Vue customizes the menu bar and loops it for easy use

A brief taste of vue

Foreword:

        I found a lot of information on the Internet about custom form objects for loop processing. I was confused by what was written. In the end, I directly modified the component to improve it, and directly used v-for for loop binding to implement it. This example implements a custom menu bar and vue-router routing to point to the menu and perform routing jumps, which is mainly implemented by the el-menu component.

Custom objects must be configured with paths for routing jumps

This example project structure:

Idea:

 The main purpose is to implement the construction of the continer framework in app.vue, and to implement page jumps in the contatiner to locate the customized components. The total component I positioned at this location is menutree.vue, and put <router-view/> In this component, when the route needs to jump, the component is directly positioned and modified.

Key points:

Here is the link that mainly solves the menu bar jump

1. To implement route jump, first add the router attribute to the el-menu tag, and then just set the url in the index attribute in each el-menu-item tag to click el-menu-item to realize the route jump. change.
2. Navigate the current item and bind it in the el-menu tag: default-active="$route.path". Note that it is a binding attribute. Don't forget to add

Code:
vue+elementui project el-menu navigation bar implements routing jump and setting of current item_elementui menu routing_Blog between the North and South Pole-CSDN Blog
