javascript - 可以 .slideToggle() 特定的 <li> 吗？

Question

有一个<ul>导航链接。一项特别<li>实际上变成了3个链接。想要那个特别的<li>滑动打开和关闭以显示其他三个链接。

<ul id="courseLinks">
    <li><a href="#"><strong>Week 1</strong> introduction</a></li>
    <li><a href="./homework/week2/week2homework.htm"><strong>Week 2</strong> dev tools + standards</a></li>
    <li><a href="./homework/week3/week3homework.htm"><strong>Week 3</strong> HTML 5 &amp; SEO</a></li>
    <li><a href="#" id="homeworkSlide"><strong>Week 4</strong> css concepts</a></li>
    <li id="slider"><a href="homework/week4/exercise1.htm">Exercise 1</a>
            <a href="homework/week4/exercise2.htm">Exercise 2</a>
            <a href="homework/week4/week4homework.htm">Homework</a></li>
    <li><a href="#"><strong>Week 5</strong> advanced css</a></li>
    <li><a href="#"><strong>Week 6</strong> server side includes</a></li>
    <li><a href="#"><strong>Week 7</strong> site construction</a></li>
    <li><a href="#"><strong>Week 8</strong> development methodology 1</a></li>
    <li><a href="#"><strong>Week 9</strong> user experience</a></li>
    <li><a href="#"><strong>Week 10</strong> social software</a></li>
    <li><a href="#"><strong>Week 11</strong> project work</a></li>
    <li><a href="#"><strong>Week 12</strong> final examination</a></li>
</ul><!--nav-->

Jquery:

$('#homeworkSlide').click(function() {
  $('#slider').slideToggle('slow', function() {
    // Animation complete.
  });
});

拒绝工作。自学javascript至此，是不是可以修改了<ul>以这种方式？还是我做错了什么？

Answer 1

我已阅读您的 host 上的源代码，发现绑定(bind)操作没有绑定(bind)在$(document).ready(...)中，可能就是这个原因。

所以，修改代码。

$(document).ready( function() { 
    $('#homeworkSlide').click(function() {
      $('#slider').slideToggle('slow', function() {
        // Animation complete.
      });
    });
} );
