mui的swipeup和swipedown的事件同时执行

videoul.addEventListener("hold",function(){  

                    mui(".videoul").on('swipeup',".videoul",function(){  
                        console.log("上滑")  
                        var tops = parseInt(videoul.style.marginTop)-100  
                        // console.log(tops)  
                        videoul.style.marginTop = tops+'vh'  
                    });  
                    mui(".videoul").on("swipedown",".videoul",function(){  
                    console.log("下滑")  
                    var tops = parseInt(videoul.style.marginTop)+100  
                    // console.log(tops)  
                    videoul.style.marginTop = tops+'vh'  
                })
