<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>
