Help! Javascript Gurus. Please Help Me. by David(m): 7:23am On Apr 16, 2013
So far, this group has really made me learn js fast. I really appreciate boss. Em. At it again. Is it possible to create a prototype of a prototype.
E.g
Array.prototype.style=
function(){};

style.prototype.textcolor= function(){
document.write("<p style='color:red;'>"+this+"</p>"wink;
}


style.prototype.align=
function(){
document.write("<p align='left'>"+this+"</p>"wink;
}

then using it, we will have something like:

people= ["mary","peter"];

people.style().textcolor().align();

And the result will be:
the names mary, peter in color red and aligned to the left.

Thus style is a prototype of an Array, while textcolor and align are prototypes of style.

please help. Thanks

Not Possible and frankly i don't see any use of this, you only extend a prototype of an Object and not an Object's function, in JavaScript Functions are First Class Objects they are treated as objects which is why they can expanded or have properties however that is when called using the new or if it is a Native Object the other function style belongs to Array thus just a simple function and not an object so it cannot be expanded, but if you need to work on an array and deference or chain always return the object Array and that way you can chain another array method, which is how jQuery works. here is one i did for you

//Extend the Array Prototype
Array.prototype.style=function(){
var a=[]; //create a dummy array
//walk over the array and style it pseudo-code
this.forEach(function(item,index,ar){
item+=item + " styled";
a.push(item); // populate array
});
return a; return the array
}
var a=["A","B","C"];
var b=a.style();
console.log( b );
