Javascript Quit Executing in IE After Update

I recently updated to Nintex Forms 2010 (1.11.4.0) and my javascript has stopped working when using the IE 11 browser.  If I use Chrome it works fine.  It has been working for over a year and suddenly stopped with the update.  I was running a CAML query to populate form controls based on a lookup.  I have discovered that if I change the compatibility to Edge, then I am able to get the javascript to run in IE.  This makes it impossible to edit pages however.  Is there something I can change in the code to make it compatible with IE 11?

NWF$(document).ready(function () {
 //Get Form control values
 var employeeNumber = NWF$("#" + txtEmployeeNumber + ":input").val(); //NWF$(".employeeNumber :input").val();
 var selectedEmployee = NWF$("#" + ddlSelectedEmployee + ":input").val(); //NWF$(".selectedEmployee :input").val();
 alert("Employee Number: " + employeeNumber + "
Employee ID: " + selectedEmployee);
 //Determine if the employee number has been entered and the selected employee is blank
 //If the employee number is not blank and the selected employee is, then set the selected employee
 //Otherwise, do nothing. The form is new
 if (employeeNumber != null && selectedEmployee == 0) {
 selectEmployee();
 alert("Select Employee");
 } else {
 alert("Do not select Employee");
 }
});

function getEmployeeNumber() {
 //Get Form control values
 var employeeNumber = NWF$("#" + txtEmployeeNumber + ":input").val();
