For example I have a function:

var f1 = function(arg) {

    var a;

    $.ajax({

        ...

        success: function(data) {

            a = f2(data);

            //return a;

        }

    });

    //return a;

}



var f3 = function() {

    a = f1(arg);

}

How can I return a after AJAX get data in f1?

You can't return the result of your ajax request since the request is asynchronous (and synchronous ajax requests are a terrible idea).

Your best bet will be to pass your own callback into f1

var f1 = function(arg, callback) {

    $.ajax({

        success: function(data) {

            callback(data);

        }

    });

}

Then you'd call f1 like this:

f1(arg, function(data) { 

           var a = f2(data);

           alert(a);

        }

 );
