How to click to jump to the homepage in uniapp

With the development of mobile Internet, mobile APP has become an indispensable tool in our daily life. For developers, how to jump between APP pages is also a crucial part. This article will introduce how to implement the function of clicking to jump to the homepage in uniapp.

uniapp is a development tool based on the Vue.js framework. The applications developed by it can run on various mobile platforms at the same time, such as iOS, Android, etc. The page jump of uniapp is implemented based on Vue Router, so we need to understand how to use Vue Router.

First, we need to install the Vue Router plug-in in the uniapp project. Open the terminal, switch to the root directory of the project folder, and execute the following command:

npm install --save vue-router

After the installation is completed, we need to create a new router folder in the src directory and create an index.js file in it. In the index.js file, we need to introduce Vue and Vue Router:

import Vue from 'vue'
import Router from 'vue-router'

and then define the pages that need to be jumped. Here we can set the routing path and corresponding components of each page in advance. For example, we assume that the routing path of the homepage is "/main" and the corresponding component is MainPage:

import MainPage from '@/pages/main'

Next, create a Vue Router instance:

const router = new Router({
  routes: [
    {
      path: '/main',
      name: 'MainPage',
      component: MainPage
    }
  ]
})

In this instance, we define A route named "MainPage", its corresponding component is the MainPage component we defined. In actual projects, we need to set it according to the actual situation of each page.

In order for the Vue instance to use this Vue Router instance, we need to register it in the main Vue instance. Open the src/main.js file and add the following code:

import router from '@/router'

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

Here, we inject the router instance into the main Vue instance, so that we can directly call the router in the page to implement the jump function.

Suppose we need to implement the function of jumping to the homepage in the click event of a certain page. We can add the following code to the Vue component of this page:

methods: {
  goMainPage() {
    this.$router.push({ path: '/main' })
  }
}

In this goMainPage method , we use the $router.push method to implement route jump. Among them, { path: '/main' } means that the path of the page we want to jump to is "/main". This path needs to be consistent with the path we defined in the Vue Router instance.

Finally, trigger the goMainPage method on the page to realize the function of jumping to the homepage. For example, we add the following code to the click event of a button:

<button @click="goMainPage">跳转到主页</button>

The above is the detailed method to implement the function of clicking to jump to the homepage in uniapp. Through the Vue Router instance, we can easily jump between various pages to facilitate our APP development.
