Passing Parameters on Javascript File

I’ve been amazed by these codes.. passing parameters on javascript file.. so I decided to share how this thing works…

// test javascript

/*

<script src=”js/jquery.js” type=”text/javascript”></script>
<script id=”jsf1″ src=”js_test.js?xerxis,alvar” type=”text/javascript”></script>

*/

Javascript Design Pattern (Prototype)

I dont know what to call this one, ‘coz others call it Prototype and some call it custom objects.

The idea is the same with the Module pattern, to keep private objects and public object;

var Student = function() {}(); << — Object constructor

or

var Student = {}; <<<— this comes more handy ^_^

Javascript Design Pattern (Module)

Ok this one is another design pattern, the goal is to keep private objects from public objects. Only functions inside the function block can access private variables and methods.

Let us improve our previous  (singleton ) pattern

Javascript Design Pattern (Singleton)

hi I’ve been reading a lot about design patterns, I just want to share stuff about design patterns that at first I was bored reading and analysing things up.

This is the Singleton javascript design pattern :

Goal :

Student    <<– this will be the object
Notebook  <<– this is one of our object’s property
Name      <<– Another property of our object.

Self-Invoking Function (function(){..stament..})();

As I was continuing exploring Javascript Design Pattern, I bumped in to this topic. A weird looking code that for a beginner, it will be a pain in the 4$$.
