How vue sets routing based on background routing parameters

Vue.js is an open source JavaScript framework that provides a complete front-end development framework, mainly used for building user interfaces. The Vue.js framework can flexibly adapt to various needs, such as building single-page applications (SPA), PC websites, mobile applications, etc. Vue.js can set routes according to the background routing parameters, making page jumps more convenient. This article will introduce in detail how to implement this function.

1. Preconditions

Before starting to use Vue.js to set routing based on background routing parameters, we need to understand several preconditions:

1. Be familiar with the basic knowledge of the Vue.js framework and routing components;
2. Be familiar with front-end and back-end interactions, especially the parameter passing methods of front-end routing and background routing;
3. Master Vue .js API related to routing components.

If you have met the above prerequisites, then we can start using Vue.js to set routing based on background routing parameters.

2. Set routing based on background routing parameters

1. In Vue.js, we can use the route.params attribute to obtain routing parameters. This property is useful for getting the parameters of the current route.
2. As shown in the following example, we can use the props attribute to bind the route.params object in the routing component to access the routing parameters.

const router = new VueRouter({
    routes: [
        {
            path: '/user/:id',
            component: User,
            props: true
        }
    ]
})

const User = {
    props: ['id'], // 绑定路由参数
    template: '<div>User {{ id }}</div>'
}

3. In the above example, we used the dynamic routing parameter: id, and bound the id as a routing parameter in the props attribute of the User component, so that it can be used in the User component Routing parameters are accessed through props.id.
4. In actual development, we may need to configure routing jumps based on background routing parameters, which can be achieved by writing corresponding methods.

const router = new VueRouter({
    routes: [
        {
            path: '/user/:id',
            component: User,
            props: true
        }
    ]
})

function goUserPage(id) {
    router.push({
        name: 'user',
        params: { id: id }
    })
}

5. In the above code, we defined a method named goUserPage, which is used to jump to the user details page based on the id passed in from the background, which is done through the push method of the router. Route jump, the name parameter indicates the name of the route to be jumped, and the params parameter indicates the route parameters to be passed.
6. Finally, when calling the goUserPage method, you can pass in the routing parameter id passed in the background as a parameter to jump to the corresponding page.

3. Summary

Through the above steps, we can implement routing jumps based on background routing parameters in the Vue.js framework. In actual development, this function allows us to handle routing jump logic more flexibly and improve the interactivity and user experience of the page. At the same time, attention should also be paid to the unification and standardization of routing parameter transmission methods at the front and back ends to ensure the stability and maintainability of the system.
