json xhr response opens a download file popup window

Question

For one of our ajax request (with a .json response) some of our clients have complained that they are seeing a \"File Download\" prompt asking the user to download the .json res

Answer 1

Not sure if you found a solution, but I had a similar problem where IE tried to download any JS responses. To fix it, I had to ensure that format.html appears above format.js in the response block:

def index

  # ...

  respond_to do |format|
    # html must be above js, otherwise IE will try to download the JS
    format.html
    format.js
  end
end

Hope this helps.
