The forms will not submit in IE 11, they get hung up on "Please Wait"
var mktoForm = document.getElementById('mktoForm_1019'),
formSuccess = document.getElementById('form_success_1019');
formSuccess.innerHTML = "Thanks for your submission!";
mktoForm.setAttribute("style", "visibility: hidden; position: absolute;");
Has anyone every experienced this before? Or have some idea on how to fix it?
This isn't a Forms 2.0 problem.
You obviously can't call DOM methods that aren't supported cross-browser. (And it's not just IE 11, it's IE 8, 9, 10, and 11.)
var styleEl = mktoForm.querySelector('style');
Also I'm not sure why you're removing a <style> element. There are always better ways to use the CSSOM.
