jQuery ajax request not triggering JS response from rails controller?
This solution didn't work for me (rails 3.1 + coffeescript). After searching quite a lot, I found the good way to do it and I wanted to share:
Just add ".js" to the end of the url. So simple... ;-)
Just add dataType: 'script'
$.ajax({ url: $("form#new_picture").attr("action"), type: "POST", data: formdata, processData: false, contentType: false, dataType: 'script'});
You have to set the 'accept' header before sending the ajax request so that Rails knows how to respond.
$.ajax({ url: $("form#new_picture").attr("action"), type: "POST", data: formdata, processData: false, contentType: false, beforeSend: function(xhr, settings) { xhr.setRequestHeader('accept', '*/*;q=0.5, ' + settings.accepts.script); }});
