How do I use JSON.parse in Internet Explorer 9 with json2.js?

Question

I am using JSON.parse to turn a JSON string into a JSON object. It works in Google Chrome, Firefox, Opera, and Safari but not in IE9. Everytime I use JSON.parse Internet Explorer throws a "SCRIPT1014: Invalid character" error. I have included json2.js into the script since JSON.parse isn't supported in IE8 but to no avail does it still work. How can I make this work?

function run() {
        $("#testing").ajaxSubmit({
            success: function (data) {
                console.log(data);
                var parsedjson = JSON.parse(data);
                var truejson = parsedjson[0];
            }
        });
    }

Answer 1

The answer is to remove the "pre" tags surrounding the returned json string as Internet Explorer throws these tags on in order to preserve the structure of the text. The Form Plugin does work with Internet Explorer but only for same domain cases. CORS unfortunately is not supported by IE9. Solved the problem by doing this....

function imageUploader() {
        $("#testing").ajaxSubmit({
            success: function (data) {
                if (jQuery.browser.msie == true) {
                    var newdata = data.replace('<pre>', '');
                    var newdata2 = newdata.replace('</pre>', '');
                    var parsedjson = JSON.parse(newdata2);
                    var truejson = parsedjson[0];
                    var image = "<img src=" + truejson.thumbnail_url + " alt=" + truejson.name + "/>";
                    $("div#previewIe").html(image);
                } else {
                    var parsedjson = JSON.parse(data);
                    var truejson = parsedjson[0];
                    var image = "<img src=" + truejson.thumbnail_url + " alt=" + truejson.name + "/>";
                    $("div#previewIe").html(image);
                }
            }
        });
    }
