Vue前端路由

用前提醒:
	在导入Vue路由钱,要先导入Vue,不然会报错
		<script src="./lib/vue_2.5.22.js"></script>
		<script src="./lib/vue-router_3.0.2.js"></script>

	1.
		路由规则中,component只接收路由组件,不接收直接的字符串'<h1></h1>'
	2.
		最后要把路由实例对象挂载到Vue实例对象汇总
	3.命名路由
		<router-link :to="{ name: 'xm1'}">User3</router-link>  to前面有: !!!!!!!!!!!
	4.这样子App组件和重定向的User组件都会被渲染出来,因为User是App的子组件
		{path:'/',component:App,redirect: '/user',children:[
				{path:'/user',component:User},}
				
知识:
	1.基本使用:
		1.引入相关的库文件
		2.添加路由链接
		3.添加路由填充位
		4.定义路由组件
		5.配置路由规则并创建路由实例
		6.把路由挂载到 Vue 根实例中

    2.路由重定向:{path:'/', redirect: '/user'},
    3.嵌套路由用法
    4.动态匹配路由的基本用法
        1.动态路径参数 以冒号开头
            <router-link to='/register/tab/1'>Tab1</router-link>
            {path:'/register/tab/:id',component:Tab,props:true},
            Tab组件中
                props:['id'],
                template:'<h1>Tab  {{id}}</h1>'
                
                
            或者:
            <router-link to='/register/tab/1'>Tab1</router-link>
            {path:'/register/tab/:id',component:Tab,props:{id:3,name:'小明'}},
            props:['id','name'],
       2.路由组件中通过$route.params获取路由参数
        {path:'/register/tab/:id',component:Tab,props:route=>({name:'小明',id:route.params.id})},
    例子:
        <!DOCTYPE html>
        <html lang="en">
          <head>
            <meta charset="UTF-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1.0" />
            <meta http-equiv="X-UA-Compatible" content="ie=edge" />
            <title>Document</title>
            <!-- 导入 vue 文件 -->
            <script src="./lib/vue_2.5.22.js"></script>
            <script src="./lib/vue-router_3.0.2.js"></script>
          </head>
          <body>
            <div id='app'>
                <router-link to="/user">User</router-link>

            <script type="text/javascript">

                  },

                }
                const Register = {
                    template:`
                <div>
                  <h1>Register</h1>
                  <button @click='fn'>返回</button>
                </div>`,
                methods:{
                  fn:function () {

                    this.$router.go(-1)
                  }
                }
              }


                var router = new VueRouter({
                     routes:[
                        {path:'/' ,redirect:'/user'},
                        {path:'/user',name:'xm1',component:User},
                        {path:'/register',name:'xm2',component:Register}
                     ]
                })

                const vm = new Vue({
                    el: '#app',
                    data:{
                    },
                    router:router
                })
            </script>
          </body>
        </html>
