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.

card

Usage (without jQuery)

To use, you'll need to include the Card JavaScript files into your HTML, no CSS link is necessary as the JavaScript file does this for you. You can find the necessary file at /dist/card.js and include it in your HTML like so.

<!-- at the end of BODY -->
<!-- CSS is included via this JavaScript file -->
<script src="/path/to/card.js"></script>

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

var card = new Card({
    // a selector or DOM element for the form where users will
    // be entering their information
    form: 'form', // *required*
    // a selector or DOM element for the container
    // where you want the card to appear
    container: '.card-wrapper', // *required*

    formSelectors: {
        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 placeholders for rendered fields - optional
    placeholders: {
        number: '•••• •••• •••• ••••',
        name: 'Full Name',
        expiry: '••/••',
        cvc: '•••'
    },

    masks: {
        cardNumber: '•' // optional - mask card number
    }

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

Installing card from bower

If you're using bower, you can install card.js with:

bower install card --save

Installing card from npm

If you're using npm, you can install card.js with:

npm install --save card

var $ = require("jquery");
// The current card.js code does not explictly require jQuery, but instead uses the global, so this line is needed.
window.jQuery = $;
var card = require("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 selector that selects the fields in the correct order. For example,

<html>
<body>
<div class='card-wrapper'></div>
<!-- CSS is included via this JavaScript file -->
<script src="/path/to/card.js"></script>
<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>
var card = new Card({
    form: 'form',
    container: '.card-wrapper',

    formSelectors: {
        nameInput: 'input[name="first-name"], input[name="last-name"]'
    }
});
</script>
</body>
</html>

Rendering with different initial card placeholders

Card renders with default placeholders for card name, number, expiry, and cvc. To override these placeholders, you can pass in a placeholders object.

<html>
<body>
<div class='card-wrapper'></div>
<!-- CSS is included via this JavaScript file -->
<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>

var card = new Card({
    form: 'form',
    container: '.card-wrapper',

    placeholders: {
        number: '**** **** **** ****',
        name: 'Arya Stark',
        expiry: '**/****',
        cvc: '***'
    }
});
</script>
</body>
</html>

Translation

To render the card with the strings in a different language, you can pass in a messages object.

<html>
<body>
<div class='card-wrapper'></div>
<!-- CSS is included via this JavaScript file -->
<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>

var card = new Card({
    form: 'form',
    container: '.card-wrapper',

    messages: {
        validDate: 'expire\ndate',
        monthYear: 'mm/yy'
    }
});
</script>
</body>
</html>

Using with jQuery

To use with jQuery, you'll need to include the jquery.card.js file into your HTML. You can find the necessary file at /dist/jquery.card.js and include it in your HTML like so.

<!-- at the end of BODY -->
<!-- CSS is included via this JavaScript file -->
<script src="/path/to/jquery.card.js"></script>

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

$('form').card({
    // a selector or DOM element for the container
    // where you want the card to appear
    container: '.card-wrapper', // *required*

    // all of the other options from above
});

Using with other javascript libraries

Card has wrappers that make it easy to use with other javascript libraries:

Angular (1.x Currently)

Ember

React
