jQuery - Animation transition interrupted by hover

阅读更多关于 jQuery - Animation transition interrupted by hover

问题 I have created a div to slide in from outside of the viewport and place itself over the original div. The animation is triggered by hovering over box1 . This will bring box2 in place of box1 . When the mouse leaves the box2 div, it will be placed outside of the viewport again. However, slow cursor movement within this div will result in animation triggering rapidly. $(document).ready(function() { $('.box1').mouseover(function() { $('.box2').stop().animate({ top: 0 }, 100); }).mouseout

问题 I'm making a React-Native app and the scenario is this: I want the user to be able to pan a view, but not wholly the way he wants. I'd like to constraint how much the view can move when being dragged by the user. I've read through the documentation of both the PanResponder and Animated API (multiple times), but can't find anything that does this, neither can I find anyone else that implemented something alike. Constraining in the panresponder's event? onPanResponderMove: Animated.event([null,
