1,161,922 | 1,161,923 | Displaying real time | <p>I am currently displaying date/time on my webpage using the date function PHP provides.
However, using this function, the date/time will only be updated when reloading the page. I wish to have the date/time updated every second instead.</p>
<p>I assume I have to use either javascript or jQuery/ajax for this, however I have no clue on how to do this. I was hoping anyone here could give me some advice.</p>

4,619,251 | 4,619,252 | Java: updated class files not used | <p>I'm developing a Java program through Eclipse locally, and debugging on a remote machine. Whenever I make a change to my program, I copy the corresponding class file to the bin directory on the remote machine. I run my program (a simulator) through a python script via the OS.system command.</p>
<p>The problem is that my program <em>sometimes</em> does not use the updated class files after they have been moved over. </p>
<p>The problem persists even if I log out and back into the remote machine. What's really strange is that, as a test, I deleted the bin directory entirely on the remote machine, and was still able to run my program. </p>
<p>Can anyone explain this? </p>

<p>The first line uses jQuery Easy Background Resize: (ref: <a href="http://johnpatrickgiven.com/jquery/background-resize/" rel="nofollow">http://johnpatrickgiven.com/jquery/background-resize/</a>)</p>
<p>In the HTML, you put something like this:</p>
<pre><code><!-- This gets positioned absolutely so place it anywhere. -->
<div id="body-background"><img src="image/bg.jpg" alt="Bg"></div>

<p>The problem I'm having is that the image takes so long to load the first time, the animations don't fire...and skip to the end. Anyway I can delay the animation till after the resize is complete?</p>

I know that it decouples the buisness logic from the design but what is the significance of the XML other than that?</p>
<p>Also I would like to know the <strong>significance of autogenerated <code>R.java</code> file</strong> in this. All I know that it is generated according to the changes in the resources and that it helps us to access the widgets and resources through their ids.</p>
<p>It would be great if someone could give a clear idea on these two aspects.</p>
<p>P.S.: I haven't put these questions as two different ones because I believe that the answers are interelated.</p>
<p><strong>Edit</strong>:(More Info)
Unlike what everyone said about the xml being easy and efficient.Here is what i read from Hello Android from Ed Brunnette which made sense.</p>
<p>Android is optimized for mobile devices with limited memory and horsepower, so you may find it strange that it uses XML so pervasively. <strong>After all, XML is a verbose, human-readable format not known for its brevity or efficiency, right?</strong></p>
<p>Although you see XML when writing your program, <strong>the Eclipse plug-in invokes the Android resource compiler, aapt, to preprocess the XML into a compressed binary format.**It is this format, not the original XML text, that is stored on the device</strong></p>
<p>If you know more on this please add on</p>

This animation is quite smooth on Chrome and IE (v9), however it is very choppy on Firefox. The whole idea is to animate the border without moving the div itself (referring back to <a href="http://stackoverflow.com/questions/6313847/jquery-animate-border-without-moving-div">this</a> question). Question is, any possible way to achieve the same animation but in a smoother fashion (like that in Chrome/IE) in Firefox? </p>
<p>This is the case even if you animate just one side of the <code>div</code>, so it's not because we are trying to animate every side at once. If we look at <a href="http://jsfiddle.net/c3Fw8/" rel="nofollow">this fiddle</a> in Firefox, it seems that the margins being animated is not too smooth, which seems to be the problem. </p>

2,816,177 | 2,816,178 | jQuery: Can't cache onclick handler? | <p>I've got a step-by-step wizard kind of flow where after each step the information that the user entered for that step collapses down into a brief summary view, and a "Go back" link appears next to it, allowing the user to jump back to that step in the flow if they decide they want to change something.</p>
<p>The problem is, I don't want the "Go Back" links to be clickable while the wizard is animating. To accomplish this I am using a trick that I have used many times before; caching the <code>onclick</code> handler to a different property when I want it to be disabled, and then restoring it when I want it to become clickable again. This is the first time I have tried doing this with jQuery, and for some reason it is not working. My disabling code is:</p>
<pre><code> jQuery.each($("a.goBackLink"), function() {
this._oldOnclick = this.onclick;
this.onclick = function() {alert("disabled!!!");};
$(this).css("color", "lightGray ! important");
});
</code></pre>
<p>...and my enabling code is:</p>
<pre><code> jQuery.each($("a.goBackLink"), function() {
this.onclick = this._oldOnclick;
$(this).css("color", "#0000CC ! important");
});
</code></pre>
<p>I'm not sure why it's not working (these are good, old-fashioned onclick handlers defined using the <code>onclick</code> attribute on the corresponding link tags). After disabling the links I always get the "disabled!!!" message when clicking them, even after I run the code that should re-enable them. Any ideas?</p>
<p>One other minor issue with this code is that the <code>css()</code> call to change the link color also doesn't appear to be working.</p>

