Jquery Masked Input Plugin


This is a masked input plugin for the jQuery javascript library. It allows a user to more easily enter fixed width input where you would like them to enter the data in a certain format (dates,phone numbers, etc). It has been tested on Internet Explorer, Firefox, Safari and Chrome.A mask is defined by a format made up of mask literals and mask definitions. Any character not in the definitions list below is considered a mask literal. Mask literals will be automatically entered for the user as they type and will not be able to be removed by the user.The following mask definitions are predefined:

  • a – Represents an alpha character (A-Z,a-z)
  • 9 – Represents a numeric character (0-9)
  • * – Represents an alphanumeric character (A-Z,a-z,0-9)
  • jquery.maskedinput-1.3.js

First, include the jQuery and masked input javascript files.

<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.maskedinput.js" type="text/javascript"></script>

Next, call the mask function for those items you wish to have masked.

jQuery(function($){
   $("#date").mask("99/99/9999");
   $("#phone").mask("(999) 999-9999");
   $("#tin").mask("99-9999999");
   $("#ssn").mask("999-99-9999");
});

Optionally, if you are not satisfied with the underscore (‘_’) character as a placeholder, you may pass an optional argument to the maskedinput method.

jQuery(function($){
   $("#product").mask("99/99/9999",{placeholder:" "});
});

Optionally, if you would like to execute a function once the mask has been completed, you can specify that function as an optional argument to the maskedinput method.

jQuery(function($){
   $("#product").mask("99/99/9999",{completed:function(){alert("You typed the following: "+this.val());}});
});

You can now supply your own mask definitions.

jQuery(function($){
   $.mask.definitions['~']='[+-]';
   $("#eyescript").mask("~9.99 ~9.99 999");
});

You can have part of your mask be optional. Anything listed after ‘?’ within the mask is considered optional user input. The common example for this is phone number + optional extension.

jQuery(function($){
   $("#phone").mask("(999) 999-9999? x99999");
});
