This time I will show you how mint-ui realizes the infinite scrolling loading function. What are the precautions for mint-ui to realize the infinite scrolling loading function. The following is a practical case. Let’s take a look. one time.

After climbing the pit many times, I discovered the commonality of these monitoring scrolling to load more components,

Because these methods of loading more are bound to elements that need to load more content,

So when you enter the page, it will be triggered directly once. When the scroll event is heard, continue to load more,

Therefore, for infinite scroll loading, there is no need to write the function for the first load list,

code show as below:

html:

//父组件
<p v-infinite-scroll="loadMore" infinite-scroll-disabled="loading" infinite-scroll-distance="1000">
   <LifeLists :loadingTextBtn="loadingTextBtn" :loadingText="loadingText" :loadingComplete="loadingComplete" :lifeList="lifeList"></LifeLists>
</p>
//LifeLists组件：
<LifeListItem :lists="lifeList"></LifeListItem>
  <p class="loading-text" v-show="{loadingTextBtn:true}">
   <span v-text="loadingText"></span>
   <mt-spinner v-if="(loadingComplete==false)" type="snake" :size="16"></mt-spinner>
</p>
LifeListItem组件：
<p id="lifeListItemBox">
<router-link v-for="(item,index) in lists" :to="{name:&#39;lifeDetails&#39;,params:{id:item.id}}" :key="index">
   <p class="lifeListItem1" v-if="(item.status==&#39;online&#39;)">
   <p v-if="(item.hasPrice==true)">
    <p class="title1">{{item.title}}</p>
    <p class="price">
    <b class="now"><span class="unit">{{item.monetaryUnit}}</span>{{item.price}}</b>
    </p>
   </p>
   <p v-else class="title2">{{item.title}}</p>
   <p class="info">
    发布于{{formatTime(item.createAt)}}
        
    {{item.countryName}} {{item.cityName}}
   </p>
   <p class="imageList">
    <img :src="img" alt="" v-for="(img,index) in item.photos">
   </p>
   <p class="content">{{item.detail}}</p>
   <p class="listBar">
    <p class="iconBox">
    <svg class="icon icon-dianzan" aria-hidden="true">
     <use xlink:href="#icon-dianzan" rel="external nofollow" ></use>
    </svg>
    {{item.like}}
    </p>
    <p class="iconBox">
    <svg class="icon icon-pinglun2" aria-hidden="true">
     <use xlink:href="#icon-pinglun2" rel="external nofollow" ></use>
    </svg>
    {{item.commentCount}}
    </p>
   </p>
   </p>
  </router-link>
</p>

vue.js

data:

page:0,
  size:10,
  loadingTextBtn:false,
  loadingText:"努力加载中",
  loadingComplete:false,
  refreshComplete:false,
  city:"",
  country:""

Copy after login

methods:

loadMore() {
  this.loading = true;
  this.loadingTextBtn=true;
  if(parseInt(this.page)==0){
   this.$store.dispatch('loadMoreLifeList',{city:"纽约",country:"美国",category:"",page:this.page,size:this.size});
   this.page++;
  }else if(parseInt(this.page)>0&&parseInt(this.page)<parseInt(this.totalPages)){
   setTimeout(() => {
 //   this.$store.dispatch('loadMoreLifeList',{city:this.city,country:this.country,category:"",page:this.page,size:this.size})
    this.$store.dispatch('loadMoreLifeList',{city:"纽约",country:"美国",category:"",page:this.page,size:this.size});
    this.page++;
   }, 1000);
  }else{
   this.loadingText="已全部加载完成";
   this.loadingComplete=true;
   this.loading = false;
  }
  },

Copy after login

The important thing here is to judge that when the current page is 0, that is, the first page, there is no need to setTimeoutTimer and directly request loading. When more is loaded, a timer can be added.

I found a lot of mint-ui loadmore components on the Internet to implement pull-up to load more. Since the pull-up triggers the corresponding load more event, the data should not be automatically loaded when entering the page, so you can add one here to get the first Page data function.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
