jquery 区分click 和doubleClick 事件

var time = null;
		$('#testClickAndDoubleClick').click(function () {
		    clearTimeout(time);
		    time = setTimeout(function(){
		        alert("单击")
		    },300);
		});

		$('#testClickAndDoubleClick').dblclick(function () {
		    clearTimeout(time);
		    alert("双击")
		});
