No 'Access-Control-Allow-Origin' header is present on the requested resource. 401 error
Question
I have been trying to implement spell check by using the bing spell check api. I am getting a 401 error. The error is
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 401.
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">
function hi(){
var params = {
// Request parameters
"mode": "{Spell}",
};
$.ajax({
url: "https://api.cognitive.microsoft.com/bing/v5.0/spellcheck/?" + $.param(params),
beforeSend: function(xhrObj){
// Request headers
xhrObj.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","{0c6cb56a997b41d4958ace895a677729}");
},
crossDomain: false,

type: "POST",
dataType: 'jsonp',
// Request body
data: {
dataSpell: $("#textContent").val()},
success : function(result){

}

{...} you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request.
Quoting answer from this thread , so check it out if you are still confused about why you are getting this error. You can learn how to bypass this using CORS here.
