Unfortunately, obviously since this is inside a void method, 'this' does not work.</p>
<p>How do I deal with this?
Is there a way to create a local ImageObserver variable?
I dont need to use it really.</p>

graphics.drawImage(bi,d.width/2+10,110,128,128,iob);

2,167,547 | 2,167,548 | jquery empty function and event handlers | <p>In the jquery documentation of the "empty" function (http://api.jquery.com/empty/) there is the following statement:</p>
<pre><code>"To avoid memory leaks, jQuery removes other constructs such as data and event handlers
from the child elements before removing the elements themselves."
</code></pre>
<p>The text says: "... jQuery removes event handlers from the !C H I L D! elements ...". But I want the event handlers also removed from the div tag ($("#mydiv").empty). I know that there is the function "remove", but my intention is to not remove the div tag. What is the best way to get this done?</p>
<p>The other thing is:<br>
When they say "remove event handlers". Do they only remove constructs made with "bind" or do they also remove constructs made with "delegate"?</p>

<pre><code>class MyClass(object):

5,441,864 | 5,441,865 | reading the checkbox status in IE using Javascript | <p>I have some javascript that on page load reads a group of check boxes checking their checked status. If the checkbox is checked then a value is added to an array which is later used.</p>
<pre><code>var _chkBoxes = document.getElementsByName("chkProduct");
var _chkBoxesLen = _chkBoxes.length;
var _chkArray = [];
for (var i = 0; i < _chkBoxesLen; i++) {
if (_chkBoxes[i].checked === true) {
_chkArray.push(_chkBoxes[i].id.split("-")[1]);
console.log(_chkArray);

<p>This works fine for all browsers when the page is freshly loaded.</p>
<p>However in IE if a user ticks some boxes, navigates to another page then pushes the back button then this work does not recognise that checkboxes have been previously checked, even though on the page they are.</p>

1,719,312 | 1,719,313 | Exceptions in database model, how do I handle it? | <p>I am creating a model for a small PHP application. This will utilize PDO to communicate with a MySQL-server. I have understood that the recommended error mode is the one which throws exceptions, as this allows for graceful error handling. But I don't understand how I should handle these exceptions?</p>
<p>Technically, it is easy, but let me give you an example:</p>
<pre><code>class Model()
{
private $host = "localhost",
$user = "",
$pass = "",
$DBH;
function __construct()
{
try
{
$DBH = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
$DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch(PDOException $e)
{
error_log($e->getMessage());
}
}
}
</code></pre>
<p>If I create an object Model in my controller, and it fails, I have no way of handling this in my controller, right? Or what happens when I create that object, "new Model" returns false? </p>
<p>Excuse me for being a newbie, but I want to be able to handle any exceptions also from other functions in the model. How should I go about this? I need to be able to know if something went wrong in my controller and be able to do the appropriate thing there.</p>

101,010 | 101,011 | jQuery call on a <div> tag (or any HTML element) - is looping implied? | <p>I'm learning jQuery and had a question about a method call on an HTML element. In this case it's a <code><div></code> tag.</p>

<pre><code><script type="text/javascript">
$(function(){
$('.someClass').myMethod({
value1: 'sometext',
value2: 'someothertext'
});
});
</script>

</div>
</div>

5,656,197 | 5,656,198 | Disable Home Button and Have Application Full Screen with No Title (no status bar, no title) in Android Froyo | <p>First off, yes I know that its not the intended behavior of the OS to disable the home button, but the application I am creating is for use on a collection of devices for use inside of a closed organization only and not public consumption. Secondly, I know that there are many similar questions and spotty answers everywhere, but no solution has been presented as of yet, so I felt it prudent (albeit somewhat self serving) to put the question out there one more time properly.</p>
<p>I am trying to simply create a splash screen that is also a remote network lock screen. When the device is remotely told to do so it will end the activity and the user can begin to use the device.</p>
<p>In the manifest this is set:</p>
<pre><code><activity android:name=".ActivityOne" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
</code></pre>
<p>In the Activity:</p>
<pre><code>@Override
public void onAttachedToWindow()
{
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
</code></pre>
<p>Combined these stop the home button, but seem to allow the status bar to remain visible. There are several obvious reasons why I would not want the status bar visible, but most importantly once a user 'pulls down' on the status bar to see the notifications area the home button becomes usable again and the whole exercise is circumvented.</p>
<p>I am primarily looking for an answer to this, condoned or a hack via code. If there is not a direct modification that can be done to the code set above, I would certainly appreciate and accept an answer that properly describes (preferably with code samples) any alternative logic that achieves the same goal. The alternatives can be to modify some system files or other lower level techniques.</p>
<p>As a final note, please know that we have SU / Root access for all of the devices.</p>

4,537,287 | 4,537,288 | Create Globally Unique ID in JavaScript | <p>I have a script that, when a user loads, creates a unique id. Which is then saved in <code>localStorage</code> and used for tracking transactions. Sort of like using a cookie, except since the browser is generating the unique id there might be collisions when sent to the server. Right now I'm using the following code:</p>
<pre class="lang-js prettyprint-override"><code>function genID() {
return Math.random().toString(36).substr(2)
+ Math.random().toString(36).substr(2)
+ Math.random().toString(36).substr(2)
+ Math.random().toString(36).substr(2);
}
</code></pre>
<p>I realize this is a super basic implementation, and want some feedback on better ways to create a "more random" id that will prevent collisions on the server. Any ideas?</p>

213,963 | 213,964 | primitives as function arguments in javascript | <p>I'm learning JS here, and have a question regarding primitive values when passed in as arguments. Say I have a simple function: </p>
<pre><code>var first= 5;
var second= 6;
function func(){
first+=second;
}
func();
alert(first);//outputs 11
</code></pre>
<p>So in this case the value of first becomes 11.. But if I try it by passing in first as an argument to the function, first remains 5..</p>
<pre><code>var first= 5;
var second= 6;
function func(first){
first+=second;
}
func(first);
alert(first);//outputs 5

<p>I would like to automate it, hence take inputs from user into a txt file and need to pass each row of data as parameter to the existing program.</p>
<p>For eg: the first row of data in the .txt file will be like : 10 20 30 2013 10 20 40 2013..</p>
<p>Now each number is a parameter to the program. eg. param1-10 param2-20 and so on...</p>
<p>Is this achievable? Please advise. also please let me know if you need more details on the same.</p>

1,892,918 | 1,892,919 | Javascript new object reference | <p>what is the correct syntax to create a new instance of the object as opposed to a pointer to the original? Here is my example:</p>
<pre><code>var oItem = { element: null, colIndex: 0 };
var oInputs = { Qty: oItem, Tare: oItem, Rate: oItem, Total: oItem };
for (var oTitle in oInputs) {
oInputs[oTitle].element = ...
</code></pre>
<p>when I set the value of <code>oInputs[oTitle].element</code> for any <code>oTitle</code> it sets the value of them all. I know that javascript passes objects by reference, so I am assuming it's because they are all referring to the same object. I tried this but it is obviously wrong.</p>
