滚动加载是个好东西,可以解决一次加载过多的尴尬,其实就是变相的分页,总结下这个轮子的用法,挺简单的。
首先是html结构:
<div> <div> <div> <ul> @foreach (var item in ViewBag.***) { if (item.IsPay == true) { <li> <div> <table> <tbody> <tr> <td>***</td> <td>@item.***</td> </tr> <tr> <td>***</td> <td>@item.***</td> </tr> <tr> <td>***</td> <td>@item.***</td> </tr> </tbody> </table> </div> </li> } } </ul> <div>加载更多</div> </div> </div>
然后是css样式:
#wrapper { position: absolute; z-index: 1; top: 0; bottom: 0; left: 0; width: 100%; overflow: hidden; } #scroller { position: absolute; z-index: 1; -webkit-tap-highlight-color: rgba(0,0,0,0); width: 100%; -webkit-transform: translateZ(0); -moz-transform: translateZ(0); -ms-transform: translateZ(0); -o-transform: translateZ(0); transform: translateZ(0); -webkit-touch-callout: none; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; -webkit-text-size-adjust: none; -moz-text-size-adjust: none; -ms-text-size-adjust: none; -o-text-size-adjust: none; text-size-adjust: none; } #more { text-align:center; }
需要的话,给父元素套上position:relative属性
最后是脚本中的初始化和获取数据:
var pagenum = 1, update = true, id=ID; var myScroll; setTimeout(function(){ myScroll = new IScroll('#wrapper', { mouseWheel: true, click: true }); myScroll.on('scrollEnd', function () { //console.log(this.y +"|||"+this.maxScrollY); //如果滑动到底部,则加载更多数据(距离最底部10px高度) if ((this.y - this.maxScrollY) == 0) { getMore(); } }); },100 ); function getMore() { var that = document.getElementById("more"); pagenum++; $.ajax({ url: '/***/getPage', data: {'currentPage':pagenum,'id':id}, type: 'POST', datatype: "json", success: function (data) { //alert(data); var list = data.List; if (list.length < 1) { pagenum--; that.innerHTML = "已经没有更多了..."; return; } var ul = document.getElementById("thelist"); for (var i = 0; i < list.length; i++) { var str = "<li>"; str += "<div class=\"panelListItemForALL\"><table class=\"allRecordTable\"><tbody><tr><td>***</td><td>"+list[i].OrderCode+"</td>"; str += "</tr><tr><td>***</td><td>"+list[i].GoodsName+"</td></tr>"; str += "<tr><td>***</td><td>"+ data.DatatimeArray[i] +"</td>"; str += "</tr></tbody></table></div>"; str += "</li>"; ul.innerHTML += str; myScroll.refresh(); } } }); }
把相应的数据填充进去就好,当然控制器里要写一个分页获取数据的方法,通过这里的ajax获取。
