Features

Expected to work with...

IE9+, Android, Samsung Internet, Windows Phone, iOS, Opera, Firefox, Safari, and Chrome

Masking characters

Character | Description --- | --- 1 | Any number A | Any letter ? | Any number or letter U | Any letter (will be transformed to uppercase) L | Any letter (will be transformed to lowercase)

Escapable masking characters

The mask also supports escaping, so you can use a masking character within the mask. For example

+\1 (111) 111-1111

The first 1 is not a masking character but part of the mask. For more information, see the documentation here.

Guide mode

Guide mode prints out placeholder characters and the mask itself as the user types

No-guide mode

No-guide mode doesn't print out placeholder characters and only adds mask characters when the user reaches them

Ability to customize placeholder character

You can change the placeholder character from _ (underscore) to anything you want. For example, you can use the unicode character U+2000 (\u2000 in JavaScript), which is white space to create a mask for phone number that looks like

+1 (   )    -    

Or for date

  /  /
