<html><body><h1>The Storage Event</h1><p>The Storage Event is triggered when there is a change in the window's storage area.</p><p><strong>Note:</strong> The storage event is only triggered when a window <strong>other than itself</strong> makes the changes.</p><p>Therefore, in this example, a hidden iframe is used. The hidden iframe has one mission; whenever it is targeted, it will change the value of a local storage item named "mytime" with the value of the current date in milliseconds.</p><h1>The url Property</h1><p>The url property belongs to the Storage Event object, and returns the url of the page where the item was changed.</p><p>The url of the page where the item was changed:</p><p id="demo"></p><script>window.addEventListener("storage", myFunction);function myFunction(event) { x = event.url; document.getElementById("demo").innerHTML = x;}</script><iframe src="test_local_storage.html" style="display:none"></iframe></body><!-- Mirrored from www.w3schools.com/jsref/tryit.asp?filename=tryjsref_event_storage_url by HTTrack Website Copier/3.x [XR&CO'2014], Mon, 27 Jan 2020 03:17:04 GMT --></html>
