day88-4VueRouter之安装使用  https://www.bilibili.com/video/av35435753/?p=35

1. 现在的架构:前后端分离

 今日内容:

 

2. VueRouter组件下载及安装

 

 

 2.1 做一个例子,分为使用VueRouter、vue组件和不使用任何组件两种情况;

2.1.1 无组件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <!--<script href="./statics/vue.min.js"></script>-->
    <!--<script src="https://cdn.staticfile.org/vue/2.2.2/vue.min.js"></script>-->
</head>
<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':
                    oDive.innerHTML = `<h1>这是注册页面</h1>`;
                    break;
                default:
                    oDiv.innerText = `<h1>这是首页</h1>`;
                    break;
            }
        }
    </script>
</body>
</html>

先使用浏览器运行该代码,然后在地址栏添加 #/login 即可

 2.1.2 使用Vue&VueRouter组件

<!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>
</head>
<body>
<div id="app"></div>
<script>
    Vue.use(VueRouter);  //1.在Vue根实例中使用,VueRouter

    let Home = {
        template: `
        <div>
            <h1>这是首页页面 </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>`
    };
    //4. 使用router-link,router-view
    let App = {
        /*template:`
         <div>
         <app-home></app-home>
         <app-login></app-login>
         <app-register></app-register>
         `,
         components:{
         'app-home':Home,
         'app-login':Login,
         'app-register':Register
         }*/
        //router-link会渲染成a标签,to变成href属性;router-view是渲染的出口
        template: `
            <div>
                <router-link to="/">首页</router-link>
                <router-link to="/register">注册</router-link>
                <router-link to="login">登录</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进行绑定
    let router = new VueRouter({
        routes: [
            {
                path: '/',
                component: Home
            },
            {
                path: '/login',
                component: Login
            },
            {
                path: '/register',
                component: Register
            }
        ]
    });
    new Vue({
        el: "#app",
        template: `<App/>`,
        //3. 第三步,在根实例中注册router对象
        router: router,
        components: {
            App
        }
    })
</script>
</body>
</html>
