Why making this plugin

  • There are so many vue plugins on github,but i haven't found a suitable mini vue plugin for scroller.The best scroller plugin i have seen is the 'better-scroller',however it's not for vue especially.I decide to make a mini vue scroller plugin for my own company programs also for people who wanna use scroller simply.

What you can do with the plugin

  • You can use it to make a scroller container includes pulling-refresh,infinite-loading and horizonal scroller also supporting nesting different direction scroller.

horizonalMode verticalMode

How to use

  • NPM install the v-scroller plugin
yarn add v-scroller   or   npm install v-scroller --save

1.vue spa

  • import the plugin and use
import scroller from 'v-scroller'
import 'v-scroller/dist/v-scroller.css'
Vue.use(scroller)

2.script html

  • directly write the script,in deed you have to insert the vue.js script firstly
<link rel="stylesheet" href="node_modules/v-scroller/dist/v-scroller.css"></link >
<script src="node_modules/v-scroller/dist/v-scroller.js"></script>
  • use the component scroller directly in your vue spa file or the Vue instance
<scroller />

		<div slot="nomore" class="nomore">there is nomore data~</div>
	</scroller>
	<!--goTop using the scrollTo() function-->
	<div class="record" @click="goTop">
		x:{{left}},y:{{top}}
	</div>
</template>
<script>
export default{
	data(){
		return{
			num:[],
			snapping:true,
			isDownFresh:true,
			isUpLoad:true,
			smooth:true,
			horizonalMode:true,
			left:0,
			top:0
		}
	},
	created(){
		for(let i=0;i<5;i++){
			this.num.push(i)
		}
	},
	methods:{
		downfresh(done){
			console.log('refreshing finished')
			let b = this.num[0];
			for(let i = b;i>=b-5;i--){
				this.num.unshift(i);
			}
			done() // you should call the done to close the loading
		},
		upload(done){
			console.log('infinite loading finished')
			if(this.num[this.num.length-1]<25){
				let b = this.num[this.num.length-1];
				for(let i = b+1;i<=b+5;i++){
					this.num.push(i);
				}
				done() // you should call the done to close the loading
			}else{
				this.$refs.scroll.closeLoad();
			}
		},
		showPosition(){
			let {x:left,y:top} = this.$refs.scroll.getPosition();
			this.left = left;
			this.top = top;
		},
		goTop(){
			this.$refs.scroll.scrollTo(0,true);
			this.showPosition();
		}
	}
}
</script>

It's suggested that write a single function for ajax in methods and then use the ajax function at the lifeCircle of created，you can continue to use it at the plugin emiting event -- upLoad.Like this：

	created(){
		//when the component created ,use the ajax function firstly
		this.refreshData();
	},
	methods:{
		refreshData(done){
			const data = `telephone=${this.$store.state.BookOrderInfo.telephone}&start=${this.start}&limit=${this.limit}`
			this.$http({
				method:'POST',
				url:this.$_URL+'/api/listHistoryRecord',
				data:data
			})
			.then(
				res=>{
					if(res.data.code == '0000'){
						//if nomore data from the back-end ,use the plugin function closeLoad()
						if(res.data.data.length==this.History.length){
							this.$refs.scroller.closeLoad();
						}else{
							this.History = res.data.data;
							done()
						}
					}
			})
			.catch(
				err=>console.log(err)
			)
		},
		upLoad(done){
			this.limit+=this.limit;//this is the length of data while you request the back-end
			this.refreshData(done);
		}
	}

  • beforeScroll before you scroll just mean you touch the container.
  • scroll when you're scrolling the container.
  • afterScroll after you scroll just mean you raise your finger from the container.
