execute callback even if jquery statement fails

I have a jquery statement as follows:

$('.panel.col2, .panel.col3').fadeOut('fast', function(){
    //SOME CODE
});

The problem is that these elements do not always exist, and I need it to execute the callback regardless of the success of the statement the callback belongs to. Is there any workaround to this?

Try something like this:

function myCallback(){
   //SOME CODE
}

if($('.panel.col2, .panel.col3').length>0){

   $('.panel.col2, .panel.col3').fadeOut('fast', function(){
       myCallback();
   });
} else {
   myCallback();
}

It sounds like you want some code to run in the call back for fadeOut and outside if their are no elements to fade out. Here is an idea but I do not know the context of what you are trying to do.

$(document).ready (function () {
  var panelElement = $('.panel.col2, .panel.col3');
  var fadeOutCallBack = function(){
    //SOME CODE
  };
  panelElement.fadeOut('fast', fadeOutCallBack);
  if (panelElement.length == 0) {
    fadeOutCallBack();
  }
});
