Sum of a string of one-digit numbers in javascript?
|
<p>I'm trying to write a script that adds the left side of a string and validates it against the right side.</p>
<p>For example:</p>
<pre><code>var left = "12345"
var right = "34567"
</code></pre>
<p>I need to do some sort of sum function that adds 1+2+3+4+5 and checks if it equals 3+4+5+6+7.</p>
<p>I just don't have a clue how to do it.</p>
<p>I think I need to use a for loop to iterate through the numbers such as
for (var i = 0, length = left.length; i < length; i++)</p>
<p>But I'm not sure how to add each number from there.</p>
<p><em><strong>EDIT</em></strong> the var is actually being pulled in from a field. so var left = document.blah.blah</p>

ASP.NET Error: Could not load file or assembly App_Web_z9w33txs
|
<p>How did you get rid of these annoying ASP.NET errors:
Could not load file or assembly 'App_Web_z9w33txs, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'</p>
<p>This has only happened to me once before. It seems like it is related to ASP.NET caching some assembly dynamically, but not recompiling it for some reason. Thoughts? How do you fix this? What causes it?</p>
<p><strong>More Info:</strong>
This is happening to a WCF Service being called via Ajax from my Default.aspx page.
The Default.aspx page loads fine.</p>
<p><strong>removed stack trace</strong></p>
<p><strong>Final Update:</strong><br />
So this is happening to me at least 5 times a day now.
I have to shutdown the app pool.<br />
Go into C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
and deleted the files here
Then restart the app pool.
Anybody else run into something like this? Should I just break down and create a support case with Microsoft.</p>

Elegant PHP solution to replace a specific substring
|
<p>There is the string</p>
<p>"a cat is a cat, but a dog is not a cat"</p>
<p>I wish to replace only the second "cat" substring with another word, preferably using native php functions. The solution must be general, for example to be able to replace the first 'cat' string or the third.</p>
<p>Oh well, maybe somebody will find this and realise the complexity of the problem and reopen it again.</p>

Module pattern | Private access to passed in reference
|
<p>Suppose I have someFunction() that has a public prototype function giveMeAccess() available to the user. </p>
<p>Now suppose I want this prototype method to have access to Private variables inside the function that returned it..</p>
<p>Is there any way to do this?</p>
<p>Yes this has an application as strange as it might seem. I need this info. to model a class hierarchy.</p>
<pre><code>var privateMaker = function ( give_me_access ) {
var Private = {},
someFunction = function(){};
someFunction.prototype = {
public_access: give_me_access
};
return someFunction;
}
</code></pre>
<p><strong>Use</strong></p>
<pre><code>var Func1 = new privateMaker();
var private_loot = Func1.public_access();
</code></pre>
<p><strong>Question</strong></p>
<p>How do I give giveMeAccess() access to Private inside of privateMaker()? </p>
<p>Note the prototype function is passed in to the outer function instead of defined in the function as usual. This is the weird caveat.</p>
<p>If this is impossible with this model...then state that as an answer.</p>

<p>i have created 2 counters one as </p>
<p>PerformanceCounterType.AverageCount64 </p>
<p>and the seconds as </p>
<p>PerformanceCounterType.AverageBase</p>
<p>i am adding them ine after the other (the base come second)</p>

<p>on second process i want to display the counter so when i am calculating</p>
<pre><code>Single numerator = (Single)s1.RawValue - (Single)s0.RawValue;

How can I use a timer to delay a specific task not associated with the timer class (java.util.timer)?
|
<p>I am making a text-based RPG for a personal project in Java. In the game the protagonist will have at his/her disposal the ability to use a spell or ability. I would like to add a cool down to the aforementioned spell or ability. I have researched both the javax.swing.Timer and java.util.Timer classes but have not found a way to go about using this cool down. I am not using threads or daemons (primarily because I don't think I need to and I have zero experience with them). </p>
<p>Any help or ideas on how to go about this would be appreciated, thanks.</p>

