本人正在基于 vue2.0 + webpack + es6 搭建前端架构，整理了部分插件，下面这个是下拉更新 上拉更多的，挺好用的，分享给大家。

把上面组件拷贝一下，存成后缀是.vue的组件放到你的component下， 然后引入到页面 , 下面是我引用的demo
上代码： 里面有注释哦，有问题给我留言！
{{item.name}}{{item.name}} import Scroll from ./y-scroll/scroll;export default{ data () { return { counter : 1, //默认已经显示出15条数据 count等于一是让从16条开始加载 num : 15, // 一次显示多少条 pageStart : 0, // 开始页数 pageEnd : 0, // 结束页数 listdata: [], // 下拉更新数据存放数组 downdata: [] // 上拉更多的数据存放数组 } }, mounted : function(){ this.getList(); }, methods: { getList(){ let vm = this;vm.$http.get(/repos/typecho-fans/plugins/contents/).then((response) => {vm.listdata = response.data.slice(0,15); }, (response) => {console.log(error); }); }, onRefresh(done) { this.getList(); done() // call done}, onInfinite(done) { let vm = this; vm.$http.get(/repos/typecho-fans/plugins/contents/).then((response) => { vm.counter++; vm.pageEnd = vm.num * vm.counter; vm.pageStart = vm.pageEnd - vm.num; let arr = response.data; let i = vm.pageStart; let end = vm.pageEnd; for(; i= response.data.length){ this.$el.querySelector(.load-more).style.display = one; return; } } done() // call done}, (response) => {console.log(error); });} }, components : {v-scroll: Scroll }}
