and i'm trying parse data using jquery i'm using jquery post method send data , response , , i'm trying part of data useful me : cm_1_1 : 1 not 1 of cm_ variables values.

when show response in html format it's : enter image description here

this jquery code :

 $(function(){             var vop_id = localstorage.getitem('op_id');             $.post("requests/ops.php", //required url of page on server                 {   // data sending request server                     load_op_cm : true,                     op_id : vop_id                 },                 function(response){  // required callback function                     var result = response;                     $.each(result, function (i,elem) {                         $("#response").text(elem);                     });                  });

any suggestion how data ?

firstly need parse json string var result = json.parse(response);. when iterate through need filter results include keys contain 'cm_'

var filter = "cm_"; $.each(result, function (i,elem) {     if(i.indexof(filter) !== -1) {         console.log(i, elem);         // or whatever need do…     } });
