Switch two blocks with a table in turn with the help of Js. How to do?

There are two div blocks. In each of the bottom of the table. I have a script:
function openbox(id) {
display = document.getElementById(id).style.display;
if(display=='none') {
} else {

<div class="switches">
 <a href="#" class="knopka1" onclick="openbox('Block1'); return false">Numerator</a>
 <a href="#" class="knopka1" onclick="openbox('Block2'); return false">Denominator</a>

How to make it so that pressing the link with another unit , the previous unit automatic hiding and another ?

A small trivial example. You can improve it
What to do now that the first open has always been? And when pressed the second , the first disappeared - Kelsi.Reichert commented on June 27th 19 at 15:18
