org.json - Javascript handling .json file's lines -


how json file divided lines using java script.as done in python using readlines(). have uploaded .json file , need find keywords in , display lines in keywords found line number. example of json file given below:

{     "data": [],     "numfound": 0,     "context": {         "rows": "50",         "from": "2014-01-11t17:48:40.000z",         "until": "2014-01-11t17:48:40.000z",         "start": 0,         "query": "( json.system_version:3.4.42 json.id.discoveryserveruri:\"svcs.myharmony.com\" json.event_level:error json.crashcode:syncabort )",         "order": "desc"     }   }

i guess want load json file @ once. can this:

    function loadjson(callback) {                   var xobj = new xmlhttprequest();               xobj.overridemimetype("application/json");               //if want synchronous, replace false               xobj.open('get', 'json_file.json', true);               xobj.onreadystatechange = function () {               if (xobj.readystate == 4 && xobj.status == "200") {                 callback(xobj.responsetext);               }         };         xobj.send(null);        }

and then,

readjson(function(response) {     // "read" json     var data = json.parse(response);    //do whatever want  });

hope helps.
