Strip inline tracking handlers from elements

Cleans onclick/onmousedown attributes that call sendBeacon, gtag, fbq and similar trackers.

Code to copy

(function () {
  var hit = 0;
  document.querySelectorAll('a[onclick],button[onclick],[onmousedown]')
    .forEach(function (el) {
      var code = (el.getAttribute('onclick') || '') +
                 (el.getAttribute('onmousedown') || '');
      if (/sendBeacon|gtag\(|ga\(|_paq|dataLayer|fbq\(/.test(code)) {
        el.removeAttribute('onclick');
        el.removeAttribute('onmousedown');
        hit++;
      }
    });
  if (hit) console.log('[JustZix] Stripped tracking handlers from ' + hit + ' elements');
})();
