由于容器隐藏横向滚动条后，移动端横向滚动效果不受影响，但是pc端是无法通过鼠标进行横向滚动，因此需要自己手动实现效果。

draggable="false"，通过设置draggable，是可以设置html不允许拖拽效果，通过拖拽可以初步实现pc端横向滚动行为。
- draggable的兼容性是最好HTML属性
- css样式-webkit-user-drag: none;也可以实现类似效果，兼容性不太好，移动效果大部份都有效
user-select:属性可以设置是否允许用户选择页面中的图文内容
mousedown和mouseup：通过设置鼠标事件，实现鼠标按下后，坐标位置不一样，让容器调用scrollTo就可以实现滚动效果。
wheel：通过滚动事件，在容器内滚动滚轴可以横向滚动
getBoundingClientRect，记录每个图标的x位置，通过前后位置是否变化，如果不变化,鼠标单击的时候就可以触发单击事件。因为mousedown事件发生也会触发click事件

class Scroller {
    init() {
        this.setDragWheelEvent(".gameShow");
        this.setDragScrollEvent(".gameShow");

            if (!inThrottle) {
                fn.apply(context, args);
                lastTime = Date.now();
                inThrottle = true;
            } else {
                clearTimeout(lastFn);
                lastFn = setTimeout(function () {
                    if (Date.now() - lastTime >= wait) {
