IE
Chrome executes click and cancel events, while IE executes two click events. What's going on? Please give me some guidance! ! !
Thank you in advance, brother!

IE may differentiate between single and double clicks. If you double-click, it will be processed in the same way as single-click, and it will not become canceled the second time. If the time interval is large enough, the system will think it is two clicks, and this will not happen.
