MDN wants to learn about developers like you:


The DataTransferItem object represents one drag data item. During a drag operation, each drag event has a dataTransfer property which contains a list of drag data items. Each item in the list is a DataTransferItem object.

This interface has no constructor.


DataTransferItem.kind Read only
The kind of drag data item, string or file.
DataTransferItem.type Read only
The drag data item's type, typically a MIME type.


Returns the File object associated with the drag data item (or null if the drag item is not a file).
Invokes the specified callback with the drag data item string as its argument.
Returns an object based on FileSystemEntry representing the selected file's entry in its file system. This will generally be either a FileSystemFileEntry or FileSystemDirectoryEntry object.


All of this interface's methods and properties have their own reference page, and each reference page has an example of its usage.
