How to implement replacement routing in Vue without switching tabs

With the continuous development of front-end technology, Vue has become a very popular front-end framework. In the Vue development process, the routing system is an indispensable and important part. However, sometimes we need to switch routes without refreshing the entire page, while also keeping the state of the current tab intact. This article will introduce how to implement replacement routing in Vue without switching tabs.

1. What is the Vue routing system?

In Vue, the routing system allows us to define routes for our application. Routing is the process of determining the content of a page based on the URL. The Vue routing system can dynamically load components and change the routing path of the URL as the user interacts with the page. This allows the application to be rendered "single page", i.e. without reloading the entire page.

2. Why do I need to replace the route without switching tabs?

When using routing in Vue, we usually use tabs to render page content. However, there are situations where we need to replace routing without switching tabs. For example, when the user clicks a button, you need to implement the content of another route to replace the content of the current route, however, the current tab should not switch.

3. How to implement replacement routing without switching tabs?

In Vue, we can use the routing hook function to intercept route navigation. Route hook functions allow us to execute custom code during route navigation. Using route hook functions, we can implement route replacement without switching tabs. The specific steps are as follows:

1) Define routing hook functions: In Vue, routing hook functions include "beforeRouteEnter", "beforeRouteLeave" and "beforeRouteUpdate". We can use these hook functions to intercept route navigation.

2) Use the "beforeRouteUpdate" hook function: This hook function is called when the current component is reused. We can get new routing parameters in this function and update the component state.

3) Use the "$router.replace" method: This method can replace the current route with a new route and will not add it to the history.

4) Bind routes in tabs: Finally, in Vue, we can use the "" tag to present route content. We can bind the route in the HTML code of the tab so that the content of the tab does not switch when using the "replace" method.

Here is an example showing how to use hook functions and the "$router.replace" method to implement replacement routing without switching tabs:

// 定义组件
const Home = {template: '<div>Home</div>'}
const About = {template: '<div>About</div>'}

// 定义路由
const routes = [
  {path: '/home', component: Home},
  {path: '/about', component: About}
]

// 创建Vue实例
const app = new Vue({
  router: new VueRouter({routes}), // 将路由配置添加到Vue实例中
  el: '#app',
  data () {
    return {
      currentTab: 'home' // 初始化选项卡
    }
  },
  methods: {
    replaceRoute (path) { // 替换路由方法
      this.$router.replace(path)
    }
  },
  watch: {
    '$route' (to, from) { // 监听路由变化
      if (to.path === '/about') { // 如果是“about”路由
        this.currentTab = 'about' // 更新选项卡状态
      } else {
        this.currentTab = 'home'
      }
    }
  }
})

<!-- 绑定路由到选项卡中 -->
<div id="app">
  <ul>
    <li :class="{active: currentTab === &#39;home&#39;}" @click="replaceRoute(&#39;/home&#39;)">Home</li>
    <li :class="{active: currentTab === &#39;about&#39;}" @click="replaceRoute(&#39;/about&#39;)">About</li>
  </ul>
  <router-view></router-view> <!-- 显示路由内容 -->
</div>

In this example, we first define The "Home" and "About" components then define routes, adding them to the routing configuration of the Vue instance. Next, we define a "replaceRoute" method for replacing routes. In the Vue instance, we use the "watch" option to listen for route changes and declare the status of the tab based on the route. Finally, in the HTML, we use the "" tag to render the route content and bind it into the tab.

4. Conclusion

In Vue, using the routing system can help us implement single-page applications. Sometimes, we need to replace routing without switching tabs. We can achieve this very easily by using routing hook function and "$router.replace" method. If you are new to Vue routing, this example should help you understand how Vue routing works.
