iscroll5实现下拉加载更多
1 下载最新的iscroll5,本文版本是5.1.3
2 提取iscroll-probe.js,选择这个文件的原因是我们要给iscroll扩展一个事件,需要用到probeType 属性
3 修改iscroll-probe.js的源码,添加上拉监听事件slideUp (

4 编辑页面
Html:
"<div id=\'lookupScrollerWrapper\'>"+ "<div>"+ "<div>"+ "<ul data-role=\'listview\' id=\'assListId0000\'></ul>"+ "</div>"+ "<div id=\'lookupScrollerPullUp\' style=\'display:none\'>"+ "<span>上拉加载更多</span>"+ "</div>"+ "</div>"+ "</div>"
css:
#lookupScrollerWrapper { position: absolute; top: 54px; bottom: 0px; width: 100%; overflow: hidden; } #lookupScrollerPullUp { height: 40px; line-height: 40px; font-size: 12px; font-weight: bold; color: grey; text-shadow: none; text-align:center; position:absolute; width:100%; bottom:-40px; }
js:
lookupScroll = new IScroll(\'#lookupScrollerWrapper\', { probeType: 3, mouseWheel: true, click: true }); lookupScroll.on("scroll", function() { if(this.maxScrollY - this.y >= 40){ $("#lookupScrollerPullUp").css("display", ""); } }); lookupScroll.on("slideUp", function() { if(this.maxScrollY - this.y >= 40) { this.scrollTo(0, this.maxScrollY-47, 3000, IScroll.utils.ease.back); $(this)._associateKey(); } }); $(\'#lookupScrollerWrapper\').on(\'touchmove\', function(){ if(lookupScroll.maxScrollY - lookupScroll.y >= 40){ $(\'#lookupScrollerPullUp\').html("释放加载更多"); } }); $(\'#lookupScrollerWrapper\').on(\'touchend\', function(){ if(lookupScroll.maxScrollY - lookupScroll.y >= 40){ $(\'#lookupScrollerPullUp\').html("正在加载.."); } else { $(\'#lookupScrollerPullUp\').html("上拉加载更多"); } });
6 如果页面是动态编辑的,则要调用刷新的代码,否则页面不会滚动
lookupScroll.refresh();
