这是一个仅限 IE 的网站，我想将其与其他浏览器一起使用，例如 Firefox:
https://golestan.sbu.ac.ir/Forms/AuthenticateUser/login.htm
我被迫为我的大学使用这个网站。它使用 Msxml2.XMLHTTP，这是 IE 独有的功能。我尝试将其转换为 XMLHttpRequest，因此它仅适用于 Firefox。这是我创建的 Greasemonkey 脚本。现在它不报错，但它不起作用。
所有功能均来自网站的原始脚本，但经过更改以便与 XMLHttpRequest 一起使用。
如果出现登录脚本，我可以接受。我该如何调试这个 javascript？

我认为这项工作是值得做的，因为数十万的大学生用户受到影响。
更新:我们可以更进一步，到达 main.htm。所以，我为这个页面写了另一个脚本。但是，最后我得到了 ReferenceError: element is not defined[了解更多]。

注意事项
站点在 HEAD 请求中使用了 xhr(async:false)。哪个被弃用了
您可以在此处阅读更多相关信息 https://xhr.spec.whatwg.org/
主要说法是
Synchronous XMLHttpRequest outside of workers is in the process of being removed from the web platform as it has detrimental effects to the end user’s experience. (This is a long process that takes many years.) Developers must not pass false for the async argument when current global object is a Window object. User agents are strongly encouraged to warn about such usage in developer tools and may experiment with throwing an InvalidAccessError exception when it occurs.
因此，将其更改为 true。
然后使用@run-at document-end。
我创建了一个脚本来为您完成这项工作。
我使用的方法，
从站点复制了整个脚本代码并进行了必要的更改。
在用户脚本中，删除脚本元素并将更改后的脚本注入(inject)网页。
它将改变页面，如下所示。但是似乎所有来自服务器的 td 元素都是空的。
这里可以看到网络传输
这是用户脚本
