tinyscrollbar  

//方法1
var _this = $('#fabu');
var scrollFunc=function(e){
    e=e||window.event;
    if(e.wheelDelta){//IE/Opera/Chrome
        if(e.wheelDelta==-120){
            _this.hide();
        }else{
            _this.show();
        }
    }else if(e.detail){
        //Firefox
        if(e.detail==-3){
            _this.hide();
        }else{
            _this.show();
        }
    }
};
if(document.addEventListener){//注册事件
    document.addEventListener("onmousewheel" ,scrollFunc, false);
}
//IE/Opera/Chrome
window.onmousewheel=document.onmousewheel=scrollFunc;

//方法----------稍微有点动画

 //发布按钮上滑消失，下滑出现
            var startY, endY;
            document.addEventListener('touchstart', function (e) {
                startY = e.touches[0].pageY;
                console.log(startY)
            }, false);
            document.addEventListener('touchmove', function (e) {
                endY = e.changedTouches[0].pageY;
                moveLoad();
            }, false);
            function moveLoad() {
                    var movY = endY - startY;
                    var fabu = document.getElementById('fabu');
                    if (movY > 0) {
                        jQuery("#fabu").animate({bottom:"10px"},0.1).fadeIn(50);

                    }

                    }
            }

//方法2
function getData(event) {
    var e = event || window.event;
    //获取滚动距离(FF每次滚动 data为3或者-3，其他为120或者-120  等于3是向上滚动，等于-3是向下滚动)
    var data = e.detail || e.wheelDelta;
    if(data==3){
        _this.hide();
    }else if(data==-3){
        _this.show();
    }
}
//IE之外的绑定事件方法
if (document.addEventListener && !document.attachEvent) {
    document.addEventListener('mousewheel', getData);
    //FF绑定滚动事件
    document.addEventListener('DOMMouseScroll', getData);
}
//IE
else if (document.attachEvent && !document.addEventListener) {
    document.attachEvent('onmousewheel', getData);
} else {
    window.onmousewheel = getData;

//方法3 手机端滑动监听事件
//发布按钮上滑消失，下滑出现
//var _this = $('#fabu');

},false);

    var movY=endY-startY;
    if(movY<-80){
        //_this.hide();
        alert(123)
    }else{
        //_this.show();
