Currency Format
This script accepts a number or string and formats it like U.S. currency. Adds the dollar sign, rounds to two places past the decimal, adds place holding zeros, and commas where appropriate. Occurs when the user clicks the button or when they finish entering the money amount (and click into the next field).

Day Menu
Do you need your visitors to select a day from this month? Here's an excellent way to do so - they get a pulldown menu containing the entire month and the current day is already selected! Cool!
Decimals Allowed
Allows the user to enter a number with up to 2 decimal places in a text box. In other words, 99 is ok, 99.9 is ok, 99.99 is ok, but 99.999 is rejected. You can easily change the number of decimal places that are permitted. (i.e. 1, 2, 3, etc.) For the example, enter a number with up to 2 decimal places then try entering one with more than 2 decimal places.
Disable Submit
(Internet Explorer only) When the form is submitted, any submit and reset buttons are disabled. This prevents the user from submitting the form repeatedly, whether by accident or on purpose. The form will just act normally for Netscape users. Great!
Dynamic Input
(Internet Explorer Only) Offer a form with as many input boxes that the user selects. After entering the number of boxes, the form is dynamically updated while the rest of the form remains untouched.
Dynamic Table
(Internet Explorer 5+ and Netscape 6+ Only) Enter information into this dynamic table and see the power of W3C-DOM compatible browsers. Absolutely Amazing!
Email Address Validation
This is an e-mail address validation function. It allows the usual user@domain syntax, but in addition allows user@[ip] format as well as "User with Spaces"@domain or [ip], all of which are legal syntax, according to W3C. It also checks that the user hasn't done anything silly like having multiple @'s or continuous .'s in the address (e.g. jim@b@c.com and jim@c..b.co.uk).
Email Domain
Takes an email address and returns just the domain - the stuff after the "@" sign. We've put it together with a simple WHOIS query, neat!
Encode Special Characters
When submitting the form "GET" method, JavaScript can encode special characters with the escape() function. Great! (Enter a nickname or password with some special variables then click 'submit' to see the web address which contains the encoded (%xx) characters.)
Word Count
Finally, an easy way to count the number of words that are entered into a form!
