问题 I've written a web-app in HTML and Javascript for iPhone and Android which involves the dragging and dropping images. You initiate the drag by holding your finger over the image for about a second. However, Android then pops up the message giving me the option to save the image, set it as wallpaper etc. How can I prevent Android from doing this? Is there a metatag I can use? Some javascript? 回答1: Javascript has a function to prevent the default action of a browser for the event in question.

问题 I'm using Full Calendar with draggable events. I have specified a url in the event object which causes the event to link to a page. Whenever I drag an event in IE or Chrome, the click event does not fire (that's good). But it does in Firefox. There is an event called eventClick provided by Full Calendar but apparently that doesn't fire before the hyperlink redirects. Is there some way to prevent drags from firing the click event without using some jQuery hack? 回答1: The problem is with event

问题 I'm posting this along with the best answer I have come up with. I haven't found any similar questions, so here goes. When a input of type checkbox is converted to a jquery ui button, I have observed (as have others) that it only registers a click if the mouse is kept completely still while clicking. Any movement what-so-ever and nothing happens. To the user this can only be perceived as flaky and unreliable behavior. How do others work around this behavior (observed with jquery 1.6.3/jquery

问题 So I was spending some time playing around with pure (no external libraries) SVG elements dragging. In general all works, but there is this nasty issue for fast moving mouse: - when user mousedowns a draggable SVG element close to its edge - then drags (mousemove) such draggable too fast - the mouse "loses" the draggable Here the issue is described in more details: http://www.svgopen.org/2005/papers/AdvancedMouseEventModelForSVG-1/index.html#S3.2 Also here the author tried to fix UX by

问题 I have a simple JEditorPane inside a JScrollPane that displays line numbers on the left side. It works great except when you move the window off screen and pull it back again, it looks the this when you stop dragging: any ideas? Should I need to be listening for a move/drag event and calling repaint/revalidate somewhere? Thought it might be something obvious, but here is some code. I am using the JSyntaxPane. public EditorPanel() { this.setLayout(new BorderLayout()); PythonSyntaxKit.initKit()

问题 I implemented something in Windows Forms similar to DragMove but with boundaries set to 10 units of the margins of the primary screen. When switching over to WPF I found this thread to be useful in achieving the same result. However, since this is a post-move event, what happens is that if my window is dragged beyond the boundaries I set, it "jumps" back. I would like to avoid this effect as it looks terrible. Is there a simple way to avoid the window to be moved outside a given area without

问题 I am trying to drag two objects simultaneously with multitouch in AS3. My goal is to have the user pinch the two objects together. Right now I cannot get both to be moving at the same time. Any ideas why this isn't working? Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT; // bullseye4a.addEventListener(TouchEvent.TOUCH_BEGIN, fl_ClickToDrag4a); function fl_ClickToDrag4a(event: TouchEvent): void { bullseye4a.startDrag(); } bullseye4b.addEventListener(TouchEvent.TOUCH_BEGIN, fl

问题 I have this formula in Excel, in row E5: =SUM(Banco!H$5;Banco!H$6;Banco!H$8;Banco!H$9;Banco!H$10;Banco!H$11) I need it to change the COLUMN references instead of ROWS when I drag it down (basically behave like I was dragging it across)... For example: =SUM(Banco!I$5;Banco!I$6;Banco!I$8;Banco!I$9;Banco!I$10;Banco!I$11) =SUM(Banco!J$5;Banco!J$6;Banco!J$8;Banco!J$9;Banco!J$10;Banco!J$11) =SUM(Banco!K$5;Banco!K$6;Banco!K$8;Banco!K$9;Banco!K$10;Banco!K$11) Any clues? Thanks a lot! 回答1: ... Use the

问题 I'm trying to implement drag and drop sorting in listview on my vba form. I found many solutions for vb forms. But they doesn't work in vba. I also found one article for vba and it almost works. But problem is that when I drag item my cursor doesn't highlight other items when mouseover. It only highlight 1st line when I drag item below last line. Here is 2 screenshots for better explanation. And here is code: Public Sub LVDragDropSingle(ByRef lvList As ListView, ByVal x As Single, ByVal y As
