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 (without jQuery)
To use, you'll need to include the Card JavaScript files into your HTML. You can find the necessary file at /lib/js/card.js
and include it in your HTML like so.
<script src="/path/to/card.js"></script>
Once you've included those files, you can initialize Card.
var card = new Card({
form: 'form',
container: '.card-wrapper',
formSelectors: {
numberInput: 'input#number',
expiryInput: 'input#expiry',
cvcInput: 'input#cvc',
nameInput: 'input#name'
},
width: 200,
formatting: true,
messages: {
validDate: 'valid\ndate',
monthYear: 'mm/yyyy',
},
placeholders: {
number: '•••• •••• •••• ••••',
name: 'Full Name',
expiry: '••/••',
cvc: '•••'
},
debug: false
});
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>
<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>
<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>
<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 /lib/js/jquery.card.js
and include it in your HTML like so.
<script src="/path/to/jquery.card.js"></script>
Once you've included those files, you can initialize Card with jQuery.
$('form').card({
container: '.card-wrapper',
});
Using with other javascript libraries
Card has wrappers that make it easy to use with other javascript libraries:
Angular
Ember
React
