基于Vue的WebApp项目开发（六）

实现商品购买列表页面

步骤一：新建goodslist.vue文件

<template>
  <div id="tml">
    <!--利用mui中的图文表格组件实现-->
    <div id="mui-content" class="mui-content" style="background-color:#fff">
      <ul class="mui-table-view mui-grid-view">
        <li v-for="item in list" class="mui-table-view-cell mui-media mui-col-xs-6">
          <router-link v-bind="{to:'/goods/goodsinfo/'+item.id}">
            <img class="mui-media-object" :src="item.img_url" style="height: 250px;">
            <div class="mui-media-body" v-text="item.title"></div>
            <div class="desc">
              <p>
                <span>￥{{item.sell_price}}</span>
                <s>￥{{item.market_price}}</s>
              </p>
              <p>
                <h6 class="left">热卖中</h6>
                <h6 class="right">剩余{{item.stock_quantity}}件</h6>
              </p>
            </div>
          </router-link>
        </li>
      </ul>
    </div>
  </div>
</template>

<script>
  import { Toast } from 'mint-ui';
  // 代表vm
  export default {
    data() {
      return {
        list: []
      }
    },
    created() {
      this.getlist();
    },
    methods: {
      getlist() {
        //获取到商品列表数据
        var url = '../../../statics/json/goodslist.json';
        this.$http.get(url).then(function(res) {
          if(res.body.status != 0) {
            Toast(res.body.message);
            return;
          }
          //当服务器返回了正常数据的时候做赋值操作
          this.list = res.body.message;
        });
      }
    }
  }
</script>

<style scoped>
  #mui-content li {
    border: 1px solid rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 0 4px #000;
    -moz-box-shadow: 0 0 4px #000;
    box-shadow: 0 0 4px #000;
    margin-left: 4px;
    padding: 0px;
    background-color: #fff;
    margin-bottom: 6px;
  }  
  #mui-content .mui-media-body {
    color: #0094ff;
  } 
  #mui-content .desc {
    height: 60px;
    background-color: rgba(0, 0, 0, 0.2);
    margin-top: 10px;
    padding: 5px;
    text-align: left;
  } 
  #mui-content .desc span {
    color: #a22b2b;
    margin-right: 15px;
  }  
  #mui-content a {
    padding-left: 0px;
    margin-left: 0px;
  }  
  #mui-content .desc .right {
    position: absolute;
    right: 10px;
    bottom: 0px;
    font-weight: bold;
  }  
  #mui-content .desc .left {
    position: absolute;
    left: 10px;
    bottom: 0px;
    color: red;
    font-weight: bold;
  }
</style>

步骤二：新建goodslist.json文件

{
  "status": 0,
  "message": [
    {
      "id": 1,
      "title": "动漫被套床单",

      "stock_quantity": 200,
      "goods_no": "SD13313123"
    }, {
      "id": 2,
      "title": "二次元毛绒抱枕",

      "sell_price": 75,
      "market_price": 90,
      "stock_quantity": 800
    }
  ]
}

步骤三：在入口文件main.js中配置好路由规则

//导入vue核心包
import Vue from 'vue';

//导入App.vue的vue对象
import App from './App.vue';

//导入vue-router
import vueRouter from 'vue-router';

//将vueRouter对象绑定到Vue对象上
Vue.use(vueRouter);

//导入路由规则对应的组件对象
import home from './components/Home.vue';
import shopcar from './components/shopcar/car.vue';
import newslist from './components/news/newslist.vue';
import newsinfo from './components/news/newsinfo.vue';
import photolist from './components/photo/photolist.vue';
import photoinfo from './components/photo/photoinfo.vue';
import goodslist from './components/goods/goodslist.vue';

//定义路由规则
var router1 = new vueRouter({
    //改变路由激活时的class名称
  linkActiveClass: 'mui-active', 
  routes: [{
      path: '/',
      component: home 
    }, {
      path: '/home',
      component: home
    },
    {
      path: '/shopcar',
      component: shopcar
    },
    {
      path: '/news/newslist',
      component: newslist
    },
    {
      path: '/news/newsinfo/:id',
      component: newsinfo
    },
    {
      path: '/photo/photolist',
      component: photolist
    },
    {
      path: '/photo/photoinfo/:id',
      component: photoinfo
    },
    {
      path: '/goods/goodslist',
      component: goodslist
    }
  ]
});

//导入mint-ui的css文件
import 'mint-ui/lib/style.min.css';
//导入mint-ui组件对象
import mintui from 'mint-ui';
//在Vue中全局使用mintui
Vue.use(mintui);

