Hello
If you have get it from controller by: "JsonConvert.SerializeObject" method,
you can try :

in JavaScript file:

JavaScript

function myFunction(response)
{
  var _Data = JSON.Parse(response);
  var _rid = _Data.rid;
}

so you can access "rid" variable.

Study this example in JavaScript (with comments), after all JSON follow JS syntax:

<script>

var JSON_String = '[{"rid":5,"latitude":6.95653333333333,"longitude":79.8554666666667,"trackerid":"01154524SKY7389","heading":39,"ReceivedUTC":"11/28/2016 12:42:16 AM"},{"rid":5,"latitude":6.95358333333333,"longitude":79.8539333333333,"trackerid":"01154524SKY7389","heading":244,"ReceivedUTC":"11/29/2016 12:42:17 AM"},{"rid":5,"latitude":6.95358333333333,"longitude":79.8539166666667,"trackerid":"01154524SKY7390","heading":48,"ReceivedUTC":"11/30/2016 12:42:16 AM"},{"rid":5,"latitude":6.95363333333333,"longitude":79.8541833333333,"trackerid":"01154524SKY7390","heading":7,"ReceivedUTC":"12/22/2016 12:42:09 AM"}]';

// parse it into an array of JavaScript objects
var obj = JSON.parse(JSON_String);

// loop thru the array
for (i = 0;i < obj.length; i++) { 

	// print out the attribute values of each object
	for(var attribute in obj[i]) {
    	document.write(attribute + ": " + obj[i][attribute] + "<br>");
	}
    
    document.write("+++++++++++++++++++++++++++++++<br>");

}
</script>

In this way, you can access any of the attributes. Just implement this same approach in JAVA or C# or whatever.
