1，引入库文件fastclick.js
2，注入事件进去(body或者某个元素)
3，若使用jQuery
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script type="application/javascript" src="fastclick.js"></script>
</head>
<body>
<button id="click" >click me!</button>
<script type="text/javascript">
if ('addEventListener' in document) {
document.addEventListener('click', function(){
FastClick.attach(document.body);
}, false);
}
document.querySelector("#click").addEventListener("click",function(){
alert("click me!");
},false)
</body>
</html>
