.removeData( [name ] )Returns: jQuery
Description: Remove a previously-stored piece of data.
version added: 1.2.3.removeData( [name ] )
nameType: StringA string naming the piece of data to delete.
version added: 1.7.removeData( [list ] )
listAn array or space-separated string naming the pieces of data to delete.
.removeData() method allows us to remove values that were previously set using
.data(). When called with the name of a key,
.removeData() deletes that particular value. When called with no arguments,
.removeData() removes all values.
.removeData() will only remove data from jQuery's internal
.data() cache, and any corresponding
data- attributes on the element will not be removed. A later call to
will therefore re-retrieve the value from the
data- attribute. To prevent this, use
.removeData() to remove the
data- attribute as well. Prior to jQuery 1.4.3,
data() did not use
data- attributes, this was not an issue.
As of jQuery 1.7, when called with an array of keys or a string of space-separated keys,
.removeData() deletes the value of each key in that array or string.
Set a data store for 2 names then remove one of them.
