4,806,898 | 4,806,899 | Javascript variable problem | <p>I have a variable in javascript:</p>
<pre><code>var activeSearchButton = document.getElementById('<%=btnSearch.ClientID %>');

<p>I want to set it like this:</p>
<pre><code><asp:TextBox ID="WFTo" runat="server" onchange="activeSearchButton = document.getElementById('<%=btnWFSearch.ClientID %>');"></asp:TextBox>

<p>When I am trying to use the varible in javascript function, it is null. And the source shows:</p>
<pre><code>onchange="activeSearchButton = document.getElementById('&lt;%=btnSearch.ClientID %>');"
</code></pre>
<p>I noticed '& lt;' instead of "<". Is this the reason of my problem? Why does this happen? Or maybe there is another reason?</p>

3,675,761 | 3,675,762 | base64 encode audio file and send as a String then decode the String | <p>I have been stuck on this issue for a few hours now trying to get it working. Basically what I am trying to do is the following. Base64 encode an audio file picked up from an sdcard on an Android device, Base64 encode it, convert it into a String and then decode the String using Base64 again and save the file back to sdcard. It all sounds fairly simple and works great when doing it using a text file. For example if I create a simple text file, call it dave.text and inject some text it in say "Hello Dave" or something similar it works great, but fails when I try doing the same with a binary file, audio in this example. Here's the code that I am using.</p>
<pre><code>File file = new File(Environment.getExternalStorageDirectory() + "/hello-4.wav");
byte[] FileBytes = FileUtils.readFileToByteArray(file);
byte[] encodedBytes = Base64.encode(FileBytes, 0);
String encodedString = new String(encodedBytes);
Utilities.log("~~~~~~~~ Encoded: ", new String(encodedString));
byte[] decodedBytes = Base64.decode(encodedString, 0);
String decodedString = new String(decodedBytes);
Utilities.log("~~~~~~~~ Decoded: ", new String(decodedString));
try {
File file2 = new File(Environment.getExternalStorageDirectory() + "/hello-5.wav");
FileOutputStream os = new FileOutputStream(file2, true);
os.write(decodedString.getBytes());
os.flush();
os.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
</code></pre>
<p>At this point if I try to save the file, it becomes corrupted. The audio file hello-5.wav is larger in size then the original and it doesn't play.</p>
<p>Any ideas what I am doing wrong here? If I try to save decodedBytes using os.write(decodedBytes) it works but not when converted to a String and getBytes() is used.</p>
<p>Any ideas? Thank You!</p>

<p>I've tried using a binary search method to make this more efficient, but what I have so far brings up a slow script dialog in my browser:</p>
<pre><code>function constrain(text, ideal_width){
var temp = $('.temp_item');
temp.html(text);
var item_width = temp.width();
var ideal = parseInt(ideal_width);
var lower = 0;
var original = text.length;
var higher = text.length;
while (item_width != ideal) {
var mid = parseInt((lower + higher) / 2);
var smaller_text = text.substr(0, mid);
temp.html(smaller_text);
item_width = temp.width();
if (item_width > ideal) {
// make smaller to the mean of "lower" and this
higher = mid - 1;
} else {
// make larger to the mean of "higher" and this
lower = mid + 1;
}
}
var final_length = smaller_text.length;
if (final_length != original) {
return (smaller_text + '&hellip;');
} else {
return text;
}
}
</code></pre>
<p>Does anyone have an idea of what I should be doing to make this function as efficient as possible?</p>

Now I'd like to sense a double-click on the down button and have that reduce the border immediately to 0. The problem I'm havng is that if you try to down click the border one px at a time, you can't help but trigger the double-click, even if you click the down button no faster than about once per second. It seems that I should have to do both clicks in less than about 250ms to trigger the double-click. Does anyone know what's going on?</p>
<p>Thanks.</p>

<p>Even Android supports Native code applications, the main development tool is Java. But why? I mean, isn't it too slow to interpret code on a mobile device? when introducing Froyo, Google said that new JIT compiler can achieve 2-5 times faster applications. This means, that using Java over native code is 2-x times slower.</p>
<p>Yes, I know that using managed code applications is safer in terms of system stability, since virtual machine has better control of program, but still, this performance drop is huge, and I don´t see any point why to use it. Please tell me some good reason. Thanks.</p>

