How To Identify If The Child Window Has Been Closed In Javascript?

i have this page which opens up a popup. i want to refresh the parent after popup has been closed.. i used the function i found in stackoverflow var win = window.open('popup.html

Solution 1:

You wrote the unload event in the wrong place. You added an unload event to the main page instead of to the popup...

var win = window.open("popup.html"); // O.K.

All of this should be in the popup.html page...

function doStuffOnUnload() {
     alert("Unloaded!");
  }

 if (typeof win.attachEvent != "undefined") {
   win.attachEvent("onunload", doStuffOnUnload);
 } elseif (typeof win.addEventListener != "undefined") {
  win.addEventListener("unload", doStuffOnUnload, false);
  }

You can use the unload jquery function:

$(window).unload(doStuffOnUnload);
