使用Javascript获取根页网址

Question

i am developing facebook application, and i need to get the facebook root page url not iframe, all these methods: document.location , window.location and top.location ... return the iframe url ( my hosting server ) not facebook url.

any suggestions ?

Answer 1

Try parent.location.href . It might not work if the iframe isn't coming from the same domain, and if so you will just need to get the request url referrer with your server code.

Edit: To get the current url in PHP try $_SERVER['HTTP_REFERER']