<p><strong>Problem</strong></p>
<p>I need to retrieve all child-elements where the <strong>attribute-name</strong> (note: <strong>not</strong> the <em>attribute-value</em>) starts with a given string.</p>
<p>So if I have:</p>
<pre><code><a data-prefix-age="22">22</a>
<a data-prefix-weight="82">82</a>
<a href="#">meh</a>

<p>My query would return a collection of two elements, which would be the first two with the <strong>data-prefix-</strong>-prefix</p>
<p>Any ideas on how to write up this query?</p>
<p>I was going for something like:</p>
<pre><code>$(document).find("[data-prefix-*]")

<p>But of course that is not valid</p>
<p>Hopefully one of you has a more keen eye on how to resolve this.</p>
<p><strong>Solution</strong></p>
<p>(See accepted code example below)</p>
<p>There is <em>apparently</em> <strong>no direct way to query on partial attribute names</strong>. What you should do instead (this is just one possible solution) is </p>
<ol>
<li>select the smallest possible collection of elements you can</li>
<li>iterate over them</li>
<li>and then for each element iterate over the attributes of the element</li>
<li>When you find a hit, add it to a collection</li>
<li>then leave the loop and move on to the next element to be checked. </li>
</ol>
<p>You should end up with an array containing the elements you need.</p>

The javascript code is based on jQuery.</p>
<p>My question is how to do this to be safe and optimized, cause I don't want to break certain users website.</p>
<p>The thing I'm looking for so far( you can update if you think I need to face other problems):</p>
<ol>
<li>what happens when the user already has jquery loaded on their page? should I load my jquery library using different namespace or should I use his jquery library.</li>
<li>in case I can use his jquery library, I think I'll need to check to see if the versions corespond, but again is this safe?</li>
<li>in case I want to use his jquery library, how do I check if he has jquery loaded and if he has the right version</li>
<li>this is related to 3. what happen if he changes his jquery library that doesn't correspond with the library I think it will be, leading to a bad result.</li>
</ol>
<p>Looking for your answers.

845,099 | 845,100 | Shift focus with arrow keys in JavaScript | <p>I want to be able to navigate through all the focusable elements on my webpage with the arrow key. So when the down-key is pressed the focus should shift to the focusable element beneath the current focussed element. You get the idea for the other arrow keys, when there is not a focusable element to shift to, the focus should remain the same.</p>
<p>This is what I got so far:</p>
<pre><code>$(document).keydown(function(e){
if (e.keyCode == 37) { //left
var offset = $("*:focus").offset();
var allElements = $("#container").find('a[href], area[href], input:not([disabled]), select:not([disabled]), textarea:not([disabled]), button:not([disabled]), iframe, object, embed, *[tabindex], *[contenteditable]');
var arr = jQuery.makeArray(allElements);
var topLeft = offset.left
var minus = topLeft;
var currentElement = $("*:focus");
for(var i = 0; i < arr.length; i++)
{
if ( (arr[i].offset().left < offset.left) // This doesn't work for some reason
&& ((offset.left - arr[i].offset().left) < minus))
{
currentElement = arr[i];
minus = offset.left - arr[i].offset().left;
topLeft = arr[i].offset().left;
}
currentElement.focus();
}
alert( "left pressed" );
return false;
}
// Other Keys
</code></pre>
<p>});</p>
<p>the idea was to get all the focus-able elements and than pick select the one that is suited for the arrow and shift focus. </p>
<p>I'm not able to get this code to work (it contains a error) and I'm not completly sure it will even work.</p>

3,742,076 | 3,742,077 | perform function after x number of calls with setInterval | <p>In <a href="http://stackoverflow.com/a/2956980/1252748">this article</a>, the following function is given to perform an operation <em>x</em> times with setInterval()</p>
<pre><code>setIntervalX(function () {
animateColor();
//or something
}, 3000, 4);
function setIntervalX(callback, delay, repetitions) {
var x = 0;
var intervalID = window.setInterval(function () {
callback();
if (++x === repetitions) {
window.clearInterval(intervalID);
}
}, delay);
}
</code></pre>
<p>what does the callback() do here? I'm trying to do a function after the specified number of repetitions is complete. but this</p>
<pre><code>setIntervalX(function () {
animateColor();
}, 3000, 4, function(){
completeFunction();
});
</code></pre>
<p>does not work. Perhaps that syntax is very wrong. I was under the impression that using jquery, you could string together functions like that..</p>
<p>Much grateful for any insight. Thanks!</p>
