Is there a way to do embedded 'classes' in &#106avascript? (JScript, JS, whatever's the correct name for it) I've just recently figured out how to do 'classes' in &#106avascript, which is kind of odd, and now I'm wondering how to make embedded classes. My attempt: <div class="source"><pre> function Class() { this.Func=function() ... //Priviledged Class.Func=function() ... //Static Class.Sub=function() { //Static... Class.Sub.Func=function() { /* Error here */ } } } </pre></div> I'm using Firefox 2.0.0.1

The term is &#106avascript or JS when it's an abbreviation. JScript is something else :)

Let me give you an example.

/** * A class in JavaScript is just a function. */function MyClass(){}/** * A public var with value 12 */MyClass.prototype.MyVar = 12;/** * A public function */MyClass.prototype.MyFunction = function(){	alert('Hi there!');};// Now create the inner class/** * The second class! */MyClass.MySecondClass = function(){}/** * A public var with value 891273 */MyClass.MySecondClass.prototype.MyVar = 891273;

(Edit: http://www.sitepoint.com/article/oriented-programming-1 is pretty good intro to OOP in &#106avascript, <a href="http://dean.edwards.name/weblog/2006/03/base/">http://dean.edwards.name/weblog/2006/03/base/</a> for 'real' OOP!) (Edit 2: Create actual url's of my first edit ;)) (Edit 3: I can't work with BB code, hope this is my last edit :P)

Thanks for the info!

... Figured out what I was doing wrong in my example. I was embedding the sub-class, therefore its type would be instantiated until I called the constructor of the containing class. I forgot to include where I called the function "Class.Sub.Func". Yeah...
Sorry to say, but I hate &#106avascript. *Sobs and crawls slowly back to C++*
