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");
            }
        });
