Cut & Paste Max # of characters check
Description: A script that checks the number of characters in a form box, and if it exceeds the predetermined number, cancels the form submission, and asks the surfer to reenter data. Note that the validation occurs after the user presses the submit button.
Directions: Simply cut and paste the below code into the <body> section of your page. It contains a form with one textarea box that is checked for max # of characters. You can change this # from the default 50 to another by changing "var maxlength" below. You can add in more form elements into the form, as you would with any other form.
