Ajax json Parser Error

Question

I keep on getting a JSON parser error (firebug console say 'There are no child objects') for the following data:

(String) var data from each iteration

var data='['; 
data+=   '{ "title": "  Nac", "no1": "1212","no2": "12126"},';
data+=   '{ "title": "  Nac", "no1": "1212","no2": "12126"},';
data+=   '{ "title": "  Nac", "no1": "1212","no2": "12126"},';
data+= ']';

and javascript parsing json

var json = JSON.parse(data)

and jQuery AJAX request

        $.ajax({
        type: "POST",
        data: json,
        url : 'ticket.php',
        dataType: 'json',
        async: false,
        contentType : 'application/json; charset=utf-8',
        error: function(jqXHR, exception) 
        {
            if (jqXHR.status === 0) 
            {
                $('.item').html("err");
            } else if (jqXHR.status == 404) 
            {
                $('.item').html('err!');
            } else if (jqXHR.status == 500) 
            {
                alert("err!");
            } else if (exception === 'parsererror') 
            {
                $('.item').html('err parsererror');
            } else if (exception === 'timeout') 
            {
                $('.item').html('err!');
            } else if (exception === 'abort') 
            {
                $('.item').html('err!');
            } else 
            {
            $('.item').html('err!');
            }
        },
        success : function(data)
        {
            alert("okey");
        }           
    });

and ticket.php is completely empty because I don't no how receive json data from ajax in php

Any help would be highly appreciated. Thnks

No need to parse if you already set datatype=json.. Because it will already parse the JSON string as a javascript object — wirey00

tha parsing error is because of the ,(comma) after the last object of the string ie after the last '{ "title": " Nac", "no1": "1212","no2": "12126"}' you have to concatenate data with ] and not ,] — ismnoiet

JSON.parse gives you a JavaScript object, if you're sending json in a post then send json not an object. Also instead of building a json string, build an object and then stringify it

var data= [{
    "title": "  Nac",
    "no1": "1212",
    "no2": "12126"
},
{
    "title": "New",
    "no1": "12",
    "no2": "121"
},
{
    "title": "San",
    "no1": "1227",
    "no2": "1"
}];
var json = JSON.stringify(data);
        $.ajax({
        type: "POST",
        data: json,
        url : 'ticket.php',
        dataType: 'json',
        async: false,
        contentType : 'application/json; charset=utf-8',
        ...
