The js syntax of the IE web page is incorrect. 2 lines of characters, 1 character, and FF are normal.

During the development process today, I suddenly encountered this strange problem. I previously thought that there was a problem with the url parameter passed when I opened the modal form in js. it was okay if I used open. When using the modal form, this error is displayed first and then a new interface is displayed. The solution is summarized as follows: 1. Some plug-ins may conflict with IE. Disable all irrelevant IE add-ons and try again. references a nonexistent js file 3. some files on the page have started to reference relevant nodes before the document model is created. I finally solved this problem by disabling the plug-in IE.
