How mint-ui implements infinite scrolling loading function

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>
   <lifelists></lifelists>
</p>
//LifeLists组件：
<lifelistitem></lifelistitem>
  <p>
   <span></span>
   <mt-spinner></mt-spinner>
</p>
LifeListItem组件：
<p>
<router-link>
   <p>
   </p>
<p>
    </p>
<p>{{item.title}}</p>
    <p>
    <b><span>{{item.monetaryUnit}}</span>{{item.price}}</b>
    </p>
   </router-link></p>
   <p>{{item.title}}</p>
   <p>
    发布于{{formatTime(item.createAt)}}
        
    {{item.countryName}} {{item.cityName}}
   </p>
   <p>
    <img  src="/static/imghwm/default1.png" data-src="img" class="lazy" alt="How mint-ui implements infinite scrolling loading function" >
   </p>
   <p>{{item.detail}}</p>
   <p>
    </p><p>
    <svg>
     <use></use>
    </svg>
    {{item.like}}
    </p>
    <p>
    <svg>
     <use></use>
    </svg>
    {{item.commentCount}}
    </p>
   
   
  

vue.js

data:

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

methods:

loadMore() {
  this.loading = true;
  this.loadingTextBtn=true;
  if(parseInt(this.page)==0){
   this.$store.dispatch('loadMoreLifeList',{city:"纽约",country:"美国",category:"",page:this.page,size:this.size});
   this.page++;
  }else if(parseInt(this.page)>0&&parseInt(this.page)<parseint> {
 //   this.$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;
  }
  },</parseint>

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.