How can I find the parent tr of a td using jQuery?
|
<p>I have the following:</p>
<pre><code> tdToPad = tds.filter('[id^="input_Title_"]')
pad = 60;
tdToPad.css('margin-left', pad);
</code></pre>
<p>What I would like to do is to remove any class that starts with "X-" and give the row that is contained by "tdToPad" a class of "X-" + pad. </p>
<p>Something like:</p>
<pre><code><tr class='X-60'>
<td>
</td>
</tr>
</code></pre>
<p>Being that toToPad refers to the td element in a row. How can I give the parent tr the class "X-" + pad ? I think I need something like the following but if that's the correct way to do it then how can I remove elements already there with a class of "X-" somevalue and then give this element the correct class?</p>

Why is Class.getAnnotation() requiring me to do a cast?
|
<p>I'm using Java 1.6.0_25.</p>
<p>I have an annotation defined:</p>
<pre><code>@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface Resource {
String value();
}
</code></pre>
<p>And later when I use getAnnotation:</p>
<pre><code>Resource resource = (Resource)cls.getAnnotation(Resource.class);
</code></pre>
<p>the compiler and IDE agree that I must cast the result, but getAnnotation is declared in the Java 1.5 documentation as:</p>
<pre><code>public <A extends Annotation> A getAnnotation(Class<A> annotationClass);
</code></pre>
<p>Since Resource.class is of type Class, it seems to me that this means that cls.getAnnotation(Resource.class) should return type Resource, and I should need to cast.</p>
<p>All examples I've found using getAnnotation don't have a cast, so I must be doing something wrong.</p>

IPHONE - Use multiple views
|
<p>I have to make an application with six views, which can be accessed to by bar button items on a toolbar. </p>
<p>I'm really new at this.
I have a view controller and a XIB file for each view, with six functions (goToView1, goToView2, ..., goToView6).</p>
<p>Here is an example :</p>
<pre><code>SecondViewController *secondview;
-(IBAction)goToView2 {
secondview = [[SecondViewController alloc]
initWithNibName:@"SecondViewController" bundle:nil];
[self.view addSubview:secondview.view];
}
</code></pre>
<p>But as you can see, if I want to go from view3 to view2, I'm not deleting the view3 from the stack : I'm just adding the view2 over it.
So here's my problem, how do I "delete" my view before using addSubView ?
I tried with removeFromSuperView, but I think I'm not using it right.</p>
<p>Thanks for helping, as I said I'm really new and I am aware it can be a stupid question :/</p>

Link to external php file (for proprietary reasons)
|
<p>So we've got a pretty nifty little PHP app. People have been interested in "leasing" it under a different name.</p>
<p>However, with the current setup - any "top tier admin" (which they would have to be) can view the PHP files.</p>
<p>My boss is a tad concerned with that. Would it be possible (or rather, SMART) to link to external PHP files on our server instead?</p>
<p>So instead of</p>
<p><strong>index.php contents:</strong></p>
<pre><code><?php include('/lib/header.php'); ?>
</code></pre>
<p>and consequently </p>
<p><strong>header.php contents:</strong></p>
<pre><code><?php /*Stuff I don't want you seeing*/ ?>
</code></pre>
<p>would it be possible (and if so, smart) to do something like this</p>
<p><strong>index.php contents:</strong></p>
<pre><code><?php include('http://site-i-control.com/lib/header.php'); ?>
</code></pre>
<p>so they couldn't see or modify the contents of header.php?</p>

I was trying to replicate a bug by using the same instance of SimpleDateFormat across multiple threads. However I got stuck with another problem and did not find any answers to it. </p>
<p>This simple code block replicates the issues I am seeing.</p>
<pre><code>DateFormat d1 = new SimpleDateFormat("ddMMyyyy");
DateFormat d2 = new SimpleDateFormat("ddMMyyyy");
DateFormat d3 = new SimpleDateFormat("ddMMyy");
System.out.println("d1 = " + d1);
System.out.println("d2 = " + d2);
System.out.println("d3 = " + d3);
</code></pre>
<p>The results of this operations under java 7 (1.7_0_21) is as follows </p>
<pre><code>d1 = java.text.SimpleDateFormat@c5bfbc60
d2 = java.text.SimpleDateFormat@c5bfbc60
d3 = java.text.SimpleDateFormat@b049fd40
</code></pre>
<p>As you can see that although I am creating new objects for d1 and d2 they end up being the same reference. d3 ends up being a new instance as pattern is different.<br/></p>
<p>Does java compile/runtime do this optimization? Any pointers will be helpful</p>

