This is simple jQuery on screen keyboard.

usage:

<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="jkeyboard.js"></script>
<link rel="stylesheet" href="jkeyboard.css">

<input type="text" id="search_field">
<div id="keyboard"></div>


$('#keyboard').jkeyboard({
  layout: "english",
  input: $('#search_field')
});

Click to view in action

for now new layouts can be added on jkeyboard.js, I'm working on basic api.

Example layout for russian:

russian: [
    ['й','ц','у','к','е','н','г','ш','щ','з', 'х' ],
    ['ф','ы','в','а','п','р','о','л','д','ж', 'э' ],
    ['shift','я','ч','с','м','и','т','ь','б','ю', 'backspace'],
    ['numeric_switch','layout_switch', 'space','return']
],
