Tutorial: HTML Forms Limiting Checkbox Use Tutorial

Here's a script that limits the number of checkboxes a person can choose.

Tutorial Details:

HTML Forms Limiting Checkbox Use Tutorial
Here's a fantastic effect. As you know, multiple checkboxes are often avoided in forms because users have a tendency to simply check all the boxes no matter what. Radio buttons have become the preferred element when a choice must be made. You mostly see checkboxes used as single items. I see them mostly at the end of larger forms asking if I want to receive a newsletter or email updates about a product I'm downloading.

But what if you want a user to choose two from say, five elements?
Well, here's a script that you can attach to your forms that will allow you to limit the number of checks your users can make. You'll fall in love with checkboxes all over again. I got the original idea for this script from The Codeman. He has a similar script that only worked in Internet Explorer. I took the concept and rewrote it so that the script would work across browsers.

Did you see it? Not only did you get that nasty alert window but you also had your third choice unclicked. Take that! Of course you can set the script to allow as many or as few clicks as you'd like, but in order to do that you need to understand how this puppy works. So let's get into it.

The Form Elements I only have checkboxes in the example, but you can surround them with any number of extra form elements. I just singled out the form checkboxes for demonstration purposes.
