JavaScript is the functionality behind Dynamic HTML, and while I am not the JavaScript Guide, I often get questions about how to do things "using HTML" that can actually only be done using JavaScript. While I am not an expert on JavaScript, if you're interested in learning DHTML, you can start with these simple scripts to make your pages more dynamic. To learn JavaScript, please check out Robert's site.

Validating Forms
Using JavaScript is a common way to validate forms. I've written another article on how to do most form validation, but I left a couple of things out. Here are some other validations that you can do:

• force the characters in a text field to be all lowercase
  
  Type something (with capital letters):
  
  View the Source



• limit the characters in a textarea field
  Try to submit more than 10 characters:
  
  View the Source

These scripts are fairly simple. If you are looking to do more complex things with your JavaScript, you should check the JavaScript site at About.
