JSON URL not working with Parameters

Question

I have written the following code to read a JSON document from an external URL. This worked fine when the URL was the following:

 http://localhost/EWSimpleWebAPI/odata/Users?

But NOT when I modified the URL as the following:

http://localhost/EWSimpleWebAPI/odata/Users?$filter=USER_NAME%20eq%20%27corpnet\anuwlk%27&$select=PROFILE

Javascript

var xmlhttp = new XMLHttpRequest();

var url = "http://localhost/EWSimpleWebAPI/odata/Users?$filter=USER_NAME%20eq%20%27corpnet\anuwlk%27&$select=PROFILE";

xmlhttp.open("GET", url, true);

xmlhttp.onreadystatechange=function() {
  if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
    myFunction(xmlhttp.responseText);
    errorAlert("Status OKAY");
  } else{
    errorAlert("Status Not OKAY")
  }
}

xmlhttp.send();

I'm retrieving the JSON Document thru a Web API using OData. OData accepts parameters in the URL and it worked fine in POSTMAN. I'm developing a Google Chrome extension and I'm not sure if it supports this URL with Parameters.

Your url has an unescaped control character \a, should be \\a. I've voted to close the question due to the problem being a typo. — woxxom

It would be best to use some function ( encodeURIComponent(str) and encodeURI(str) come to mind) to encode the parameters correctly.

As wOxxOm commented, your issue seems that one of the parameter has an unescaped character \.
