5,961,995 | 5,961,996 | jquery two clicks instead of one to execute code | <p>I found this javascript code, and that's exactly what I'm looking for. This is a Show/Hide code with slide effect.</p>

<p>Now, I wanted to add a code to show only one DIV at a time, closing opened DIV with slide effect. So, I add some code and it works how I want it to work. But the problem is, when one DIV is opened, and I click on another, new DIV, everything is working, but when I click on already visited DIV, I need two clicks, instead of one, to execute the code. I don't have a knowledge in js coding, so I'm asking here for your help. </p>
<p>Here is a code with my changes.</p>
<pre><code>$(document).ready(function() {

<p>That's the basic code. I tried doing this to the above mentioned code:</p>
<pre><code>while ($orders_status = tep_db_fetch_array($orders_status_query)) {
$status_id = $orders_status['orders_status_id'];
$status_name = $orders_status['orders_status_name'];
$status_group = $orders_status['orders_status_group'];
echo 'if (currentOption.val() == "' . $status_id . '") {
var optgroup = $("<optgroup/>");
optgroup.attr("label", "' . $status_group . '");
currentOption.wrapAll(optgroup);
}
';
}
</code></pre>
<p>What that did is basically created multiple Family of Doe. Instead I would like to somehow create only one Family of Doe and push Name and ID into it</p>

<p>is that in javascript when a primitive datatype is used in the context of the object, it is internally converted to an object. But this is just a <strong>temporary conversion</strong> in that the object will be removed from memory after it is used.</p>

So if I had: aaaaabbbbbcccccabckcka and im reading 5 at a time I would get, aaaaa, bbbbb,ccccc, abckc and ka. The code I am using is:</p>
<pre><code> status = is.read(bytes);
text = new String(bytes);
</code></pre>
<p>where bytes is: bytes = new byte[5], I am calling these two lines of code till status becomes -1, the problem I am facing is, the output is not what I have mentioned above, but I get this:</p>
<p>aaaaa, bbbbb, ccccc, abckc and kackc, notice the last segment 'kackc' is garbage, why is this happening ?</p>

function updatePrice(p) {
document.getElementById("price").value = p.replace(/[^0-9$.,]/g, '');

<p>The problem is that it removes characters after typing them so if you type A you see it for a fraction of a second before it disappears. Keydown is no good since it runs the script before the input actually changes.</p>

I am trying to get a GLSurfaceView with transparent pixels to render on top of the rest of my layout. So far I have not been succesful, the GLSurfaceView is displayed and renders properly, but pixels that are transparent show up completely black. My guess is that the default GLSurfaceView behaviour is the cause of my problem:</p>
<blockquote>
<p>The surface is Z ordered so that it is behind the window holding its SurfaceView; the SurfaceView punches a hole in its window to allow its surface to be displayed.</p>

<p>In the first example, the variable is not affected by the operation (and Eclipse gives no warning). I wonder why Eclipse has no message, and I don't understand why this assignment has no effect over the variable index <code>index = index--;</code></p>
