is there a javascript (or jquery) short cut for "function(){return false;}"?

It seems like I type "function(){return false;}" some what too frequently too prevent actions from happening... is there a short cut?

From stackoverflow

• You can cancel an event default action by using the preventDefault method:

  $("form").bind("submit", function(event){ 
    event.preventDefault(); 
  });
  

• Do you really think that's too much typing?

  Why not have a global variable named f set to false, and use function() {return f;}

  Ates Goral : function f() { return false; }

  Chris Noe : Seems like a false economy :-7

  zildjohn01 : @Ates -- got me there :)

• You could declare a named function like this:

  function always_false() { return false; }
  

  then use "always_false" wherever you would have created the anonymous function previously.

  Unkwntech : I'm thinking call it something shorter like ff() (bad name I know) and so that it's even shorter but this seems like the right idea.

  Luca Matteis : What, this will not work, -1, please explain.

  Luca Matteis : Oh, "always_false" would be the actual listener?

  Luca Matteis : then I would expand that, since he's using jquery to: function always_false(e){e.preventDefault();}

• I often have a "no op" function defined at the top of my common js file:

  function nop() { return false }
  

  I use it whenever I need a "do nothing" or a "cancel event" handler (eg div.oncontextmenu = nop). In IE this has the added benefit that memory does not leak when creating similar [anonymous] functions on the fly and assigning them to event handlers. At least that's what IE Drip tells me.

  Luca Matteis : return false; doesn't "cancel event"s.

  Crescent Fresh : @Luca: try it some time.

• Just set the event handler to null. This is cleaner than assigning to a "return false" function IMO because it removes the event handler altogether.

  myButton.onclick = null;
