In jQuery, event namespaces are related to a particular feature of the
unbind() methods. These methods accept a period-separated list of event namespaces attached to the main event name. Without namespaces, you're forced to remove a given event handler in this way:
Instead, you can use event namespaces as follows:
$(element).bind('click.myEvent', handler); $(element).unbind('click.myEvent');
Using namespaces, you're not forced to refer directly the handler passed to these methods, but only its namespace. You can remove multiple handlers with namespace as once:
The syntax used here is much similar to the syntax used for CSS classes. You can even remove a namespace handler without specifying the type of event you're using:
In this case, the handler is removed regardless of the event type.
