Random number loop program - javascript

Question

I would like my program to return 10 random numbers but it isn't working it doesn't load the random numbers, I have linked the program to index.html so that's not the problem here, this is what I have tried:

function randomNumber(upper) {
    return Math.floor(Math.random() * upper) + 1;
}
var counter = 0;
while (counter < 10) {
    var randNum = randomNumber(6);
    document.write(randNum + ' ');
    counter += 1;
}

So what does "it isn't working" mean? Are you waiting for onload? — tckmn

maybe you are printing the results in the header of the page ... — Nina Scholz

If it works in fiddle but not elsewhere it's most probably a problem with onload here as Doorknob already suggested.

function randomNumber(upper) {
    return Math.floor( Math.random() * upper ) + 1;
}
window.onload = function () {
  var counter = 0;
  while (counter < 10) {
    var randNum = randomNumber(6);
    document.write(randNum + ' ');
    counter += 1;
  }
};

The bracketing with window.onload causes the code to wait until the whole page is loaded.
