Anywhere Mail...
This is a neat little JavaScript button that will help you to e-mail anyone. Just click 'E-Mail Someone!' and JavaScript will ask you for the necessary information - e-mail address, subject, etc. Then, a new mail message is opened for you. Neat!
Check Entry...
Prevents the user from selecting a filename with a space (known to cause problems with some CGI-scripts). The visitor are informed that the field can not have spaces. Of course, you could change the character it checks for as well as the invalid alert message to something else to suit your needs. Nice!
Confirmable Order Form...
JavaScript can take the contents of an HTML order form, process them, and display the order for verification even including the grand total! When the user confirms the order by clicking the button, the order is emailed to you by using freedback.com's free form processor cgi script. This script does take a bit of modification, but surely is worth it if you sell anything online.
Controlled Boxes...
This script allows checkboxes to check and uncheck based on the selection in another checkbox. If the ALL box is checked, all the other choices go unchecked. If another choice is checked, then the ALL box goes unchecked. Useful when constructing search forms, surveys, and more!
Credit Card Validation...
Validates a credit card number the user enters based on the rules of that card such as the value of first digit, the number of digits, as well as several other computations. Useful for online order form validation. Note: Although this form does not capture your credit card information, if you do not feel comfortable entering your credit card number to test this script, please DO NOT !
Customised Window...
Use JavaScript to allow visitors to open a customized window. I've used this script in the past to find the exact window size I want a JavaScript function to open.
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)
