How to implement jump cancellation history in Vue Router

Vue is a popular JavaScript framework that is widely used in the development of web applications. Vue Router is the official router library for Vue, which is very useful when building single-page applications. Vue Router makes it easier for developers to manage application state and navigation. Vue Router also provides features such as dynamic routing and nested routing to help developers better manage the code base.

When using Vue Router, a very common requirement is to implement page jumps in scenarios such as e-commerce websites. In this case, after the user performs some operations, he jumps to another page. But this jump method may cause some trouble for users. For example, when the user returns to the previous page, the clicked products will be reloaded. This can lead to confusion and annoyance for users. Therefore, canceling jump history is a good solution.

So, how to implement jump cancellation history in Vue Router? Below, we'll provide some solutions.

Method 1: Use the replace method of Vue Router

Vue Router allows developers to use the replace method instead of the default push method to change routing. This method can be used to cancel history.

Here is an example:

router.replace('/path-to-url');

This method will replace the current route with the given path without creating a new entry in the browser history. This means that users cannot go back to the previous page, thus solving the problem of page reloading when returning.

Method 2: Use Vue Router's beforeRouteLeave and scrollBehavior methods

Vue Router provides two methods beforeRouteLeave and scrollBehavior. These methods can be used in combination to implement cancellation history.

The beforeRouteLeave method is a life cycle hook in Vue Router, which is triggered when the component leaves the route. Therefore, it can be used to override the default routing behavior. In the beforeRouteLeave method, you can use the scrollBehavior method to set whether the browser can go back in history mode through the scrollBehavior object. If the 'scrollBehavior' property is set in the object returned in the scrollBehavior method, the corresponding scrolling behavior will be performed when the browser's back button is clicked in history mode.

The following is an example:

beforeRouteLeave(to, from, next) {
  this.$router.replace(to.path)
  next(false);
},
scrollBehavior(to, from, savedPosition) {
  if (savedPosition) {
    return savedPosition
  } else {
    return { x: 0, y: 0 }
  }
}

In this example, we use the beforeRouteLeave method to override the default routing behavior, and use the this.$router.replace method to replace the default push method . This alternative does not add new entries to the history, thus preventing the page from reloading when the user backs off. The scrollBehavior method is used to set whether the browser can roll back.

Method 3: Use the history mode of Vue Router

Vue Router also provides a history mode, which can be used to cancel history records.

The following is an example:

const router = new VueRouter({
  mode: 'history',
  routes: [...]
})

In this example, we set the mode of Vue Router to history. This mode is based on the HTML5 history API, which stores routing information in the browser's history object instead of in the address bar's query string. This means that in history mode, users can enter and modify URLs directly in the address bar without worrying about problems in the history.

Summary

Vue Router is the router library officially provided by Vue, which provides some very useful functions. When it comes to implementing page jumps, canceling jump history is a very important requirement. In this article, we introduce three ways to cancel jump history. Using these methods, developers can better manage the state and navigation of applications and improve the user experience.
