Answer 1

正如 Nick 所说，您可能没有包括 jQuery，Firebug 中是否有任何错误或类似的错误？

此外，您可能需要考虑将大部分巨大的 switch 替换为更类似的东西:

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

编辑:为了更清楚地了解最后一部分，首先进入您的标记并更改:

<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，您显示了一个名为“aboutme”的部分...最好只保持名称匹配...然后删除整个 switch 并将其替换为:

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

所以你的代码的整个 javascript 部分变成了(有一些其他的改进):

$(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，这段代码甚至不需要注释，因为它非常简短。

此外，通读本文，似乎您几乎肯定还有其他问题...动画不会按您预期的方式发生，slideUp 是异步的，这意味着它将开始向上滑动然后立即加载，您可能不希望出现这种行为，因此请查看 jQuery 的链接动画方法(例如，通过回调，请参阅 slideUp 的文档)，或者查看 jQuery 1.4 的 delay。方法。
