How to string length through javascripts in PHP

Jul 15th, 2008

Hey Guys,
I am new to PHP and know nothing of java scripts. I have to build a web page where user enters login information at the time of registration. I have taken help of a PHP tool to generate the required scripts. Now in that I have to incorporate a functionality to check the password length and give appropiate message if password is too short. I think I could enter this functionality through javascripts but I don't know how. I am attaching the file in which the PHP scripts are written. Please help me out.

This is how you get the length of a string.

javascript Syntax (Toggle Plain Text)

var stringlen = stringvarname.length;

BTW: its all html when it hits the browser
