You can add non static methods but you wouldn't be able to call them.</p>

Is there a generic way of getting the former thing done also in javascript?</p>
<p>Sample code would be smth like:</p>
<pre><code>function X() {};
X.prototype={
__getattr__:function(attrname) {

alert(x.lskdjoau); // produces message: "Value of attribute 'lskdjoau'"

<p>Now I have a function, which is actually a callback supplied to an ajax method. Now, how do I access the class members inside this function?</p>
<p><strong>---EDIT---</strong></p>
<p><strong>CASE I</strong></p>
<p>Suppose, here is the class I defined:</p>
<pre><code>var Person = Class.extend({
init: function(isDancing){
this.dancing = isDancing;
},
dance: function(){
return this.dancing;
}
});
</code></pre>
<p>And I use it like:</p>
<pre><code>var p = new Person(true);
$.ajax({url: url, success: p.dance});
</code></pre>
<p>Then, in the dance method, this.dancing wont work, because this wont point to the object p.</p>
<p><strong>CASE II:</strong></p>
<p>I am using knockoutjs (http://knockoutjs.com) for binding my UI to the objects. Suppose we have:</p>
<pre><code>var AppViewModel = Class.extend({
person: new Person()
});
</code></pre>
<p>and binding in html would be:</p>
<pre><code><button data-bind="click: person.dance">Dance</button>
</code></pre>
<p>in this case, the 'this' in dance would point to the object of AppViewModel, and not person.</p>
<p>The latter case is more important for me.</p>

4,507,120 | 4,507,121 | Storing a pointer to an object created in a method | <p>Using C++:</p>
<p>I currently have a method in which if an event occurs an object is created, and a pointer to that object is stored in a vector of pointers to objects of that class. However, since objects are destroyed once the local scope ends, does this mean that the pointer I stored to the object in the vector is now null or undefined? If so, are there any general ways to get around this - I'm assuming the best way would be to allocate on the heap.</p>
<p>I ask this because when I try to access the vector and do operations on the contents I am getting odd behavior, and I'm not sure if this could be the cause or if it's something totally unrelated.</p>

alert(myTextArea.value); // alerts the old value
myTextArea.value = "this is the new value of the textarea";

I succeeded changing the value of the textarea i'm writing in right now even though it has toolbar, but in all other sites especially blog sites the element value is changed but the text in the page stays the same.</p>
<p>I thought maybe the textarea is CKEditor but I don't know it's name so I can't use:</p>

2,419,761 | 2,419,762 | jQuery Toggle Bug | <p>I use the following code to toggle some stuff on a page. The problem is that if a user clicks too fast then more than one panel will open and stay on the page. I'm guessing this is because I'm using <code>click()</code> rather than <code>toggle()</code> but in order to get the full control of the animation I opted for the click function. Is there a way to get around this? Thanks.</p>
<p>EDIT: Another bug I have found is that upon page load the first panel fades off and then back in again because of the <code>.filter(':first').click();</code> at the end of the code, but this is used to get the active state on the first panel. Any alternatives?</p>
<pre><code>jQuery(document).ready(function()
{
var tabContainers = $('div.feature > div');
tabContainers.hide().filter(':first').show();
$('div.feature ul.feature-nav li a').click(function ()
{
var ref = this;
tabContainers.filter(':visible').fadeOut(500, function()
{
tabContainers.filter(ref.hash).fadeIn(500);

<p>In particular, there are static member variable initializations <code>int MyClass::myStaticVar = 0;</code> outside of any class definition at the top of the .cpp, and following that, there are static member function implementations <code>void MyClass::myStaticMethod() {...}</code>. Some <em>non-static</em> member functions are already being implemented in the .h, not the .cpp. So you can see there are some nuances here that I'd like to clarify.</p>

<p>This is naughty, but it will work if you only <code>#include</code> the .h once.
It breaks the convention and doesn't really work like a .h so it might
as well be named .doofus.</p>

1,432,052 | 1,432,053 | PHP Loop to search for string, execute if no match | <p>I am trying to search for multiple strings within a larger string and if none of them are a match, manipulate the original string. Here is the code:</p>
<pre><code>$searchthis = 'this is a string'
$arr = array('foo', 'bar');
foreach ($arr as &$value) {
if (strpos($searchthis, $value) !== false) {
break;
}
else{
$searchthis = $searchthis . ' addthis';
}
}
</code></pre>
<p>The problem is after searching the first string variable and not matching, the original searched string is manipulated before running the next test.</p>
<p>Any thoughts? Thanks in advance</p>
