1抱歉回复晚了。看起来它只适用于iOS,而且它所做的只是:“touch Use momentum-based scrolling, where the content continues to scroll for a while after finishing the scroll gesture and removing your finger from the touchscreen. The speed and duration of the continued scrolling is proportional to how vigorous the scroll gesture was. Also creates a new stacking context.”因此你最好不要使用它。 - Marco
