如何选择下拉值？每当我在xsl的下拉列表中选择一些值时，我都试图显示一些数据。例如，如果在下拉列表中选择了A，则与A相关的详细信息将显示在表格中。同样，如果选择B，则仅显示与B相关的详细信息。我需要在xslt中编写一行代码来选择if语句中的下拉值。

如果要在浏览器中使用客户端XSLT从XML数据构建HTML页面，请注意XSLT只能定义转换过程。当HTML准备就绪时，XSLT已经完成了它的工作。你可以做的是将javascript插入XSLT源，它对下拉变化做出反应并隐藏不合适的数据。 XSLT无法与Javascript通信，因为Javascript将在页面完成并且XSLT已经完成后开始工作。但它可以使javascript适合HTML源代码。想象一下如何在没有XSLT的普通HTML中解决这个问题，让XSLT构建这个HTML。
