Window self Property


❮ Window Object




Example


When the "Check window" button is clicked, the function check() is called and
the current window status is checked. If the topmost window (window.top) is
different from the current window (window.self), then output that
"This window is not the topmost window! Am I in a frame?". If the topmost window equals
the current window, then fire the else statement:



function myFunction()
  if (window.top != window.self)

    document.getElementById("demo").innerHTML = "This window is NOT the topmost window!";
   else

    document.getElementById("demo").innerHTML = "This window is the topmost window!";
