如何使用jquery将无序列表转换为<select>下拉列表？

Question

如何在这个格式转换的无序列表

<ul class="selectdropdown"> 
 
    <li><a href="one.html" target="_blank">one</a></li> 
 
    <li><a href="two.html" target="_blank">two</a></li> 
 
    <ul> 
 
     <li><a href="twoOne.html" target="_blank">two One</a></li> 
 
     <ul> 
 
      <li><a href="twoOneOne.html" target="_blank">two One One</a></li> 
 
     </ul> 
 
     <li><a href="twoTwo.html" target="_blank">twoTwo</a></li> 
 
    </ul> 
 
    <li><a href="three.html" target="_blank">three</a></li> 
 
    <li><a href="four.html" target="_blank">four</a></li> 
 
    <li><a href="five.html" target="_blank">five</a></li> 
 
    <li><a href="six.html" target="_blank">six</a></li> 
 
    <li><a href="seven.html" target="_blank">seven</a></li> 
 
</ul>

我想这种结构转换成<select>结构

Answer 1

jQuery代码

jQuery('.selectdropdown li a').each(function() { 
     var el = jQuery(this); 
     jQuery('<option />', { 
      "value" : el.attr('href'), 
      "text" : el.text() 
     }).appendTo('#top select'); 
    }); 
    if (jQuery('.selectdropdown li a').length < 1) jQuery('#top').hide(); 

    jQuery('#top').find('select').change(function() { 
     window.location = jQuery(this).find('option:selected').val(); 
    }); 

HTML

<div id="top"> 
<select></select> 
</div>
