Uncaught SyntaxError: Unexpected token o

Question

I have a web app I am working on:

$("#post").click(function () {

    var u = $('#u').val();
    var j = $('#j').val();

    $.post("http://www.myweb.php", {
            u: u,
            j: j
        })
        .done(function (data) {


            var obj = jQuery.parseJSON(data);
            alert(obj.status );
            //alert("Data Loaded: " + data);
        });

});

When it tries to retrieve the JSON I get:

Uncaught SyntaxError: Unexpected token o

There is no syntax error in the code that you posted, it must be elsewhere, perhaps in the JSON data. [From the jQuery docs](https://api.jquery.com/jquery.parsejson/): **Passing in a malformed JSON string results in a JavaScript exception being thrown** — rink.attendant.6, Jul 03 '15 at 16:58
@rink.attendant.6 the syntax error is coming from the JSON parser. — Pointy, Jul 03 '15 at 17:01

You don't have to call .parseJSON(). Your response has already been parsed. You're getting that error because the object you pass to jQuery.parseJSON() is being converted to the string "[object Object]". The unexpected token is that "o" in "object".

so would I do data.status instead of obj.status if I take out the parse line? – Mike Jul 03 '15 at 17:02
@Mike yes, or just assign `data` to `obj`. – Pointy Jul 03 '15 at 17:02
