javascript - change json formated data by looping... the result is tripled -

i need change json formated data , want remove quotes in second column y on datalevel json array. first in code behind make function change datatable json format code

public string datatabletojsonwithstringbuilder(datatable table) {   var jsonstring = new stringbuilder();   if (table.rows.count > 0) {     jsonstring.append("[");     (int = 0; < table.rows.count; i++) {       jsonstring.append("{");       (int j = 0; j < table.columns.count; j++) {         if (j < table.columns.count - 1) {           jsonstring.append("\"" + table.columns[j].columnname.tostring() + "\":" + "\"" + table.rows[i][j].tostring() + "\",");         } else if (j == table.columns.count - 1) {           jsonstring.append("\"" + table.columns[j].columnname.tostring() + "\":" + "\"" + table.rows[i][j].tostring() + "\"");         }       }       if (i == table.rows.count - 1) {         jsonstring.append("}");       } else {         jsonstring.append("},");       }     }     jsonstring.append("]");   }   return jsonstring.tostring(); } 

i got data through jquery ajax , result this:

    {"d":"{ "datalevel":[{"name":"kebijakan/peraturan","y":"1"}, {"name":"lainnya","y":"3"},{"name":"utama","y":"3"}],  "datastatus" :[{"level":"kebijakan/peraturan","status":"belum dimulai","level1":"kebijakan/peraturan","y":"1","proyek":"pjm16.02.utama pke sop penjaminan"},{"level":"lainnya","status":"belum dimulai","level1":"lainnya","y":"3","proyek":"skl16.02 menyusun blueprint kegiatan sosial kemasyarakatan (csr) lps |skl16.03.utama seminar/sosialisasi/fgd dengan lembaga tertentu (termasuk seminar hut lps, seminar/sosialisasi/fgd dengan melibatkan anggota fkssk) |skl16.04 peningkatan hubungan kelembagaan, khususnya lps-bi-ojk"},{"level":"utama","status":"belum dimulai","level1":"utama","y":"1","proyek":"skl16.01.utama sosialisasi program penjaminan kepada masyarakat"},{"level":"utama","status":"active","level1":"utama","y":"2","proyek":"gai16.01.utama menyusun pedoman audit kinerja |pso16.01.utama penyusunan kajian organisasi lps (cary on 2015)"}]}"} 

then in aspx page make javascript function :

function getdata(datapie, tahun) {   var dataz = jquery.parsejson(datapie.d);   var dataarray = dataz['datalevel'];   //  var data = json.stringify(dataarray);   var countcolumn = countinobject(dataarray);   console.log(dataarray);   var jsonstring = "";   (var = 0; < dataarray.length; i++) {      jsonstring += "[";      (var j = 0; j < countcolumn; j++) {       jsonstring += "{";       if (j < countcolumn - 1) {         jsonstring += "name : '" + dataarray[j].name + "' , ";         jsonstring += "y :" + dataarray[j].y + " ";         jsonstring += "}, ";        } else if (j == countcolumn - 1) {         jsonstring += "name : '" + dataarray[j].name + "', ";         jsonstring += "y : " + dataarray[j].y + "} ";        }     }     if (i == dataarray.length - 1) {       jsonstring += " ";     } else {       jsonstring += "}, ";     }     jsonstring += "]";   };     return jsonstring; } 

this result got tripled...:

[{name : 'kebijakan/peraturan' , y :1 }, {name : 'lainnya' , y :3 }, {name : 'utama', y : 3} }, ][{name : 'kebijakan/peraturan' , y :1 }, {name : 'lainnya' , y :3 }, {name : 'utama', y : 3} }, ][{name : 'kebijakan/peraturan' , y :1 }, {name : 'lainnya' , y :3 }, {name : 'utama', y : 3}  ] 

the result want :

[{name : 'kebijakan/peraturan' , y :1 }, {name : 'lainnya' , y :3 }, {name : 'utama', y : 3}  ] 

anyone can me how fix this?

to convert strings numbers loop on data , change value string number

var dataz = jquery.parsejson(datapie.d); dataz['datalevel'].foreach(function(item){     item.y = +item.y || 0; });
