Examples

1. Remove specific key

$('div').data('id', 123);

2. Remove all data

$('div').removeData();

Result

// All internal cached data for the element is cleared.

3. Remove multiple keys

$('div').data({ id: 1, role: 'user' });
$('div').removeData('id role'); // or ['id', 'role']

Result

// $('div').data() would return {}.