Self executing function as object property value in javascript
|
<p>Is it possible to have a self executing function which is an objects property value assign values to other properties in the object?</p>
<p>e.g. - what I would like to do is this:</p>
<pre><code>var b={
c:'hi',
d:null,
e:new function(){this.d=5}
};
</code></pre>
<p>But the "this" inside the new function seems to refer to b.e. Is it possible to access the b.e parent (i.e. b) from inside the function?</p>

Why new String(bytes, enc).getBytes(enc) does not return the original byte array?
|
<p>I made the following "simulation":</p>
<pre><code>byte[] b = new byte[256];
for (int i = 0; i < 256; i ++) {
b[i] = (byte) (i - 128);
}
byte[] transformed = new String(b, "cp1251").getBytes("cp1251");
for (int i = 0; i < b.length; i ++) {
if (b[i] != transformed[i]) {
System.out.println("Wrong : " + i);
}
}
</code></pre>
<p>For <code>cp1251</code> this outputs only one wrong byte - at position 25.<br>
For <code>KOI8-R</code> - all fine.<br>
For <code>cp1252</code> - 4 or 5 differences.</p>
<p>What is the reason for this and how can this be overcome?</p>
<p>I know it is <em>wrong</em> to represent byte arrays as strings in whatever encoding, but it is a requirement of the protocol of a payment provider, so I don't have a choice.</p>
<p><strong>Update:</strong> representing it in <code>ISO-8859-1</code> works, and I'll use it for the <code>byte[]</code> part, and <code>cp1251</code> for the textual part, so the question remains only out of curiousity</p>

How to avoid image stretching in imageview

<p>I have a image with 320x480 and i am running the application in device with 320x480.

for in loop and the delete operator
|
<p>I noticed that when enumerating the properties of an object, that it seems like a snapshot of the current properties is taken at start of the loop, and then the snapshot is iterated. I feel this way because the following doesn't create an endless loop:</p>
<pre><code>var obj = {a:0,b:0}, i=0;
for (var k in obj) {
obj[i++] = 0;
}
alert(i) // 2
</code></pre>
<p>demo <a href="http://jsfiddle.net/kqzLG/">http://jsfiddle.net/kqzLG/</a></p>
<p>The above code demonstrates that I'm adding new properties, but the new properties won't get enumerated. </p>
<p>However, the delete operator seems to defy my snapshot theory. Here's the same code, but deleting a property before it gets enumerated.</p>
<pre><code>var obj = {a:0,b:0}, i=0;
for (var k in obj) {
i++;
delete obj.b;
}
alert(i) // 1
</code></pre>
<p>demo <a href="http://jsfiddle.net/Gs2vh/">http://jsfiddle.net/Gs2vh/</a></p>
<p>The above code demonstrates that the loop body only executed one time. It would have executed twice if the snapshot theory were true.</p>
<p>What's going on here? Does javascript have some type of hidden iterator that it uses, and the delete operator is somehow aware of it?</p>
<p>-- I realize that I'm assuming something about iteration order- specifically that iteration occurs based off of property insertion time. I believe all browsers use such an implementation.</p>

How would I implement a tournament like this? C++
|
<p>I have an array of 16 (example below). Each match of the tournament involves displaying two restaurants, prompts to choose his favorite one, and removing the losing restaurant from the tournament.
It is like a bracket system; i.e., a restaurant does not reappear in another match until all other restaurants have also appeared in a match for that round). So start with 8 matches, then 4, then 2.
Do not allow the tournament to begin unless the number of restaurants is equal to 16.
I am pretty new to C++. Anyone have a decent outline or suggestions/paths I should look at?</p>

