You can use parseInt to convert your strings to integers in JavaScript:

var sum = parseInt(localStorage["pageno"]) + parseInt(i);
display(sum);

Need to parse the "1" in localStorage to an integer using the built in parseInt funtion:

var pagenumber = localStorage["pageno"];
var sum = Number.parseInt(pagenumber) + i;
display(sum);
