Question

var onemonth = 3;
var oneyear = 2005;
var twomonth = 10;
var twoyear = 2000;

How can i split this and compare?
In this example is:

var firstdate = onemonth + oneyear;
var seconddate = twomonth + twoyear;

if(firstdate < seconddate){
 alert('error');
}

How is the best method for compare two date if i have only month and year?

Answer 1

What about using the native Date object like this?

if (new Date(oneyear, onemonth) < new Date(twoyear, twomonth)){
  alert('error');
}else{
  alert('ok');
}

With your variables it will yield “ok”.
