getting NaN, not increment the attribute value

Question

alert($(this).attr("data-itemindex")); is giving me '999999999999999003'
and alert(dataValue); is giving 'NaN'

but why?

I am expecting '999999999999999004'

alert($(this).attr("data-itemindex"));
var dataValue = Number($(this).attr("data-itemindex")) + 1;
alert(dataValue);

@techouse parsiInt and parseFloat not helping me, still i am getting `NaN` — Shiva Roy, Apr 15 '14 at 12:14

Your number is too big. The maximum possible number is:

9 007 199 254 740 992

Have a look at this question.

if you would like to try this:

example of use:

var strint = require("./strint");
strint.add("9007199254740992", "1")
//'9007199254740993'

this is working

var dataValue="'999999999999"+("000"+(parseInt($(this).attr("data-itemindex").slice( -3 ),10) + 1).toString()).slice(-3)+"'";
