End of input when no JSON is returned with 200 OK from server.

[constantm]

Awesome addon! However, when used with Rails and response is set with the following:

respond_to do |format|
  format.json { head :ok }
end

You get an error:

SyntaxError: Unexpected end of input
    at Object.parse (native)
    at jQuery.parseJSON (http://localhost:4200/assets/vendor.js:7736:14)
    at ajaxConvert (http://localhost:4200/assets/vendor.js:8013:19)
    at done (http://localhost:4200/assets/vendor.js:8429:15)
    at XMLHttpRequest.<anonymous> (http://localhost:4200/assets/vendor.js:8819:9)

However, when you add some actual JSON content to the response, it seems to work fine.

I ran into this issue yesterday. The reason you are seeing an error is because ember-ajax expects a JSON response by default (see this line), and as a result is attempting to parse the response as JSON.

If you're not returning a JSON response, you should update the dataType attribute to something more appropriate. For possible values, see jQuery's $.ajax() docs for dataType.

e.g.

this.get("ajax").request("/some/request/url/", {
  dataType: "text"
});

I think this lib should not force the dataType to be JSON, the default auto detection of jQuery is just fine.

Considering that @mike183 posted the solution to this issue, I'm going to close it out.
