Answer 1

Вы можете сделать это:

JSON.parse('{"response":[{"job_id":"29","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"users"},{"job_id":"28","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"rajeev"},{"job_id":"27","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"pankaj"},{"job_id":"26","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"P","date":"2013-11-21 01:09:58","username":"users"},{"job_id":"24","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"D","date":"2013-11-21 01:09:58","username":"amit"},{"job_id":"25","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"P","date":"2013-11-21 01:09:58","username":"test"}]}') 

EDIT:

, чтобы получить все job_id сделать это:

var obj = JSON.parse('{"response":[{"job_id":"29","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"users"},{"job_id":"28","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"rajeev"},{"job_id":"27","message":"egfn","lattitude":"26.9514731","longitude":"89.4524783","job_status":"P","date":"2013-11-21 03:33:34","username":"pankaj"},{"job_id":"26","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"P","date":"2013-11-21 01:09:58","username":"users"},{"job_id":"24","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"D","date":"2013-11-21 01:09:58","username":"amit"},{"job_id":"25","message":"test job for you","lattitude":"25.4558641","longitude":"80.1325838","job_status":"P","date":"2013-11-21 01:09:58","username":"test"}]}') 

var job_id_array = new Array(); 

for(var i = 0;i< obj.response.length ; i++){ 
    job_id_array.push(obj.response[i].job_id); 
} 

Answer 2

Вы можете использовать JQuery.parseJSON()

Answer 3

Если строка JSON будет храниться в переменной json, вы можете сделать следующее (учитывая, что среда поддерживает ECMAScript5):

var o = JSON.parse(json); 
var result=[]; 
o.response.forEach(function(e){ 
    result.push(e.job_id); 
}); 
console.log(result); 

, который выводит содержимое массива result:

["29", "28", "27", "26", "24", "25"]
