Why doesn’t my code work

Question

I have a document.getElementById but it won’t show please help

Answer 1

use "window.alert" or "console.log" instead of "document.write"

and also replace line 16 ( in js code ) by that:
document.getElementById("FA2").style.display = "block";

check this for more about diff between display and visibility

Answer 2

So you have an understanding why its not working as intended is because you are using document.write() in the hit() function.

document.write() clears all HTML from the document. This is why your call to display the FA2 isn't working, because the div has been cleared from the document.
