Question

I am trying to open popup window or new tab but without losing focus of current tab but it not working to any browser, below is code which i tried

1st option :

var win=window.open('https://www.sites.com',null,"height=1,width=1,status=no,toolbar=no,scrollbars=no,menubar=no,location=no");
    win.blur();
    window.focus();

 var win=window.open('https://www.sites.com',null,"height=1,width=1,status=no,toolbar=no,scrollbars=no,menubar=no,location=no");
    win.opener.focus();
    window.opener.focus(); 

3rd option:

var win=window.open('https://www.sites.com',null,"height=1,width=1,status=no,toolbar=no,scrollbars=no,menubar=no,location=no");
window.onblur = () => window.focus();

Also tried jsonp call, but due to azure AD B2C login it does not get logout :

$.ajax({
            url: 'https://www.sites.com',
            type: "GET",
            data: null,
            crossDomain: true,
            async: false,
            dataType: "jsonp",
            success: function () {
            },
            fail: function (respone) {
            }
        });

But not any option is working on any browser, can you please help on this. I am doing this for logout, if user logout from one site then it should logout from another site.

Thanks,
Sandy