Write program to download .gz file in java?
|
<p>I've been trying to write a program in java that can download a number of .gz files from an ftp server online for me. Here's what I've been using:</p>
<pre><code>public static void main(String[] args) throws IOException {
URL url = new URL("ftp://ftp.ncbi.nih.gov/pub/geo/DATA/SOFT/by_series/GSE10/");
URLConnection con = url.openConnection();
BufferedInputStream in = new BufferedInputStream(con.getInputStream());
FileOutputStream out = new FileOutputStream("GSE10_family.soft.gz");
int i = 0;
byte[] bytesIn = new byte[3000000];
while ((i = in.read(bytesIn)) >= 0) {
out.write(bytesIn, 0, i);
}
out.close();
in.close();
}
</code></pre>
<p>The program runs and downloads the file just fine. However, when I try to uncompress the .gz file, it unzips as a .cpgz file which then creates an endless cycle of .cpgz to .gz and so forth.</p>
<p>When I download this file manually, it unzips and everything perfectly fine, so I know it isn't a problem with the file.</p>
<p>Any suggestions would be greatly appreciated! Thank you so much!</p>

Jquery using :after selector
|
<p>I am currently making a menu and because the menu is an oddshape with a glow around the edge I need to put a blank block over the top to hide the unwanted glow on the overlap. I am creating this using the :after selector on the li tags for the menu and the code to do so works fine. </p>
<p>My problem however is that I can only make it apply to none or all of the menu items at once by toggling the display attribute, what I want however is for the :after selector to only be applied to the current list item. </p>
<p>Each list item has a unique id but I can't seem to work out how to use the :after selector on a specific list item within jquery.</p>
<p>Thanks in advance for any help. Sorry if this is unclear.</p>
<p>HTML Code</p>
<pre><code><ul id="menu">
<li id="0">link 1</li>
<li id="1">link 2</li>
<li id="2">link 3</li>
</ul>
</code></pre>
<p>CSS for the list item</p>
<pre><code>#menu li{
float:left;
margin:0 20px 0 0;
height:87px;
z-index:1;
position:relative;
background: #f8f8f8;
cursor:pointer;
border:1px solid #CCC;
border-bottom:none;
}
#menu li:after{
display:none;
content: '';
position: absolute;
top: 0;
bottom: -5px;
left: 0;
width: 291px;
height:10px;
margin-top:109px;
background: #f8f8f8;
}
</code></pre>
<p>I thought it would be as simple as putting something like </p>
<pre><code>$$('li[id="0"]:after').show();
</code></pre>
<p>or maybe </p>
<pre><code>$$('li[id="1"]:after').css("display" : "block");
</code></pre>
<p>but these does not work.</p>

Too many local variables in ASP.NET

<p>I wrote a control, and use a tool to do the code analysis. There is a test that I didn't pass. Avoid excessive locals, <a href="http://msdn.microsoft.com/library/ms182263(VS.90).aspx" rel="nofollow">http://msdn.microsoft.com/library/ms182263(VS.90).aspx</a>.</p>
<p>In my CreateChildControls function, I built a big table with lots of field. I need to create a lot of TableRow and TableCell to construct the table. But these are not field or property of control. Thery are local variables in the function, which are created dynamically.</p>
<p>Should I make these TableCells and TableRows as fields of the control? Or I just keep them as the local variables in the CreateChildControl function?</p>

//also wont let me enter data here

<p>Important to mention that I do not send SMS from my app, I just should listen when SMS is sent from the device.</p>

