This article mainly shares with you the encapsulation process of mui pull-up loading to load more pull-down refresh data. Mui pull-up loading and pull-down refresh are similar and both belong to the pullRefresh plug-in. Friends in need can refer to it, I hope it can help everyone.
I used mui to make two projects. When I was free, I pulled up mui to load more, and pulled down to refresh the data to make a simple package. I hope it can help friends in need
demo project The structure
The code is directly pasted
index.html
mui pull-up refresh pull-down load is all here, two methods can be done

var pager = {};//分页

mui("#refreshContainer").pullRefresh({

contentover : "释放立即刷新",//可选，在释放可刷新状态时，下拉刷新控件上显示的标题内容

callback :function(){ //必选，刷新函数，根据具体业务来编写，比如通过ajax从服务器获取新数据；
window.setTimeout(function(){

pager['page'] = 1;//页码
//刷新要先清空父节点里面的子节点
var f = document.getElementById("list");
var childs = f.childNodes;

f.removeChild(childs[i]);
}

//这个方法是负责向接口请求数据的，你可以选择你喜欢的方式，我这里是直接用的mui.ajax
function getData(params){
mui.ajax("/article/getArticlePage",{
data:{
"header":{"os":"wap","app":"xxxx","ver":1.0},
"data":params
},
dataType:'json',
type:'post',
headers:{'Content-Type':'application/json'},
success:function(data){
mui('#refreshContainer').pullRefresh().endPullupToRefresh(true);
//下面这坨都是在拼dom 你可以用jquery 或者是你所熟悉的angular,vue双向绑定
var returnData = data.data;
var element=document.getElementById("list");
var para;
var node;
for(var i = 0; i<returnData.length;i++){
para = document.createElement("li");
node = document.createTextNode(returnData[i].article_title)
para.appendChild(node);
element.appendChild(para);
}
//这里很重要，这里获取页码 公式：总条数/每页显示条数
totalPage = data.ext%pager.size!=0?
parseInt(data.ext/pager.size)+1:
data.ext/pager.size;
if(totalPage==pager.page){//总页码等于当前页码，停止上拉下拉
mui('#refreshContainer').pullRefresh().endPullupToRefresh(true);
}else{
pager.page++;
mui('#refreshContainer').pullRefresh().refresh(true);
}
},
error:function(xhr,type,errorThrown){
//异常处理；
console.log(type);
}
})
}
</script>
</html>
The code has been posted but it doesn’t look very good
The following is the rendering. I wanted to make a video but found it was too useless to make it. It pissed me off
PS: Let me share with you a sample code: MUI pull-down to load more data
html code
<p id="pullrefresh" class="mui-content mui-scroll-wrapper">
<p id="mui-scroll" class="mui-scroll">
<ul id="refresh-ul" class="mui-table-view">
<!-- 内容 -->
</ul>
</p>
</p>
<script type="text/javascript">
mui('body').on('tap','a',function(){document.location.href=this.href;});//监听让页面A标签的超链接 是有效状态
mui.init({
pullRefresh : {
container:"#pullrefresh",//下拉刷新容器标识，querySelector能定位的css选择器均可，比如：id、.class等
up : {
height:50,//可选,默认50.触发下拉刷新拖动距离,
auto: true,//可选,默认false.自动下拉刷新一次
contentdown : "下拉可以刷新",//可选，在下拉可刷新状态时，下拉刷新控件上显示的标题内容
contentover : "释放立即刷新",//可选，在释放可刷新状态时，下拉刷新控件上显示的标题内容
contentrefresh : "正在刷新...",//可选，正在刷新状态时，下拉刷新控件上显示的标题内容
callback :function(){
//业务逻辑代码，比如通过ajax从服务器获取新数据；
//注意，加载完新数据后，必须执行如下代码，注意：若为ajax请求，则需将如下代码放置在处理完ajax响应数据之后
//mui('#refresh-ul').pullRefresh().endPullupToRefresh(); //refresh completed
var pagecount=$("#pagecount").val();
var page=$("#page").val();
pagecount=parseInt(pagecount);
page=parseInt(page);
page+=1;
$.ajax({
url:"/mobile/seckill/order/order_refresh_ajax.jhtml",
type: 'post',
datatype:'html',
data: {'pagecount': pagecount,'page':page},
async: false,//false代表只有在等待ajax执行完毕后才执行
success: function(data,msg){
$("#refresh-ul").append(data);
$("#page").val(page);
},
error: function(data,msg){
alert("error");
}
});
this.endPullupToRefresh(false);
} //必选，刷新函数，根据具体业务来编写，比如通过ajax从服务器获取新数据；
}
}
});
if(mui.os.plus) {
mui.plusReady(function() {
setTimeout(function() { mui('#pullrefresh').pullRefresh().pullupLoading(); }, 1000);
});
} else {
mui.ready(function() {
mui('#pullrefresh').pullRefresh().pullupLoading();
});
}
function goShoppingCart() {
window.location.href = "/mobile/seckill/shoppingcart.jhtml";
}
</script>
