With the help of JQuery I've achieved it
var jsonArr = $("#jsonOutput").val();
if (jsonArr.toString() != "")
{ var stType = JSON.parse(jsonArr2);
var strType = $('#strType');
strType.append($('<option></option>').val('0').html('--Select--'));
for (i = 0; i < stType.response_list.length; i++) {
strType.append($('<option></option>').val(stType.response_list[i].code).html(stType.response_list[i].label));
}
}
