Default Settings

The keypad functionality can easily be added to a text field with appropriate default settings. Use it with a password field for more secure text entry.
You can also remove the keypad widget if it is no longer required.

Default keypad:    

$('#viewKeypad').click(function() {
	alert('The current value is: ' + $('#defaultKeypad').val());

$('#removeKeypad').toggle(function() {
	function() {

The defaults are:

You can override the defaults globally as shown below:

$.keypad.setDefaults({prompt: 'Please use the keypad'});

Processed fields are marked with a class of is-keypad and are not re-processed if targeted a second time.


You can trigger the keypad by focus on the field (the default), via an associated button, or by both. Disable or enable the fields and their triggers via a command.

Button only trigger:  

$('#buttonKeypad').keypad({showOn: 'button'});

$('.buttonDisable').toggle(function() {
	}, function() {

Image only trigger:  

$('#imageKeypad').keypad({showOn: 'button',
	buttonImageOnly: true, buttonImage: 'img/keypad.png'});

Focus and button trigger:  

$('#bothKeypad').keypad({showOn: 'both',
	buttonImage: 'img/keypad.png'});

You can also control the animation used to display the keypad and its duration. There are three standard animations (show, fadeIn, slideDown) as well as the ones from the jQuery UI effects package. Additional options for the latter may be specified with the showOptions setting.

Show :

$('#animKeypad').keypad({showOn: 'both'});

var anims = ['show', 'fadeIn', 'slideDown', 'blind', 'blind', 'bounce', 'clip',
	'clip', 'drop', 'drop', 'fold', 'fold', 'slide', 'slide', ''];
var animOpts = [null, null, null, {}, {direction: 'horizontal'}, {}, {},
	{direction: 'horizontal'}, {}, {direction: 'up'}, {},
	{horizFirst: true}, {}, {direction: 'up'}, {}];

$('#duration,#animation').change(function() {
	var index = parseInt($('#animation').val(), 10);
	$('#animKeypad').keypad('option', {showAnim: anims[index],
		showOptions: animOpts[index], duration: $('#duration').val()});
Inline Keypad

You can present the keypad inline by applying it to a div or span. Make use of the value entered via the onKeypress or onClose callbacks. Or connect it with an external input field via the target setting.

Inline keypad:  

$('#inlineKeypad').keypad({onClose: useValue, prompt: '',
	closeText: 'Done', closeStatus: 'Use this value'});
function useValue(value) {
	alert('The entered value is ' + value);

$('#inlineDisable').toggle(function() {
	}, function() {

With a textarea:

$('#inlineTextKeypad').keypad({onKeypress: appendValue, prompt: '',
	layout: ['àáâãäåæçèéêë', 'ìííîïñòóôõöø',
	'ðþùúûüýÿ' + $.keypad.ENTER + $.keypad.SHIFT]});
function appendValue(key) {
	var field = $('#inlineText');
	$.keypad.insertValue(field, key);

With multiple targets:

$('#inlineTargetKeypad').keypad({target: $('.inlineTarget:first'),
	layout: $.keypad.qwertyLayout});

var keypadTarget = null;
$('.inlineTarget').focus(function() {
	if (keypadTarget != this) {
		keypadTarget = this;
		$('#inlineTargetKeypad').keypad('option', {target: this});

You can alter the layout of the keypad by specifying the keys per row as a string array. Use special characters for controls:

The alphabetic character layout for the standard Qwerty keyboard is available from $.keypad.qwertyAlphabetic.

Qwerty keypad:

var qwertyLayout = [
	$.keypad.qwertyAlphabetic[0] + $.keypad.CLOSE,
	$.keypad.HALF_SPACE + $.keypad.qwertyAlphabetic[1] +
	$.keypad.HALF_SPACE + $.keypad.CLEAR,
	$.keypad.SPACE + $.keypad.qwertyAlphabetic[2] +
	$.keypad.SHIFT + $.keypad.BACK];
$('#qwertyKeypad').keypad({keypadOnly: false, layout: qwertyLayout});

Alphabetic keypad:

$('#alphaKeypad').keypad({keypadOnly: false,
	layout: ['abcdefghij' + $.keypad.CLOSE,
		'klmnopqrst' + $.keypad.CLEAR,
		'uvwxyz' + $.keypad.SPACE + $.keypad.SPACE +
		$.keypad.SHIFT + $.keypad.BACK]});

The full layout for the standard Qwerty keyboard is available from $.keypad.qwertyLayout.

Full keyboard entry:

$('#fullKeypad').keypad({keypadOnly: false,
	layout: $.keypad.qwertyLayout});

You can provide an extra level of security by randomising the positions of the keys each time the keypad appears. The keys are shuffled by type: alphabetic, numeric, and other.

