Validation (password)

Russ Swift Feb 2, 2001
This script works like our Password Verifier, however, it also checks for a minimum length and invalid characters.
Enter your password twice.
(At least 6 characters, 12 characters max, and spaces are not allowed.)

Password:
Verify password:

The JavaScript Source: Forms: Validation (password)

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Command-s). The script is yours!!!

    

Did you use this script?  Do you like this site?  Please link to us!

It doesn't work on this page, and it doesn't work on mine either. I figured I'd save time and rather than reinvent the wheel, I'd use yours but the submit button doesn't call the script it seems... Can you figure out why? Thanks

[removed] function checkForm(form) { if(form.username.value == "") { alert("Error: Username cannot be blank!"); form.username.focus(); return false; } re = /^\w+$/; if(!re.test(form.username.value)) { alert("Error: Username must contain only letters, numbers and underscores!"); form.username.focus(); return false; } if(form.pwd1.value != "" && form.pwd1.value == form.pwd2.value) { if(form.pwd1.value.length
