If I look at the Mock documentation it seems it's only possible on object methods.</p>

<pre><code>def get_object(self):
try:
return self.request.user.shop
except Shop.DoesNotExist:
return None

need help clearing touch events between activities
|
<p><strong>Scenario:</strong></p>
<p>There are two activities...
Activity A has an imagebutton to launch an intent to show Activity B on screen.
Activity B has an imagebutton to finish() itself and cause Activity A to be shown.
These buttons are at the same location on each activity</p>
<p><strong>Problem:</strong></p>
<p>in Activity B, when I double-tap the button (instead of single tap), Activity A becomes visible but quickly shows Activity B again !</p>
<p>the second touch event seems to carry through to Activity A and it would seem that I could fix this problem by clearing some touch buffer in onCreate() of Activity A.</p>
<p>How can this be done? Or is there another fix ?</p>
<p>I've reproduced this on the emulator (2.2) and on the phone (2.3.3)</p>

<li><a href="#" class="department">Click me</a></li>
<li><a href="#" class="branch">Click me</a></li>

<p>i wanted to execute some code by clicking on the anchor tag.so i used </p>
<pre><code>$('a').click(function(){
//do something..
});
</code></pre>
<p>but it did not work out. So I used </p>
<pre><code>$('a').on('click',function(){
//do something..
});
</code></pre>
<p>also i used</p>
<pre><code>$('a').bind('click',function(){
//do something..
});
</code></pre>
<p>but they did not work either. what worked for me was</p>
<pre><code>$('a').live('click',function(){
//do something..
});
</code></pre>

Run function if user close browser
|
<p>I have problem with this function. I will explain -
I must execute function if user closes browser. This function is write in JavaScript- saveCookieScriptPrefOnLogOut().</p>
<p>I have this solutions (I writed this using info from StackOverFlow):</p>
<pre><code>var inFormOrLink;
$('a').live('click', function() { inFormOrLink = true; });
$('form').bind('submit', function() { inFormOrLink = true; });
$(window).bind('beforeunload', function(eventObject) {
var returnValue = undefined;
if (! inFormOrLink) {
saveCookieScriptPrefOnLogOut();
}
saveCookieScriptPrefOnLogOut();
return true;
});
</code></pre>
<p>Problems with this solution is: every browser display windows with question "Do you really want to close?"</p>
<p>I have to hide this information/window. Second problem (less important but still) - FF and IE runs this function when I click on Link or form submit. I need to ignore a links and form submit.</p>
<p>solution must be crossbrowser solution (IE, Chrome, FF on windows. The most important is IE). I can use PHP and javascript.</p>
<p>Can you give me any answer how I solve these problems?</p>

Cloning Input Boxes

<p>Hi I have a input box that needs to be cloned up to six times, according to the .clone() function, i can do this, but if the input name has to be changed, how to do this.</p>
<p><a href="http://api.jquery.com/clone/" rel="nofollow">http://api.jquery.com/clone/</a></p>
<pre><code><label for="input">
<input name="input" id="input" type="text">
</label>
<a href="#" onClick="cloneInput()">Add Another Input</a>
</code></pre>
<p>So let's say when a new input is created it should add an increment to the name and id, ie: <code>name="input2"</code> <code>id="input2"</code> and so on, each time the object is cloned. </p>
<p>Anyone have any suggestions on the best/easiest way to do this with jQuery? </p>

How exactly does Java wait() method work?

<p>Consider that thread 1 is running following code:</p>
<pre><code>while (true) {
synchronized (this) {
wait();
...Do Something ...
}
}
</code></pre>
<p>And lets say we have thread 2 that notifies thread 1, ie:</p>
<pre><code>synchronized (thread1)
thread1.notify();
}
</code></pre>
<p>My question is lets say thread 1 got woken up, and is doing something (so its running currently). Then lets say thread2 does notify on thread1 while thread1 is running.
Will thread1 run again when it finishes "do something"? Or will it just sleep instead?</p>
<p>Is my question clear enough?</p>

Clicking on an icon to open and close the tooltip

<p>I'm trying to figure out how you can open the tooltip by clicking on the icon as well as closing it. I've been looking at some of the discussion here, but none of them doesn't seem to work at my end. Here is what I have so far:</p>
<p><strong>HTML</strong></p>
<pre><code><span class="info">
<img alt="aImage" src="images/aImage.png" />
<span style="display: none;" class="stuff">something something</span>

$(".info").tooltip({tooltipcontentclass:"stuff"})
});
</code></pre>
<p>For this, of course, this will only show the tooltip if the mouse is hovering over it and closes it if you hover it away. I know it's not much, but this is the best I can do here. Please let me know if there is a way for opening and closing it by clicking.</p>

<p>Another method I tried was:</p>
<pre><code>$("#fscaTotals td").filter(":contains('\\(')")
</code></pre>
<p>This throws error "Exception thrown and not caught". It seems to work for other characters though. example: . , ; < > </p>
<p>so, how do you escape parentheses in jquery?</p>

Unable to type in textbox even with focus set
|
<p>I have a flash keyboard (not written by me and I know no flash) which is used by the users to type in to the web forms. The keyboard works fine and I am able to fill the fields properly. </p>
<p>When the keyboard obscures any field, I am scrolling the document (in EnsureNotObscured() method) so that input field is not obscured. This is where I am getting the issue. After scrolling the document, I can see that the input field still has the focus (cursor blinks) but when I type nothing appears.</p>
<p>IF I click the mouse in that field again then I am able to type in that field. What could be the reason for this behavior? I even tried explicitly setting focus using
document.getElementById(field.id).focus() after scrolling the document in EnsureNotObscured() and still it doesnt work. I even tried doing blur of the field and then setting focus back but no success. </p>
