小编给大家分享一下MUI如何实现上拉刷新/下拉加载功能,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
新闻信息列表必备的功能,支持Table,Ul等列表.
以下是DIV版本,在安卓端或者ios端必须使用双webview模式,传送门:http://dev.dcloud.net.cn/mui/pulldown/
<!--下拉刷新容器--> <div id="pullrefresh" class="mui-content mui-scroll-wrapper"> <div class="mui-scroll"> <!--数据列表--> <ul class="mui-table-view"> </ul> </div> </div> <script type="text/javascript"> mui.init ({ pullRefresh: { container: '#pullrefresh', down: { callback: pulldownRefresh }, up: { contentrefresh: '正在加载...', callback: pullupRefresh } } }); /* * 下拉刷新具体业务实现 */ function pulldownRefresh() { setTimeout(function() { var table = document.body.querySelector('.mui-table-view'); var cells = document.body.querySelectorAll('.mui-table-view-cell'); //模拟数据 for (var i = cells.length, len = i + 3; i < len; i++) { var li = document.createElement('li'); li.className = 'mui-table-view-cell'; li.innerHTML = '<a class="mui-navigate-right">Item ' + (i + 1) + '</a>'; //下拉刷新,新纪录插到最前面; table.insertBefore(li, table.firstChild); } mui('#pullrefresh').pullRefresh().endPulldownToRefresh(); //refresh completed }, 1500); } var count = 0; /* * 上拉加载具体业务实现 */ function pullupRefresh() { setTimeout(function() { mui('#pullrefresh').pullRefresh().endPullupToRefresh((++count > 2)); //参数为true代表没有更多数据了。 var table = document.body.querySelector('.mui-table-view'); var cells = document.body.querySelectorAll('.mui-table-view-cell'); for (var i = cells.length, len = i + 20; i < len; i++) { var li = document.createElement('li'); li.className = 'mui-table-view-cell'; li.innerHTML = '<a class="mui-navigate-right">Item ' + (i + 1) + '</a>'; table.appendChild(li); } }, 1500); } if (mui.os.plus) { mui.plusReady(function() { setTimeout(function() { mui('#pullrefresh').pullRefresh().pullupLoading(); }, 1000); }); } else { mui.ready(function() { mui('#pullrefresh').pullRefresh().pullupLoading(); }); } </script>
个人心得
1、手动加载loading,并且会立即调用[下拉刷新]绑定的函数
mui('#pullrefresh').pullRefresh().pullupLoading(); //使用这个之后,自动会加载[下拉刷新]绑定的函数
2、停止上拉刷新和下拉加载的loading
mui('#pullrefresh').pullRefresh().endPullupToRefresh(num >= cnt); //参数可以为返回true/false的表达式 mui('#pullrefresh').pullRefresh().endPulldownToRefresh();
3、初始化
初始化时通常要将原数据列表清空,如:$("#mui-table-view").html("");
那么请务必将以下代码放置在清空代码之后.这和scroll的滚动性质有关
mui('#pullrefresh').pullRefresh().refresh(true); //恢复滚动 mui('#pullrefresh').pullRefresh().scrollTo(0,0,100); //滚动置顶
4、Iscroll方面的扩展和内容

5 Vue使用
<template> <div> <header class="mui-bar mui-bar-nav"> <button @click="model" class=" mui-btn mui-btn-blue mui-btn-link mui-btn-nav mui-pull-left"><span class="mui-icon mui-icon-left-nav"></span>{{ modelName }}</button> <h2 class="mui-title">笑话大全</h2> </header> <div class="mui-content mui-scroll-wrapper" id="pullrefresh" > <div class="mui-scroll"> <div class="mui-card" v-for="item in items"> <div class="mui-card-header mui-card-media" > <div class="mui-card-content-inner"> <p >{{ item.content }}</p> </div> </div> <div class="mui-card-content" v-if="item.url"> <img :src=" item.url " width="100%" height="100%" draggable="false"/> </div> <div class="mui-card-footer"> Posted on {{ item.updatetime }} </div> </div> </div> </div> </div> </template> <script> export default { data () { return { items:[], page :1, pagesize:5, count:0, modelName:"图文" }; }, methods : { getJoke () { let self = this; var model = self.modelName == "图文" ? "pic" : ""; $.ajax({ type:"get", url:`http://localhost:8090?${model}&page=${self.page}&pagesize=${self.pagesize}`, success (data) { let json = JSON.parse(data).result.data; self.items = self.items.concat(json); // 合并并且返回一个新数组 self.page += 1; self.count += 10; mui('#pullrefresh').pullRefresh().endPullupToRefresh(self.count >= 1000); } }) }, model () { this.modelName = this.modelName == "图文" ? "文字" : "图文"; this.items = []; this.getJoke(); }, pulldownRefresh () { setTimeout(() => { mui('#pullrefresh').pullRefresh().endPulldownToRefresh(); },1500) }, pullupRefresh () { this.getJoke(); } }, created () { let self = this; mui.ready(function(){ mui.init ({ pullRefresh: { container: '#pullrefresh', down: { callback: self.pulldownRefresh }, up: { contentrefresh: '正在加载...', callback: self.pullupRefresh } } }); self.getJoke(); }) } }; </script> <style lang="css" scoped> .mui-card:nth-last-child(1){margin-bottom:70px;} .mui-card-header>img:first-child{width:100%;height: 100%;} .mui-pull-bottom-pocket{position:inherit} </style>
