: Is there a way to tell if a page load was done inside a frame, iframe, etc.? Wondering if there's a way to detect a page load was done inside a frame, iframe, etc. (likely via JavaScript)

@Pope3001725

if (top.location.href != window.location.href) {
alert("In A Frame");
}


The limit is if JavaScript is turned off it won't work.

You can also use the X-Frame-Options HTTP header. This header tells a web browser whether or not to allow a web page to be framed in another web page. This includes <frame> and <iframe> tags.

There are two possible values for this header:

DENY - This setting prevents any pages served from being placed in a frame even if it is on the same website it originates from. should be used if you never intend for your pages to be used inside of a frame.

SAMEORIGIN - This setting allows pages to be served in a frame of a page on the same website. If an external site attempts to load the page in a frame the request will be denied.

This header works in Internet Explorer 8.0, Firefox 3.6.9, Opera 10.50, Safari 4.0, and Chrome 4.1.
