问题 I have an iframe that takes up the entire window (100% wide, 100% high), and I need the main window to be able to detect when the mouse has been moved. Already tried an onMouseMove attribute on the iframe and it obviously didn't work. Also tried wrapping the iframe in a div like so: <div onmousemove="alert('justfortesting');"><iframe src="foo.bar"></iframe></div> .. and it didn't work. Any suggestions? 回答1: If your target isn't Opera 9 or lower and IE 9 or lower you can use css attribute

How frequently is D3 drag event triggered?

由 纵饮孤独 提交于 2019-12-24 11:07:19
问题 I have a very general low level question about dragging. I am specifically interested in learning what exactly determines when a drag event is triggered in D3.js v4. For example, if I move a dragged object very slowly, a drag event will fire each pixel I move. However, if I move fairly fast, the drag event is not triggered in a one-to-one correlation with the amount of pixels I have moved. I am currently researching this issue, primarily with the Chrome Dev Performance tab; I figure this will

Why does OnMouseMove fire repeatedly when the mouse is not moving in D2010?

由 99封情书 提交于 2019-12-22 04:21:51
问题 I'm porting a Delphi 5 app to D2010, and I've got a bit of a problem. On one form is a TImage component with an OnMouseMove event that's supposed to update a label whenever the mouse is moved over the image. This worked just fine in the original app, but now the OnMouseMove event fires constantly whenever the mouse is over the image, whether it's moving or not, which causes the label to flicker horribly. Does anyone know what's causing this and how to fix it? 回答1: My psychic debugging sense

JavaScript - mousemove event not triggered on iPad/iPhone

由 只谈情不闲聊 提交于 2019-12-13 07:19:34
问题 I worked for a while on E-learning project, where I had to script an HTML file that's loaded on a global framework. I used to use: $('#myobject').on('mousedown' ... 'mousemove' ... 'mouseup' , function(){} ) And it worked well everywhere (Chrome, IE, iOS ... etc) Now I am working on a personal project, and in the browser everything is working well, but 'mousemove' does not seem to get triggered on iDevices (iPad, iPhone ... etc). Here is simple code I wrote, that doesn't work on an iPad: $

See if left mouse button is held down in the OnMouseMove event

由 ぐ巨炮叔叔 提交于 2019-12-10 13:27:51
问题 How do I detect if the left mouse button is being held down in the OnMouseMove event for a control? 回答1: Your eventhandler for the OnMouseMove event should recieve a MouseEventArgs that should tell you if the left button is pressed private void mouseMoveEventHandler(object sender, MouseEventArgs e) { if(e.Button == MouseButtons.Left) { //do left stuff } else { // do other stuff } } 回答2: Simply have a boolean set to true when the left mouse button is held and set it to false when its released.
