javascript - 触摸屏激活时 onmousedown 和 onmouseup 不起作用
我有两个按钮,它们应该用作我网页上游戏的触摸屏控件,每个按钮在按住时将桨向一个方向移动,并且它们都完全按照它们应该做的,但只有当它们是在电脑上被鼠标点击。所有其他按钮在触摸屏上单击时都会起作用,但没有一个使用 onmousedown 和 onmouseup。任何人都知道发生了什么以及如何解决它?
testing - 如何在Testcafe中只拖放而不拖放
所以我有一个场景,每当我将一个元素拖到另一个元素时,我想捕获一个弹出元素消息。

delphi - Why is FMX TScrollBar OnMouseUp not working?
I have a ScrollBar with mouse events assigned to onChange, onMouseWheel and onMouseUp. The onChange and wheel events work fine, but the onMouseUp event does not fire. Drilling down to the TControl method on debug, I noticed that the event variable (FOnMouseUp) is nill. The event is assigned in the IDE and I put it in the onCreate event of the form, plus I tried assigning it in various other places after the form is created, but to no avail. What gives?
Here is a simple reproducible example, in which all three scroll bar mouse events do not fire:

javascript - 无库拖动后 Mouseup
我有一些纯 css 快照滚动功能,我想在用户停止拖动后检测元素相对于视口的位置。问题是我不想使用一些花哨的库,因为我不需要实际移动或放下东西。我只是不想在 mouseup 上触发事件。我的问题是,在按下鼠标左键的同时移动光标后,mouseup 事件不会触发。顺便提一句。我正在使用 Vu3
<span id="handle" class="card-handle" onmouseup="myMethod"></span>
我希望找到一个轻量级的解决方案,因为我真的不需要所有这些拖动功能
