i have 2 pages, page1.html(mypage), and page2.html(external), page1.html is loading page2.html using iframe. page2.html have basically information of user, it contain menus , forms. There is a logout function with below code

$('#inetLogoutId').click(function(event) {
        var logoutMsg = "Are you sure you want to log out?";
        dialogConfirm(logoutMsg, function() {
            top.document.location.href = path + "/logout";
        })
    });

logout not working because of Uncaught DOMException: Blocked a frame with origin "" from accessing a cross-origin frame., what if logout function is modified to window.top.location.href. What's the main difference between these 2.

Thank you

logout not working because of Uncaught DOMException: Blocked a frame with origin "https://example." from accessing a cross-origin frame., what if logout function is modified to window.top.location.href. What's the main difference between these 2.

You cannot have acces to the parent of the iframe when it is on a different domain name.

Although you can solve this in another way: http://madskristensen/post/iframe-cross-domain-javascript-calls

we have to use window.top.location.href = path + "/logout";

This is due to same-origin-policy. You have keep your all files on the same website or host. Same-origin policy prevents access to cross origin.

You can use document.referrer to referrer to the parent window. https://developer.mozilla/en-US/docs/Web/API/Document/referrer#value
