Find if variable is divisible by 2

Question

How do I figure out if a variable is divisible by 2? Furthermore I need do a function if it is and do a different function if it is not.

Answer 1

You can use the modulus operator like this, no need for jQuery. Just replace the alerts with your code.

var x = 2;
if (x % 2 == 0)
{
  alert('even');
}
else
{
  alert('odd')
}
