How to set value of a variable on button click

Question

like in a calculator when u tap 1 it shows 1
but the only exception is that I need only 4 digits and I need to assign each digit to each variable,
like if first digit is 1(or any other no.) then its variable should be num1 and for second digit num2 , third digit num3 and lastly fourth digit num4
can anybody help?

Answer 1

what about this.

<button onclick="assign(1);" >num1</button>

<button onclick="assign(2);" >num2</button>

in JavaScript

var x=0;
var arrs = [];
function assign(val){
arrs[x] = val;
x++;
}

now each array is new val;
