 <h2>iPhone风格的单选框和复选框jQuery代码</h2>
 <h4>From DevGrow, a blog about designing, developing and growing your website.</h4>
 <h3>The Example:</h3>
 <p class="field switch">
  <input type="radio" id="radio1" name="field" checked />enable
  <input type="radio" id="radio2" name="field" />disable
  <label for="radio1" class="cb-enable selected"><span>Enable</span></label>
  <label for="radio2" class="cb-disable"><span>Disable</span></label>
 </p>
 <p class="field switch">
  <label class="cb-enable"><span>On</span></label>
  <label class="cb-disable selected"><span>Off</span></label>
  <input type="checkbox" id="checkbox" class="checkbox" name="field2" /> Checkbox
 </p>
<h3>The Prerequisites</h3>
 <p>You need just two things for this to work correctly: JQuery 1.3.2+ and the images/switch.gif image file used for the backgrounds.</p>
<h3><span>Step 1</span> The HTML</h3>
 <pre><code>
 <p class="field switch">
  <input type="radio" id="radio1" name="field" checked />
  <input type="radio" id="radio2" name="field" />
  <label for="radio1" class="cb-enable selected">>span>Enable</span></label>
  <label for="radio2" class="cb-disable"><span>Disable</span></label>
 </p>
 <p class="field switch">
  <label class="cb-enable"><span>On</span></label>
  <label class="cb-disable selected"><span>Off</span></label>
  <input type="checkbox" id="checkbox" class="checkbox" name="field2" />
 </p>
 </code>
 </pre>
 <h3><span>Step 2</span> The Javascript</h3>
 <pre><code>
 $(document).ready( function(){
  $(".cb-enable").click(function(){
   var parent = $(this).parents('.switch');
   $('.cb-disable',parent).removeClass('selected');
   $(this).addClass('selected');
   $('.checkbox',parent).attr('checked', true);
  });
  $(".cb-disable").click(function(){
   var parent = $(this).parents('.switch');
   $('.cb-enable',parent).removeClass('selected');
   $(this).addClass('selected');
   $('.checkbox',parent).attr('checked', false);
  });
 });</code>
 </pre>
 <h3><span>Step 3</span> The CSS</h3>
 <pre><code>
 .cb-enable, .cb-disable, .cb-enable span, .cb-disable span { background: url(switch.gif) repeat-x; display: block; float: left; }
 .cb-enable span, .cb-disable span { line-height: 30px; display: block; background-repeat: no-repeat; font-weight: bold; }
 .cb-enable span { background-position: left -90px; padding: 0 10px; }
 .cb-disable span { background-position: right -180px;padding: 0 10px; }
 .cb-disable.selected { background-position: 0 -30px; }
 .cb-disable.selected span { background-position: right -210px; color: #fff; }
 .cb-enable.selected { background-position: 0 -60px; }
 .cb-enable.selected span { background-position: left -150px; color: #fff; }
 .switch label { cursor: pointer; }
 .switch input { display: none; }</code>
 </pre>
 <h3>Compatability</h3>
 <p>While this should work in all major browsers, it has only been tested on: Firefox 3.5+, IE7+, Chrome 4.1+, Opera 9.6+, Safari 4+</p>
