ebArgsStyle.trigger('a' , [ 1 , 2 ]);
ebArgsStyle.remove('a' , function(a , b ){ console.log(a + ' ' + b ); } , function(a , b ){ console.log( b + ' ' + a ); });ebArrayStyle.add('a' ,[ function(a , b ){ console.log(a + ' ' + b ); } , function(a , b ){ console.log( b + ' ' + a ); } ] );
ebArrayStyle.trigger('a' , [ 1 , 2 ]);
ebArrayStyle.remove('a' , [ function(a , b ){ console.log(a + ' ' + b ); } , function(a , b ){ console.log( b + ' ' + a ); }]);dead-simple-event-bus optimizes the event bus by not allowing more than one copy of function to be added.
ebSingle.add('a' , function(a , b ){ console.log(a + ' ' + b ); }); // assigns event
ebSingle.add('a' , function(a , b ){ console.log(a + ' ' + b ); }); // avoids assigning and prints messageBy default , duplicate functions print a message to console and doesn't get addedup again on the event bus. If you want to handle this manually , you could dig a bit into the source and insert a callback.
