How can I make a sync call with backbone fetch

Question

I need to call a fetch with a synchronous call, I know with jquery ajax I can use {async: false} can I pass this option to fetch function ?

Answer 1

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

{async:false}.

Answer 2

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")            
          }
});
