我现在有一个函数，用来使页面左右滑动。但是现在出现一个问题，滑动的场景有两个，一级菜单和二级菜单。现在如果用在一起的话，一级菜单滑动完以后数值会保存，当点入二级菜单以后使用之前的状态。如何可以将这个事件给拷贝或者各自不影响呢？

 $(el).on("touchstart", function(e) {
        var targetTouches = e.originalEvent.targetTouches;
        old_x = parseInt(targetTouches[0].pageX);
        _click = 1;
        var num = $(this).find("li").length;
        switch (true) {
            case num<=4:
            huadong = 1;
                break;
            case num > 4&&num <= 8:
            huadong = 2;
                break;
            default:
                huadong = 3;
                break;
        }
    }).on("touchend", function(e) {
        _click = 0;
        if(move == -1){
            if(jishu < huadong){
                jishu++;
                baifen-=parseFloat(100/huadong); 
                $(this).css({
                    "transform": "translateX("+baifen+"%)",
                    "transition": "all .5s"
                })
            }
        }else if (move == 1){
            if (jishu > 1) {
                jishu--;
                baifen += parseFloat(100/huadong);
            $(this).css({
                "transform": "translateX("+baifen+"%)",
                "transition": "all .5s"
            })
            }
        }
    }).on("touchmove", function(e) {
        var targetTouches = e.originalEvent.targetTouches;
        new_x = parseInt(targetTouches[0].pageX);
        if (_click == 1) {
            if (new_x - old_x < 50) { //向前
                move = -1;
            } else if (new_x - old_x > 50) {
                move = 1;
            } else {
                move = 0;
            }
        }
    })
