Checkbox Validation

Shaji Kalidasan Feb 24, 2007

"This simple JavaScript allows you to check up to three checkboxes (allows a maximum of three out of five). When a user selects a fourth checkbox, an alert message is shown and upon 'ok,' it automatically deselects the fourth one. This script can easily be configured for any number of checkboxes. You can freely use this script. No Linkback or credits required."
