移动端兼容判断单击和双击事件

移动端兼容判断单击和双击事件，费话不想说了，直接上代码：

<input name="double_click" id="double_click" type="hidden" value="" />
            
<script>
	//兼容移动端焦点定位，主要用于兼容安卓班牌的触屏
	$(function() {
		//console.log($('.box'));
		
		function double_click(){
			setTimeout(function() {
				$("#double_click").val('')
			}, 500)
		}
		
		//此处与双击冲突，都会造成，改成任意位置长按，
		$("body").on({
			touchstart: function(e) {
			
				clickd_id=$(e.target).attr("id");
				console.log(clickd_id+"1")
				
				vvl=$("#double_click").val();
				
				if (vvl=='1'){
					//console.log("双击")
					
					if (clickd_id=='anniu_index'){
						system_out()
					}
				}else{
					//console.log("单击")
				}

				$("#double_click").val('1')
				double_click();
				
				$("#xueyuan_card").focus()
				
				//长按触发事件
				timeOutEvent = setTimeout(function() {
					timeOutEvent = 0;
					$("#xueyuan_card").focus()
				}, 1000)
			},
			touchmove: function(e) {
				
				//clickd_id=$(e.target).attr("id");
				//console.log(clickd_id+"2")
				
				clearTimeout(timeOutEvent);
				timeOutEvent = 0;
				$("#xueyuan_card").focus()
			},
			touchend: function(e) {
				
				//clickd_id=$(e.target).attr("id");
				//console.log(clickd_id+"3")
				
				clearTimeout(timeOutEvent);
				if (timeOutEvent != 0) {
					$("#xueyuan_card").focus()
				}
				return false;
			}
		});
	});
</script>
