How to get response code in backbone js?

Question

How can I get Response code in backbone js when i fetch the result using fetch() method of collection? I know it executes error callback function when the response code is like 4xx and success callback method when the Response code is like 2xx.

var x = user.fetch({
    error:   function(model, xhr, options){
       alert('Error on fetch')
       console.log(xhr.responseText);
    },
    success: function(model, response, options) {
        alert(user.toJSON());
    }

Here I want to get Response code, No matter whether It is an error callback or success callback.

Thanks in Advance.

If you want response code get it like this: -In case of success,

console.log("Response code in case of success:",options.xhr.status);

-In case of error,

console.log("Response code in case of  failure",xhr.status);
