    Thumbs up The password strength meter for magento form

    Magento Password strength meter brings user interaction with forms. Magento provides built in support for form validation. However if it provides a nice Interactive validation response it would increase the user experience. Lets say while creating a password it would be nice if the user gets to know about the strength of his password.

    So we write a simple javascript function to achieve this functionality in the customer registration form.

    Step 1: First we add the required UI Elements under the password Field. A Few div tags to show the password strength messages as shown below

    HTML Code:
    <div id="password-strength-container" style="display:none">
     <div id="password-strength-text" style= "font-weight:bold">
     </div>
     
    <div id="strength-indicator" style="width: 10%; height: 0.5em;"></div> </div> </div>

    Step 2: Now We need to Write the actual javascript function. Since magento uses the prototype javascript
    library we follow the prototype style code implementation.

    Step 3: Our Custom Javascript code will be implemented under the form tag. First we need to handle the Events. Whenever a User enters some value in the password field our function should get executed.

    HTML Code:
    <script type="text/javascript">
    Event.observe("password","keydown", function() {
     $("password-strength-container").show();
     var passinput = $("password").value;
     if(passinput.length < 6) {
      $("password-strength-text").update("Weak");
      $("strength-indicator").setStyle({
         backgroundColor: '#EB34OA',
         width: '15%'
      });
    } 
     else if( passinput.length > 6 && passinput.match(/[^a-zA-Z0-9] +/) ) {
       $("password-strength-text").update("Strong");
      $("strength-indicator").setStyle({
         backgroundColor: '#47C965',
         width: '75%'
      });
     }
     else {
     $("password-strength-text").update("Medium");
      $("strength-indicator").setStyle({
         backgroundColor: '#FFFF00',
         width: '35%'
      });
    }
    
    });
    Event.observe("password","keydown", function() {
     $("password-strength-container").hide();
     });
     
    </script>
    Step 4: The above code snippet gives hints about the strength of the password he entered. if the password contains less than 6 characters it would indicate the password strength as Weak, if the password is more than 6 characters and also have lower case and uppercase characters with numeric digits it is considered as strong password.
