This script uses Prototype library - unobtrusive JavaScript to implement "input masks". The maximum field length is automatically limited to the length of the mask. The characters that are entered into the fields are constrained, and separators are automatically added. (No actual validation is done. Check our site for validation scripts.)

Color alternate rows, sort rows and columns in ascending or descending order, all by just adding a className. Easy to use!

Create an auto-complete or auto-suggest text box in JavaScript, without use of prototype handlers and other advanced techniques. This script could be adapted for use in a number of different situations.

This script reveals information, based on the user's selection in a drop down box. Can be used for a FAQ, contact info, and more. Short and sweet, with comments.

With the help of this JavaScript you can put up a textbox on your Web page that displays alternating messages for your visitors. It saves space, as a lot of text can be contained in a minimal display area.

This JavaScript will adjust capitalization of names (actually, the content of any form field you apply to it) so the first letter of each word is capitalized and the rest are lowercase. This is so easy to implement!

Tired of customers using characters that could possibly render your forms useless? This JavaScript prevents a user from entering certain special characters in designated form fields.

This JavaScript will place the cursor in a designated textbox, causing its background to blink a specified color for a pre-determined amount of seconds. This will highlight the textbox on the Web page in order to draw attention to it.

When testing forms you don't need to keep filling in the different fields. Use this function to automatically fill-in input blocks and select values in the form for you. Very easy to use.

This is a JavaScript custom object that uses an array assigned to an input text box. It will fire on the onkeyup event and read from the array and act accordingly. It is very simple to use.
