1,975,678 | 1,975,679 | Jquery: syntax for inserting a function | <p>I'm trying to integrate an animation by using the bezier path plug-in and I can't seem to implement it right.</p>
<p>Stripped down, here's what I have:</p>
<pre><code> $('#next2btn').live('click', function(){
$(this).attr('id','next3btn');
$('#content2').show(300, function() {
$('#account').fadeTo(500,1.0)
var arc_params = {
center: [278,120],
radius: 186,
start: -90,
end: 90,
dir: -1
};
});
$("#account").animate({path : new $.path.arc(arc_params)},1000);
});
</code></pre>
<p>So, I'm trying to add this piece of code into what I have:</p>
<pre><code> var arc_params = {
center: [278,120],
radius: 186,
start: -90,
end: 90,
dir: -1
};
});
$("#account").animate({path : new $.path.arc(arc_params)},1000)
</code></pre>
<p>which works on its own as does the other.</p>
<p>I'm thinking it's something about declaring that variable and where I do that.</p>
<p>I'm essentially chaining a few different animations/actions upon a button click.</p>
<p>Thanks for any insight-

<p>It needs to be able to perform well with <em>lots</em> of nodes. Perhaps 1,000 sibling nodes. It needs to be able to draw to a usable state within 2 or 3 seconds with 1,000 nodes.

1,709,241 | 1,709,242 | How do I change the View's visibility based on another View's animation in a custom layout? | <p>I created a custom RelativeLayout called WheelLayout which contains two ImageViews. The first View, WheelView, is a custom View that calls RotateAnimation a couple times. </p>
<p>WheelView has a custom interface called WheelListener.</p>
<pre><code> public interface WheelListener {
public void wheelStarted();
public void wheelStoppedOnSlice(int sliceNum);
}
</code></pre>
<p>In WheelView, I implement Animation.AnimationListener as follows:</p>
<pre><code>@Override
public void onAnimationStart(Animation animation) {
mListener.wheelStarted();
}
@Override
public void onAnimationEnd(Animation animation) {
mListener.wheelStoppedOnSlice(mCurrentSlice);
}
@Override
public void onAnimationRepeat(Animation animation) {
}
</code></pre>
<p>Where mListener is a WheelListener.</p>
<p>WheelLayout implements WheelListener like so:</p>
<pre><code>@Override
public void wheelStarted() {
mSliceImage.setVisibility(View.GONE);
}
@Override
public void wheelStoppedOnSlice(int sliceNum) {
mSliceImage.setBackgroundResource(mSlices[sliceNum]);
mSliceImage.setVisibility(View.VISIBLE);
}
</code></pre>
<p>When WheelView animates, I expect to see mSliceImage disappear and WheelView to continue its animation to completion. Instead, neither occurs. My WheelView does not animate and mSliceImage does not disappear.</p>
<p>However, after the animation would finish, I <em>do</em> see mSliceImage change its background resource.</p>
<p>I also tried the same thing where mSliceImage was <em>not</em> a child of custom layout and it worked perfectly.</p>
<p>Does anyone have any ideas?</p>

<p>However, when rotating from landscape to landscape (through 180 degrees) onConfigurationChanged() is not called.</p>

<a href="http://stackoverflow.com/questions/400212/how-to-copy-to-the-clipboard-in-javascript">How to copy to the clipboard in JavaScript?</a> </p>
</blockquote>
<p>I am trying to implement a cross-browser Javascript copy button, but am unable to use Flash, unfortunately, so I've come up with a different solution for Chrome/Firefox, etc.</p>
<p>The issue I'm having is the syntax for actually calling the function: it seems that IE doesn't like if I have an apostrophe in the argument, and nothing else likes it if I <em>don't</em>. For example, the HTML:</p>
<pre><code><button onclick="copy(el)"/>Copy</button>
</code></pre>
<p>Works fine with the IE-only Javascript:</p>
<pre><code>textRange = document.body.createTextRange();
textRange.moveToElementText(el);
textRange.execCommand("Copy");
</code></pre>
<p>But when I try to do the following for Chrome/Firefox, I get a Type Mismatch error in Firebug:</p>
<pre><code>document.getElementById(el).innerHTML;
</code></pre>
<p>If I add apostrophes around the argument in the original function call (onclick="copy('el')"), it works fine in Chrome/Firefox, but IE gives a type mismatch error.</p>
<p>How can I resolve this so that I can call the function—preferably with apostrophes around the arguement—but it will work in all browsers? Thanks.</p>

<p>I also have another web project which is build with VS2008/2.0. IIS setting - ASP version 2.0 is selected and all pages are assigned to run with 2.0* dlls. Lets say project Y</p>
<p>Now the problem seem to be when I hit project x, sometimes it throws errors like:</p>
<pre><code>error BC30456: 'Initialize Culture' is not a member of ASP
</code></pre>
<p>During troubleshooting this issue, I browsed through 2.0 Temporary ASP.Net files <code>"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\"</code> and found temp files generated for project X. (HUH?)</p>
<p>How/why 1.1 project gets compiled in 2.0 only when it errors out.( or we could put it this way that it errors out every time it gets compiled in 2.0 which it is not supposed to)</p>
<p>I'm confused as to why this is happening when project X has nothing to do with .net 2.0.</p>

