How to access attributes of class members in a single function?

Question

I want to create a function that when selected takes information from the button that was used, while using the same function as every other button (
Example: If Person 1 name= Harry and Person 2 name= George,
Then the function access the Person and number to get the name and will log either Harry or George based on whether button A or B is pressed without needing two seperate buttons)
I don't know if that makes sense, but please help as I would like to create dozens of these buttons using one function and do not want to have to make a dozen seperate buttons for the same function.

I have Person as the class, 1 and 2 as people in the class and name as an attribute of the class

Answer 1

From your code:
function show() {
document.getElementById("mess").innerHTML = {name} }

Should be:
function show(obj) {
document.getElementById("mess").innerHTML = obj.name }
