Hi all.

I'm probably doing something stupid but I can't get started with OO in Javascript. (It's been a while.) Nothing is working properly. My latest mistake is:

Code:

var Blob = Class.create({
   initialize: function(text) {
      this.text = text;
      this.count = 0;
   }
});

I get "Uncaught ReferenceError: 'Class' is not defined" in the Extensions debugger, just under the "var Blob" line. Do I need to include something?

Before that I tried:

Code:

function Blob(text) {
   this.text = text;
   this.count = 0;
}

Blob.prototype = { }

which seemed to work, until I noticed that member "this" pointed at the DomWindow. Not what I need at all.

Can someone give me a working example of a class, since I appear to be too thick to work it out myself?

I'm running chromium-browser 8.0.561.0 (63476) Ubuntu 10.04, if that sheds any light on my problem.

Thanks.

close ... but a miss ;-)

Code:

function Foo()
{
    this.x = 1;
    this.y = 2;
}
 
obj = new Foo;
console.log(obj.x);

You can use .prototype to define additional properties and even some kind of inheritance/hierarchy of objects.
