Javascript Object - Syntax Help

[SirCodesALot]

Can someone help me with this syntax, I have the following javascript
object:

function foo()
{
this.myFooVar = 0;
this.doThis = function (){
var ao = new AnotherObject();
ao.onReadyStateChange = function(){
if (this.myFooVar == 0) <----------- Here is the
problem
{
// do this
}
}
}
}

How do I refer to the "this.myFooVar" from the foo object when
defining the sub-sub function for on readyStateChange? Did i need to
use a keyword like parent?

Thanks in advance for your help.

just use a closure:

function foo()
{
this.myFooVar = 0;
var myFoo = this; // save the this object
this.doThis = function (){
var ao = new AnotherObject();
ao.onReadyStateChange = function(){
if (myFoo.myFooVar == 0) // access it here
{
// do this
}
}
}
}