Should I use a class of functions or a namespace of functions?
|
<p>Say I want some functions to deal with some file, and I was considering 2 options.</p>
<p>1) Create a class like <code>SavedDataHandler</code> that a user could use like this....</p>
<pre><code>// Note that SavedDataHandler has no members. It just has functions that operate on a
// resource ( the file)
SavedDataHandler gameSave;
gameSave.SaveData( arg1, arg2 ); // to save data
gameSave.DeleteSave(); // Delete the save
...
</code></pre>
<p>2) Create a namespace of functions</p>
<pre><code>namespace SavedDataHandler {
SaveData( ... ) { ... }
DeleteSave( ... ) { ... }
...
}
</code></pre>
<p>that a user would call like </p>
<pre><code>SavedDataHandler::SaveData( arg1, arg 2 );
SavedDataHandler::DeleteSave();
</code></pre>
<p>What would be preferred? </p>
<p>P.S. I thought about this when I was thinking about Scott Meyer's recommendation to prefer non-member non-friend functions to member functions. I've run into decisions where I have a function (usually some private member function to help the class do stuff), that could easily be made into a non-member since it doesn't operate on class privates. </p>
<p>However, the function is only used by that one class. Of course, the program might evolve to a point where another class may need it, but I find it hard to find a place for these non-member functions. It's easy when you have a lot of functions with a general purpose, but I find single non-member functions hard to organize into a specific place, and find that leaving it as a member keeps things clean. Any tips regarding this issue?</p>

How to exclude previous months of the current month?
|
<p>I have the following PHP that displays the month then an IF statement inside the foreach that says IF the month is February then do the <code>li</code>:</p>
<pre><code>$months = array('1' => 'January', '2' => 'February', '3' => 'March', '4' => 'April', '5' => 'May', '6' => 'June', '7' => 'July', '8' => 'August', '9' => 'September', '10' => 'October', '11' => 'November', '12' => 'December');
echo '<li><a class="by_month"></a><ul class="monthby" name="monthby">';
foreach($months as $month => $monthtitle):
if ($month == '2'){
echo '<li title="'.$monthtitle.'" rel="'.$month.'"><a href="#" title="'.$monthtitle.'">'.$monthtitle.'</a></li>';
}
endforeach;
echo '</ul></li>';
</code></pre>
<p>How do I modify the above code to say IF the month is February, then exclude any previous months. Basically, I want to create a list of the current month and upcoming months but exclude past months of the year.</p>
<p>So, for example, if the month was November, the list would ONLY show November and December. It would exclude all previous months.</p>
<p>How can I do this? I image I need to do something with an IF statement, like I sort of started but using <code>date('n')</code> to get the current month then ignore previous months of the current month.</p>

Javascript scope help
|
<p>I am relatively new to javascript so please be patient if what i am asking is completely stupid!</p>
<p>I am trying to make a simple module. Inside the module i want to have a config object that holds settings for the module. I am also using jquery. The jquery selectors work only when in a function directly in the main object/module.</p>
<p>I understand that javascript has functional scope so I am suprised that I cannot use the jquery selectors anywhere inside the module.</p>
<p>EDIT:
I want to be able to directly set all of my configs inside the configs object using jquery selectors. This way i keep all the messy stuff inside one place and can then access configs.whatever throughout the rest of the module. At the moment jquery selectors do not work inside the configs module.</p>
<pre><code> var OB = function() {
var configs = {
'mode' : 'test',
'numOfSelects' : $('.mySelect').find('select').length, // This doesnt work
}
var getMode = function() {
return configs.mode;
}
function init() {
alert(configs.numOfSelects); // This alerts 0 until the following line
alert($('.mySelect').find('select').length); // This correctly alerts 2
};
var handlers = {
successHandler : function() {
alert("Success");
},
errorHandler : function() {
alert("error");
}
}
return {
init : init,
getMode : getMode
}
}( );

I am loading the controls dynamically when a tab is selected this improves the performance a lot but once all the tabs are loaded with the controls like RadGrid, griviews etc. My page becomes too heavy which causes lagging, slow performance when switching between the tabs. As my user will be using this application on IE 8 I have to code only for IE 8. How can i improve UI performance?</p>

How to upgrade Android 1.5 R3 SDK to 2.2?
|
<p>I haven't worked on Android development for more than a year now. The latest SDK I have on my XP machine is 1.5 R3. I'd like to update to the 2.2 SDK but the android.com guide does not apply to the SDK I have installed. For example the AVD Manager from eclipse does not show specified dialog.</p>
<p>Any one upgraded his SDK please let me know what to do.</p>

