jQuery mouseup not being detected correctly

问题:

I have a div that contains a span. I have a mouseup, and mousedown event that should fire when pressing in the div. However it doesn't work correctly.

Please go to this fiddle: http://jsfiddle.net/Ym7rM/

If you select the text and then try to drag it, it just detects the mousedown event,but not the mouseup.

What am I doing wrong? I'm using Chrome.

Thanks

EDIT:

Sorry, I simplified the question, see the new fiddle.

回答1:

The mouseup event is being detected correctly; it's just that the browser is not firing a mouseup event after you perform a drag. This is an intentional behavior by the browser. You should also listen for the dragend event if you want to include the behavior that you are intending now.

the mouseup event is fired only inside the orange div. thats what you coded. try this http://jsfiddle.net/ur8J9/5/
