Flexible Form Input Text Format Library – Cleave.js

Cleave.js is a simple lightweight JavaScript library used to restrict and format input text to a specific pattern (credit cards, phone numbers, dates, etc).

AMD and commonJS are supported. Also provides as a React component.

Basic usage:

You first have to include the Cleave.js library on the webpage.

<script src="cleave.min.js"></script>

Include an addon of your choice as this:

<script src="addons/cleave-phone.{country}.js"></script>

Create a new Cleave object, specify the target input field and pass in the options as follows:

new Cleave('.input', {
    // options here
});

All possible options.

// credit card
