rewrite jQuery to vanilla JS

I want to get rid of jQuery in one of my old scripts. There are about 60 lines containing stuff like: $('.btnPrint').show(); $('#year').bind('cut keyup change paste', function () { ... } $("#nav a").each(function (index) { ... } $("#id").text(newValueString); $("#street").val(); $("#number").val(''); parseFloat(0 + $("#size").val().replace(",", "."), 10); $('#trRadioApartment').removeClass('disabled'); $('#inputRadioApartment').removeAttr("disabled"); $('#trRadioApartment').addClass('disabled'); $('#inputRadioApartment').attr("disabled", true); $('#inputRadioApartment').prop("checked", false); $("#baujahr").addClass("invalid_input"); $("#invalid").css("display", "inline"); $("#invalid").removeClass("invalid_input"); $("#invalid").css("display", "none"); This needs to be cleaned up, while being compatible to IE11+ Warning: I can only give a javascript file, which cannot be executed directly. I don't have permission to send you the complete application, since it contains non-free information.
