问题 I have this code. $(document).ready(function() { $('#box').hide(); $(window).bind('scroll', function(){ if($(this).scrollTop() > 200) { $("#box").fadeIn(300); } else { $("#box").fadeOut(300); } }); }); So when I scroll down 200px it will make a div appear. When I scroll back up, it will disappear. This is fine, until I do it a lot. If I scroll up and down like a nutter the div keeps fading in and out even after I stop. This isn't related to just this instance, it's happened a lot in the past

问题 I just want the #menu to fade when the scroll bar is moving to provide a less cluttered interface. Is there code that would allow this? I guess basically what I'm looking for is how to grab the scroll bar movement event. To slowly fade out the #menu after 1 seconds of scrolling and bring back the #menu after 2 second of scroll-bar inactivity. Thank you so much! 回答1: var $menu = $("#menu"); var opacity = $menu.css("opacity"); var scrollStopped; var fadeInCallback = function () { if (typeof

问题 I've got class which inherits from JPanel with an image on it and i want to set up a little animation to display the panel/image and then fade it out when an event fires. I presumably set up a thread and fire off the animation but how do I do actually do the fade? 回答1: You can do the threading yourself, but it might be easier to use the Trident library to handle it. If you create a setter on your class called (say, setOpacity ), you can ask trident to interpolate the "opacity" field from 1.0

问题 I've asked this guestion before. But now I'll try to be a bit more specific. I've trying to make a background fade in when you mouse over a box. I've tried 2 different options. Option 1: Box1 is the box it mousesover, and hover1 is the new background that comes in. This actually works pretty well. However, it loads the acript, meaning, that if i just go crazy with my mouse over the box, the fadeing will continue endless, even when my mouse is standing still. Is there a way you can stop it?
