Making two scripts co-exist on one page.

Hello everyone! Merry Christmas to you!

I have these two scripts that both work separately but not together. Obviously, they are virtually identical except the X's to make them different. I thought that would be enough, but clearly it wasn't.

How can I have these two co-exist on the same page? I might even add a third or fourth...just to let you know.

Thank you in advance!

And if it's not possible to get these to work simultaneously, is there anyway to combine them? I mean, can more than just one character be randomly dropped from the top of the screen? Thank you!

The problem I see are these lines:

Code:

---

window.onload=initsnow
window.onload=initsnowX

---

window.onload can only hold one value. Put those calls in a new function to make it work:

Code:

---

window.onload=function() {
    initsnow();
    initsnowX();
}

---

a problem that I see is that you are testing for IE 5 and Netscape 6, which tells me that this is very, very ancient code. Maybe maybe somebody's grandmother out there still has IE 6 but 5? That got superceded in 2001 :eek:

I'd have a look at your code in a couple of modern browsers before going much further - my versions of Firefox and Chrome don't like it at all. Even IE 8 just makes the snowflakes buzz from side to side on the first line of the screen.

This "snowstorm" code seems to be popular for some reason:
