<script type="text/javascript">

  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 < 6){
        alert("Error: Password must contain at least six characters!");
        form.pwd1.focus();
        return false;
      }
      if(form.pwd1.value == form.username.value) {
        alert("Error: Password must be different from Username!");
        form.pwd1.focus();
        return false;
      }
      re = /[0-9]/;
      if(!re.test(form.pwd1.value)) {
        alert("Error: password must contain at least one number (0-9)!");
        form.pwd1.focus();
        return false;
      }
      re = /[a-z]/;
      if(!re.test(form.pwd1.value)) {
        alert("Error: password must contain at least one lowercase letter (a-z)!");
        form.pwd1.focus();
        return false;
      }
      re = /[A-Z]/;
      if(!re.test(form.pwd1.value)) {
        alert("Error: password must contain at least one uppercase letter (A-Z)!");
        form.pwd1.focus();
        return false;
      }
    } else {
      alert("Error: Please check that you've entered and confirmed your password!");
      form.pwd1.focus();
      return false;
    }

    alert("You entered a valid password: " + form.pwd1.value);
    return true;
  }

</script> <form ... onsubmit="return checkForm(this);"> <p>Username: <input type="text" name="username"></p> <p>Password: <input type="password" name="pwd1"></p> <p>Confirm Password: <input type="password" name="pwd2"></p> <p><input type="submit"></p> </form>

I see in your code that you check for at least 6 characters, I'm not sure what trouble you are having checking for 8.

Thank you Rabbit for your prompt reply to my query.
my trouble is that I want to validate exact number of characters, not less, no more than 6 but exactly six characters.

[Exequiel]

you can do it this way.

if(form.pwd1.value.length == 6)
