How does vue not change the url

Vue.js is one of the most popular JavaScript frameworks currently. It helps developers quickly build complex single-page applications (SPA). In Vue.js, switching components usually causes the URL address to change. However, in some cases it is necessary to prevent URL address changes, and this article will explore some practical methods.

Use Vue Router's replace method instead of push method

Vue Router is the routing manager officially provided by Vue.js. It handles navigation and routing within the application. By default, Vue Router uses the push method to change URL addresses while navigating. For example:

this.$router.push('/new-page')

If you need to navigate to another page without changing the URL address, you can use the replace method. For example:

this.$router.replace('/new-page')

Using the history API

HTML5 provides the window.history object, which can change the URL address without refreshing the page. In Vue.js, we can use the history API to implement page navigation without changing the URL address.

First, we need to use the history.pushState method to add new state to the browser history object. For example:

history.pushState({}, '', '/new-page')

This will cause the URL address in the browser address bar to change to /new-page, but will not reload the page. Next, we need to update the components in the Vue.js application so that the content of the new page is displayed. We can use Vue Router's watch attribute to listen for changes in URL addresses to update components in the application. For example:

// 在Vue Router的路由配置中
const routes = [
  {
    path: '/new-page',
    component: NewPageComponent
  }
]

// 在Vue.js组件中
export default {
  watch: {
    $route(to, from) {
      // 在这里更新组件内容
    }
  }
}

Finally, to ensure that the user can navigate backward and forward in the browser history, we need to replace the current state of the application with the new state using the history.replaceState method. For example:

history.replaceState({}, '', '/new-page')

Use Hash address

In Vue.js, if you use Hash address, you can avoid changing the URL address. Hash address refers to the part of the URL address starting with the # character. When using hash addresses, the browser does not reload the page but navigates within the client. For example:

this.$router.push('/#new-page')

In Vue.js, we can use the mode attribute of Vue Router to configure the routing mode. For example:

const router = new VueRouter({
  mode: 'hash',
  routes: [
    {
      path: '/',
      component: HomeComponent
    },
    {
      path: '/new-page',
      component: NewPageComponent
    }
  ]
})

By setting mode to hash, we can make Vue Router use Hash addresses instead of full URL addresses when navigating.

Summary:

In Vue.js, preventing URL address changes can be achieved by using Vue Router's replace method, history API and Hash address. If we need to change the URL address, we can use the push method or modify the window.location object. Choose different solutions to implement according to specific needs.
