JQuery Virtual Keyboard

A quick post on virtual keyboard which can be used to enter user name / password / Pine number, etc… Internet banking highly recommend to use while logging into Internet Banking Site.

Below are the advantages of virtual keyboard

  • The virtual keyboard can be an additional precautionary measure, protects you against malicious key logger programs which might have infected your  computer.
  • A key logger program can capture the keystrokes you enter in the physical keyboard to login which may be accessing your PC without your knowledge or permission.
  • A virtual keyboard prevents your username or password from being stolen, especially while using public computers, such as those available in Internet cafes. Also, the sequence in which the keys appear will change everytime the page is refreshed.

Before I start with an example go through Keith Wood’s solution for it build on top of JQuery

Step 0:- Create Folder structure as below

  • main
  • main/css
  • main/javascript

Step 1:-  Add jquery.keypad.css in main/css folder

Step 2:-  Add jquery-1.7.1.min.js and jquery.keypad.js in main/javascript folder

Step 3:-  Add index.html in main folder and copy-paste below code into index.html  “please read code carefully before copying it blindly :D”

<title>Virtual Keyboard</title>
 <link type="text/css" href="css/jquery.keypad.css" rel="stylesheet" />  
 <script type="text/javascript" src="javascript/jquery-1.7.1.min.js"></script>
 <script type="text/javascript" src="javascript/jquery.keypad.js"></script> 
    <script type="text/javascript">
        $(document).ready(function () {                    
            $("input[id$='chkKeyboard']").click(function () {            
                if (!$(this).is(':checked')) {
                } else {
                    $('#txtUsername').keypad({ keypadOnly: true, layout: $.keypad.qwertyLayout, randomiseAlphabetic: true, randomiseNumeric: true, randomiseOther: true });
                    $('#txtPassword').keypad({ keypadOnly: true, layout: $.keypad.qwertyLayout, randomiseAlphabetic: true, randomiseNumeric: true, randomiseOther: true });                    


   <div style="text-align: left; margin-top: 15px;">                           
      Username : <input type="text" id="txtUsername" /><br/>
      Password : <input type="Password" id="txtPassword"></asp:TextBox><br/>
      <input type="checkbox" id="chkKeyboard" /> Use virtual keyboard (Recommended)<br/>
