interface nsIDOMNSEventTarget : nsISupports
Attributes
The default script type (language) for events firing on this target. Must be one of the nsIProgrammingLanguage enums, but must not be nsIProgrammingLanguage::UNKNOWN. Most implementations will provide a default type of nsIProgrammingLanguage::JAVASCRIPT. All targets must support fetching the script language, but not all script targets must support changing it - ie, some targets may only support event handlers written in their default language.

Methods
This method is the same as the addEventListener() method defined
in nsIDOMEventTarget, but it takes one additional argument which
lets callers control whether or not they want to receive
untrusted events (synthetic events generated by untrusted code)
@param type See the type argument to the same method in
nsIDOMEventTarget.
@param listener See the listener argument to the same method in
nsIDOMEventTarget.
@param useCapture See the listener argument to the same method in
nsIDOMEventTarget.
@param wantsUntrusted If false, the listener will not receive any
untrusted events (see above), if true, the
listener will receive events whether or not
they're trusted
