jquery - Ajax json Parser Error -

i keep on getting json parser error (firebug console 'there no child objects') following data:

(string) var data 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");         }                });

any highly appreciated. thnks

json.parse gives javascript object, if you're sending json in post send json not object. instead of building json string, build object , 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',         ...
