rt: ie8 compatibility issue
There is no problem using the jquery-form plug-in to upload files on native ie8 or upgrade from a low version of ie (ie6) to ie8, but after downgrading to a high version of ie (ie11) to ie8 It's not easy to use. The F12 console doesn't report an error, and I can't debug it. It's really frustrating! Has anyone encountered this weird problem?
Restart the computer. After restarting, check if there are IE upgrade patches that have not been deleted
