When I open my page, I get error: $.document is null. Why? Secondly, is there any way to determine from which path the below given code is loading the file "filevalues.php"?

推荐答案

首先，没有<$ code> $。文件。我认为你的意思是 $（文件），因为那是你的代码所说的......？

First of all, there's no such thing as $.document. I take it you mean $(document), since that's what your code says...?

如果 $（document）不起作用，你的jQuery库没有正确加载，或者与覆盖 $的值的其他内容冲突。如果 jQuery（文档）也不起作用，那么问题就是前者。

If $(document) doesn't work, your jQuery library isn't being loaded correctly, or it's in conflict with something else that overwrites the value of $. If jQuery(document) also isn't working, then the problem is the former.

Firefox的Firebug是一个非常好的工具来追查这样的问题。您可以重新加载页面并查看正在生成的jquery js文件的请求，查看它正在请求的确切路径，以及它在响应中收到的确切内容。

Firefox's Firebug is a very good tool to trace down issues like that. You can reload the page and see the request for the jquery js file being made, see exactly what path it is requesting, and exactly what it receives in response.
