Closing a JavaScript window with an onclick event
<p>We have to make a JavaScript that opens a new Window, and then you need to be able to close it again with a click inside the window.
But my code does not work, could someone please provide me an answer to how this is done best?</p>

<pre><code>function swipe() {
   var largeImage = document.getElementById('largeImage');
   var url = largeImage.getAttribute('src');
   var w = largeImage.naturalWidth;
   var h = largeImage.naturalHeight;   

   window.open(url,"Image", "height="+ h +", width="+ w +", resizable=yes");

   var myWindow = window.self;

   myWindow.addEventListener("click", clickHandler);

   var elementIsClicked = false;

   function clickHandler(){ 
    elementIsClicked = true
   }

   function isElementClicked (){
    if(elementIsClicked){
            newWindow.close();
    }
   }

   setInterval(isElementClicked, 500);


}
</code></pre>
