[ { callid: 4, name: {"vahid", "reza"} },  { callid: 5, name: {"vahid", null} }  ]

can 1 help,
tried every things , ifs i'm doing wrong in somewhere in forward

try using _, http://jsfiddle.net/swdsm/3/

this convert data array arr[callid] = [name, ...]

var arr = _.inject(data, function (memo, row) {     memo[row.callid] || (memo[row.callid] = []);     if (row.name != null && memo[row.callid].indexof(row.name) == -1) {         memo[row.callid].push(row.name);     }     return memo; }, []);

and convert u expect

var result = []; (var key in arr) {     result.push({callid: key, name: arr[key]}); }
