Make sure you include the appropriate extension script in the head (see the page head section above)

Autocomplete - integrate with jQuery UI Autocomplete

// target a specific keyboard, or use $('.ui-keyboard-input') to target all
  // keyboard plugin - see the full list of options above.
  // jQuery UI autocomplete - go to for a complete list of options
  // keyboard autocomplete extension, there are no options.

Typing - Simulate typing into the keyboard (tutorials or assist user input)

// Setup: targeting a specific keyboard, or use $('.ui-keyboard-input') to target all
// Usage: el.reveal().typeIn('text', time, callback);
// 'text' will be entered into the keyboard, time is the time in milliseconds between
// key strokes, the callback is called when completed.
// the following will type in the text with a 500ms delay then accept and close the keyboard when done.
var kb = $('#keyboard-input').getkeyboard();
  .typeIn('This is a test', 500, function(){ kb.accept(); });

Mobile - switch keyboard theme to match jQuery Mobile theme styles

// target a specific keyboard, or use $('.ui-keyboard-input') to target all
    keyBinding : 'mousedown touchstart',
    alwaysOpen : true,
    // make sure jQuery UI styles aren't applied even if the stylesheet has loaded
    // the Mobile UI theme will still over-ride the jQuery UI theme
    css : {
      input          : '',
      container      : '',
      buttonDefault  : '',
      buttonHover    : '',
      buttonActive   : '',
      buttonDisabled : ''
  // For a better idea of what the theme letters represent, try out the mobile demo, or
  // go directly to the jQuery Mobile theming overview page:
    // keyboard wrapper theme
    container    : { theme:'a' },
    // theme added to all regular buttons
    buttonMarkup : { theme:'a', shadow:'true', inline:'true', corners:'false' },
    // theme added to action buttons (e.g. tab, shift, accept, cancel);
    // parameters here will override the settings in the buttonMarkup
    buttonAction : { theme:'b' },
    // theme added to button when it is active (e.g. shift is down)
    // All extra parameters will be ignored
    buttonActive : { theme:'e' }

Navigation - Allows navigating the virtual keyboard using the arrow keys (use F1 to toggle the mode)

CSS needed to better highlight the action keys (shift, enter, accept, etc)

/* Add this css so we can see when the action (orange) keys are highlighted */
.ui-keyboard-button.ui-state-active.ui-state-hover {
  border: 1px solid #fff;
  -moz-box-shadow: 1px 1em 1px #ffba2b inset;
  -webkit-box-shadow: 1px 1em 1px #ffba2b inset;
  box-shadow: 1px 1em 1px #ffba2b inset;
/* Class added to indicate the virtual keyboard has navigation focus */
.hasFocus {
  border-color: #59b4d4;


    position   : [0,0],     // set start position [row-number, key-index]
    toggleMode : false,     // true = navigate the virtual keyboard, false = navigate in input/textarea
    toggleKey  : 112,       // toggle key; F1 = 112 (event.which value for function 1 key)
    focusClass : 'hasFocus' // css class added to the keyboard when toggle mode is on


Scramble targeted keyboard keys by row or entire keyset.

// target a specific keyboard, or use $('.ui-keyboard-input') to target all
  // keyboard plugin - see the full list of options above.
    targetKeys    : /[a-z\d]/i, // keys to randomize
    byRow         : true,       // randomize by row, otherwise randomize all keys
    randomizeOnce : true        // if true, randomize only once on keyboard visible
