JavaScript :: element.showAlert() not working

Question

I am trying to make a function where I can just put showAlert() after an element name and it will show an alert when clicked. I have defined my showAlert function in my JavaScript, but I always get an error.
I've tried:

        function showAlert() {
             return onclick = "alert('Hello World')"
        }

            document.getElementById('test').showAlert();

The code above should return: "document.getElementById('test').onclick = "alert('Hello World')",
However, I get an error saying: document.getElementById(...).showAlert is not a function

Thanks for any help.

What do you expect `showAlert()` to be? Also, show the code for the element for `id="test"` — Rojo, Jan 14 '21 at 19:16

You can use it like: `function showAlert() { alert('Hello World") }` and `

function showAlert() {
          alert('Hello World')
        }
        
 document.getElementById('test').addEventListener('click', showAlert)

<div id='test' >x</div>

I know that this is a way to do it but I want it to be a function that can just be placed after any element name, like: document.getElementById('test').showAlert() instead of adding the onclick event to the element. – user9719238713 Jan 14 '21 at 19:21
