stripmkttok.js
Has anyone run into this and perhaps have any insight as to what the context is on why Marketo is now removing mkt_tok values after the URL resolves? So far, I've found this to be happening on all Marketo hosted landing pages that are linked from an email with mkt_tok and the view as webpage link.
Looks to be happening in multiple sandboxes and instances so it seems to be a global thing perhaps?
Started seeing this exactly on the release date.
Anything would help at this moment, documentation, release notes, etc.
Full script:
// LM-100892: Once page process mkt_tok, remove parameter from URL
(function() {
var afterLoad = function (fn) {
if (window.attachEvent) {
window.attachEvent('onload', fn);
} else {
window.addEventListener('load', fn);
}
},
// get parameter from URL
getURLParameter = function (name) {
var returnVal = decodeURIComponent((new RegExp(name + '=' + '(.+?)(&|$)').exec(location.search) || ['', null])[1]);
return returnVal;
}
afterLoad(function () {
// Cache mkt_tok value into global variable, before stripping it from URL
window.__mktTokVal = window.__mktTokVal || getURLParameter('mkt_tok');
window.history && history.replaceState('', null, location.pathname + location.search.replace(/(\?)?mkt_tok=(.*?)(&|$)/gi, '$1$3') + location.hash);
});
})();