//注册mui的css样式
import '../statics/mui/css/mui.css';

//导入一个当前系统的全局基本样式
import '../statics/css/site.css';

//将vue-resource在vue中绑定，自动在vue对象实例上注入一个$http对象就可以使用ajax方法了
import vueResource from 'vue-resource';
Vue.use(vueResource);

//定义一个全局过滤器实现日期的格式化
import moment from 'moment';
Vue.filter('datefmt', function(input, fmtstring) {
  //使用momentjs这个日期格式化类库实现日期的格式化功能
  //input代表左值（原始时间格式），fmtstring代表右值括号内的规则
  return moment(input).format(fmtstring);
});

//使用图片预览组件vue-preview
import VuePreview from 'vue-preview';
Vue.use(VuePreview);

//利用Vue对象进行解析渲染
new Vue({
  el: '#app',
  //使用路由对象实例
  router: router1,
  render: c => c(App) //es6写法
})

<template>
  <div id="tml">
    商品详情
  </div>
</template>

<script>
</script>

<style>

</style>

步骤二：修改goodslist.vue文件

            <img class="mui-media-object" :src="item.img_url" style="height: 250px;">
            <div class="mui-media-body" v-text="item.title"></div>
            <div class="desc">
              <p>
                <span>￥{{item.sell_price}}</span>
                <s>￥{{item.market_price}}</s>
              </p>
              <p>
                <h6 class="left">热卖中</h6>
                <h6 class="right">剩余{{item.stock_quantity}}件</h6>
              </p>
            </div>
          </router-link>
        </li>
      </ul>
    </div>
  </div>
</template>

<script>
  import { Toast } from 'mint-ui';
  // 代表vm
  export default {
    data() {
      return {
        list: []
      }
    },
    created() {

          }
          //当服务器返回了正常数据的时候做赋值操作
          this.list = res.body.message;
        });
      }
    }
  }
</script>

<style scoped>
  #mui-content li {
    border: 1px solid rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 0 4px #000;
    -moz-box-shadow: 0 0 4px #000;
    box-shadow: 0 0 4px #000;
    margin-left: 4px;
    padding: 0px;
    background-color: #fff;
    margin-bottom: 6px;

    position: absolute;
    left: 10px;
    bottom: 0px;
    color: red;
    font-weight: bold;
  }
</style>

步骤三：配置入口文件mian.js的路由规则

//导入vue核心包
import Vue from 'vue';

//导入App.vue的vue对象
import App from './App.vue';

//导入vue-router
import vueRouter from 'vue-router';

//将vueRouter对象绑定到Vue对象上
Vue.use(vueRouter);

//导入路由规则对应的组件对象
import home from './components/Home.vue';
import shopcar from './components/shopcar/car.vue';
import newslist from './components/news/newslist.vue';
import newsinfo from './components/news/newsinfo.vue';
import photolist from './components/photo/photolist.vue';
import photoinfo from './components/photo/photoinfo.vue';
import goodslist from './components/goods/goodslist.vue';
import goodsinfo from './components/goods/goodsinfo.vue';

//定义路由规则
var router1 = new vueRouter({
    //改变路由激活时的class名称
  linkActiveClass: 'mui-active', 
  routes: [{
      path: '/',
      component: home 
    }, {
      path: '/home',
      component: home
    },
    {
      path: '/shopcar',
      component: shopcar
    },
    {
      path: '/news/newslist',
      component: newslist
    },
    {
      path: '/news/newsinfo/:id',
      component: newsinfo
    },
    {
      path: '/photo/photolist',
      component: photolist
    },
    {
      path: '/photo/photoinfo/:id',
      component: photoinfo
    },
    {
      path: '/goods/goodslist',
      component: goodslist
    },
    {
      path: '/goods/goodsinfo/:id',
      component: goodsinfo
    }
  ]
});

//导入mint-ui的css文件
import 'mint-ui/lib/style.min.css';
//导入mint-ui组件对象
import mintui from 'mint-ui';
//在Vue中全局使用mintui
Vue.use(mintui);

//注册mui的css样式
import '../statics/mui/css/mui.css';

//导入一个当前系统的全局基本样式
import '../statics/css/site.css';

//将vue-resource在vue中绑定，自动在vue对象实例上注入一个$http对象就可以使用ajax方法了
import vueResource from 'vue-resource';
Vue.use(vueResource);

//定义一个全局过滤器实现日期的格式化
import moment from 'moment';
Vue.filter('datefmt', function(input, fmtstring) {
  //使用momentjs这个日期格式化类库实现日期的格式化功能
  //input代表左值（原始时间格式），fmtstring代表右值括号内的规则
  return moment(input).format(fmtstring);
});