1,953,353 | 1,953,354 | Progress dialog during tab switch | <p>When the user switches from tab A to tab B it takes a long time (6 seconds), so I put in a progress dialog to let the user know that the app is working on it. The timeline is as follows:</p>
<ol>
<li>Activity B onCreate - creates ProgressDialog and puts long tasks in a background Thread.</li>
<li>Activity B onStart</li>
<li>Activity B onResume</li>
<li>Activity B appears on the screen</li>
</ol>
<p>This all works great with one "minor" snafu- the app intermittently crashes because the onResume function references something that is created by the background Thread. It is, in other words, a classic race condition.</p>
<p>To fix the race condition I did a "join" on the thread right before the reference in onResume, but that makes the progress dialog not show up until the background thread is done (i.e. it shows up for a split second and then goes away) and the app acts like it is hung while the background thread is working. Apparently the progress dialog cannot show up until onResume completes.</p>
<p>My question is this: how can I get the ProgressDialog to show up without crashing the program? Or do I need to either get the offending reference out of onResume or live with the app acting hung?</p>

3,397,295 | 3,397,296 | Problems with unbinding a function by handler | <p>I have html like this:</p>
<pre><code><div>
<input type="checkbox" id="checkbox", checked="checked"/>
<label for="checkbox">Copy values</label>
</div>
<div>
<input id="source" type="text"/>
</div>
<div>
<input id="target" type="text"/>
</div>
</code></pre>
<p>And I'm trying to implement jQuery code to copy value from <code>source</code> input to <code>target</code> one, only when the checkbox is checked. Here's my code:</p>
<pre><code>var checkbox = $("#checkbox");
var source = $("#source");
var target = $("#target");
var bindFunction = function () {
var copyValue = function () {console.log("asd");
target.val(source.val());
}
if (checkbox.is(":checked")) {
source.bind("keyup", copyValue);
}
else {
source.unbind("keyup", copyValue);
}
}
checkbox.bind("change", bindFunction);
bindFunction();
</code></pre>
<p>However, it does not work as expected - for some reason the <code>copyValue</code> function doesn't get unbound. What am I doing wrong?</p>

3,947,896 | 3,947,897 | how to dynamically (re)position an element according to the bottom of the page using JS / Jquery? | <p><strong>the back story:</strong> i have a tab section on a page which when navigated through displays sections (divs) of varying height. </p>
<p><strong>the result,</strong> is that certain inputs (which are strangely positioned for reasons i can't change) on this page reposition themselves problematically. </p>
<p><strong>the proposed solution:</strong> as the page height changes, have these problem inputs repositioned according to the page bottom (from which their appropriate distances are always a constant). </p>
<p>what i'm thinking is that i need some js that does something like,</p>
<p><strong>page height change triggers input position from bottom to = x.</strong> </p>
<p>there are two inputs if that's at all relevant. :)</p>
<p>if only there was css for this (i know there is under normal circumstances, but trust me -- not in this case).</p>

129,321 | 129,322 | JS Include File From ASP.Net User Control | <p>This maybe a very basic question but for the life of me I cannot figure it out. So I have a user control that gets loaded on a page. Well, in this user control, I'm wanting to include a js file for some functions that are only specific to that user control. Inside this js file let's say I have a function called 'MyFunction'. In the onclick event of a div I'm wanting to call that function and I am unable to. Any help would be greatly appreciated.</p>
<p>I'm using the <code>ClientScriptManager</code> of the page object and I'm supposedly successfully including the file on the page using the following call:</p>
<pre><code>page.ClientScript.RegisterClientScriptInclude(scriptTitle,
page.ResolveUrl(scriptUrl))
</code></pre>
<p>Now, after this, I'm wondering, is there anything special I need to do to be able to call a function that's in the include file? like in my div:</p>
<pre><code><div class="someClass" onclick="MyFunction();">Click Me</div>
</code></pre>

}
public class App extends Application {
private MyHelper mHelper;
public void onCreate() {

mHelper.start();
}
}
</code></pre>
<p>We don't get any "app terminate" signal in Android though, so is the above keeping my app running forever in the background? There's no good place for me to know when to shut the thread down. </p>
<p>I wonder if the user pops the last activity from the stack (by hitting the back button), will my Application instance get destroyed even though the Thread is still possibly in a waiting state?</p>
<p>Thanks</p>
