cannot access the row values of an object using javascript and ejs


I have an ejs file which looks like below



<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Google Maps Sensor Markers</title>
<script src="http://ift.tt/NF9SGx"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<p id="demo"></p>
<p id="pil"></p>
<p id="rowc"></p>
<script>
function addZero(i)
{ if (i < 10)
{ i = "0" + i;
}
return i;
}
var d = new Date(1382086394000);
//var x = document.getElementById("demo");
var h = addZero(d.getHours());
var m = addZero(d.getMinutes());
var s = addZero(d.getSeconds());
document.getElementById("demo").innerHTML= h + ":" + m + ":" + s;
var myVar = <%- JSON.stringify(jsresult) %>;
var count= <%- rowcount %>

document.getElementById("pil").innerHTML= myVar.rows[0].sensor;
document.getElementById("rowc").innerHTML= count;
</script>
</body>
</html>


which gives me the output like below:



01:53:14

6

7


I am trying to get the values of sensors from myVar by performing an iteration instead of accessing by using



myVar.row[0].sensor , myVar.rows[1].sensor and so on...


So I added something like this in between the above code



.
.
.

var myVar = <%- JSON.stringify(jsresult) %>;
var count= <%- rowcount %>

var arlene1= [];
for (var j=0; j<=count;j++)
{ arlene1[j] = myVar.rows[j].sensor ;
}

document.getElementById("pil").innerHTML= myVar.rows[0].sensor;
document.getElementById("rowc").innerHTML= count;

.
.
.


it now just throws a blank page without no output.


Can someone explain what is wrong over here??


I am basically trying to get the values of all 7 sensors into an array and then present them on the UI


The debugger console shows the error like below: enter image description here