'HTTP_HOST' not being evaluated correctly?
|
<p>I use php scripts when there are errors (like 400,404,403,etc), to email me and advise of what is being attempted.</p>
<p>I noticed on a 400 error, the 'from' and 'to' didn't contain my domain name, but another domain name. This is some of the code I use ..</p>
<p>PHP Code:</p>
<pre><code>$http_host = $_SERVER["HTTP_HOST"];
$http_host = str_replace("www.", "", $http_host);
$from = "From: webmaster@" . $http_host . "\r\n";
$to = "From: webmaster@" . $http_host . "\r\n";
</code></pre>
<p>The var $http_host had the other domain name there. Fortunately, the email bounced back, so I became aware of the problem. Here is the web access logs entry</p>
<pre><code>94.102.51.246 - - [23/Feb/2013:16:17:49 +1100] "GET http://24x7-allrequestsallowed.com/?...RWJWS_FA%40FQN HTTP/1.1" 400 2815 "-" "Mozilla/5.0 (Windows NT 6.1; rv:16.0) Gecko/20100101 Firefox/16.0"
</code></pre>
<p>It seems <code>$_SERVER["HTTP_HOST"]</code> was evaluated to '24x7-allrequestsallowed.com'</p>
<p>I'm mystified how this was parsed as a URL, but more uneasy that $_SERVER["HTTP_HOST"] wasn't set to the 'proper' domain name.</p>

Why does PHP post increment not behave as expected when in an array [ ] operation?
|
<p>My Question is why does the post increment not function on the first element but then works as expected when it is contained within an array [ ] element ? </p>
<p>Here is a snippet of what I was doing that behaves unexpectedly:</p>
<p>When I use this code ...</p>
<pre><code>$lessonIndex = 0;
$EventArray[$lessonIndex]['Title'] = 'Lesson 1';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex++]['Title']]['Start'];
$EventArray[$lessonIndex]['Title'] = 'Lesson 2';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex++]['Title']]['Start'];
$EventArray[$lessonIndex]['Title'] = 'Lesson 3';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex++]['Title']]['Start'];
</code></pre>
<p>The $EventArray[$lessonIndex] contents will be skip index 0 then index 1 will get what was destined for index 0 and the increment proceeds as expected through the rest of the code, but with the results being off by one.</p>
<p>If I do this instead:</p>
<pre><code>$lessonIndex = 0;
$EventArray[$lessonIndex]['Title'] = 'Lesson 1';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex]['Title']]['Start'];
$lessonIndex++;
$EventArray[$lessonIndex]['Title'] = 'Lesson 2';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex]['Title']]['Start'];
$lessonIndex++;
$EventArray[$lessonIndex]['Title'] = 'Lesson 3';
$EventArray[$lessonIndex]['Start'] = $TimeArray[$EventArray[$lessonIndex]['Title']]['Start'];
$lessonIndex++;
</code></pre>
<p>Everything works as expected.</p>

windows-7: could not run android apps on device
|
<p>I'm trying to import android applications from other computers. after sometime they're running on emulator finally now but not on the device .
probably the reason is the driver I installed , because adb devices did not recognize the device so I installed this manually and still Bluetooth Peripheral Device not installed when I check in device manager!</p>
<p>at first it gave me this error : <code>the app stopped running unexpectedly !</code> </p>
<p>now the error is :</p>
<pre><code>Re-installation failed due to different application signatures.
You must perform a full uninstall of the application. WARNING: This will remove the application data!
Please execute 'adb uninstall com.newboston.aida.android2' in a shell.

debug_zval_dump and refcount

<p>Is there any way to get the <em>refcount</em> value reported by <strong>debug_zval_dump</strong> without all the additional information returned by that function; e.g. by an alternative function or some truncation of its output? I am using the <em>refcount</em> as per the suggested solution to the problem <a href="http://stackoverflow.com/questions/4817562/detecting-whether-a-php-variable-is-a-reference-referenced">Detecting whether a PHP variable is a reference / referenced</a>. As such, all I require is the reference count. The structure I am examining is huge so (a) getting the entire structure seems like overkill and (b) I believe I've seen cases where the size has caused problems and bypassing the output buffer (NB: No *chunk_size* had been set for the ob_start).</p>

