【好好学习】mh_h5

老规矩先放下有趣的项目的github地址：
https://github.com/yw738/mh_h5
然后我们放下动图

接下来我们一起分析代码吧
看包的话，UI部分是有用到有赞的UI
首先我们看main.js

import Vue from 'vue'

import router from './router'
import store from './store'
import axios from 'axios'
//获取带参数的值
import qs from 'qs'
import App from './App.vue'
import Vant from 'vant';
import 'vant/lib/index.css';
import "@/components/Js/index"
Vue.use(Vant);
Vue.config.productionTip = false
Vue.prototype.$axios = axios;
Vue.prototype.$qs = qs;

new Vue({
    router,
    store,
    render: h => h(App)
}).$mount('#app')

接下来看route.js中，我们大概会有哪些入口页面
里面有用到路由懒加载

import Vue from 'vue'
import Router from 'vue-router'
import List from './views/List.vue'
import Search from './views/Search.vue'
Vue.use(Router)

export default new Router({
    mode: 'hash',
    base: process.env.BASE_URL,
    routes: [{
            path: '/',
            name: 'home',
            component: () =>
                import ('./views/Home.vue')
        }, {
            path: '/list',
            name: 'list',
            component: List
        },
        {
            path: '/search',
            name: 'search',
            component: Search
        },
        {
            path: '/about',
            name: 'about',
            component: () =>
                import ('./views/About/About.vue'),//按需加载
            // meta: {
            //     isUseCache: true, // 是否需要缓存
            //     keepAlive: true // 缓存
            // }
        },
        {
            path: '/detail',
            name: 'detail',
            component: () =>
                import ('./views/Detail.vue')
        }
    ]
})

接下来我们来看App.vue
在入口route-view中加了判断是不是移动端，不是不显示内容，是就显示内容
同时还进行了缓存判断，进入到某些页面就会缓存起来

<template>
  <div id="app">
    <keep-alive include="AboutIndex" max="1" :exclude="isKeepalive?'':'AboutIndex'">
      <router-view v-if="isShow" />
    </keep-alive>
  </div>
</template>
<script>
import { Dialog } from "vant";
export default {
  data() {
    return {
      isShow: false,//验证用户是否是移动端预览
      isKeepalive: false,//是否对详情进行缓存
    };
  },
  methods: {
    init() {
      var sUserAgent = navigator.userAgent.toLowerCase();
      var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
      var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
      var bIsMidp = sUserAgent.match(/midp/i) == "midp";
      var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
      var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
      var bIsAndroid = sUserAgent.match(/android/i) == "android";
      var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
      var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
      if (
        bIsIpad ||
        bIsIphoneOs ||
        bIsMidp ||
        bIsUc7 ||
        bIsUc ||
        bIsAndroid ||
        bIsCE ||
        bIsWM
      ) {
        this.isShow = true;
        //这是移动端
      } else {
        //这是pc端
        this.isShow = false;
        Dialog.alert({
          title: "提示",
          message: "请使用移动设备来浏览该网页,以此得到更友好的体验!"
        }).then(() => {
          // on close
        });
      }
    }
  },
  created() {
    this.init();
  },
  watch: {
    //监听路由 判断是否进行keep-alive动态缓存 
    $route: function(to, from) {
      console.log('to>>>>>>>>>>>>>',to)
      console.log('from>>>>>>>>>>>',from)
      if (to.name === "detail"||to.name === "about") {
        this.isKeepalive = true;
      }else{
        this.isKeepalive = false;
      }
    }
  },
};
</script>

接下来我们开始看Home页面
有搜索还有轮播，以及封装了组件，传入大量图片

//HOME.vue
<template>
  <div class>
    <div class="flex tipBox">
      <van-search class="serchBox" disabled placeholder="请输入搜索关键词" @click="toSearch" shape="round" />
      <div>
        <img
          @click="setHouse"
          src="http://css.mangabz.com/v201911081548/mangabz/images/mobile/class.png"
          alt
        />
        <img
          @click="userHome"
          src="http://css.mangabz.com/v201911081548/mangabz/images/mobile/icon_user.png"
          alt
        />
      </div>
    </div>
    <div class="swiper">
      <van-swipe :autoplay="3000" :loop="true" indicator-color="white">
        <van-swipe-item v-for="(item,i) in imgList" :key="i">
          <router-link :to="item.link">
            <img :src="item.url" />
          </router-link>
        </van-swipe-item>
      </van-swipe>
    </div>

    <homeList :tit="topBox" :data="topBoxList" />
    <homeList :tit="bottomBox" :data="bottomList" />
    <!-- <div class="index_border" /> -->
    <!-- 申明 -->
    <div class="sm">

接下来看其引入的homeList组件

<template>
  <div class="home_box">

  margin-bottom: 0;

</style>

接下来看search页面

//search.vue
<template>
  <div class="top">
    <van-search v-model="value" placeholder="请输入搜索关键词" @search="onSearch" show-action shape="round">
      <div slot="action" @click="cancel">取消</div>

      // console.log("搜索的值:", val);
      console.log('this>>>>>>>>>>',this)
      if (val.trim() === "") {

        this.setSerchKey("");
        return;

        if (code === 0) {
          this.setSerchKey(val);
          this.$emit("serch", list);
        } else {
          Toast.fail("服务器挂了");
        }
      });
    },
    cancel() {
      this.$router.push({
        path: "/"
      });
    }
  },
  created() {
    let { serchKey, onSearch } = this;
    if (serchKey !== "") {
      this.value = serchKey;
      onSearch();
    }
  },
  computed: {
    ...mapState(["serchKey"])
  }
};
</script>

<style lang='less' scoped>
</style>

接下来看about页面

<template>
  <div class="about">
    <div class="back" @click="back">
      <img src="./../../assets/return-details.png" alt />
    </div>
    <div class="img_box">
