Event handler function passed to jQuery during event binding. If false was passed during event binding, the handler refers to a single shared function that simply returns false.
Namespace(s), if any, provided when the event was attached, such as "myPlugin". When multiple namespaces are given, they are separated by periods and sorted in ascending alphabetical order. If no namespaces are provided, this property is an empty string.
The original type name regardless of whether it was mapped via bindType or delegateType. So when a "pushy" event is mapped to "click" its origType would be "pushy".

The type of event, such as "click". When special event mapping is used via bindType or delegateType, this will be the mapped type.
Many of the special event hook functions below are passed a
handleObjobject that provides more information about the event, how it was attached, and its current state. This object and its contents should be treated as read-only data, and only the properties below are documented for use by special event handlers.``
