Create AN On-screen DVORAK Keyboard using jQuery and CSS

Makes use of jQuery, CSS and plain Html to create a DVORAK keyboard that works with textarea and input filed.

How to use it:

1. Create a textarea element to accept user input.

<textarea id="write" rows="6" cols="60"></textarea>

2. Build the html structure for the DVORAK keyboard using html unordered list.

<ul id="keyboard">
  <li class="symbol"><span class="off">`</span><span class="on">~</span></li>
  <li class="symbol"><span class="off">1</span><span class="on">!</span></li>
  <li class="symbol"><span class="off">2</span><span class="on">@</span></li>
  <li class="symbol"><span class="off">3</span><span class="on">#</span></li>
  <li class="symbol"><span class="off">4</span><span class="on">$</span></li>
  <li class="symbol"><span class="off">5</span><span class="on">%</span></li>
  <li class="symbol"><span class="off">6</span><span class="on">^</span></li>
  <li class="symbol"><span class="off">7</span><span class="on">&amp;</span></li>
  <li class="symbol"><span class="off">8</span><span class="on">*</span></li>
  <li class="symbol"><span class="off">9</span><span class="on">(</span></li>
  <li class="symbol"><span class="off">0</span><span class="on">)</span></li>
  <li class="symbol"><span class="off">[</span><span class="on">{</span></li>
  <li class="symbol"><span class="off">]</span><span class="on">}</span></li>
  <li class="delete lastitem">delete</li>
  <li class="tab">tab</li>
  <li class="symbol"><span class="off">'</span><span class="on">&quot;</span></li>
  <li class="symbol"><span class="off">,</span><span class="on">&lt;</span></li>
  <li class="symbol"><span class="off">.</span><span class="on">&gt;</span></li>
  <li class="letter">p</li>
  <li class="letter">y</li>
  <li class="letter">f</li>
  <li class="letter">g</li>
  <li class="letter">c</li>
  <li class="letter">r</li>
  <li class="letter">l</li>
  <li class="symbol"><span class="off">/</span><span class="on">?</span></li>
  <li class="symbol"><span class="off">=</span><span class="on">+</span></li>
  <li class="symbol lastitem"><span class="off">\</span><span class="on">|</span></li>
  <li class="capslock">caps lock</li>
  <li class="letter">a</li>
  <li class="letter">o</li>

  <li class="letter">n</li>
  <li class="letter">s</li>
  <li class="symbol"><span class="off">-</span><span class="on">_</span></li>
  <li class="return lastitem">return</li>
  <li class="left-shift">shift</li>
  <li class="symbol"><span class="off">;</span><span class="on">:</span></li>
  <li class="letter">q</li>
  <li class="letter">j</li>
  <li class="letter">k</li>
  <li class="letter">x</li>
  <li class="letter">b</li>
  <li class="letter">m</li>
  <li class="letter">w</li>
  <li class="letter">v</li>
  <li class="letter">z</li>
  <li class="right-shift lastitem">shift</li>
  <li class="space lastitem">&nbsp;</li>
</ul>

3. The required CSS styles.

#write {
  margin: 0 0 5px;
  padding: 5px;
  width: 671px;
  height: 200px;
  font: 1em/1.5 Verdana, Sans-Serif;
  background: #fff;
  border: 2px solid #000000;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
}

#keyboard {
  margin: 0;
  padding: 0;
  list-style: none;
}

#keyboard li {
  float: left;
  margin: 0 5px 5px 0;
  width: 40px;
  height: 40px;
  line-height: 40px;
  text-align: center;
  background: #fff;
  border: 1px solid #000000;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
  -webkit-box-shadow: 0px 1px 3px #000000;
}

.capslock, .tab, .left-shift { clear: left; }

#keyboard .tab, #keyboard .delete { width: 70px; }

#keyboard .capslock { width: 80px; }

#keyboard .return { width: 77px; }

#keyboard .left-shift { width: 95px; }

#keyboard .right-shift { width: 109px; }

.lastitem { margin-right: 0; }

.uppercase { text-transform: uppercase; }

#keyboard .space {
  clear: left;
  width: 681px;
}

.on { display: none; }

#keyboard li:hover {
  position: relative;
  top: 2px;
  left: 2px;
  border-color: #000000;
  background: #00BFFF;
  cursor: pointer;
  color: #ffffff;
}

4. Include the latest version of jQuery library on the web page.

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>

5. The core JavaScript to active the DVORAK keyboard.

$(function(){
  var $write = $('#write'),
    shift = false,
    capslock = false;

  $('#keyboard li').click(function(){
    var $this = $(this),
      character = $this.html(); // If it's a lowercase letter, nothing happens to this variable

    // Shift keys
    if ($this.hasClass('left-shift') || $this.hasClass('right-shift')) {
      $('.letter').toggleClass('uppercase');
      $('.symbol span').toggle();

      shift = (shift === true) ? false : true;
      capslock = false;
      return false;
    }

    // Caps lock
    if ($this.hasClass('capslock')) {
      $('.letter').toggleClass('uppercase');
      capslock = true;
      return false;
    }

    // Delete
    if ($this.hasClass('delete')) {
      var html = $write.val();

      $write.val(html.substr(0, html.length - 1));
      return false;
    }

    // Special characters
    if ($this.hasClass('symbol')) character = $('span:visible', $this).html();
    if ($this.hasClass('space')) character = ' ';
    if ($this.hasClass('tab')) character = "\t";
    if ($this.hasClass('return')) character = "\n";

    // Uppercase letter
    if ($this.hasClass('uppercase')) character = character.toUpperCase();

    // Remove shift once a key is clicked.
    if (shift === true) {
      $('.symbol span').toggle();
      if (capslock === false) $('.letter').toggleClass('uppercase');

      shift = false;
    }
    console.log("DO IT ", character);
    // Add the character
    $write.val($write.val() + character);
  });
});
