How do I pass parameters to addEventListeners?

Question

Please how do I pass parameters to an addEventListener and later pass a value the parameters when I click on it?
I've googled it and checked stack overflow, but I still don't know how to go about this.

Okay, thanks. Matiyas Sirak

Answer 2

No, I meant I want to pass parameters to the function itself. For example:

btn.addEventListener("click", myFunc(someVar))

And then change the value of someVar itself when I click on it. I know this doesn't work.

Try this code
const someInput = document.querySelector('button');

someInput.addEventListener('click', myFunc, false);

someInput.myParam = 'This is my parameter';

The argument on addeventlisterner is called here in the function👇

function myFunc(evt) {
window.alert(evt.currentTarget.myParam);
}
