jQuery从不调用.done（）或.always（）进行ajax调用

Question

I'm having this simple get request:

   $.get('ri/i18n/locale')
      .done(function() {
        console.log(this);
      })
      .fail(function() {
        console.log(this);
      })
      .always(function(){
        console.log(this);
      });

Unfortunately none of the handlers are ever called.

I cann confirm that calling ri/i18n/locale in the browser returns a valid JSON string. I'm using jQuery 1.11.1 .

Any ideas what's wrong?

Your issue might be what version of jQuery you are using. Before jQuery 1.5, a jqXHR object was not returned with a $.get() , which is what allows you to use the promise behavior. The relevant jQuery documentation .

After all I just missed the asynchronous nature of the ajax call. I had a breakpoint on all console.log statements and the statement following the ajax call. Since the the statement after the ajax call was hit first I assumed none of the console.log statements gets called.

Since I need the result of the ajax call to go on, I have to move all my code into the done() function.
