is there an alternative method to json.parser for ie

Question

I am using ie8 and so does everybody else. I need to make this script work for ie8. I cannot make json.parser work on IE. I tryied some of the recommendations that I saw here like json2.js modify html file etc. It does not seem to be working. Is there an alternative to this method? I really need this working and cannot figure out.

get_cpu.php outputs the data as this:

[1230000000,23]

This is my function. It works on chrome, firefox but not IE.

$(document).ready(function() {
 function request_cpu_Data() {

    $.ajax({

        url: 'get_cpu.php', 
        success: function(data) {
        alert(data.length);
                var myObj = JSON.parse(data); 
                var point = cpu_chart.series[0].points[0];
                var newVal=myObj[1];
        myDate=myObj[0];
        point.update(newVal);

        setTimeout(request_cpu_Data, 1000000); 
        },
        cache: false

    });
}

Can you provide the code which causes you an error? And are you sure that you are using `JSON.parse` written with those capital letters? — Niccolò Campolungo, Jun 13 '13 at 20:28

what version of jquery are you using? why aren't you returning a json mime type? — Daniel A. White, Jun 13 '13 at 20:31
@dandavis, I downlaoded json2.js from git and included in my file, I dont see any difference. Where did you get your version? — user1471980, Jun 13 '13 at 20:32
an error message that IE gives would be helpful. then, is your browser in IE7 compatibility mode? — akonsu, Jun 13 '13 at 20:32
@Daniel A. White, I am using jquery version 1.8.2, any ideas how I would address this issue. I am stuck. — user1471980, Jun 13 '13 at 20:33
@akonsu, IE says there is a sytax error on this line: var myObj = JSON.parse(data); — user1471980, Jun 13 '13 at 20:35
maybe it just cannot parse the data? that is why it gives syntax error? — akonsu, Jun 13 '13 at 20:39
@dandavis, when I open the html that include this javascript in chrome it works like a charm. On ie it does not work. — user1471980, Jun 13 '13 at 20:39
@akonsu, data is the values return from the get_cpu.php script [120000,4] — user1471980, Jun 13 '13 at 20:42
I am saying that it possibly throws an exception because it cannot parse the data that your server returns. return something else and see if it works. — akonsu, Jun 13 '13 at 20:44
@akonsu, is this line correct: var myObj = JSON.parse(data); IE saying syntax error — user1471980, Jun 13 '13 at 20:46
this line seems correct. IE might be saying 'syntax error' because it thinks that the json string has a syntax error. — akonsu, Jun 13 '13 at 20:46
comment out this line and insert `var myObj = JSON.parse('{}');` and see if it works — akonsu, Jun 13 '13 at 20:48

It possibly throws an exception because it cannot parse the data that your server returns.

I suspect IE8's implementation cannot parse JSON arrays.

You can try this, for example: https://github.com/douglascrockford/JSON-js/blob/master/json2.js

so, how I should the server return the values to ie? – user1471980 Jun 13 '13 at 20:54
try returning `{data: [120000,4]}`. if this does not work either then return the contents of your array as an object: `{elem0: 120000, elem1: 4}`. I do not know, play with it and see what works. – akonsu Jun 13 '13 at 20:55
you might be able to delete JSON; then load json2.js. If JSON already exists, json2.js does nothing. if you can kill the native JSON, then it should be using the json2.js's parser instead of the faulty native one. – dandavis Jun 13 '13 at 21:18
