How to implement route jump recording function with Vue Router and Vue.js

Routing is an important concept when developing web applications using Vue.js. Vue Router is the official router library for Vue.js, which allows us to control application navigation through URLs. Vue Router provides a set of APIs to manage application routing, including navigation, parameter passing, routing status, etc. But in actual development, we often need to record the user's routing jump record in the application, such as recording which pages the user visited, the user's scroll position in the page, etc. This article will introduce how to use Vue Router and Vue.js global navigation guard to implement route jump recording function.

1. Use Vue Router to record routing jump history

Vue Router provides a routing history object (history), through which we can obtain the current routing status. And routing jumps can be achieved through push, replace and other methods. We can record the routing jump history by listening to the events of the routing object. For example, we can record the routing jump history in the beforeEach method of the routing object. The sample code is as follows:

const router = new VueRouter({ routes: [ // 路由定义 ] }); router.beforeEach((to, from, next) => { // to 和 from 都是路由对象 // 记录路由跳转历史 // ... next(); });

In the above code, the beforeEach method is Vue A global navigation guard function provided by Router, which will be called before the route jumps. We can record the user's routing jump history in this method. In the sample code, we can use the to and from parameters to obtain the current routing object and the previous routing object, and then record them to an array or store them locally. Store (Local Storage) for subsequent query.

2. Use Vue.js global navigation guard to record route jumps

In addition to recording route jump history in Vue Router, we can also use Vue.js to provide The global navigation guard function is used to implement the recording of route jumps. Vue.js provides three global navigation guard functions: beforeEach, beforeResolve and afterEach. They are called before route jump, before route resolution and after route jump respectively. We can record route jump history in these navigation guard functions. The sample code is as follows:

const router = new VueRouter({ routes: [ // 路由定义 ] }); router.beforeEach((to, from, next) => { // 记录路由跳转历史 // ... next(); }); Vue.mixin({ beforeRouteLeave (to, from, next) { // 记录路由跳转历史 // ... next(); } });

In the above code, we use the Vue.mixin method to add the global navigation guard function to the Vue component. In the beforeRouteLeave function, we can record the user's route jump history. This function will be called when the component is about to leave the current route. We can record route jump history into an array or local storage.

Summary:

This article introduces how to use Vue Router and Vue.js global navigation guard to record the user's route jump history. In actual development, we can choose which method to use to record routing jump history according to specific needs. For example, we can use Vue Router to record the user's access history, and use Vue.js global navigation guard to record the jumps of some special events. Turn to history. Routing jump history is a common requirement. When implementing it, you need to pay attention to issues such as performance issues and storage capacity.
