It is possible to identify if the page was opened in a pop-up?

I want to do this with javascript or jquery.

I have the test.html page, and if it opens in a pop-up I need a close link to appear'

WINDOW.OPENER

When opening a page using techniques such as window.open, the variable Window.opener is fed with the information of the page that generated the request. If the page has not been opened in this way, returns NULL:

if (window.opener) { // Window.opener recebe os dados da página que gerou a atual
    document.getElementById("fechar").style.display = "block";
} 
#fechar {
  display: none;
}
<a id="fechar">FECHAR</a>
