Input-masking NPM

Input Masking

Introduction

This is a fork of Estelle Wyel's input-masking adapted specifically for use in React projects.

Where possible, I maintained the spirit of the original project - particularly the intent to have styleable, accessible input forms.

Features

input-mask enables you to include a mask on any input where a specific data entry format is required. The placeholder text remains in place, displaying which characters still need to be included. The placeholder is CSS styleable.

The user can enter letters and numbers. All other characters, like spaces, dashes, and parenthesis are automatically added by the script, making data entery easier when using dynamic keypads.

Example

Quick Start

Install input-masking in your project: npm i input-masking

To use:

import { MaskedInput } from "input-masking";

<MaskedInput
  id="expiration"
  type="tel"
  placeholder="MM/YY"
  pattern="(1[0-2]|0[1-9])\/(1[5-9]|2\d)"
  data-valid-example="05/18"
  label="Credit Card Expiration"
/>;

Accessibility

There are accessibility features baked into the examples that you must maintain to maintain accessibility.

Always include a label for each form control, and associate the form control either implicitly by nesting it, or explicitly with the htmlFfor and id attributes.
Always include a title attribute that describes the expected pattern when including the pattern attribute.
Always use the best input type for the job, so dynamic touchpad users get the right touchpad for the job. Generally this will always be type="tel", as most masking is for digits only. However, when alphanumeric characters are required, use type="text". And, while I've included an expiration month to show an example of using complex regular expressions, use type="month" instead of this script.

Customization

Initalization

If you are ok with all the default options you can have masked-inputs initalize it self and avoid writing any JavaScript at all. Simplu add the attribute data-autoinit="false" to your script tag

<script src="path/js/masking-input.js" data-autoinit="true"></script>

ReactJS version

var React = require('react'), MaskedInput = require('../index'); window.onload =
function () { React.render(
<ul>
  <li>
    <label htmlFor="month">Month</label>
    <MaskedInput
      id="month"
      type="tel"
      placeholder="MM/YY"
      pattern="(1[0-2]|0[1-9])\/\d\d"
      data-valid-example="11/18"
      title="2-digit month and 2-digit year greater than 01/15"
    />
  </li>
  <li>
    <label htmlFor="zip">Zip Code</label>
    <MaskedInput
      id="zip"
      type="tel"
      placeholder="XXXXX"
      pattern="\d{5}"
      required
      title="5-digit zip code"
    />
  </li>
</ul>
, document.getElementById('component') ); };