<p>IIS version 6.0</p>
<p>I forgot to mention that project X works 95 percent of the time without any errors under 1.1. This error throws randomly which we could not recreate. The time the project error out is at the same time it gets compiled with 2.0</p>

<p>I'll ask the question by example:</p>

<p>I've written the code "$('html :hidden').length;"</p>
<p>At this stage I did not know the output. To know if I had written the right code I then wrote:</p>
<p>"var hidden = $('html :hidden').length;</p>
<p>$('h3').html(hidden);"</p>
<p>The h3 changed to "8" which told me that there are 8 hidden elements on the page. Changing the h3 element to find out that I had done something correctly seems a bit crude. Is there a conventional way to know if you have either selected an object correctly or to know a value without actually writing on the html doc?</p>

I wan't the method to also have an integer parameter which makes it perform this n times. I want to be able to call like <code>changeButtons(5);</code> and it turns button x background blue for 1 second then waits 1 second five times.</p>
<p>So practically I'm trying to make a "main" thread which runs during the game and inside that thread I'm going to run this method whenever certain conditions are true (a thread which calls a thread).</p>
<p>So I have 2 questions. The first one is "Is this possible? " and If so can someone show me how to do it (not all of it of course but help me get started at least)? Especially I want to know if I can change a buttons background color in a thread and if so can someone show me how to write/get me started that thread? </p>
<p>The second question is a follow-up, if you can do this, can you have a like a <code>boolean b</code> which turns to true if someone presses a button and the thread can "notice" that change? For example, if the thread is running and Obama presses button x and b turns "true" in the method <code>OnClick(View v)</code> can I, inside my main thead have an <code>if(b == true){Obama.moon();}</code> and Obama will moon? </p>

948,532 | 948,533 | Split() method in Java for multi-dimensional array | <p>I have a two dimensional array. The assignment is to accept row and columns numbers from user and if user wants to enter numeric data row by row (or column by column) he has to do that with comma. Such as, 3x3 will be:</p>
<p>1,2,4</p>
<p>2,5,3</p>
<p>5,3,2 </p>
<p>So the the first row elements will be [0,0]=1 [0,1]=2 [0,2]=3, second row [1,0]=2 [1,1]=5 [1,2]=3, etc.

5,046,051 | 5,046,052 | How to Make Web Service Call Without Making the GUI Unresponsive | <p>I have a <code>UISearchBar</code> and <code>UISearchDisplayController</code>. When the user writes text in it inside <code>searchBar:textDidChange:</code> I make a web-service call to filter my TableView. The problem is that the GUI get unresponsive until I get the result from the web-service. I've tried to solve it using <code>[self performSelector:@selector(callWebService:) withObject:searchText];</code>, but it's still unresponsive. </p>
<p>EDIT: Following Flink advice, I changed <code>performSelector</code> to <code>performSelectorInBackground</code>, but now the tableView doesn't filter correctly, it only show 'No Results'.
even <code>tableView:numberOfRowsInSection:</code> isn't get called.</p>
<p>EDIT Again: The reason I got 'No Results' was due to not calling <code>reloadData</code> on the correct tableView. <code>UISearchDisplayController</code> has a property named <code>searchResultsTableView</code>. So in the end what I used was <code>[self.searchDisplayController.searchResultsTableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:false];</code> and now it works fine.</p>
<p>It should be noted that although I chose the <code>performSelectorInBackground</code>, I probably should have tried to use <code>sendAsynchronousRequest</code> method on <code>NSURLConnection</code> - See AliSoftware's answer.</p>

4,936,446 | 4,936,447 | How to animate views? | <p>I'm working on a game that in some ways is similar to Tetris (imagine a 2D array of colored squares that sometimes move around)</p>
<p>I am trying to animate the individual squares so they will smoothly slide down from coordinate to the next. Since I wanted to use Android's built-in tweening feature, the animation has to apply to the whole View (rather than parts of it). This doesn't work well for me because I only want some of the colored squares to slide down, and the rest of them to stay still.</p>
<p>The (theoretical) solution I came up with to resolve this is to make 2 Views, layered directly on top of each other. The top view is for animating squares when they need to move, and the bottom layer is for the static squares. The animation-layer is transparent until I am ready to animate something. I then simply turn on the colored square in the animation-layer, tween it to the new location, and turn it back off when done. In the same time span, the static-layer just turns squares on and off at the right time to make the whole thing look seamless to the end user.</p>
<p>The proposed solution is just a theory, since I haven't been able to make it work correctly yet. Since I have been having trouble, I was wondering if this is even the best way to solve the problem? Perhaps there is a more elegant solution that I am over looking? Anyone know of a better way?</p>

<p>I'm getting better, but one of the things I still find quite annoying about the usual development model is that I really have no idea what the SDK is really doing behind the scenes to make the app "work" because Apple <em>protects</em> me from this.

Where that code is and what it does and how it works are not obvious (to me).</p>
<p>So I'm wondering, is it possible to create an iPhone app entirely programmatically? That is, have execution start in some main method, which will then programmatically create any views, register event listeners, etc. And if yes, what are some good resources for something like this?</p>
