Vue学习之路由vue-router传参及嵌套小结（十）

一、路由传递参数：

1、使用query传值：

<!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>路由</title>
    <script src="./lib/vue.js"></script>
    <!-- 1.安装vue-router路由模块 -->
    <script src="./lib/vue-router.js"></script>
  </head>
  <body>
    <div id="app">
      <!-- 如果在路由中，使用 查询字符串，给路由传递参数，则不需要修改路由规则的path属性 -->
      <router-link to="/login?id=10&name=zs">登录</router-link>
      <router-link to="/register">注册</router-link>
      <router-view></router-view>
    </div>
    <script>
      var login = {
        template:
          "<h1>登录--{{ $route.query.id }}--{{ $route.query.name }}</h1>",
        data() {
          return {
            msg: "123"
          };
        },
        creadtd() {
          //组件的生命周期钩子函数
          // console.log(this.$route);
          console.log(this.$route.query.id);
        }
      };
      var register = {
        template: "<h1>注册组件</h1>"
      };
      var routerObj = new VueRouter({
        routes: [
          { path: "/login", component: login },
          { path: "/register", component: register }
        ]
      });
      var vm = new Vue({
        el: "#app",
        data: {},
        methods: {},
        router: routerObj
      });
    </script>
  </body>
</html>

2、使用params 传参：

地址上需要设置下第二个参数ID

<!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>路由</title>
    <script src="./lib/vue.js"></script>
    <!-- 1.安装vue-router路由模块 -->
    <script src="./lib/vue-router.js"></script>
  </head>
  <body>
    <div id="app">
      <!-- 如果在路由中，使用 查询字符串，给路由传递参数，则不需要修改路由规则的path属性 -->
      <router-link to="/login/12">登录</router-link>
      <router-link to="/register">注册</router-link>
      <router-view></router-view>
    </div>
    <script>
      var login = {
        template: "<h1>登录--{{ $route.params.id }}</h1>",
        data() {
          return {
            msg: "123"
          };
        },
        creadtd() {
          //组件的生命周期钩子函数
          console.log(this.$route.params.id);
        }
      };
      var register = {
        template: "<h1>注册组件</h1>"
      };
      var routerObj = new VueRouter({
        routes: [
          // 除了上面的字母的不同外，这里还需要设置下添加的第二个参数id
          { path: "/login/:id", component: login },
          { path: "/register", component: register }
        ]
      });
      var vm = new Vue({
        el: "#app",
        data: {},
        methods: {},
        router: routerObj
      });
    </script>
  </body>
</html>

二、嵌套路由children：

<!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>路由</title>
    <script src="./lib/vue.js"></script>
    <!-- 1.安装vue-router路由模块 -->
    <script src="./lib/vue-router.js"></script>
  </head>
  <body>
    <div id="app">
      <router-link to="/account">Account</router-link>
      <router-view></router-view>
    </div>
    <template id="tmp1">
      <div>
        <h1>这是Account组件</h1>
        <router-link to="/account/login">登录</router-link>
        <router-link to="/account/register">注册</router-link>
        <router-view></router-view>
      </div>
    </template>
    <script>
      var account = {
        template: "#tmp1"
      };
      var login = {
        template: "<h3>登录组件</h3>"
      };
      var register = {
        template: "<h3>注册组件</h3>"
      };
      var router = new VueRouter({
        routes: [
          {
            path: "/account",
            component: account,
            // 使用children 属性，实现子路由，同时子路由的path前面，不要带/，
            // 否则永远以根路径开始请求，这样不方便我们用户去理解URL地址
            children: [
              {
                path: "login",
                component: login
              },
              {
                path: "register",
                component: register
              }
            ]
          }
        ]
      });
      var vm = new Vue({
        el: "#app",
        data: {},
        methods: {},
        router
      });
    </script>
  </body>
</html>
