　　（3）判断

            if(/((iPhone|iPad|iPod)/i.test(navigator.userAgent)){
                $("#onepic_sum").css("font-size","18px");
                $("#FS_arr_left_01").show();
                $("#FS_arr_right_01").show();
            }

（4）生成随机数

        //生成随机数
        function random(min,max){
            return Math.floor(min + Math.random()*(max - min));
        }

（5）手机端滑动 可判断左划右划（横向）、纵向

		console.log(coverpage);
		var touchInfo = new Object();
		touchInfo.iPadStatus = 'ok';
		var touchstart = function(e){
			//e.preventDefault();

			touchInfo.iPadScrollX = window.pageXOffset;
			touchInfo.iPadScrollY = window.pageYOffset; //用于判断页面是否滚动
			console.log(touchInfo.iPadLastX,touchInfo.iPadScrollX,touchInfo.iPadScrollY);
		};
		var touchend = function(e){
			//e.preventDefault();
			if(touchInfo.iPadStatus != 'touch'){return};
				 touchInfo.iPadStatus = 'ok';
				//self._state = 'ready';
				var cX = touchInfo.iPadX - touchInfo.iPadLastX;
			if(cX<0){//左划

			}else{//右划

			};
		};
		var touchmove = function(e){
			e.preventDefault();
			if(e.touches.length > 1){ //多点触摸
			touchend(e);
			};
			touchInfo.iPadX = e.touches[0].pageX;
