I get positive output whether tag is empty or not. Maybe you need to put your JS code into a window.onload event trigger.

Answer 3

Priyanshu Gupta(प्रियांशु गुप्ता) Seriously? I get the output "There is a p element" on this code.

se this if you have empty tag then it show not p element , and when i add something in p tag , it again show not p element

Answer 6

you can check number of p elements in document using this code in script

var p = document.querySelectorAll("p") ;
console.log(p.length);

Answer 7

ok then replace p in with audio

var p = document.querySelectorAll("audio") ;
console.log(p.length);
if no audio tag console value = 0

Answer 8

Russ not working your code , empty tag is considered as your else case
