Problems after the launch of vue

none of the local tests have appeared

but there is a canot read property "tagName" of null

in production.

but I search in the code and there is no tagName variable

give it a try and this prompt appears as soon as I click on the page

what is commonly used is that element plug-ins are referenced directly when they are not loaded on demand

I don"t know why, but I think it has something to do with element, because the search creates some dom

.

but I don"t know how to solve this problem

em... It seems that the browser"s own problem is that the click error is located in the Doctype html line
, and if I only open Baidu, this error will occur. Other people"s computers will not show this

this has nothing to do with vue. Where or which plug-in needs to get tagName before reporting an error


check whether your online code has this variable


first of all, what caused this mistake? And then where did it happen? Generally speaking, you can only locate the problem.
