jquery - 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

所以简短的回答是肯定的，您可以使用参数简单地调用 fetch 函数

{async:false}.

Answer 2

实际上主干获取方法在内部调用了ajax。因此，您可以将任何 ajax 选项传递给主干 fetch 方法。

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")            
          }
});
