Internet Explorer caused by Ajax cannot open an Internet site

Debug extjs in Firefox. Everything is OK. When I ran to IE for testing, "Internet Explorer cannot open the Internet site" appeared, which is equivalent to "fail. Basically, it is caused by Ajax. when the document is not loaded, the gray such as appendchild or innerhtml is called, which causes the IE parsing to fail, but the changes are huge, after n times of elimination, the problem was finally solved-because the show and hide methods of ext windows were called when the document was not loaded, which is quite fragile.

 

In contrast, Firefox provides good support for Ajax. However, Firefox's cache mechanism is a bit confusing. After half a day, it was installed with a cache status plug-in to clear the cache. It seems that sometimes it is useless, finally, you can clear the cache by checking "tool-> Option-> advanced-> clear now.

In addition, you can add <meta http-equiv = "cache-control" content = "no-store"> in HTML to disable Firefox from caching the HTML page.
