VueRouter 实现原理

<body>
    <div id="app">
    </div>
    <script>
        let oDiv = document.getElementById("app");
        window.onhashchange = function () {
            switch (location.hash) {
                case ‘#/login‘:
                    oDiv.innerHTML = `<h1>这是登录页面</h1>`;
                    break;
                case ‘#/register‘:
                    oDiv.innerHTML = `<h1>这是注册页面</h1>`;
                    break;
                default:
                    oDiv.innerHTML = `<h1>这是首页</h1>`;
                    break;
            }
        }
    </script>
</body>
 
VueRouter  安装使用
<body>
    <div id="app">
    </div>
    <script>
        // 1. 在Vue根实例中使用,VueRouter
        Vue.use(VueRouter);
        let Home = {
            template: `
                <div>
                    <h1>这是主页页面</h1>
                </div>
            `
        };
        let Login = {
            template: `
                <div>
                    <h1>这是登录页面</h1>
                </div>
            `
        };
        let Register = {
            template: `
                <div>
                    <h1>这是注册页面</h1>
                </div>
            `
        };
        let App = {
            // 第四步
            // router-link会渲染成a标签,to会变成href属性,to后面是router中定义的路径
            // 第五步
            // router-view是页面内容的渲染出口
            template: `
                <div>
                    <router-link to="/">首页</router-link>
                    <router-link to="/login">登录</router-link>
                    <router-link to="/register">注册</router-link>
                    <router-view></router-view>
                </div>
            `,
        };
        // 2. 第二步实例化一个router对象
        // 本质上是将路径和页面内容绑定了对应关系
        let router = new VueRouter({
            routes: [
                {
                    path: ‘/‘,
                    component: Home,
                },
                {
                    path: ‘/login‘,
                    component: Login,
                },
                {
                    path: ‘/register‘,
                    component: Register,
                }
            ]
        });
        new Vue({
            el: "#app",
            template: `<App/>`,
            // 第三步,在根实例中注册router对象
            router: router,
            components: {
                App,
            }
        });
    </script>
</body>
 
VueRouter  路由命名
<body>
    <div id="app">
    </div>
    <script>
        // 1. 在Vue根实例中使用,VueRouter
        Vue.use(VueRouter);
        let Home = {
            template: `
                <div>
                    <h1>这是主页页面</h1>
                </div>
            `
        };
        let Login = {
            template: `
                <div>
                    <h1>这是登录页面</h1>
                </div>
            `
        };
        let Register = {
            template: `
                <div>
                    <h1>这是注册页面</h1>
                </div>
            `
        };
        let App = {
            // 第四步
            // router-link会渲染成a标签,to会变成href属性,to后面是router中定义的路径
            // 第五步
            // router-view是页面内容的渲染出口
            template: `
                <div>
                    <router-link :to="{ name: ‘home‘ }">首页</router-link>
                    <router-link :to="{ name: ‘login‘ }">登录</router-link>
                    <router-link :to="{ name: ‘register‘ }">注册</router-link>
                    <router-view></router-view>
                </div>
            `,
        };
        // 2. 第二步实例化一个router对象
        // 本质上是将路径和页面内容绑定了对应关系
        let router = new VueRouter({
            routes: [

一切分离都是为了更好的结合,本文详细介绍了前后端分离架构之后,前端如果实现路由控制,即Vue路由系统。

Vue路由系统

VueRouter实现原理

VueRouter的实现原理是根据监控锚点值的改变,从而不断修改组件内容来实现的,我们来试试不使用VueRouter,自己实现路由控制,如下代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="../statics/vue.min.js"></script>
<script src="../statics/vue-router.js"></script>
<style>
body {
margin: 0;
}
.login {
width: 100%;
height: 1200px;
background-color: #0FC57C;
}
.register {
width: 100%;
height: 1200px;
background-color: yellow;
}
.home {
width: 100%;
height: 1200px;
background-color: #2aabd2;
}
a {
text-decoration: none;
}
</style>
</head>
<body>

<div id="app">
<a href="#/home">首页</a>
<a href="#/login">登录</a>
<a href="#/register">注册</a>
</div>

<script>
let oDiv = document.getElementById("app");

window.onhashchange = function () {
console.log(location.hash);
// vue-router的实现原理是根据锚点值的改变
// 对页面进行切换
switch (location.hash) {
case "#/login":
oDiv.innerHTML = `<h3 class=‘login‘>这是登录页面</h3>`;
break;
case "#/register":
oDiv.innerHTML = `<h3 class=‘register‘>这是注册页面</h3>`;
break;
default:
oDiv.innerHTML = `<h3 class=‘home‘>这是首页</h3>`;
break;
}
};
</script>

</body>
</html>

可以看到,通过监控锚点值的改变,页面上面的内容可以跳转到我们需要显示的页面。
