Hammer.js 移动端手势库，多点触控插件
jquery用法：
引入3个JS:
<script src="jquery.js"></script> <script src="hammer.js"></script> <script src="jquery.hammer.js"></script>
$(".myElement").hammer().bind("tap", function(ev) { $(this).addClass("red"); console.log(ev); }).bind("press", function(ev) { $(this).removeClass("red"); console.log("press"); });
//下面写在一起
拖动：
<div id="myElement" style="position:fixed;"> </div> var getCss = function(o,key){ return o.currentStyle? o.currentStyle[key] : document.defaultView.getComputedStyle(o,false)[key]; }; function drag(element){ element.style.top = getCss(element,"top"); element.style.left = getCss(element,"left"); var hammer = new Hammer(element);//hammer实例 var x = 0; var y = 0; hammer.on('panstart',function(event){ console.log("panstart"); x = parseInt(element.style.left); y = parseInt(element.style.top); }); hammer.on('panmove',function(event){ console.log("panmove"); element.style.top = y + event.deltaY + "px"; element.style.left = x + event.deltaX + "px"; }); hammer.on('panend',function(event){ console.log("panend"); }); } var myElement = document.getElementById("move-box"); drag(myElement);
一般用法：
<script src="hammer.js"></script> var myElement = document.getElementById('myElement'); var mc = new Hammer(myElement); mc.get('pan').set({ direction: Hammer.DIRECTION_ALL }); mc.on("panleft panright panup pandown tap press", function(ev) { if(ev.type == "press"){ obj.addClass("red") }else { obj.removeClass("red"); } });
