The function is invoked each time a card is selected

[Zoli]

A. "The function is invoked each time a card is selected"
B. "The function is invoked each time a card is clicked"
C. "The function is invoked each time a card is clicked on"

I don't know which one sounds more natural. Also, are they spelled correctly?

Side node: The text is tech related. I'm talking about playing cards. A function maps an input value of x into an output value of y similarly as in math. We usually say "invoke the function" but the phrase "call the function" is also used interchangeably.

Two things. One, I think they are all equally good. Two, the spelling is fine.

But they all lack final punctuation.

True.

If the selection is done on a computer with a mouse, I thought is usually "clicked on".

Note my corrections above.

You can say "as in" or "similarly to" but not the two together.

Yes, it is. If the idea is actually that you click on a card on the screen, then sentence B is not really right, in my judgement.

I don't see any problem with either "clicked" or "clicked on".
