Javascript not working in IE but work works in Chrome

Question

I had a long search and until I found a working script to use the logged in user id. Finally I have found the following Javascript code, put it in XSL to be used in an XMl viewer web part:

<script language="javascript" defer="true">
      <xsl:comment>
        <![CDATA[

ExecuteOrDelayUntilScriptLoaded(init,'sp.js');
var currentUser;
function init(){
    this.clientContext = new SP.ClientContext.get_current();
    this.oWeb = clientContext.get_web();
    currentUser = this.oWeb.get_currentUser();
    this.clientContext.load(currentUser);
    this.clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceeded), Function.createDelegate(this,this.onQueryFailed));
}

function onQuerySucceeded() {
}

function onQueryFailed(sender, args) {
    alert('Request failed. \nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
}

        ]]>
      </xsl:comment>
    </script>

I call the function like this:

<A class="bluelink" href = "javascript:void(0)" onclick="javascript:window.location='{$mailtolink}' + '%0D%0Auserid: ' + currentUser.get_loginName() + '%0D%0Aurl: ' +  window.location; return false;">Request additional rights</A>

The mailtolink variable represents a valid mailto: link. The problem is, that in IE11 (also in IE8 compatibility mode), the mail body ends only with

userid: i:0

However in Chrome, I get all the details I need:

userid: i:0#.w|tdomain\testuser
url: https://myserver/testsite/default.aspx

I made the mail body shorter, to make sure it is not the lenght, but I got the same results. Can someone give me a hint how to make the script work in IE?

If you are getting alert of user name as per your comment then you should follow below approach:

DOM Element:

<a id="myLink" class="bluelink" href="javascript:void(0)">Request additional rights</a>

Script:

<script language="javascript" defer="true">
  <xsl:comment>
    <![CDATA[
        ExecuteOrDelayUntilScriptLoaded(init,'sp.js');
        var currentUser;
        function init(){
            this.clientContext = new SP.ClientContext.get_current();
            this.oWeb = clientContext.get_web();
            currentUser = this.oWeb.get_currentUser();
            this.clientContext.load(currentUser);
            this.clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceeded), Function.createDelegate(this,this.onQueryFailed));
        }

        function onQuerySucceeded() {
            $('#myLink').attr("onclick", "javascript:window.location='<..your url string..>"+ currentUser.get_loginName() + "return false;");
        }

        function onQueryFailed(sender, args) {
            alert('Request failed. \nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
        }

    ]]>
  </xsl:comment>
</script>

Your code might be failing due to invalid flow of execution for IE.

IE has different mechanism than other browser.

I finally found the answer: It looks like that IE doesn't like the #, that was present in the userid i:0#.w|tdomain\testuser, in the mailto URL. Doesn't matter where I put the #, the rest of the url is ignored by IE.

If you want to get just the user ID of currently logged in user, you can use the following code.:

 var userID = _spPageContextInfo.userId;
