HTML5 / JS storage event handler

Question

I\'m using Safari webkit\'s engine together with HTML5 and JS to create an offline application now I\'m using the sessionStorage array to store status of my app

Answer 1

To communicate between multiple tabs we can use storage event. You store a data item in local storage and you will get to know that your local storage is updated.

Check out the code.

      window.addEventListener("storage", storageEventHandler, false);

      function storageEventHandler(evt) {
        alert("storage updated");
      }

      function clickme() {
        localStorage.setItem("someKey", "someValue");
      }

Click Me

Note: storage event only fires in other tabs. Not inside the tab, you are in currently. click^ :)
