由 纵然是瞬间 提交于 2021-02-10 16:10:25
问题 I'm looking for an automatic drag and dropper. First, when I click anywhere on the screen, get coordinates, then drag and drop an element with the ID of "ball". using jQuery OR javascript. I coded a similar script to what I want, but this script got patched when the website's client got updated. This one automatically dragged and dropped when I pressed key 1 (keycode 49), (function () { 'use strict'; var mouseX = 0; var mouseY = 0; var invName = ''; var timer = 0; document.body

NSLayoutManager returns incorrect glyphIndex for mousePosition in NSTextView

由 半世苍凉 提交于 2020-08-09 08:08:37
问题 I have an NSTextView subclass as the right item in an NSSplitViewController , the left panel is an NSOutlineView . To process mouse clicks while the command key is pressed in the text view, I added the following to find the glyph that is under the mouse: override func mouseDown(with event: NSEvent) { guard let lm = self.layoutManager, let tc = self.textContainer else { return } let localMousePosition = convert(event.locationInWindow, to: nil) var partial = CGFloat(1.0) let glyphIndex = lm

hover style can not apply when press mouse button in chrome

由 寵の児 提交于 2019-12-30 18:51:11
问题 All: [UPDATE] I find another way to implement this, not solution, but just a working trick: Use mousedown as a event trigger(because I need a drag action, so there should be a mousedown event anyway), inside that, bind mouseover event to that span(I do not know why, but bind mouseover inside mousedown can make mouseover work on span) , give it a new class which change the background color; The problem I had with Chrome 40 is: I set a style: span { background-color:red; } span:hover {

Mousedown Timer using JavaScript/jQuery

由 孤街醉人 提交于 2019-12-28 06:54:12
问题 How can I know how long a user has been holding the mouse button down (anywhere on a webpage)? I want to execute a function when the user held the mouse button for at least 2-3 seconds (preferably cancelling the mouse down in the process). Is this possible? 回答1: Here you go: $(window).mousedown(function(e) { clearTimeout(this.downTimer); this.downTimer = setTimeout(function() { // do your thing }, 2000); }).mouseup(function(e) { clearTimeout(this.downTimer); }); Live demo: http://jsfiddle.net
