How to detect middle mouse button click?

Question

All of the questions I've seen on how to detect a middle mouse click in JavaScript are related to jQuery, but I'm wondering how I can detect middle mouse button clicks with regular JavaScript. I tried using onClick(), but it only appears to work for the left mouse button.

Is there a JavaScript function that can detect both left and middle mouse button clicks or, if not, that can detect middle mouse button clicks?

The reason I ask is that I want to make a function call when links are clicked, irregardless of whether the left or middle mouse button was used.

onclick is not tied to a mouse, but more on the target element itself.

Here's how to detect whether an element is middle clicked:

document.body.onclick = function (e) {   if (e && (e.which == 2 || e.button == 4 )) {     console.log('middleclicked')   } }
