Drag-and-Drop Event

HTML drag-and-drop event attributes are used to handle user interactions related to dragging elements within a webpage. These events allow developers to create interactive interfaces where users can drag and drop content.

1. ondrag: Triggered when an element is being dragged.

<div draggable="true" ondrag="console.log('Element is being dragged!')">Drag me</div>

2. ondragstart: Fired when the drag operation starts.

<div draggable="true" ondragstart="console.log('Drag started!')">Drag me</div>

3. ondragend: Occurs when the drag operation ends, either successfully or unsuccessfully.

<div draggable="true" ondragend="console.log('Drag ended!')">Drag me</div>

4. ondragover: Triggered when a dragged element is over a valid drop target.

<div ondragover="console.log('Element is over the drop target!')">Drop here</div>

5. ondrop: Fired when a dragged element is dropped on a valid drop target.

<div ondrop="console.log('Element dropped!')">Drop here</div>
