Question

I am grabbing a string and using $.parseJSON(string) but keep getting the following error:

uncaught exception: Invalid JSON: {"0":{"chartHtml":"<p> Slide 1</p> ","presNote":"","chartOrderIndex":0},"1":{"chartHtml":"<p> Slide 2</p> ","presNote":"","chartOrderIndex":1},"2":{"chartOrderIndex":2},"3":{"chartHtml":"<p> e 3</p> ","presNote":"","chartOrderIndex":3},"4":{"chartHtml":"<p> Slide 4</p> ","presNote":"","chartOrderIndex":4},"5":{"chartHtml":"<p> Slide 5</p> ","presNote":"","chartOrderIndex":5},"6":{"chartOrderIndex":6}}

Firebug results during debug after running slideJson.d:

    >>> slideJson.d
"{"0":{"chartHtml":"<p> Slide 1</p> ","presNote":"","chartOrderIndex":0},"1":{"chartHtml":"<p> Slide 2</p> ","presNote":"","chartOrderIndex":1},"2":{"chartOrderIndex":2},"3":{"chartHtml":"<p> e 3</p> ","presNote":"","chartOrderIndex":3},"4":{"chartHtml":"<p> Slide 4</p> ","presNote":"","chartOrderIndex":4},"5":{"chartHtml":"<p> Slide 5</p> ","presNote":"","chartOrderIndex":5},"6":{"chartOrderIndex":6}}"

Here is some of the call to deserialize the json:

function (slideJson) {
var slideObj, jsonStr;
if (slideJson.d) {
    slideObj = $.parseJSON(slideJson.d);

Ajax call to get the Json with content type:

$.ajax({
    url: 'Someurl',
    type: "POST",
    data: "{}",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (data) { somenamespace.loadSlides(data); }
});

The JSON string in question ended up containing \n and \r in the chartHTML property, which by default are generated by the CKeditor .getData() method. Since i was pasting the errors from firebug they were not visible and the JSON appeared to be valid which lead to my confusion.

Thanks to those who answered.
