IE11 does not support default parameters

function showOrHideField(curField="") {

would need to be

function showOrHideField(curField) {
   curField = curField || "";
   //or
   curField = curField!==undefined ? curField : "";

Or use a buildscript that runs a transpilier allows you to use those features and fixes the code for you. ;) https://babeljs.io/ – epascarello May 25 '17 at 23:11
