JavaScript/HTML Problem

Question

A while ago I asked a question that gave me a piece of code I'm using for something. Here's something that involves that:

function jg() {
while (y = document.querySelector('html > *')) {
y.parentElement.removeChild(y);
break;
}
}
function nav(x) {
jg();
document.write(x);
}

I used the function nav() as the onclick for some spans in a paragraph. I can onty click the "link" three times. Why is that?

You did not show how your HTML looks like - could you please post the code on playground and link it here?
