jQuery.removeData()

Categories: Data | Utilities Chinese Translation: jQuery.removeData()

jQuery.removeData( element [, name ] )Returns: jQuery

Description: Remove a previously-stored piece of data.

Note: This is a low-level method, you should probably use .removeData() instead.

The jQuery.removeData() method allows us to remove values that were previously set using jQuery.data(). When called with the name of a key, jQuery.removeData() deletes that particular value; when called with no arguments, all values are removed.

Example:

Set a data store for 2 names then remove one of them.
