Component reuse of different routes

1 scene restore

When vue-router is from / post-page/an in a scene, jump to / post-page/b. Then we were surprised to find that the data was not updated after the page jumped. The reason is that vue-router "intelligently" discovers that this is the same component, and then it decides to reuse the component, so the method you wrote in the created function is not executed at all. The usual solution is to listen for changes in $route to initialize the data, as follows:

Data () {return {loading: false, error: null, post: null}}, watch: {'$route': {/ / use watch to monitor whether it is the same route handler: 'resetData', immediate: true}}, methods: {resetData () {this.loading = false this.error = null this.post = null this.getPost (this.$route.params.id)}, getPost (id) {}}

2 optimization

So how can we achieve this effect? the answer is to add a different key to router-view, so that even if it is a common component, as soon as the url changes, it will be recreated.

You can also add a + + new Date () timestamp after it to ensure uniqueness.
