Do pupils only dilate when looking at something desirable?

No, but they certainly do dilate in cases of observing an object of desire.

Eyes also naturally dilate in low light conditions to allow more light to enter the eye.

They can be chemically dilated so a doctor can see into the eye easier than if they were not dilated.

There may be more situations that I'm not aware of in which eyes will dilate.

No.
When it is dark out to let in more light, and on any drug that is a stimulant.
Eyes wide open.
It really looks weird.

Would being on an elevator cause pupils to dilate? There's some lights it's a hotel elevator.

Sounds like those memes.

So they only expand when looking at someone u love. I was on the elevator with the guy I work with for the second time and as I'm talking and looking at him his pupils were dilated.

No, pupils also do this when adjusting to lightlevels or when high.

[RyanK9b]

No, they dilate also in the dark.
Cocain, Pain, migraine attack, brain dmg do also change pupils

What about feeling happy or excited about something.

[RyanK9b]

Yes that too. But its more generally described as mental arousal. So fight, flee and everything that makes you active has an impact on that.
In your case, very high arousal with heart rate increase should also react in that way.

Also would a person pupils become in large in a elevator the elevator wasn't dark.

[RyanK9b]

If said person is scared of the elevator yes. So high tension

[SnowedIn]

Nope. Function of light too.

Pupils dilate in the dark too.