Question about when a script is executed after appending it
|
<p>In my code, I have javascript that dynamically adds another script to the page:</p>
<pre><code>created_script=document.createElement('script');
created_script.src='other_script';
created_script.type='text/javascript';
document.head.appendChild(created_script);
</code></pre>
<p>in this 'other script', I have a function called reloader().</p>
<p>The problem I'm having is that right after I dynamically add the script, I try to call the function reloader(), but I'm getting a reloader is not defined error.
Here's is like what I am doing:</p>
<pre><code>created_script=document.createElement('script');
created_script.src='other_script';
created_script.type='text/javascript';
document.head.appendChild(created_script);
reloader();
</code></pre>
<p>Can someone explain to me why this doesn't work and how should I fix this so that reloader() can be called after appending the script in a single dynamic call (if possible at all)?</p>

Prevent orientation change when users pushes display-turn-off/on button
|
<p>I've got an activity that is in a landscape mode - it's a player. Whenever I hit display-off button activity gets recreated and the screen goes black. After that I hit display-on to bring the interface back and the activity gets recreated again.</p>
<p>I guess this is because on my samsung i9001 display button not only shuts down the display but also brings that system-desktop to the foreground - so it's the first orientation change that causes activity recreation. Furthermore, when display gets active again and the activity starts it needs to change orientation/create activity again(not sure about it).</p>
<p>My question is how do I prevent the first recreation of the activity when I hit display-off. Is it possible ?</p>

Detect when element is less than 100px from top of window, change CSS

<p>I'm trying to make it so that when <code>div.projectsgrid</code> is < 100px from the top, jQuery will see if <code>div.selectedwork</code> has css background-color #ffffff. If not, it will set its background-color to #ffffff. Once the user scrolls back up and <code>div.projectsgrid</code> is more than 100px from the top, jQuery will remove the background color. I have the following code, which isn't working:</p>
<pre><code>$(window).scroll(function(e){

Dynamic bulleted list
|
<p>This is what I'm trying to do but I'm a jquery rookie.</p>
<p>When the page loads I have jquery calls
<code>levelone.php</code> which print something like <code>BEACH{!}OFFICE{!}HOME{!}</code>
and creates my first bullet level.</p>
<p>When clicking on a bullet how can I call
<code>leveltwo.php?lvlone=HOME</code> which would create new bullets with
something like: <code>BED ROOM{!}KITCHEN{!}</code> and so on </p>
<p>Same on the new bullets
<code>levelthree.php?lvlone=HOME&lvltwo=KITCHEN</code> which would create new bullets with
something like: <code>TABLE{!}CHAIR{!}</code> and so on</p>
<p>My code so far:</p>
<pre><code>$(document).ready(function(){
$.get("load_locations.php", function( my_var ) {
var my_varspl = my_var.split('{!}');
$('#myDiv').append("<ul id='newList'></ul>");
for (var i = 0, e = my_varspl.length; i < e; i++) {
if(my_varspl[i]!=''){
$("#newList").append('<li>'+my_varspl[i]+'</li>');
}
}
});
});
</code></pre>

ASP.net-Listbox not retaining selected values between postbacks
|
<p>I have a Listbox getting populated when the page loads itself and also in postbacks. Some items are already selected in that listbox even when the page loads or postbacks. I have to select one or more items in that textbox in addition to the selected one.</p>
<p>Till this point, it works perfectly, but the problem is that when i click an "update" button to save the newly added items, then also the page postbacks and so the list box get populated again. This will loose the newly selected items and none of the newly selected items will be saved.</p>
<p>So what should i do in order not to loose the newly selected items when i click the "update" button.</p>
<p>Note:- I need to populate the listbox on postbacks also. So the population of that listbox on postbacks cannot be discarded.</p>
<p>Kindly help me. I am new to ASP.net.</p>
<p>Thanks in Advance</p>
