Passing javascript object property

Question

How do you go about passing an objects properties in the follwoing situation:

ObjectTest = function()
{
 this.var1= "3"; 
 this.var2= "";
}

and the call

 ObjectTest .prototype.allFriends = function() {
 function bindEvents() {
 //pass var1 here
 }
 }

Is there a way to pass the ObjectTest properties without passing them as properties of the bindEvents(). I'd prefer a global solution if at all possible

Answer 1

You use the same code in the prototype of allFriends as you used in the constructor:

ObjectTest = function()
{
 this.var1= "3"; 
 this.var2= "";
}
ObjectTest.prototype.allFriends = function() {
 alert(this.var1);
}

Answer 2

It's the same: this.var1 - run this:

ObjectTest = function() {
 this.var1 = 3; 
 this.var2 = "";
};
ObjectTest.prototype.allFriends = function() {
 alert(this.var1);
};
x = new ObjectTest();
x.allFriends();

Answer 3

ObjectTest.prototype.allFriends = function() {
 do_smth_with(this.var1);
}

Beware, though, that you create a new ObjectTest by calling new ObjectTest(); without the new keyword it will not work.

EDIT: It will still work, because of the inner function will inherit the outer function's (allFriends) scope:

ObjectTest .prototype.allFriends = function() {
 function bindEvents() {
 console.log(this.var1);
 }
}

If it still doesn't work for you, use a reference to the parent's this:

ObjectTest .prototype.allFriends = function() {
 var parent = this;
 function bindEvents() {
 console.log(parent.var1);
 }
}
