Hi everybody,
I am trying to listen to an event just once, but I don't get it to work.
Here is my code:
/**
* listens for an event just once
* @param string event name
* @param function handler function
**/
zophe.event.once = function ( name, callbackFunc )
{
var o = { callback: function(e) {
callbackFunc(e);
zophe.event._remove ( this );
} };
window.application.addEventListener ( name, o.callback );
};
zophe.event._remove = function ( o )
{
window.application.removeEventListener ( name, o.callback );
delete ( o );
}
Now I do:
zophe.event.once( "requests-completed", function(){
alert ( "all requests completed" );
});
It will continue to call my alert function if a "request-completed"
event is dispatched. Any ideas?
Christian