//使用图片预览组件vue-preview
import VuePreview from 'vue-preview';
Vue.use(VuePreview);

//利用Vue对象进行解析渲染
new Vue({
  el: '#app',
  //使用路由对象实例
  router: router1,
  render: c => c(App) //es6写法
})

案例四（商品详情页轮播图实现）

步骤一：在subcom文件夹中封装一个公用轮播组件slider.vue

<template>
  <div id="tml">
    <mt-swipe :auto="2000">
      <mt-swipe-item v-for="item in imgs">
        <img :src="item.img">
      </mt-swipe-item>
    </mt-swipe>
  </div>
</template>

<script>
  export default {
    //用来接收父组件传入过来的数据
    props: ['imgs']
  }
</script>

<style scoped>
  /*重写轮播图样式*/
  
  .mint-swipe {
    height: 310px;
  }
  .mint-swipe-item {
    width: 100%;
    height: 300px;
  }
  .mint-swipe-item img {
    width: 100%;
    height: 80%;
  }
</style>

此时Home.vue的代码为

<template>
  <div id="tml">
      <!--使用组件结合mint-ui实现轮播图-->
    <silder :imgs="list"></silder>

    <!--使用MUI的九宫格-->
    <div class="mui-content">
      <ul class="mui-table-view mui-grid-view mui-grid-9">
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/news/newslist">
            <span class="mui-icon mui-icon-home"></span>
            <div class="mui-media-body">新闻资讯</div>
          </router-link>
        </li>
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/photo/photolist">
            <span class="mui-icon mui-icon-email"></span>
            <div class="mui-media-body">图片分享</div>
          </router-link>
        </li>
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/goods/goodslist">
            <span class="mui-icon mui-icon-chatbubble"></span>
            <div class="mui-media-body">商品购买</div>
          </router-link>
        </li>
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/feedback">
            <span class="mui-icon mui-icon-location"></span>
            <div class="mui-media-body">留言反馈</div>
          </router-link>
        </li>
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/vide">
            <span class="mui-icon mui-icon-search"></span>
            <div class="mui-media-body">视频专区</div>
          </router-link>
        </li>
        <li class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-3">
          <router-link to="/callme">
            <span class="mui-icon mui-icon-phone"></span>
            <div class="mui-media-body">联系我们</div>
          </router-link>
        </li>
      </ul>
    </div>

  </div>
</template>

<script>
  import { Toast } from 'mint-ui';
  import silder from './subcom/slider.vue';

  export default {
    components: {
      silder
    },
    data() {
      return {
        list: []
      }
    },
    created() {
      // 当页面中的data和methods对象都创建完毕以后，就会自动调用created
      this.getimgs();
    },
    methods: {
      getimgs() {
        // 实现轮播组件中的数据请求
        // 1.0 确定url
        var url = '../../statics/json/homeslide.json'
        console.log(url);
        // 2.0 调用$http.get()
        this.$http.get(url).then(function(response) {
          var data = response.body;
          //错误处理
          if(data.status != 0) {
            Toast(data.message);
            return;
          }
          // 如果服务器返回的数据正常则赋值给list
          this.list = data.message;
        });
      }
    }
  }
</script>

<style scoped>
  /*重写九宫格样式*/  
  .mui-content,
  .mui-content ul li a {
    background: #fff;
  }
  /*改变九宫格图标样式*/ 
  .mui-grid-9 .mui-icon-home:before,
  .mui-grid-9 .mui-icon-email:before,
  .mui-grid-9 .mui-icon-chatbubble:before,
  .mui-grid-9 .mui-icon-location:before,
  .mui-grid-9 .mui-icon-search:before,
  .mui-grid-9 .mui-icon-phone:before {
    content: '';
    display: inline-block;
    width: 50px;
    height: 50px;
    background-repeat: round;
  }
  .mui-grid-9 .mui-icon-home:before {
    background-image: url(../../statics/imgs/Hgrid/1.png);
  }
  .mui-grid-9 .mui-icon-email:before {
    background-image: url(../../statics/imgs/Hgrid/2.png);
  }
  .mui-grid-9 .mui-icon-chatbubble:before {
    background-image: url(../../statics/imgs/Hgrid/3.png);
  }
  .mui-grid-9 .mui-icon-location:before {
    background-image: url(../../statics/imgs/Hgrid/4.png);
  }
  .mui-grid-9 .mui-icon-search:before {
    background-image: url(../../statics/imgs/Hgrid/5.png);
  }
  .mui-grid-9 .mui-icon-phone:before {
    background-image: url(../../statics/imgs/Hgrid/6.png);
  }
</style>

