Add multiple [removed] events

Question

In my ASP.NET User Control I\'m adding some JavaScript to the window.onload event:

if (!Page.ClientScript.IsStartupScriptRegistered(this.GetType         


        

Answer 1

I had a similar problem today so I solved it having an index.js with the following:

window.onloadFuncs = [];

window.onload = function()
{
 for(var i in this.onloadFuncs)
 {
  this.onloadFuncs[i]();
 }
}

and in additional js files that i want to attach the onload event I just have to do this:

window.onloadFuncs.push(function(){
 // code here
});

I normally use jQuery though, but this time I was restricted to pure js wich forced to use my mind for a while!

Most of the "solutions" suggested are Microsoft-specific, or require bloated libraries. Here's one good way. This works with W3C-compliant browsers and with Microsoft IE.

if (window.addEventListener) // W3C standard
{
  window.addEventListener('load', myFunction, false); // NB **not** 'onload'
} 
else if (window.attachEvent) // Microsoft
{
  window.attachEvent('onload', myFunction);
}
