我的网页上有一个选择框,当我选择一个值时,它应该添加另一个选择框,如果我在第二个选择框中选择一个值,我需要添加第三个选择框 这是我的代码

<script type="text/javascript">//<![CDATA[
$(function() {
$('#colorselector').change(function(){
$('.colors').hide();
$('#' + $(this).val()).show();
});
});
//]]>
</script>
</head>
<body>
<select id="colorselector">
<option value="red">Red</option>
<option value="yellow">Yellow</option>
</select>
<div id="red" class="colors" style="display:none"> <select id="colorselector">
<option value="one">one</option>
<option value="two">two</option>
<option value="three">three</option>
</select> </div>
<div id="yellow" class="colors" style="display:none">
<select id="colorselector">
<option value="one">one</option>
<option value="two">two</option>
<option value="three">three</option>
</select>
</div>
<div id="one" class="colors" style="display:none"> one... </div>
<div id="two" class="colors" style="display:none">
<select id="colorselector">
<option value="one">four</option>
<option value="two">five</option>
<option value="three">six</option>

</div>
</body>
</html>
