How to prevent iframe from loading in html page?

Question

JavaScript

It is necessary to "protect" the page from displaying third-party iframes on it. For certain reasons, this needs to be done using Javascript. How to track the loading of an iframe or the creation of such elements on the page?

Answer 1

The list of js events help.dottoro.com/larrqqck.php would
probably suit DOMNodeInserted to prevent a new frame from being inserted into the page.

Answer 2

window.framesto help.
A very strange task, of course. Where will the frames come from on the page if you don't add them yourself?

var wF = window.frames;
wF.length&&[].forEach.call(wF, function(frame){
   if(frame.src!="http://site.ru") frame.remove();
});

Answer 3

If anything, the modern and standard solution is the X-FRAME-OPTIONS server header with a value of DENY.
But it is clear that it cannot be exposed from the client side.
