Hi Phillip,

You may start from http://www.w3schools.com/js/js_functions.asp tutorials. You can also use www.tek-tips.com JavaScript forum.

Of course, you can reuse functions, once defined. Just include file with your JavaScript functions (usually file with .js extension).

One more good place: http://www.dynamicdrive.com/dynamicindex5/index.html

Also View Source for this site as well.

One very good article, I read quite recently:
http://www.atgconsulting.com/oodynlistbox.asp

Also try to search on google.com by JavaScript Form Validation. I'm sure, you would be able to find several good artciles on the topic.

>I was wondering if anyone out there reused javascript functions in the way you would use a procedure library in other environments. I am initialy thinking along the lines of storing functions in separate files and using includes to pick appropriate ones (like the one mentioned above) and then calling the function with parameters that identify the necessary elements of the particular form. That's where the idea gets messy. Can you pass arrays as parameters?
