Add two variables using jquery

Question

var a = 1;
var b = 2;
var c = a+b;

c will show as 12; but I need 3

How do I do it using jQuery?

Answer 1

This performs the addition of two variables supplied from input variables selected on the basis of ID.

var salary, tds, netSalary;
salary = parseInt($("#txtSalary").val());
$("#txtTds").on('mouseenter focus', function ()
{
    tds = parseInt($("#txtSalary").val() * (0.1));
    $("#txtTds").val(tds);
});
$("#txtNetSalary").on('mouseenter focus', function () {
    netSalary = parseInt($("#txtSalary").val() +("#txtTds").val());
    $("#txtNetSalary").val(netSalary);
});