Randomised numerics:

$('#randomKeypad').keypad({showOn: 'both', randomiseNumeric: true});

Randomised keyboard:


$('#randomKeyboard').keypad({showOn: 'both',
	randomiseNumeric: true, randomiseOther: true,
	layout: $.keypad.qwertyLayout});
$('.randomise').click(function() {
	$('#randomKeyboard').keypad('option', {
		randomiseAlphabetic: $('#alphabetic').is(':checked'),
		randomiseNumeric: $('#numeric').is(':checked'),
		randomiseOther: $('#other').is(':checked'),
		randomiseAll: $('#all').is(':checked')});
Unusual Characters

Use the keypad with a text field for entering unusual characters, whilst continuing to type normal characters.

Greek letters:

$('#greekKeypad').keypad({keypadOnly: false,
	layout: ['αβγδεζ', 'ηθικλμ', 'νξοπρσ', 'τυφχψω', $.keypad.SHIFT],
	prompt: 'Add these Greek letters'});

Mathematical symbols:

$('#mathKeypad').keypad({keypadOnly: false,
	layout: ['÷±≠≤≥', '½⅓⅔¼¾', $.keypad.SHIFT],
	toUpper: function(ch) {
		return {'÷': 'º', '±': '¹', '≠': '²', '≤': '³', '≥': 'ⁿ',
			'⅓': '⅛', '⅔': '⅜', '¼': '⅝', '¾': '⅞'}[ch] || ch;
	prompt: 'Mathematical symbols'});

Other symbols:

$('#otherKeypad').keypad({keypadOnly: false,
	layout: ['©®™℠', '€£¥¢'], prompt: 'Other symbols'});

Text area:

$('#areaKeypad').keypad({keypadOnly: false, prompt: '',
	layout: ['àáâãäåæçèéêë', 'ìííîïñòóôõöø',
	$.keypad.SHIFT + 'ùúûüýÿðþ' + $.keypad.CLOSE]});
Long Keys

You can have keys with more than a single character on them by providing a separator setting and delimiting the layout with it.

Dollar amount: $

$('#dollarsKeypad').keypad({separator: '|', prompt: '',
	layout: ['7|8|9|' + $.keypad.CLOSE,
		'4|5|6|' + $.keypad.CLEAR,
		'1|2|3|' + $.keypad.BACK,

US States:

$('#statesKeypad').keypad({prompt: 'Select a state',
	onKeypress: chooseState, separator: '|',
	layout: ['AK|AL|AR|AZ|CA|CO|CT|DE|FL|GA',
function chooseState(key) {
	alert('You chose ' + key);


$('#continentsKeypad').keypad({prompt: 'Select a continent',
	onKeypress: chooseContinent, separator: ',',
	layout: ['Africa,Europe', 'Antarctica,North America',
		'Asia,South America', 'Australia']});
function chooseContinent(key) {
	alert('You chose ' + key);
Control Keys

You can define additional control keys to execute your own actions via the addKeyDef function. Specify a variable name for including the key in a layout, a name for styling and finding the display text, and the function that implements the action.

Start/end keys:

.keypad-start, .keypad-end { background: #ff0; }
function moveCursor(input, pos) {
	if (input[0].setSelectionRange) { // Mozilla
		input[0].setSelectionRange(pos, pos);
	else if (input[0].createTextRange) { // IE
		var range = input[0].createTextRange();
		range.move('character', pos);;

$.keypad.addKeyDef('START', 'start',
	function(inst) { moveCursor(this, 0); });
$.keypad.addKeyDef('END', 'end',
	function(inst) { moveCursor(this, this.val().length); });

$('#startEndKeypad').keypad({prompt: '', keypadOnly: false,
	startText: '|<', startStatus: 'Move to start',
	endText: '>|', endStatus: 'Move to end',
	layout: ['789' + $.keypad.CLOSE,
		'456' + $.keypad.CLEAR,
		'123' + $.keypad.BACK,
		'.0' + $.keypad.SPACE + $.keypad.START + $.keypad.END]});
Callback Events

Callbacks notify you when certain events occur within the keypad. Of course, you can still have an onchange handler for the input field itself.

On key press: After the current value is

$('#pressKeypad').keypad({keypadOnly: false,
	onKeypress: function(key, value, inst) {
		$('#keypress').text(key || ' ');

On close:

$('#closeKeypad').keypad({keypadOnly: false,
	onClose: function(value, inst) {
		alert('Closed with value ' + value);

The beforeShow callback lets you update the keypad itself before it is shown. The keypad div and instance settings are passed as parameters.

Before show:

$('#showKeypad').keypad({keypadOnly: false,
	beforeShow: function(div, inst) {
		$('<button id="clickMe" class="keypad-key">Click me</button>').
			appendTo(div).click(function() { alert('Clicked'); });

You can localise the keypad for other languages. Select a language to change the text and tooltips.



You need to load the appropriate language package (see list below), which adds a language set ($.keypad.regionalOptions[langCode]) and automatically sets this language as the default for all keypad fields.

<script type="text/javascript" src="jquery.keypad-fr.js"></script>

Thereafter, if desired, you can restore the original language settings.


