I am looking for a javascript function ( don't know what they call ths

The example has all the ideas I would use. Below it is just changed a
little with a few suggestions that might help sometimes.
There is no need for the language attribute of the script tag. It is
deprecated.
<http://www.w3schools.com/tags/tag_script.asp>
The comment script hiding technique is not needed anymore. It was for
some browsers in 1995 or a similarly long time ago.
Use a doctype.
Use double quotes around attribute values for valid markup.

In the following example the script in the head element could be in a
separate JavaScript file so that the browser can cache it.
The following uses the widely supported but non-standard innerHTML
property. This could be changed to standard compliant code.
The first argument to setTimeout can be a function or a string. I like
a function.
