Running javascript after window.onload without breaking Sharepoint

If you're anything like me and are working with a lot of Javascript within Sharepoint. You will eventually need to run a script after the page loads. So you could add defer="defer" to your script tag, which sometimes works and sometimes doesn't.

You might be tempted to window.onload = someFunction(). But this will break the way Sharepoint load's it's pages. As Sharepoint also needs to do a lot of things after the page loads.

So the solution is:
window.attachEvent("onload", someFunction);

So instead of overriding the onload event. You are now adding an event to the queue. Simply replace the "someFunction" bit with your function name.

Embedding a resource in your ASP.NET 2.0 assembly

While developing a web part for Sharepoint I came across an issue where I needed to have Javascript manipulate elements in the web part. I searched around for the best way to include my Javascript file as part of my Sharepoint solution and came across many articles but I couldn't get their methods to work until I came across this one:
http://www.codeproject.com/KB/aspnet/MyWebResourceProj.aspx

I'm not sure why but "Page.ClientScript.GetWebResourceUrl" seems to work for me but "Page.ClientScript.RegisterClientScriptResource" as per this article doesn't.

Dynamically set the onclick attribute of a html element using Javascript

I've been trying to dynamically set the onlick attribute of a span element in Javascript.
I tried a couple of things including:
var newNavNode = document.createElement("span");
newNavNode.onclick = "horizontalNavClick('"+nodeValue+"');" ;

But this wasn't working as a reference to the function was needed and not a string.

I googled and found this post: http://codingforums.com/archive/index.php?t-55356.html

And modified my script to:
var newNavNode = document.createElement("span");
newNavNode.onclick = new Function("horizontalNavClick('"+nodeValue+"')");

This worked like a charm. Thanks Willy Duitt!

Happy scripting everyone!
