mouseevent

问题 I want to achieve an horizontal click and dragg website, it works perfectly in Chrome but not in Firefox. My problem : Click and dragg on links in Firefox is making the stop-icon appears next to the cursor and then blocking mouseup event. What I know : The problem is only appearing on links and I found this post (javascript and dragging in firefox) that is suggesting to use addEventListener on the document , but it didn't fix it. Old code below (to see the updated one go on codepen) const

问题 What I want is : when mouse points on a div, page's scroll bar doesn't scroll. Is this impossible? When I do this, the page's scroll bar always scrolls. Here is a piece of the javascript code: if(document.addEventListener){ document.addEventListener('DOMMouseScroll',scrollFunc,false); } window.onmousewheel=document.onmousewheel=scrollFunc;//IE/Opera/Chrome/Safari How to do that? 回答1: Here you go: var noscroll = document.getElementById('noscroll'); var locked, lockedX, lockedY; noscroll

问题 The MDN documentation is quite scant. Cannot find much else about setCapture elsewhere. Can somebody please provide a general explanation of the method and also explain what it means by 'retargeting all mouse events to the given element'? 来源： https://stackoverflow.com/questions/45070624/element-setcapture

问题 I'm trying to simulate movement with Parallax.js in order to test for ways to improve its performance. But how do I loop back and forth between 0 , 0.5 and 1 on Parallax.js' originX and originY in a way that would cause a circular motion? http://jsfiddle.net/frank_o/amvvkm9z/ Pseudo-code: var scene = $('#scene'); scene.imagesLoaded(function() { var circularMovement = [ [0,0], [0.5,0], [1,0], [1,0.5], [1,1], [0.5,1], [0,1], [0,0.5] ]; // Initiate Parallax scene.parallax({ originX: 0, originY:

问题 I have been working with simulating mouse events with the Robot class for a while, and all was well, until I tried to scroll using the mouseWheel function. I just have this simple line: Robot robot = new Robot(); robot.mouseWheel(-100); I have been trying variations of this for a long time, and the program runs, does nothing, then terminates normally. Can someone shed light on why this is? Thanks! 回答1: Your program might not be working because either there is nothing to scroll up on the GUI

问题 I am working with the example below. And I have a difficulty. Necessary to make the balls escape the mouse pointer. Change direction when they find the pointer. I tried to pass as a parameter to the mouse position to the function "move" but get an error: "Exception in thread" Thread-2 "java.lang.NullPointerException" Can anyone give me a hint how to do this? I'm lost. Code: public class SimpleBalls { private Point mousePoint; public static void main(String[] args) { new SimpleBalls(); }

问题 I have a PictureBox that is inside a TabPage , and of course this TabPage is part of a TabView and this TabView is inside a Form . I want users be able to move this picture box within the tab page. For this I am using the MouseDown , MouseMove and MouseUp events of the picture box: private void pictureBoxPackageView_MouseDown(object sender, MouseEventArgs e) { if (!_mapPackageIsMoving) { _mapPackageIsMoving = true; } } private void pictureBoxPackageView_MouseMove(object sender, MouseEventArgs

问题 I have some top decoration pane, which I want to process/preprocess mouse events, but which should not consume them, i.e. all overlapped panes should work as if they were not overlapped by decoration pane. How to do this? I failed with several tries. Below is a code with 3 panes. Green one is "decorating". The task is to make it transparent to mouse events. Yellow and blue panes are worker panes. They should work as if they were not overlapped by green pane. But green pane should receive

问题 I have a 3D game, and every time I move the cursor, I want it to reset to the middle. Problem is that robot.mouseMove() calls MouseEvent (It does make sense) and resets the position and so I can't rotate. Thank you! 回答1: Because Robot is generating a native event, the event will (eventually) make it's way to the Event Queue for processing by the EDT. This means if you try and do something like... removeMouseListener(...); Robot.mouseMove(...); addMouseListener(...); It will, basically, have

问题 I'm trying to make Drag and Drop functionality on my own without use any opensource modules. When I use single element and create Observables in the controller like: const mouseup = Observable.fromEvent(item, 'mouseup'); const mousemove = Observable.fromEvent(document, 'mousemove'); const mousedown = Observable.fromEvent(item, 'mousedown'); Drag works fine. But when I bind event in template with (click) and pass $event to controller like: (click)="click($event)" I can't convert event into
