Question

I am experiencing a strange problem while trying to parse JSON strings in jQuery AJAX response. Here is my code:

$.ajax({
    type: "POST",
    url: "Save",
    data: {
        expiry: expiry,
        settings: settings
    }
}).done(function (msg) {
    alert(msg);
    var obj = jQuery.parseJSON(msg);
    if (obj.status == "done") {
        window.location = obj.redirect;
    }
});

On IE, Chrome, and Safari, I am getting JSON string in alert, but on Firefox, I am getting

[obj XMLDocument]

in the alert.

Here is FF console:

obj is null, but I can see the response JSON string in the console under text attribute

responses=Object { xml=document, text="{"status":"done","redir...ippetImage\/s\/6abb68"}

Any reason for this behavior?

Problem was on servlet side. I had to set contentType to make it work.

response.setContentType("text/JSON");
