The javascript.vim that highlights javascript in vim has been put into syntax, but it doesn't work.

Question

As shown in the picture, part of it is highlighted, and some DOM attributes are not highlighted. Is this the reason?

Do I need to set anything in .vimrc?

Answer 1

.vimrc 加入以下3句：
syntax enable " enable syntax hightlight and completion
syntax on " syntax highlighing
filetype on " try to detect file types

Answer 2

js highlighting (including js embedded in html, including independent js files), only uses a plug-in. https://github.com/pangloss/vim-javas...

Answer 3

VIM’s default js syntax highlighting is quite unsatisfactory. You can find a better one online. However, I don’t recommend using too many plugins. Just take a look. However, it is recommended that you highlight the highlights, various parentheses, and various symbols, because these are the real delimiters in the code.
