DataTransfer.mozClearDataAt()
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The DataTransfer.mozClearDataAt()
method removes the data associated with the given format for an item at the specified index. The index must be in the range from zero to the number of items minus one.
If the format
argument is not provided, then the data associated with all formats is removed. If the format is not found, then this method has no effect. If the last format for the item is removed, the entire item is removed, reducing mozItemCount
by one.
Removing the last format for a particular index removes that item entirely, shifting the remaining items down and changing their indices.
