"id": "engcall1",
"action": {
"action": "call",

if id is engcall1 then i should display only
"action": "call",
"dialcode": "9880214866"
function getvalue(id)
{
var data1;
var data2;
var data3;
var items = jsontxt.items;
for (var i = 0; i < items.length; i++) {
if (items[i].id == id ){ //search for id in items.
var data= items[i].action;
if(items[i].action.action == "call")
{
data1= items[i].action.action;
data2= items[i].action.dialcode;
}
if(items[i].action.action == "sms")
{
data1= items[i].action.action;
data2= items[i].action.dialcode;
data3= items[i].action.msgbody;
}
if(items[i].action.action == "ussd")
{
data1= items[i].action.action;
data2= items[i].action.dialcode;
}
if(items[i].action.action == "url")
{
data1= items[i].action.action;
data2= items[i].action.url;
}
}
}
test(data1,data2,data3)
}
function test(data1,data2,data3){
alert(data1);
