jquery using Slidedown and Slideup to do two-level menu ideas to solve

When navigating, you will encounter a mouse move quickly, move quickly, and then you will find that the menu is gradually disappearing, the last move up or even do not show.

Just change the first stop () inside to stop (true,true). The second stop () is removed. or add Stop (true,true) to the second one, and the first one is removed.

Or use a function like this: Change the first stop () to filter (': Not (: Animated) '). The same second one does not need to add stop ().

What is involved in this is actually an animated stop ();

The Stop () method stops the animation that is currently running.
$ (selector). Stop (stopall,gotoend)
StopAll is optional. Specifies whether to stop all queue-join animations for the selected element.
Gotoend is optional. Specifies whether to allow the current animation to be completed. This parameter can only be used when the StopAll parameter is set.

As can be seen from the Stop () above, we have triggered the slidedown () when we have slipped, so that his height naturally completes the current animation and stops the added animation queue.

ulobj.animate ({height: ' Toggle ', opacity: ' Toggle '}, speed);
