[removed] removing an anonymous event listener [duplicate]

Answer 1

You need to keep a reference to the function:

var foo = function(event) { _SU3.getChildren(_show, uri, element); };

_SU3.addEventListener(_show, "click",  foo);

...

_SU3.getChildren = function(_show, url, element) {

... blah... 

_SU3.removeEventListener(_show, 'click', foo);

};

Make sure that the variable foo is in the scope of where you remove the event listener.
