Preserved Topic: Does the ELSE always need to be specified

When writing an IF ELSE statement, do I always need to specify the ELSE, even if it's empty?

For instance, I have:

<script language=JavaScript type=text/JavaScript>
<!-- Enable Stealth Mode
var homepage=""
if (document.all)
{
document.write("<img src=/images/icons/homepage_icon.gif width=22 height=11 border=0 alt='homepage'> <a href=javascript:void(0); onClick=javascript:this.style.behavior='url(#default#homepage)';this.setHomePage(document.location);>Make this your homepage!<\/a>");
}
else
{
}
// Disable Stealth Mode -->
</script>


Since the ELSE part is empty, can I leave it off without some browsers complaining?

jope.

u know, that you don;t really need an else, if there is only one if-conditon, right?
( I mean, you are checking for a condition. (simplified):
If true, change it, if not, leave it.
That can be shortened to:
If true, change it.
That's why you don't even need an else. And the browser won't bother you.)
(well, shouldn;t... let's see what the others say )

only change remains

ELSE part (if empty) is not needed...

Thanks, guys. One of these days, I might actually understand this stuff.....

Indenting your code may help :P

Yeah, think of "else" as something that you're allowed to *add* to an if statement, not something that you're allowed to leave out. It's an accessory, sorta.
