Implement refresh and tab switching in vue

Below I will share with you an example of vue refresh and tab switching, which has a good reference value and I hope it will be helpful to everyone.

First write a subcomponent to hold the refreshed content, named pull (you can see it at the end of the example.)

Then reference the page to be refreshed

<template>
   <p class="fbjbox container">
   <p class="fbjbox1">
  <tab ref=&#39;tab&#39; :list="[&#39;推荐&#39;,&#39;热门&#39;,&#39;最新&#39;]" width="33%" @change=&#39;tabchange&#39; style="float:left"/>
 <span class="price" width="33%" @tap="change" >价格<span class="mui-icon mui-icon-arrowright"></span></span> //点击价格会排序
   </p>
  <p class="fbjbox2">
   
   <pull up="true" down="true" @up="next" @down="shuaxin" ref="pull">
   
    <p class="mui-row mui-col-xs-12 mui-clearfix">
      <span class="mui-col-xs-6" v-href="{name:&#39;商品详情&#39;}" rel="external nofollow" v-for="item in list">
       <p class="img"><img v-bind:src="item.goods_image"/></p>
       <h4>{{item.goods_name}}</h4>
       <p class="red1">￥{{item.goods_price}}</p>
      </span>
     </p>
   
   </pull>
  
  </p>
</p>
</template>
<style>
 /*选项卡的颜色*/
 .tab{background:#fff;}
 .tab a.active{color:#D83737; border-bottom: 2px solid #D83737;} 
 .red1{color:red;font-size:15px;padding-left:10px}
 h4{font-size:16px;font-weight:normal;color:#656565;padding-left:10px}
</style>
<style scoped>
 .container{font-family: "微软雅黑";}
 .mui-row{ overflow: hidden;margin-bottom: 20px;}
 .mui-row .mui-col-xs-6{width:49%;background-color:#fff;overflow: hidden;margin-top:6px;text-align: left;}
 .mui-row .mui-col-xs-6:nth-child(even){margin-left:2%;}
 .mui-row img{width:100%;}
 .mui-row .img{height:170px;}
</style>
<script>
import tab from &#39;../tab&#39;
import pull from &#39;../public/pull&#39;
 export default {
   created() {
   this.height = window.innerWidth * 40 / 64;
   this.is_zc = this.$route.query.is_zc == 1;
   this.uid = localStorage.getItem(&#39;uid&#39;);
   
  
  },
  mounted(){
    this.shuaxin(() => { });
  
  },
  data() {
    return {
    tab:0,
    list:[],
   order:1 //order是排序。1的默认的，2从低到高，3从高到低
   }
  },
  components: {tab,pull},
  computed:{  //cmd也是一个变量 ，而且根据选项卡的不同而不同 
   cmd:function(){
    switch(this.tab){
     case 0: return "Mp/goodsTuijian";
     case 1: return "Mp/hotGoods";
     case 2: return "Mp/newGoods";
    }
    
   }
  },
  methods: {
   tabchange({index, data}) {
    this.tab = index;
    },
  shuaxin(done) { //首先进去以后的初始
    this.$api(this.cmd, { page: 0,order:this.sort }).then(list => { //除了把页面传过去还需要把排序的方式传过去
      this.list=list;
     done();
 //跳到一个新的选项卡时，页面从新从第一个.不是拉到的那个位置
   if(this.$refs.pull){
      this.$refs.pull.reset();
      this.$refs.pull.nodata = false;
      }
    });
   },
  next(done) {
    var page = this.list.length;
    this.$api(this.cmd, { page,order:this.sort }).then(list => {
     if (list.length == 0) { return done&&done(true);}  //这个里面如果只出现done(true)的话可能就是只显示没有数据了，不会出现正在加载中
     this.list = this.list.concat(list);
     done();
    });
   },
  change(){ //点击价格时变化的class
    if(this.sort==1){this.sort=2;}
    else
    if(this.sort==2){this.sort=3;}
    else
    if(this.sort==3){this.sort=1;}
    this.shuaxin(() => { });
   }
   
  },
  watch:{   //监听。当选项卡改变的时候，刷新页面。
   tab:function(){
    this.shuaxin(() => { });
    
   },
   
  }
 }
</script>

The following is the subcomponent named pull.

<template>
 <p class="mui-scroll-wrapper" ref="box" v-bind:style="{top:top+&#39;px&#39;}">

    };
   }
  },
  watch: {
   type(a, b) {
    if (b == 1) {
     this.type = 2;
    }
    if (a == 2) {
     this.flag = false;
     this.obj.setTranslate(0, 50);
     this.$emit("down", () => {
      this.type = 0;
      this.obj.setTranslate(0, 0);
      this.obj.reLayout();
      this.nodata = false;
     });
    }
   }
  },
  methods: {
  reset(){
    this.obj.setTranslate(0, 0);
   },
   scrollstart() {
    if (this.obj.lastY <= 0) {
     this.flag = true;
    } else {
     this.Y = 0;
     this.flag = false;
    }
   },
   scroll() {
    if (this.down && this.flag) {
     this.type = this.obj.y > 50 ? 1 : 0;
     if (this.obj.y > 0) {
      this.Y = this.obj.y;
     }
    }
   },
   scrollbottom() {

    this.type = 4;
    this.$emit("up", (n) => {
     this.type = 0;
     if (n == true) this.nodata = true;
     this.obj.reLayout();
    });
   }
  }
 }
</script>

An example of tab

<template>
 <p class="mypage">
 
   <p class="fbjbox">

    },
   changemes(){

     this.$api(this.cmd).then(list => { 
      this.count=list.count;
      this.list=list.list;
     
    });
   }
  },
  watch:{
   tab:function(){

   }
  }
 }
</script>
