Hi, I've config cross domain. here my code

<script src="~/Scripts/Global/xdUtils.min.js"></script>
   <script src="~/Scripts/Global/xdLocalStorage.min.js"></script>
   <script type="text/javascript">
       xdLocalStorage.init(
             {
                 iframeUrl: 'http://xxx.com/auth.html',
                 initCallback: function () {
                     console.log('Got iframe ready');
                 }
             }
     );

and after login success, I set data

  xdLocalStorage.setItem("tokenauth", response.access_token, function (data) {
                            if (data.success) {
                                alert("success");
                            } else {
                                alert("false");
                            }
                        });

When I run this code, it appear success

But when I read data

$(document).ready(function () {
            xdLocalStorage.getItem("tokenauth", function (data) {
                console.log("Token:" + data.value);                
            });          
        })

I get error

Cannot read property 'contentWindow' of undefined
