现在已经不是纯Android独霸天下的时代了，H5嵌入Android的Hybrid混合开发是大势所趋。今天给大家带来的就是移动端中常见的“上拉刷新，下拉加载”特效，这个特效将会基于H5来实现。
先看下运行效果：
是不是有点小小的‘鸡冻' ，它就是由我们今天要介绍的主人公‘iscroll.js'实现的，接下来我以最最简便的方式教给大家~~
实现步骤
一、准备好iscroll.js库
到官网下载即可：
https://github.com/cubiq/iscroll
二、搭建页面结构
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta content="width=device-width, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0"> <meta content="yes"> <meta content="black"> <title>iScroll 实例：下拉刷新，滚动翻页</title> <style type="text/css" media="all"> body,ul,li { padding:0; margin:0; border:0; } body { font-size:12px; -webkit-user-select:none; -webkit-text-size-adjust:none; font-family:helvetica; } #header { position:absolute; top:0; left:0; width:100%; height:45px; line-height:45px; background-image:-webkit-gradient(linear, 0 0, 0 100%, color-stop(0, #fe96c9), color-stop(0.05, #d51875), color-stop(1, #7b0a2e)); background-image:-moz-linear-gradient(top, #fe96c9, #d51875 5%, #7b0a2e); background-image:-o-linear-gradient(top, #fe96c9, #d51875 5%, #7b0a2e); padding:0; color:#eee; font-size:20px; text-align:center; } #header a { color:#f3f3f3; text-decoration:none; font-weight:bold; text-shadow:0 -1px 0 rgba(0,0,0,0.5); } #footer { position:absolute; bottom:0; left:0; width:100%; height:48px; background-image:-webkit-gradient(linear, 0 0, 0 100%, color-stop(0, #999), color-stop(0.02, #666), color-stop(1, #222)); background-image:-moz-linear-gradient(top, #999, #666 2%, #222); background-image:-o-linear-gradient(top, #999, #666 2%, #222); padding:0; border-top:1px solid #444; } #wrapper { position:absolute; z-index:1; top:45px; bottom:48px; left:0; width:100%; background:#555; overflow:auto; } #scroller { position:relative; /* -webkit-touch-callout:none;*/ -webkit-tap-highlight-color:rgba(0,0,0,0); float:left; width:100%; padding:0; } #scroller ul { position:relative; list-style:none; padding:0; margin:0; width:100%; text-align:left; } #scroller li { padding:0 10px; height:40px; line-height:40px; border-bottom:1px solid #ccc; border-top:1px solid #fff; background-color:#fafafa; font-size:14px; } #scroller li > a { display:block; } /** * * 下拉样式 Pull down styles * */ #pullDown, #pullUp { background:#fff; height:40px; line-height:40px; padding:5px 10px; border-bottom:1px solid #ccc; font-weight:bold; font-size:14px; color:#888; } #pullDown .pullDownIcon, #pullUp .pullUpIcon { display:block; float:left; width:40px; height:40px; background:url(pull-icon@2x.png) 0 0 no-repeat; -webkit-background-size:40px 80px; background-size:40px 80px; -webkit-transition-property:-webkit-transform; -webkit-transition-duration:250ms; } #pullDown .pullDownIcon { -webkit-transform:rotate(0deg) translateZ(0); } #pullUp .pullUpIcon { -webkit-transform:rotate(-180deg) translateZ(0); } </style> </head> <body> <div> <a href="../db.html#page2">iScroll实例：下拉刷新，滚动翻页</a> </div> <div> <div> <div> <span></span><span>下拉刷新...</span> </div> <ul> <li>我是三冰 1</li> <li>我是三冰 2</li> <li>我是三冰 3</li> <li>我是三冰 4</li> <li>我是三冰 5</li> <li>我是三冰 6</li> <li>我是三冰 7</li> <li>我是三冰 8</li> <li>我是三冰 9</li> <li>我是三冰 10</li> <li>我是三冰 11</li> <li>我是三冰 12</li> <li>我是三冰 13</li> </ul> <div> <span></span><span>上拉加载更多...</span> </div> </div> </div> <div></div> </body> </html>
代码非常简单，无需多言，仅仅搭建一个静态结构而已~~
效果如下：
对照这个效果图看上面代码简直太easy，暂时与iscroll没有半毛钱关系，就是纯静态页面，此时你们唯一没有就是下面这个小图标，不用着急，文章最后会给到你的~~
