How to deal with vue-router3.0 version router.push unable to refresh the page

This time I will bring you how to deal with the vue-router3.0 version router.push that cannot refresh the page. What are the things to note when dealing with the vue-router3.0 version router.push that cannot refresh the page? What are the following? This is a practical case, let’s take a look at it.

Yesterday I found that some

routes could not jump normally. After searching, I found that they were all those places where router.push was used after instantiation instead of using this.$router.push directly. What happens is that after router.push, the url changes, but the page does not refresh. You need to refresh it manually before the proper screen appears.

I took a look at package.json. My vue and axios did not write the version number, but vue-router clearly wrote the version number. How could it be possible that it worked before but not now?

Then, I used npm view vue-router to check and found that the version I was using was no longer the version in package.json, so I concluded that maybe it was my npm up

date a few days ago!

(Don’t update casually in the future!)

I don’t know exactly why the new version doesn’t work.

The simplest solution is of course to directly change router.push to this.$router.push

But, if this is possible, why should I instantiate another one in the component in the first place? What about Router?

Obviously because this is not vue in some places, then, is it okay to instantiate a vue and then use vue.$router?

The answer is of course no, because this vue and the vue in

other places should not be the same object.

Then, the ultimate solution is:

Add the router in the global vue to the window, and use it in main.js:

Then other You can happily use router.push and other router methods anywhere.

Analysis reason:

The router after the instance cannot refresh the page, probably because it is not the same as this.$router in the global vue, and before In the version, it can be used directly like this, it should be using a singleton.

As for why we don’t use singletons anymore, how do I know this?
