How to handle parents browser windows page features from child windows close in JS

I open a page in browser. There is a link where I click, its fade the page, by putting a layer in the Z-index. At the mean time another Pop up window is also open. When I close the pop up window, the browser remain still faded. I can’t disable the z-index layer that I put in the parents window. Enter code is done in Java Script.

• I believe want you want to do is something like this. On your parent window/page:

  var fadeIn = function fadeIn() {
      // Code to remove added layer
  };
  

  And on your child/popup window/page:

  window.onunload = function () {
      window.opener.fadeIn();
  }
  

• Any JavaScript that resides in the parent page can be called by the child. In your child popup your "close' button click event should have an event similar to this:

  function closePopup()
  { 
      parent.FadeOut();  // Where fadeOut() is a JS function on the parent page
  }
  
  
  //In the Parent Page
  function fadeOut()
  {
     document.getElementById('myLayer').zindex = 0; //Or similar 
  }
