/** * strongPass.js * * This script provides a rudimentary check of the * strength of a password. It is not able to check * the password against a dictionary to prevent users * from using common words or phrases, but it does * check that the password contains upper- and lower- * case letters, numerals, and symbols. For an * example, check out: * http://projects.jamessocol.com/scripts/javascript/strongPass.js.htm * * LICENSE: This product is freeware. Please feel * free to use, modify and distribute, and to learn * from it.

with a fixed width (in pixels) or a table cell * and give it the following ID attribute: * id="passStrength" * for example: * * Make sure no other elements of the page use this ID. * Then add the following attribute to your password field: * onKeyUp="strongPass(this);" * for example: * * Finally, add the following to the section of * your page: * * Then you're done! * * @package turnThePage * @author James Socol * @version 1.0 * @date 20 July 2006 */ function strongPass (input) { var text = new Array('
