Card - check out the demo

A better credit card form in one line of code

Card will take any credit card form and make it the best part of the checkout process (without you changing anything). Everything is created with pure CSS, HTML, and Javascript — no images required.

Usage

To use, you'll need to include the correct CSS and Javascript files into your HTML. You can find the necessary files at /lib/js/card.js and /lib/css/card.css and include them in your HTML like so.

<!-- in HEAD -->
<link rel="stylesheet" href="/path/to/card.css">
<!-- at the end of BODY -->
<script src="/path/to/jquery.js"></script>
<script src="/path/to/card.js"></script>

Once you've included those files, you can initialize Card.

$('form').card({
    // a selector or jQuery object for the container
    // where you want the card to appear
    container: '.card-wrapper', // *required*
    numberInput: 'input#number', // optional — default input[name="number"]
    expiryInput: 'input#expiry', // optional — default input[name="expiry"]
    cvcInput: 'input#cvc', // optional — default input[name="cvc"]
    nameInput: 'input#name', // optional - defaults input[name="name"]

    width: 200, // optional — default 350px
    formatting: true, // optional - default true

    // Strings for translation - optional
    messages: {
        validDate: 'valid\ndate', // optional - default 'valid\nthru'
        monthYear: 'mm/yyyy', // optional - default 'month/year'
    },

    // Default values for rendered fields - options
    values: {
        number: '•••• •••• •••• ••••',
        name: 'Full Name',
        expiry: '••/••',
        cvc: '•••'
    },

    debug: false // if true, will log helpful messages for setting up Card
});

Using multiple inputs for one field

Card can be used in forms where you have multiple inputs that render to a single field (i.e. you have a first and last name input). To use Card with this functionality, just pass in a jQuery selector that selects the fields in the correct order. For example,

<form>
    <input type="text" name="number">
    <input type="text" name="first-name"/>
    <input type="text" name="last-name"/>
    <input type="text" name="expiry"/>
    <input type="text" name="cvc"/>
</form>
<script>
$('form').card({
    container: '.card-wrapper',
    nameInput: 'input[name="first-name"], input[name="last-name"]'
});
</script>

Rendering with different initial card values

Card renders with default values for card name, number, expiry, and cvc. To override these values, you can either pass in a values object or set $.card.values before initializing card. Do one or the other, not both.

<script src="/path/to/card.js"></script>
<form>
    <input type="text" name="number">
    <input type="text" name="name"/>
    <input type="text" name="expiry"/>
    <input type="text" name="cvc"/>
</form>
<script>
// setting $.card.values is one way to override
// the default card values
$.card.values = {
    number: '**** **** **** ****',
    name: 'Arya Stark',
    expiry: '**/****',
    cvc: '***'
}

$('form').card({
    container: '.card-wrapper',

    // passing in a messages object is another way to 
    // override the default card values
    values: {
        number: '**** **** **** ****',
        name: 'Arya Stark',
        expiry: '**/****',
        cvc: '***'
    }
});
</script>

Translation

To render the card with the strings in a different language, you can either pass in a messages object or set $.card.messages before initializing card. Do one or the other, not both.

<script src="/path/to/card.js"></script>
<form>
    <input type="text" name="number">
    <input type="text" name="name"/>
    <input type="text" name="expiry"/>
    <input type="text" name="cvc"/>
</form>
<script>
// setting $.card.messages is one way to override
// the default field names
$.card.messages = {
    validDate: 'expire\ndate',
    monthYear: 'mm/yy'
}

$('form').card({
    container: '.card-wrapper',

    // passing in a messages object is another way to 
    // override the default field names
    messages: {
        validDate: 'expire\ndate',
        monthYear: 'mm/yy'
    }
});
</script>
