You can use the Modulus Operator to determine if a number is even or odd. Basically, modulus is an operator that returns the remainder in division.
100 % 2 = 0
99 % 2 = 1
98 % 2 = 0
97 % 2 = 1
ect...
To go from 0 up to your random number, you can throw this method into a loop like so...
Code:
var randomnumber=Math.floor(Math.random()*10)
for(var i = 0; i <= randomnumber; i++)
{
if(i % 2)
{
alert( i + " is an odd number." );
} else {
// alert( i + " is an even number." );
}
}
Hope this helps.
