如何转换基于IE浏览器的Msxml2.XMLHTTP网站,以便它也适用于Firefox？

Ho1*_*Ho1 6 javascript xmlhttprequest cross-browser

这是一个仅限IE的网站,我想与其他浏览器一起使用,例如Firefox:

https://golestan.sbu.ac.ir/Forms/AuthenticateUser/login.htm

我被迫将这个网站用于我的大学.它使用Msxml2.XMLHTTP,这是一个仅限IE的功能.我试图将其转换为XMLHttpRequest仅适用于Firefox.这是我创建的Greasemonkey脚本.现在它没有给出错误,但它不起作用.所有功能都来自网站的原始脚本,但它们会被更改以便它们可以使用XMLHttpRequest.如果登录脚本出现,我很好.我该如何调试这个javascript？

我认为这项工作值得做,因为数百名大学生用户受到了影响.

更新:我们可以更进一步,达到目标main.htm.所以,我为这个页面编写了另一个脚本.但是,最后我得到了ReferenceError: element is not defined[Learn More].

需要注意的事项

\n\n

xhr(async:false)HEAD 请求中使用的站点。哪个已弃用

\n\n

您可以在这里阅读更多相关信息https://xhr.spec.whatwg.org/

\n\n

主要的说法是

\n\n

\n
工作人员之外的同步 XMLHttpRequest 正在从 Web 平台中删除，因为它对最终用户\xe2\x80\x99s 体验产生不利影响。（这是一个漫长的过程，需要很多年。）当当前全局对象是 Window 对象时，开发人员不得为 async 参数传递 false。强烈建议用户代理在开发人员工具中对此类使用发出警告，并在发生这种情况时尝试抛出 InvalidAccessError 异常。
\n

\n\n

所以，将其更改为true.

\n\n

然后使用@run-at document-end.

\n\n

我创建了一个可以为您完成这项工作的脚本。

\n\n

我使用的方法，

\n\n

从站点复制整个脚本代码并进行必要的更改。

\n\n

在用户脚本中，删除脚本元素并将更改后的脚本注入到网页中。

\n\n

它将改变页面，如下所示。但似乎来自服务器的所有 td 元素都是空的。

\n\n

您可以在这里看到网络传输

\n\n

这是用户脚本
