Detailed analysis of the implementation of vue routing jump

With the continuous development of front-end technology, Vue.js, as a front-end framework, has been widely used in the development of various web applications. Among them, one of the most unique features of Vue.js is the routing mechanism it provides. Through the routing mechanism of Vue.js, we can easily jump between different pages to achieve the multi-page switching effect of web applications. So, what is the implementation process of Vue.js routing jump? The following will be analyzed in detail from the following aspects.

1. What is Vue.js routing

Before delving into the Vue.js routing jump implementation process, we need to first understand the basic concepts of Vue.js routing. Vue.js routing is a mechanism to control application state, which can map URL addresses to different Vue components, and switch different URL addresses and render different components through the browser's forward and back buttons. Vue.js routing is implemented through the vue-router plug-in officially provided by Vue.js.

2. How to jump Vue.js routes

There are many ways to jump Vue.js routes, including triggering through click events of tags, jumping programmatically, and jumping through Change the URL address to jump, etc. Different jump methods correspond to different application scenarios.

1. Triggered by the click event of the label

Triggered by the click event of the label is the most common Vue.js routing jump method. In Vue.js, the tag can be used to set the jump target address, jump method (such as normal jump, open in a new tab, etc.) and other attributes to achieve the jump effect between pages. . The specific usage of the tag is described in detail in the official documentation of the vue-router plug-in.

2. Jumping through programming

Jumping through programming is a relatively flexible route jumping method. Through the $router object provided by Vue.js, we can jump to a specified URL address and specify some parameters when jumping. For example, routing jump can be achieved through the following code:

this.$router.push({path: '/login', query: {name: 'user'}})

3. Jumping by changing the URL address

Jumping by changing the URL address is a common Pure front-end routing jump method. We can change the URL address through the history object or location object in JavaScript. During the process of changing the URL address, the routing jump mechanism of Vue.js will be triggered. For example, the routing jump can be implemented through the following code:

window.history.pushState({}, '', 'login?name=user')

3. The implementation process of Vue.js routing jump

The implementation process of Vue.js routing jump can be divided into the following Steps:

1. Resolve URL address

In the process of Vue.js routing jump, you first need to parse the URL address to determine the target page of the jump. The routing jump mechanism of Vue.js will parse the URL address and match different routing rules based on the identifiers (such as paths, query parameters, etc.) in the URL address.

2. Find matching routing rules

Once the various identifiers in the URL address are parsed, the Vue.js routing jump mechanism will perform routing matching for these identifiers. to determine the destination routing rules.

3. Route Navigation Guard

In the Vue.js route jump process, another very important mechanism is the route navigation guard. The route navigation guard is an interceptor that can perform some specific logical operations before or after the route jump, such as permission verification, page interception, etc. Route navigation guard is an important part of Vue.js route jump implementation.

4. Render the target page

According to the determined target routing rules, the Vue.js routing jump mechanism will render the corresponding Vue component into the page to complete the page jump. the process of.

Summary

Vue.js routing is a mechanism to control application status and is a common way to implement front-end page jumps. From the basic concepts of routing, different routing jump methods, and the process of implementing routing jumps, the Vue.js routing jump mechanism is very complete and flexible, and can meet the needs of a variety of different scenarios. At the same time, the implementation process of the Vue.js routing jump mechanism is relatively clear and easy to understand. During our Vue.js development process, we might as well study the Vue.js routing mechanism in depth to obtain better development efficiency and experience.