步骤二：创建goodslunbo1.json和goodslunbo.json用来存放轮播图片

{
  "status": 0,
  "message": [
    {

步骤四：配置入口文件main.js的路由规则

//导入vue核心包
import Vue from 'vue';

//导入App.vue的vue对象
import App from './App.vue';

//导入vue-router
import vueRouter from 'vue-router';
//将vueRouter对象绑定到Vue对象上
Vue.use(vueRouter);

//使用图片预览组件vue-preview
import VuePreview from 'vue-preview';
Vue.use(VuePreview);

//导入mint-ui的css文件
import 'mint-ui/lib/style.min.css';
//导入mint-ui组件对象
import mintui from 'mint-ui';
//在Vue中全局使用mintui
Vue.use(mintui);

//注册mui的css样式
import '../statics/mui/css/mui.css';

//导入一个当前系统的全局基本样式
import '../statics/css/site.css';

//将vue-resource在vue中绑定，自动在vue对象实例上注入一个$http对象就可以使用ajax方法了
import vueResource from 'vue-resource';
Vue.use(vueResource);

//导入路由规则对应的组件对象
import home from './components/Home.vue';
import shopcar from './components/shopcar/car.vue';
import newslist from './components/news/newslist.vue';
import newsinfo from './components/news/newsinfo.vue';
import photolist from './components/photo/photolist.vue';
import photoinfo from './components/photo/photoinfo.vue';
import goodslist from './components/goods/goodslist.vue';
import goodsinfo from './components/goods/goodsinfo.vue';
import goodsdesc from './components/goods/goodsdesc.vue';

//定义路由规则
var router1 = new vueRouter({
    //改变路由激活时的class名称
  linkActiveClass: 'mui-active', 
  routes: [{
      path: '/',
      component: home 
    }, {
      path: '/home',
      component: home
    },
    {
      path: '/shopcar',
      component: shopcar
    },
    {
      path: '/news/newslist',
      component: newslist
    },
    {
      path: '/news/newsinfo/:id',
      component: newsinfo
    },
    {
      path: '/photo/photolist',
      component: photolist
    },
    {
      path: '/photo/photoinfo/:id',
      component: photoinfo
    },
    {
      path: '/goods/goodslist',
      component: goodslist
    },
    {
      path: '/goods/goodsinfo/:id',
      component: goodsinfo
    },
    {
      path: '/goods/goodsdesc/:id',
      component: goodsdesc
    }
  ]
});

//定义一个全局过滤器实现日期的格式化
import moment from 'moment';
Vue.filter('datefmt', function(input, fmtstring) {
  //使用momentjs这个日期格式化类库实现日期的格式化功能
  //input代表左值（原始时间格式），fmtstring代表右值括号内的规则
  return moment(input).format(fmtstring);
});

//利用Vue对象进行解析渲染
new Vue({
  el: '#app',
  //使用路由对象实例
  router: router1,
  render: c => c(App) //es6写法
})

实现购买功能区

步骤一：创建一个组件inputNumber.vue

<template>
  <div id="subtmpl">
    <div class="inleft div" @click="substrict">-</div>
    <div class="incenter div" v-text="count"></div>
    <div class="inright div" @click="add">+</div>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        count: 1 //代表购买商品的数量
      }
    },
    methods: {
      substrict() {
        this.count--;
        //                确保最小值为1
        if(this.count < 1) {
          this.count = 1;
        }
        this.sendmessage();
      },
      add() {
        this.count++;
        this.sendmessage();
      },
      sendmessage() {
        this.$emit('dataobj', this.count);
      }
    }
  }
</script>

<style scoped>
  #subtmpl .div {
    width: 40px;
    height: 25px;
    line-height: 25px;
    border: 1px solid #000;
    display: inline-block;
    text-align: center;
  }
</style>

步骤二：修改goodsinfo.vue文件

<template>
  <div id="tml">
    <!--1.0 商品轮播图-->
    <div class="silder">
      <silder :imgs="imgs"></silder>
    </div>

    <!--2.0 实现商品购买区-->
    <div id="buy">
      <h4 v-text="info.title"></h4>
      <p class="line"></p>

将底部的购物车图标中数字叠加

步骤一：涉及到三个页面的通信，因此需要创建一个共同的Vue对象。

vm.js

import Vue from 'Vue';

export const COUNTSTR = 'inputNumberCount';
export var vm = new Vue();

