推荐答案

有可能-如果不包含文件，则$变量确实不是预期的对象. 预期对象"错误通常表示您拥有一个null/undefined变量，然后尝试在其上调用方法.

It's possible - if the files weren't included, then the $ variable would indeed not be an object where one was expected. "Object expected" errors usually mean that you have a variable that is null/undefined and then try to call methods on it.

我会尝试使用简单的alert($);来确定是否是这种情况，并查看结果是undefined(不好)还是其他(可能是好的).

I'd try to find out if this is the case with a simple alert($); and see whether the result is undefined (bad) or something else (probably good).
