vue目前是众所周知的流行框架大家都知道的，vue全家桶的成员是：vue-cli,vuex,vue-router,vue-axios(vue2.0)。然后它的第三方插件也有很多，比如：vue-scroller,vue-lazyload,vue-awesome-swiper等等的。
之前我已经给大家介绍过vue-lazyload的用法了，今天就给大家说一下vue-scroller的用法吧。
首先在命令行进行npm||cnpm||bower下载
npm install vue-scroller -D
:::!!! -D:就是 --save -dev
然后在你想要用scrolle的那个页面里将咱们刚才下载的东西引入
import Vue from 'vue'
import VueScroller from 'vue-scroller'
Vue.use(VueScroller)
这个插件主要是标签<scroller>,谁需要进行上拉加载下拉刷新就给谁加。然后里面有:on-refresh="refresh"&&:on-infinite="infinite" || ref="domName"
:::!!! ref是获取dom元素的。
this.$refs.myscroller.resize()//重置大小=>myscroller是上面ref定义的dom元素的名字
this.$refs.myscroller.finishInfinite(2);//没有数据时的处理函数
然后在methods对象里加入两个函数：infinite()&&refresh()
infinite(done) {
if(this.noData) {
setTimeout(()=>{
this.$refs.myscroller.finishInfinite(2);
})
return;
}
let self = this;//this指向问题
let start = this.moveList.length;
setTimeout(() => {
for(let i = start + 1; i < start + 10; i++) {
self.moveList.push(i)
}
if(start > 30) {
self.noData = "没有更多数据"
}
self.$refs.myscroller.resize();
done()
}, 1500)
}
//done()表示这次异步加载数据完成，加载下一次
//因为这个是同步的，加了setTimeout就是异步加载数据；
//因为涉及到this指向问题，所以将他放在一个变量里。
refresh() {
console.log('refresh')
}

index.vue//因为我在这个组件里需要scroller
