How to set value of a variable on button click

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?

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;

no window load is correct but you should not have function inside it.
