Override the window.onload javascript function

1. Creates a blank function
2. Checks onload for a function.
2a. Sets the originial onload function as temp
3. calls the new function initMap() before the originial temp onload function.

Pretty cool!

Code:

1
2
3
4
5
6
7

var temp=function(){ return 1;};
if( window.onload )
{
      //override "placeholder" with whatever already exists in onload
     temp = window.onload;
}
window.onload=function(){ TheFunctionYouWantToCall(); temp();};
