如果我的应用程序正在由iframe加载-我可以检测到它吗？

Question

I didn't find the information about this topic in google. Can I detect if my (Rails) application is being loaded from iframe? If yes, can I obtain the url of the iframe? I'd like to do it by both javascript and on the server if it's not possible, if not - whatever way is easier.

Answer 1

through javascript its very easy.

function isInIframe () {
    try {
        return window.self !== window.top;
    } catch (e) {
        return true;
    }
}

server side , check http referer header.

$_SERVER['HTTP_REFERER'] but this is not foolproof.
