弃用
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

DOM DOMMouseScroll event is fired asynchronously when mouse wheel or similar device is operated and the accumulated scroll amount is over 1 line or 1 page since last event. It's represented by the MouseScrollEvent interface. This event was only implemented by Firefox. You should instead use the standard wheel 事件。

冒泡	Yes
可取消	Yes
接口	MouseScrollEvent

If you want to prevent the default action of mouse wheel events, it's not enough to handle only this event on Gecko because If scroll amount by a native mouse wheel event is less than 1 line (or less than 1 page when the system setting is by page scroll), other mouse wheel events may be fired without this event.

On Gecko 17 (Firefox 17) or later, you need to call preventDefault() of wheel events which must be fired for every native event.

Use the standardized wheel event if available.

特性

The event has only one additional property beyond standard events.

detail

detail property describes the scroll more precisely, with positive values indicating scrolling downward and negative values indicating scrolling upward.

If the event represents scrolling up by a page, the value of detail is -32768. If the event indictes scrolling down by a page, the value is +32768. Any other value represents the number of lines to scroll, with the direction indicated by the value's sign.

注意： Trusted events are never sent with a value of 0 for detail .

Trusted events are never fired with 0.

注意 : If the platform's native mouse wheel events only provide scroll distance by pixels, or if the speed can be customized by the user, the value is computed using the line height of the nearest scrollable ancestor element of the event's target. If that element's font size is smaller than mousewheel.min_line_scroll_amount , that preference's value is used as the line height.
