I have the following function

function show(x) {
document.querySelector(x).classList.toggle('hide');}

I am using it on html

<button onclick="show('p')">Button 1</button>
<p>This is p</p>
<button onclick="show('div')">Button 2</button>
<div>This is div</div>

Hide by default

window.onload = show('p');

Now I want to get all show() arguments so that window onload dinamicly change whatever the queryselector is.
