Cleave.js

Cleave.js has a simple purpose: to help you format input text content automatically.

Features

• Credit card number formatting
• Phone number formatting (i18n js lib separated for each country to reduce size)
• Date formatting
• Numeral formatting
• Custom delimiter, prefix and blocks pattern
• CommonJS / AMD mode
• ReactJS component
• AngularJS directive (1.x)
• ES Module

TL;DR the demo page

Why?

The idea is to provide an easy way to increase input field readability by formatting your typed data. By using this library, you won't need to write any mind-blowing regular expressions or mask patterns to format input text.

However, this isn't meant to replace any validation or mask library, you should still sanitize and validate your data in backend.

Installation

npm

npm install --save cleave.js

CDN

cleave.js is available on jsDelivr and on cdnjs.com

old school

Grab file from dist directory

Usage

Simply include

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

cleave-phone.{country}.js addon is only required when phone shortcut mode is enabled. See more in documentation: phone lib addon section

Then have a text field

<input class="input-phone" type="text"/>

Now in your JavaScript

var cleave = new Cleave('.input-phone', {
    phone: true,
    phoneRegionCode: '{country}'
});

.input-element here is a unique DOM element. If you want to apply Cleave for multiple elements, you need to give different CSS selectors and apply to each of them, effectively, you might want to create individual instance by a loop, e.g. loop solution

More examples: the demo page

CommonJS

var Cleave = require('cleave.js');
require('cleave.js/dist/addons/cleave-phone.{country}');

var cleave = new Cleave(...)

AMD

require(['cleave.js/dist/cleave.min', 'cleave.js/dist/addons/cleave-phone.{country}'], function (Cleave) {
    var cleave = new Cleave(...)
});

ES Module

// Rollup, WebPack
import Cleave from 'cleave.js';
var cleave = new Cleave(...)

// Browser
import Cleave from 'node_modules/cleave.js/dist/cleave-esm.min.js';
var cleave = new Cleave(...)

TypeScript

Types are contributed by the community and are available via npm install --save-dev @types/cleave.js. Once installed, you can import Cleave like the following:

import Cleave = require('cleave.js');

Types for the React-component are also available and can be imported in the same way.

import Cleave = require('cleave.js/react');

ReactJS component usage

import React from 'react';
import ReactDOM from 'react-dom';

import Cleave from 'cleave.js/react';

Then in JSX:

class MyComponent extends React.Component {

    constructor(props, context) {
        super(props, context);
        this.onCreditCardChange = this.onCreditCardChange.bind(this);
        this.onCreditCardFocus = this.onCreditCardFocus.bind(this);
    }

    onCreditCardChange(event) {
        // formatted pretty value
        console.log(event.target.value);

        // namespaced raw value
        console.log(event.target.cleaveRawValue);
    }

    onCreditCardFocus(event) {
        // update some state
    }

    render() {
        return (
            <Cleave placeholder="Enter your credit card number"
                options={{creditCard: true}}
                onFocus={this.onCreditCardFocus}
                onChange={this.onCreditCardChange} />
        );
    }
}

As you can see, here you simply use <Cleave/> as a normal <input/> field

• Attach HTML <input/> attributes
• Pass in the custom options prop
• Add ReactJS onChange event listener

Advanced usage:

• How to pass default value
• How to get ref of cleave instance and call methods
• How to update raw value
• How to get ref of the input field
• How to use it with redux form

Usage for Webpack, Browserify and more in documentation: ReactJS component usage

AngularJS directive usage

First include the directive module:

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

And in your model:

angular.module('app', ['cleave.js'])

.controller('AppController', function($scope) {
    $scope.onCreditCardTypeChanged = function(type) {
        $scope.model.creditCardType = type;
    };

    $scope.model = {
        cleaveRawValue: ''
    };

    $scope.options = {
        creditCard: {
            creditCard: true,
            onCreditCardTypeChanged: $scope.onCreditCardTypeChanged
        }
    };
});

Then easily you can apply cleave directive to input field:

<div ng-controller="AppController">
    <input ng-model="model.cleaveRawValue" ng-whatever="..." type="text" placeholder="Enter credit card number"
        cleave="options.creditCard"/>
</div>
