Ajax call working on Google Chrome but not on IE 11
As I can see your Button type="submit". If it is inside the form tag then call the ajax request in action of the file. As I can see from above comments this might be the issue. As you are submitting something this changes to a POST request and not GET request so its giving the error method not allowed. And looking at the solution just change the Button type='button' or call the ajax on the action of form tag. It should work.
