Problem with prototype

[Gerry Vandermaesen]

Hi,

Consider the following code:

var Foo = Class.create();
Foo.prototype = {
initialize: function() {
this.bar = "Hello world";
},

load: function() {
new Ajax.Request("http://www.example.com/", { onSuccess: this.parse
});
},

parse: function(response) {
alert(this.bar);
}

}

foo = new Foo();
foo.load();

My problem is that although load() correctly executes the parse()
function on success, I seem to be in a different scope and all the
object's properties are undefined inside parse(). Anyone know how I
could call this function when the Ajax requests completes successfully,
while staying in the current scope?

Luckily I found the solution myself. In the "onSuccess" parameter, I
know pass "this.parse.bind(this)" and the "this" variable is bound to
the function.
