handling csv response in backbonejs

Question

I am posting some data to server through Backbone.js and server sends a csv file as response. As Backbone.js handles only json format can some body tell me how to handle this case, so that i would be able to download the csv file gracefully.

  object = {};
  object.c1 = formObj.c1
  hash = {
    success: function(model, response, options) {

    },
    error: function(model, response, options) {
      return console.log(response);
    }
  };
  model = new P.models.mine(object);
  model.doSomething(object, hash);

It always comes to error part.

The ideal way to handle this would be to change your back end code to return JSON, or create another route that returns JSON. Since you are asking this question I'm assuming that isn't an option for you.

Basically you are going to have to parse the CSV on the client side:

If you are asking to download a csv file, then just pointing the browser at the location should prompt the user for download. You cannot prompt a file download through ajax(for good reason), but there are ways to tiptoe around this limitation:
