How to use Vue to implement the special effect of returning to the previous page

In front-end development, we often encounter situations where we need to return to the previous page. By adding a back button, you can provide a better user experience. This article will introduce how to use the Vue framework to achieve the special effect of returning to the previous page, and provide corresponding code examples.

First, in the Vue project, you need to create a page as the previous page. We can set routes through Vue Router, and each route corresponds to a component. On the previous page, we can add a return button and achieve the return effect through click events.

Here is a simple sample code that shows how to create a previous page using Vue Router:

<template>
  <div>
    <h1 id="上一页">上一页</h1>
    <button @click="goBack">返回</button>
  </div>
</template>

<script>
export default {
  methods: {
    goBack() {
      this.$router.go(-1); // 返回上一页
    }
  }
}
</script>

In the above code, we create a previous page by using <button></button> element adds a back button and binds it to the goBack method. Inside the goBack method, we use this.$router.go(-1) to return to the previous page.

Next, we need to add a jump link to the current page to jump to the previous page.

The following is a sample code that shows how to use Vue Router to create a current page and add a jump link:

<template>
  <div>
    <h1 id="当前页">当前页</h1>
    <router-link to="/previous-page">跳转到上一页</router-link>
  </div>
</template>

<script>
export default {
}
</script>

In the above code, we use <router-link> component to create a jump link. Among them, the <code>to attribute specifies the path to jump, that is, the path of the previous page /previous-page.

In Vue Router, we need to configure routing information to jump to the previous page correctly.

The following is a sample code that shows how to configure Vue Router to jump to the previous page:

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const routes = [
  {
    path: '/previous-page',
    component: PreviousPage
  },
  {
    path: '/current-page',
    component: CurrentPage
  }
]

const router = new VueRouter({
  routes
})

export default router

In the above code, we set the routes array to configure routing information. Among them, the path attribute specifies the path, and the component attribute specifies the corresponding component.

In the Vue entry file, we need to introduce routing configuration and bind it to the Vue instance.

The following is a sample code that shows how to use Vue Router in Vue's entry file:

import Vue from 'vue'
import App from './App.vue'
import router from './router'

Vue.config.productionTip = false

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

In the above code, we import and add router to In the Vue instance.

Through the above example, we can use Vue to implement the special effect of returning to the previous page. Add corresponding components and routing information to the previous page and current page respectively, and use click events to achieve the return effect. In this way, users can be provided with a better navigation experience.
