Setting an object's property value using object's method

Is There any way to set object property using object function? Eg:

var Object={
    init: function(){
        this.newParam=alert("ok");// This should alert ok while called     Object.newParam()
    }
}

Thanks in advance.

Try something like:

var Object={
        init: function(){
            return {
                newParam :function() {
                alert("ok");// This should alert ok while called Object.newParam()
             }
        }
        }
}
console.debug(Object.init().newParam());

Note that when init() is called it returns an object. You can use that object and invoke newParam function from that - Object.init().newParam()

No it wouldn't get called as per your expectation. It would get called during the time when the object is getting initialized. And obj.newParam would have the returned value of alert("ok"), i.e] undefined.

You have to rewrite your code like below to achieve what you want,

var obj = {
 init: function(){
  this.newParam= function() { 
    alert("ok");// This should alert ok while called Object.newParam()
  }
 }
}

Also using name Object for your variable is a riskier one when you are in the global context.
