Vue routing this.route.push jump page does not refresh I. background

Introduction: in vue project development, when routing is used for page jump, the page to which the route is redirected will not be refreshed.

That is, vue lifecycle functions are not executed (created, mounted hook functions).

Case study:

A page:

Page B:

Question:

When you first click the button on page A to page B, everything is fine. When you return to page An and click the button again, page B does not execute the mounted hook function. As a result, the query method in the mounted function is not executed.

2. Solution:

1. Use the activated: {} periodic function instead of the mounted: {} function.

2. Listen for routing

/ / not recommended, poor user experience watch: {'$route' (to, from) {/ / routing changes page refresh this.$router.go (0) }}, / / this method will request watch: {'$route' (to, from) {/ / the method executed in the mounted function, put there this.qBankId = globalVariable.questionBankId; this.qBankName = globalVariable.questionBankTitle; this.searchCharpter () }}, Vue this.$router.push route jumps, refresh parameter disappears this.$router.push ({name: ", params: {id:"}})

Refresh parameters will disappear with name and params.

This.$router.push ({path: ", query: {id:"}})

When path and query are matched, the refresh page parameters will not disappear, and the parameters in query become part of url.
