Question

I’m refactoring about 600 lines of javascript into the module pattern. Here is a start from previous post:
I undertand the concept of anonymous methods…and sefl-executing….but not the scoping concepts…i.e. what global and window do.

window.onload=initialize_page;

(function (global) {  
 global['test'] = 'test'; 

function initialize_page()
  {
  /* fill  here */
  }

})(window); 

Can I put window.onload=initialize_page into my module pattern? Or does it need to be put outside of it? Can someone explain how the access works?

EDIT 1: per Answer

(function () {  

addEventListener('load', initialize_page);

function initialize_page()
  {
  alert ("hi");
  }

})(); 

Answer 1

It is a global. Don’t touch it like that, you’ll overwrite any other code that tries to assign load handlers.

Use addEventListener (or attachEvent for old IE) instead. There are plenty of libraries that abstract the functionality.
