DataTransferItem
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since November 2016.
* Some parts of this feature may have varying levels of support.
The DataTransferItem object represents one drag data item. During a drag operation, each DragEvent has a dataTransfer property which contains a list of drag data items. Each item in the list is a DataTransferItem object.
DataTransferItem was primarily designed for the HTML Drag and Drop API, and is still specified in the HTML drag-and-drop section, but it is now also used by other APIs, such as ClipboardEvent.clipboardData and InputEvent.dataTransfer. Documentation of DataTransferItem will primarily discuss its usage in drag-and-drop operations, and you should refer to the other APIs' documentation for usage of DataTransferItem in those contexts.
This interface has no constructor.
