    A better question is why you need it to be synchronous. And the likely answer is that you're doing something the wrong way. – idbehold Aug 26 '13 at 18:27
  • It's an edge case scenario yes. – Petran Aug 26 '13 at 18:31

    Note that solution, suggested here, doesn't work anymore, since recent Mozilla Firefoxes don't allow async in jquery.ajax. – Boris Burkov Oct 29 '14 at 11:30

So the short answer is yes, you can simple call fetch function with param 

{async:false}.

Actually backbone fetch method internally calls ajax. So you can pass any ajax options to backbone fetch method.

collection.fetch({
  // ajax options
   async: false, // by default it is true
   success: function(collection, response, options){
             console.log("success")
          },
   error: function(collection, response, options){
             console.log("error")            
          }
});
