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.
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
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.
Note: This method is Gecko-specific.
