Hi,
I'm making a Custom Web Control and I'm wondering how I can insert Javascript code into the head part of the document from within my web control... I lloked at the methods of the HtmlTextWriter output object from the Render method, but I didn't fiind anything. I have 2 questions :

1. Is it this important to put the javascript code into the head or it can be in the body without causing trouble?

It is not vital that JavaScript be placed in the HEAD part of the HTML page. It is recommended, because the JavaScript parser will ready all the functions placed there before starting to render the body, but it is not a must.

Just make sure that your JavaScript code is placed before the call to it, the best being placing the code in functions, and calling the functions from an "onload" event of the body tag. Since the "onload" event is fired only after the whole code (HTML and JavaScript) is parsed and prepared, you're sure that your JavaScript environment is ready.

2. If it is important to put it in <Head>, how can I do it from my Web Control?

You can't with the default Page class. When I really have (or want to) place code in the HEAD part, I use a self-written Custom control which I use to register headers (CSS files, JavaScript files or code). Not the most elegant way, but it works.


Thanks a lot.
