window.opener does not work in https, but ok in http

Hello, I have a strange situation related to javascript window.opener.
I have 2 websites hosted in the same platform, UAT&PRD.
The only difference, beside the domain, is that UAT is on http, and PRD on https.

The below script works fine in UAT, but in PRD (https) I have the following error:

Error:

TypeError: window.opener.document.getElementById(...) is null

Open in new window

System.Text.StringBuilder sbScript = new System.Text.StringBuilder();
                    sbScript.Append(@"setTimeout(function(){closePopup()},2000);window.opener.document.getElementById('" + anchorId + "').click();");
                    if (!ClientScript.IsStartupScriptRegistered("scriptTest"))
                        ClientScript.RegisterStartupScript(this.GetType(), "scriptTest", sbScript.ToString(), true);

Open in new window

javascript

function closePopup(){
    var opener = null;
    if (window.dialogArguments) // Internet Explorer supports window.dialogArguments
    { 
        opener = window.dialogArguments;
    } 
    else // Firefox, Safari, Google Chrome and Opera supports window.opener
    {        
        if (window.opener) 
        {
            opener = window.opener;
        }
    }       
    // write you code and refer "opener"
    window.close();
 };

Open in new window

To be mentioned that both PRD pages (opener and popup) are under https://
Thanks

It is complaining the element is null, not that the opener does not exist.

Perhaps it is a security issue. Can you try lowering the security while testing?

Unfortunately, same result, ok in UAT, not ok in PRD, same javascript error, which is telling me that some sort of security is preventing this script to work.
I forgot to include in initial code the anchorId tag, in opener page:

<a id="anchorId" runat="server" onclick="return true" onserverclick="postback"></a>

Open in new window

Below the script generated by Firebug, that is causing the error:

TypeError: window.opener.document.getElementById(...) is null

Open in new window

<script type="text/javascript">
//<![CDATA[
(function() {var fn = function() {$get("ToolkitScriptManager1_HiddenField").value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();setTimeout(function(){window.opener.document.getElementById(' MainContentPlaceHolder_anchorId').click();closePopup()},2000);(function() {var fn = function() {Sys.Extended.UI.ModalPopupBehavior.invokeViaServer('mpeTrainingFinished', true); Sys.Application.remove_load(fn);};Sys.Application.add_load(fn);})();Sys.Application.initialize();

I have finally solved it, the anchorId should have been ctl00_MainContentPlaceHolder_anchorId and not MainContentPlaceHolder_anchorId, as initially set.
however, I will set the second answer as solution, as it is correcting my code
Thanks

The solution is posted in the last comment, however this post is showing the correct way to handle my script
