JQuery getJSON - ajax parseerror

Question

I\'ve tried to parse the following json response with both the JQuery getJSON and ajax:

[{\"iId\":\"1\",\"heading\":\"Management Services\",\"body\":\"


        

Answer 1

It is maybe because your output buffer is not empty, so AJAX receive bytes which don't belong to the JSON.

Try clean buffer with ob_clean() on server side just before output your json with echo or die(). And you don't need to specify contentType, I think for you default value will work correctly.

I had the same problem and it solve it.

Hope to help you.

Answer 2

in my case, the error was caused by a html tag in the json.

INCORRECT (parsererror)

{"msg": "Gracias,< br >Nos pondremos en contacto."}

CORRECT

{"msg": "Gracias, nos pondremos en contacto."}

BROWSER: IE7/IE8

Answer 3

The value you are trying to parse is wrapped in brackets [], which means it is an array. You are trying to eval an array. Try to eval the first element of the array, and it should work...

var json = eval("("+data[0]+");");

Also, I would recommend using the JSON.parse() provided here instead of calling eval() directly.

Answer 4

also try this

$.ajax({
    url: url,
    data:datas,
    success:function(datas, textStatus, jqXHR){
    var returnedData = jQuery.parseJSON(datas.substr(datas.indexOf('{')));
})};

in my case server responds with unknow character before '{'

Answer 5

Don't use an array box, and make sure you format your data properly:

{"account":{"iId":"1","heading":"Management Services","body":"<h1>Program Overview</h1><h1>January 29, 2009</h1>"}}

Answer 6

Disabling Firebug Lite fixed this problem for me.

Bug with combination of: jQuery 1.4, ajax/json, Firebug Lite and IE 8
