access parent object in javascript
You can't.
There is no upwards relationship in JavaScript.
Take for example:
var foo = {
bar: [1,2,3]
}
var baz = {};
baz.bar = foo.bar;
The single array object now has two "parents".
What you could do is something like:
var User = function User(name) {
this.name = name;
};
User.prototype = {};
User.prototype.ShowGreetings = function () {
alert(this.name);
};
var user = new User('For Example');
user.ShowGreetings();
var user = {
Name: "Some user",
Methods: {
ShowGreetings: function() {
alert(this.Parent.Name); // "this" is the Methods object
},
GetUserName: function() { }
},
Init: function() {
this.Methods.Parent = this; // it allows the Methods object to know who its Parent is
delete this.Init; // if you don't need the Init method anymore after the you instanced the object you can remove it
return this; // it gives back the object itself to instance it
}
}.Init();
