first of all, validate your HTML (http://validator.w3.org)

further, this code seems terribly outdated (so you might read a Javascript tutorial to get up to date)

and I don’t understand what the code should do… you try to copy code around when you’re probably better off just executing the function.

PS. please don’t hijack someone other’s thread if you have an unrelated question, just open a new thread.

and… welcome at bytes.com

If you want to add JavaScript code to the head, try something like this:

Expand|Select|Wrap|Line Numbers

 var script = document.createElement("script");

var text = document.createTextNode("code here");

script.appendChild(text);

document.getElementsByTagName("head")[0].appendChild(script);

@tomeshjain
the bold marked XHTML code will cause an error. the bold marked javascript code is just wrong.
you should also write your Javascript code in a CDATA section, otherwise an error will be thrown on every &, < and >.

True, or put it in a file and include it.
