Hi guys,

My requirement is that a password string be validated in JavaScript:

(It should work for both firefox 3.0 and internet explorer 6 and IE7)

1. It must have ONE UPPERCASE.

2. It must have ONE LOWERCASE.

3. It must have ONE DIGIT.

4. SPECIAL CHARACTER is not mandatory.


I am using the regular expression:

var re = /(?=\w*[0-9])(?=\w*[a-z])(?=\w*[A-Z])\w*/;


Here the problem is that Abcd1@123 works.

However Abcd@123 does not work. I think the '@123' is being matched to \w*. Thus the condition of (?=\w*[0-9]) , that a digit is a mandatory is not being satisfied and my password match is failing. Anything after a special character is not being checked.


Plz help me to do this..

Thanks in advance
