推荐答案

就像尼克所说，您可能不包括jQuery，Firebug是否有任何错误或类似的东西?

Like Nick said, you probably aren't including jQuery, are there any errors in Firebug or anything like that?

此外，您可能需要考虑将更多的switch替换为更多类似的内容:

Also, you might want to consider replacing most of your huge switch with something more like:

content.slideUp();
content.load("http://tdr.host22.com/sections.html #" + this.id + "_section", hideLoading);
content.slideDown();

为了更清楚地了解这最后一部分，请首先进入标记并进行更改:

To be more clear about this last part, first go into your markup and change:

<li><a id="about">About Me</a></li>

进入

<li><a id="aboutme">About Me</a></li>

这是因为在您的javascript中，您正在显示一个名为"aboutme"的部分……最好保持名称匹配....然后删除整个switch并替换为:

This is because in your javascript you're showing a section called 'aboutme'... best to just keep the names matching.... then delete your entire switch and replace it with:

content.slideUp();
content.load("http://tdr.host22.com/sections.html #" + this.id + "_section", hideLoading);
content.slideDown();

因此，您代码的整个javascript部分(进行了一些其他改进)成为了

So the entire javascript portion of your code becomes (with some other improvements):

$(document).ready( function() {
  var sections = $("#menu a");
  var loading = $("#loading");
  var content = $("#content");

  function showLoading() {
    loading.css( {
      visibility: 'visible',
      opacity: 1,
      display: 'block'
    } );
  }

  function hideLoading(){
    loading.fadeTo(1000, 0);
  }

  sections.click( function() {
    showLoading();
    content.slideUp();
    content.load("http://tdr.host22.com/sections.html #" + this.id + "_section", hideLoading);
    content.slideDown();
  } );
} );

如您所见，此代码非常简短，因此甚至不需要注释.

As you can see, this code doesn't even need comments because it's so short and concise.

此外，通读此书，似乎几乎可以肯定还有其他问题...动画不会按照您期望的方式发生，slideUp是异步的，这意味着它将开始滑动然后立即加载，您可能没有不需要这种行为，因此请研究jQuery的链接动画的方法(通过回调，请参见 slideUp )，或看看jQuery 1.4的 delay 方法

Also, reading through this, it seems you almost certainly have other problems... The animations wont happen the way you expect, slideUp is asynchronous meaning that it will start sliding up and then immediately load, you probably don't want this behavior so look into jQuery's method of chaining animations (via callbacks, see the docs for slideUp, for example), or take a look at jQuery 1.4's delay method.
