DataTransfer.mozSetDataAt()
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.mozSetDataAt()
method is used to add data to a specific index in the drag event's data transfer
object.
A data transfer may store multiple items, each at a given zero-based index. mozSetDataAt()
may only be called with an index argument less than mozItemCount
in which case an existing item is modified, or equal to mozItemCount
in which case a new item is added, and the mozItemCount
is incremented by one.
Data should be added in order of preference, with the most specific format added first and the least specific format added last. If data of the given format already exists, it is replaced in the same position as the old data.
The data should be either a string
, a Boolean
or number type (which will be converted into a string) or an nsISupports
.

Example
This example shows the use of the mozSetDataAt()
