Answer 1

您需要包含jQuery库。

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>

Answer 2

您没有包含jQuery库本身：

<script src="jquery.min.js" type="text/javascript">
</script>

您还可以从CDN

中添加它

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"
  type="text/javascript"></script>

Answer 3

尽管我对这个问题有所评论，但看起来主要的罪魁祸首是你实际上并没有引用jQuery JS文件。尝试类似：

<script type="text/javascript" src="Scripts/jquery-1.3.2.js"></script>

我的jQuery不起作用
