Resolved Nested Methods and Properties in JavaScript

[jschrend]

Hi all! I'm pretty new to JavaScript and completely new to this forum. I'm James.

Well uh, I'm not sure how to...

I wanted to make something like this using javascript...

myObject.someMethod('something').anotherProperty

much like the

document.getElementById('someId').style.morestuff

But the thing is, I've been around every DOM whatnot I can find, I just can't seem to make it work.

I kinda need it to make my own DOM for some API i'm writing. So I can write like...

function someGreatAPI(){
     this.property1='';
     this.property2='';
     //...
     this.method1 = function(var1){            //this should make my firstMethod
           this.nestedProperty = 0;
           this.nestedMethod = someFunction;  //firstMethods nested method

     }
}

//so I can use it like...

var obj = new someGreatAPI();
obj.method1(10).nestedMethod();

It has to be possible, it's possible with document.getelementbyid, right? it has to be.

Thanks in advance.

The reason it works with document.getElementById is because getElementById returns an HTML element.

obj.method1 doesn't return anything, so obj.method1(10).nestedMethod() is resolved as obj.(undefined).nestedMethod()

Since method1 is a constructor, you would do it like this:

var testObj=new obj.method1(10);
testObj.nestedMethod();

Edit - to make it work in exactly the same way you would have to do something like this:

function someGreatAPI(){
	this.property1='';
	this.property2='';
	//...
	
	this.method1 = function(var1) {
		this.nestedProperty = 0;
		this.nestedMethod = function() {
			alert(var1);
		};
	}
	
	this.createNewM1=function(n) {
		return new this.method1(n);
	}
}

var obj = new someGreatAPI();

obj.createNewM1(10).nestedMethod();

It has to return an object, I see. Thanks man, that's exactly what I needed.
