Ajax fails but status code is still 200 "OK"

Question

I'm not sure why this is happening but i have a simple Ajax Code:

$.ajax({ url: "/javascript/testing.js"})
    .done(function(data){ console.log(data) })
    .fail(function(jqXHR, textStatus, errorThrown) {
         console.log(jqXHR);
    });

.fail() get's executed the status code is "OK". Also the data is present in responceText to the actual legit data. Why is this happening?

enter image description here

@karthikr legit data, `javascript` in my case. Error is `parseerror` — Kivylius, May 15 '13 at 16:47
@Jessica Can you examine the request in the browser to see if there is any additional information? — Vivin Paliath, May 15 '13 at 16:50
Set your dataType, it might be trying to parse it as "script" — nullability, May 15 '13 at 16:52
Returns javascript, @nullability I attemted to try "application/script" it don't work. — Kivylius, May 15 '13 at 16:53
Do you hava ajaxSetup globally somewhere? If so, make sure that you don't have some default set that would cause a conflict with this code, e.g. `method` set to `post`. — dgo, May 15 '13 at 16:54
@user1167442 the only thing i have is `$.ajaxSetup({cache: false});` — Kivylius, May 15 '13 at 16:55
@user1167442 `Load a JavaScript file from the server using a GET HTTP request, then execute it.` I don't want to execute it. — Kivylius, May 15 '13 at 17:00
Also, based on your example -> How can you tell `fail` is getting executed. They should return the same thing. — dgo, May 15 '13 at 17:01
What do you want to do with it? In other words, are you extending another object, saving it as a global function | global variable? — dgo, May 15 '13 at 17:01

If you want to parse the javascript file, then the dataType should be script:

$.ajax({ url: "/javascript/testing.js", dataType: "script" })
.done(function(data){ console.log(data) })
.fail(function(jqXHR, textStatus, errorThrown) {
     console.log(jqXHR);
});

If you are still getting a parserError then there is a problem with your testing.js file.

If you don't want to parse it and just retrieve it, then the dataType should be text:

$.ajax({ url: "/javascript/testing.js", dataType: "text" })

testing.js is just a regular javascript file. I replace the content to just `test` and it's still not working. – Kivylius May 15 '13 at 16:59
just `test` is not valid javascript. If you want to retrieve it without parsing it as javascript, set the dataType to `text`. I've updated my answer to reflect this. – nullability May 15 '13 at 17:08