步骤二：修改根组件App.vue

<!--以后项目的根组件-->
<template>
  <div>
    <!--1.0利用mint-ui中的header组件实现整个系统的头部-->
    <mt-header fixed title="hello"></mt-header>

    <!--2.0利用vue-router的<router-view></router-view>进行占位-->
    <router-view></router-view>

    <!--3.0利用mui中的tabbar组件实现系统的底部-->
    <nav class="mui-bar mui-bar-tab">
      <router-link class="mui-tab-item" to="/home">
        <span class="mui-icon mui-icon-home"></span>
        <span class="mui-tab-label">首页</span>
      </router-link>
      <router-link class="mui-tab-item" to="#tabbar-with-chat">
        <span class="mui-icon mui-icon-email"></span>
        <span class="mui-tab-label">会员</span>
      </router-link>
      <router-link class="mui-tab-item" to="/shopcar">
        <span class="mui-icon mui-icon-contact"><span id="badge" class="mui-badge">0</span></span>
        <span class="mui-tab-label">购物车</span>
      </router-link>
      <router-link class="mui-tab-item" to="/tabbar-with-map">
        <span class="mui-icon mui-icon-gear"></span>
        <span class="mui-tab-label">搜索</span>
      </router-link>
    </nav>
  </div>
</template>

<script>
  import { vm, COUNTSTR } from './kits/vm.js';
  // 利用 vm.$on() 来注册 COUNT这个常量代表的事件
  vm.$on(COUNTSTR, function(count) {
    //1.0 将count值追加到购物车中
    var badgeobj = document.querySelector('#badge');
    badgeobj.innerText = parseInt(badgeobj.innerText) + count;
  });

  // 2.0负责导出.vue这个组件对象，它本质上是一个Vue对象
  // 所以Vue中该定义的元素都可以使用
  export default { // es6的导出对象的写法
    data() { //等价于 es5的 data:function(){
      return {

      }
    },
    methods: {

    },
    created() {

    }
  }
</script>

<style scoped>
  /* 3.0当前页面的CSS样式写到这里，其中scoped表示这个里面
      写的CSS代码知识在当前组件页面上有效，不会影响到其他组件页面
     * */
</style>

步骤三：修改goodsinfo.vue文件

<template>
  <div id="tml">
    <!--1.0 商品轮播图-->
    <div class="silder">
      <silder :imgs="imgs"></silder>
    </div>

    <!--2.0 实现商品购买区-->
    <div id="buy">
      <h4 v-text="info.title"></h4>
      <p class="line"></p>
      <ul>
        <li class="price">
          市场价: <s>￥{{info.market_price}}</s> 销售价：<span>￥{{info.sell_price}}</span>
        </li>
        <li>
          <li class="inputli">
            购买数量：
            <inputnumber v-on:dataobj="getcount" class="inputnumber"></inputnumber>
          </li>
        </li>
        <li>
          <mt-button type="primary" size="small">立即购买</mt-button>
          <mt-button type="danger" size="small" @click="toshopcar">加入购物车</mt-button>
        </li>
      </ul>
    </div>

    <div id="params">
      <h6>商品参数</h6>

项目结构：

本地存储购物数据

步骤一：创建一个负责操作localStorage的js文件

localSg.js

// 负责操作localStorage的文件
/*
 *  获取数据：var Str  =localStorage.getItem(key);
 *  添加和追加数据： localStorage.setItem(key,value) ,value 是一个字符串
 *  移除数据 ： localStorage.removeItem(key);
 * */

// 1.0 定义常量key,将来操作的localStorage中的数据都以这个key来作为标识
export const KEY = 'goodsdata';
export var valueObj = {
  goodsid: 0,
  count: 0
};

// 2.0 实现数据的增加
// value;格式： {goodsid:87,count:10}
export function setItem(value) {
  //1.0 获取json格式
  var jsonString = localStorage.getItem(KEY);
  jsonString = jsonString || '[]';
  var arr = JSON.parse(jsonString);
  // 2.0 将value追加进入arr
  arr.push(value);
  // 3.0 将arr 转换成json字符串保存起来
  localStorage.setItem(KEY, JSON.stringify(arr));
}

// 3.0 获取数据
export function getItem() {
  var jsonString = localStorage.getItem(KEY);
  //将json格式字符串转换成 js对象
  // jsonString：是一个标准的json格式
  jsonString = jsonString || '[]';

  return JSON.parse(jsonString);
}

// 4.0 移除数据
export function remoteItem() {

}

步骤二：修改goodsinfo.vue文件
