scroll

问题 I have a spark List with an item renderer and a tile layout. If I scroll by clicking with the mouse on the scroll bar and trying to scroll with the mouse wheel after that, there is a problem: The interval of the scrolling is oversized, instead of scrolling one item down (or up) the List scrolls 4 items down (or up). <s:List dataProvider="{myDataProvider}" itemRenderer="MyRenderer" left="11" right="11" bottom="3" top="10" useVirtualLayout="false" > <s:layout> <s:TileLayout columnAlign=

问题 My listview keeps changing while scrolling. I'm trying to display the messages in "messages" variable. Everything is fine when i scroll first time.

问题 I am using jQuery UI Accordion. One section has a scroll bar. I would like that scroll bar to default to the top every time that section is opened. Currently, it "remembers" its previous position. Is there a way to make it forget its position or always default to the top. I only want to set this for the particular section, not the entire page. This post suggests using window.scrollTo(0, 0); to force the page to scroll to the top. But I'm unsure how to apply that to only a particular section.

问题 I've come down to this interesting (and annoying) Firefox feature while implementing parallax scrolling on one of the supported sites. Strangely, Firefox (version 8.0) performed worst of all browsers, with even IE8 being ahead. After some investigation, I've figured out that FF plainly stops Javascript execution until the scrolling has stopped. The example can be seen here: http://jsfiddle.net/svd53/. Just try to pan the scrollbar slowly in one direction and pay attention to the counter. Any

问题 My client wants to add a search box on specific pages that will allow their user to search for a product and it will scroll to that text. This way it's easier for her to direct her clients to the right part of the page. This is easily done using Ctrl-F with the browsers search function. Unfortunately the client wants the search to be part of the site. Any advice on how to accomplish this? I've struggled to find a wordpress plug-in and any JQuery code I've used around the internet has failed

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: ScrollTop really jerky in Chrome I'm using the following code to get a back to top button and a navigation to fade in once the user scrolls. The problem is its triggering every time you scroll, therefore causing the scrolling to be really jerky. Is there an alternate way to do this, which would maybe trigger the function only once? $(function () { $(window).scroll(function () { if ($(this).scrollTop() > 600) { $

问题 Cell doesn't receive touch events, when there is UIScrollView inside UITableViewCell. Is there any way to cancel tap events for UIScrollView (needs only to handle scrolling)? 回答1: If you need touches to go through, implement a subclass of UIScrollView, and add these: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { // Pass to parent [super touchesBegan:touches withEvent:event]; [self.nextResponder touchesBegan:touches withEvent:event]; } - (void)touchesEnded:(NSSet *)touches
