Smart Validate is a jQuery credit card validation plugin, that makes credit card format validation a simple task. It ensures that user has entered valid credit card number before making actual transaction. Smart Validate supports the following credit cards.

  • American Express
  • Master Card
  • Visa Card
  • Diners Club
  • Discover

Using Smart Validate

In your HTML file add the following in the head section.

  • Add a reference to latest jQuery script
  • Add a reference to ccvalidate.js file
  • Add a reference to ccvalidate.css file

Add the code below to your HTML document or use classes "cc-ddl-type", "cc-card-number" and "cc-checkout" to existing elements. These classes are mandatory as the smart validate plugin uses these classes to read the required values.

<select class="cc-ddl-type">
<option value="mcd">Master Card</option>
<option value="vis">Visa Card</option>
<option value="amx">American Express</option>
<option value="dnr">Diner Club</option>
<option value="dis">Discover</option>
</select>
<input class="cc-card-number" type="text">
<input class="cc-checkout" value="Checkout" type="submit">

Smart Validate plugin has only one parameter that is a callback function to be called, that returns a boolean value indicating whether the credit card number is in valid format or not. See the example below to see how it works.

$('.cc-container').ccvalidate({ onvalidate: function(isValid) {
               if (!isValid) {
                   alert('Incorrect Credit Card format');
                   return false;
               }
           }

Here is the full code for the example above.