And then configure the language per keypad field.

$('#l10nKeypad').keypad($.extend({keypadClass: 'l10n'},

Or you can construct the complete keyboard for your language in the local format. The following layouts are defined in the specified localisations.


$('#l10nLayout').keypad($.extend({prompt: '',
	layout: $.keypad.azertyLayout}, $.keypad.regionalOptions['fr']));
$('#layoutSelect').change(function() {
	var details = $(this).val().split('|');
	localise(details[0], '#l10nLayout');
	$('#l10nLayout').keypad('option', {layout: $.keypad[details[1]]});
Keypad Styling

You can control the appearance of the keypad via CSS and the keypadClass option. The latter is set as a class value for the keypad instance, allowing it to be individually customised.

Flat green look:

$('#flatKeypad').keypad({keypadClass: 'flatKeypad',
	prompt: '', closeText: 'X', clearText: '<<', backText: '<'});
.keypad-popup.flatKeypad { background: #dfd; border: 1px solid #8c8;
	-moz-border-radius: 0.25em; -webkit-border-radius: 0.25em; }
.flatKeypad .keypad-key, .flatKeypad .keypad-special {
	width: 1.5em; border: 1px solid #8c8; -moz-border-radius: 0.25em;
	-webkit-border-radius: 0.25em; color: #000; background: #cfc; }
.flatKeypad .keypad-key-down { background: #8c8; }
.flatKeypad .keypad-clear { letter-spacing: -3px; text-align: left; }
.flatKeypad .keypad-space { width: 1.5em; }

Midnight buttons:

$('#midnightKeypad').keypad({keypadClass: 'midnightKeypad',
	prompt: '', closeText: 'X', clearText: '«', backText: '‹'});
.keypad-popup.midnightKeypad { background: #10085a; }
.midnightKeypad .keypad-key, .midnightKeypad .keypad-special {
	width: 38px; height: 38px; padding: 5px;
	background: url(img/midnight.gif) no-repeat; border: none;
	color: #fff; font-size: 1.5em; font-weight: bold; }
.midnightKeypad .keypad-key-down { padding: 7px 3px 3px 7px;
	background: url(img/midnight.gif) no-repeat -38px 0px; }
.midnightKeypad .keypad-space { width: 38px; height: 8px; }

Dark grey keyboard:

$('#darkKeypad').keypad({keypadClass: 'darkKeypad', keypadOnly: false,
	layout: $.keypad.qwertyLayout, prompt: ''});
.keypad-popup.darkKeypad { background: #333; }
.darkKeypad .keypad-key, .darkKeypad .keypad-special { width: 1.5em; background: transparent;
	color: #fff; border: 0.125em outset #fff; font-weight: bold; }
.darkKeypad .keypad-key-down { border: 0.125em inset #fff; }
.darkKeypad .keypad-shift, .darkKeypad .keypad-back,
.darkKeypad .keypad-clear, .darkKeypad .keypad-close,
.darkKeypad .keypad-enter { width: 3.25em; }
.darkKeypad .keypad-spacebar { width: 10.25em; }
.darkKeypad .keypad-space { width: 1.5em; }
.darkKeypad .keypad-half-space { width: 0.75em; }

Alternate native style:



$('#styleSelect').change(function() {
	$('#theme').attr('href', 'css/' + $(this).val());

To use ThemeRoller styling instead set the useThemeRoller option and include your favourite theme CSS.

ThemeRoller styling:


$('#themeRollerKeypad').keypad({useThemeRoller: true,
	keypadOnly: false, layout: $.keypad.qwertyLayout, prompt: 'Using ThemeRoller'});
$('#themeRollerSelect').change(function() {
	$('#themeUI').attr('href', 'themesDemo/' + $(this).val() + '/jquery-ui.css');

The snippet below shows the structure of the keypad along with the CSS classes you can target for customisation. The ui-* classes are only present if useThemeRoller is true.

<div class="keypadClass keypad-popup or keypad-inline ui-widget ui-widget-content">
	<div class="keypad-prompt ui-widget-header ui-corner-all">Extra characters</div>
	<div class="keypad-row">
		<button class="keypad-special keypad-close ui-state-default ui-state-highlight">Close</button>
		<button class="keypad-special keypad-clear ui-state-default ui-state-highlight">Clear</button>
		<button class="keypad-special keypad-back ui-state-default ui-state-highlight">Back</button>
	<div class="keypad-row">
		<button class="keypad-special keypad-shift ui-state-default ui-state-highlight">Shift</button>
		<div class="keypad-space"></div>
		<button class="keypad-key ui-state-default">â</button>
		<button class="keypad-key keypad-key-down ui-state-default ui-state-active">é</button>
	<div style="clear: both;"></div>

To change the overall size of the keypad just override the basic font size.

.keypad-popup, .keypad-inline, .keypad-key, .keypad-special { font-size: 20px; }
