Code to copy
// Strip tracking parameters from outbound product links
(function () {
var JUNK = /^(utm_|ref$|ref_src|source$)/i;
function clean() {
document.querySelectorAll('a[href*="?"], a[href*="&"]').forEach(function (a) {
if (a.dataset.jzClean) { return; }
var href = a.getAttribute('href') || '';
if (!/^https?:/i.test(href)) { a.dataset.jzClean = '1'; return; }
try {
var u = new URL(href);
var changed = false;
Array.from(u.searchParams.keys()).forEach(function (k) {
if (JUNK.test(k)) { u.searchParams.delete(k); changed = true; }
});
if (changed) { a.setAttribute('href', u.toString()); }
a.dataset.jzClean = '1';
} catch (e) { a.dataset.jzClean = '1'; }
});
}
clean();
var obs = new MutationObserver(function () {
clearTimeout(window.__jzPrhClean);
window.__jzPrhClean = setTimeout(clean, 500);
});
obs.observe(document.body, { childList: true, subtree: true });
