IE web page js syntax error 2 lines of characters 1, normal solution in FF_Basic knowledge

During the development process today, I suddenly encountered this strange problem. I thought it was a problem with the url parameters passed by my js to open the modal form. I used open and there was no problem. If you use a modal form, this error will pop up first and then the newly opened interface will be displayed. After searching online for a long time, the solutions are summarized as follows:

1. It may conflict with some plug-ins of IE. Please try after disabling all irrelevant IE add-ons

2. Reference to non-existent js files

3. Some files on the page have been started before the document model has been established. Quote relevant nodes

I finally solved the problem by disabling the plug-in in IE.
