drag-and-drop

问题 Long-pressing images or links in a WKWebView on iOS 11 and 12 initiates a Drag & Drop session (the user can drag the image or the link). How can I disable that? 回答1: I did find a solution that involves method swizzling but it's also possible to disable drag and drop in a WKWebView without any swizzling.

问题 I am attempting to do a simple drag and drop from one column to another. I am copying the element so that the list on the right can have multiple versions of the element on the left. Don't worry, I'm setting unique IDs before the actual append. However I also want the user to be able to drag out of the box to delete that same object.

问题 I would like to create draggable (free) buttons in Ionic. In ionic 3 I used a directive to do this (link https://www.joshmorony.com/building-an-absolute-drag-directive-in-ionic-2/) but this directive don't works in ionic 5 and it does not give any errors.

问题 I'm trying to move an element by watching mousemove events on the document while the element is being dragged (using html5 drag and drop). I added a mousemove listener on the document on a parent element that fires whenever I move my mouse, but once I start dragging another child element I stop seeing mousemove events and once I stop dragging I see the events again. I don't see it anywhere in the API (https://developer.mozilla.org/en-US/docs/Web/Events/mousemove) that dragging disables these
