IE LocalStorage Event Misfired

Within Internet Explorer 9 & 10, the localStorage implementation fires events unexpectedly (great thread here: Bug with Chrome's localStorage implementation?) Does anybody know

Solution 1:

Changing your script to the following prevents the handling of any storage events in the focused window.

This isn't precisely what you asked, as I believe that would require a patch to the browser, but it causes IE 9/10 to conform to the spec while having no adverse effects on other browsers (other than the global and listeners).

<script type="text/javascript" >
      var focused;

      window.addEventListener('focus', function(){focused=1;}, false);
      window.addEventListener('blur', function(){focused=0;}, false);

      var handle_storage = function (e) {
        if(!focused)
          alert("Storage",focused);
      };

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

</script>

See this fiddle for the updated, conforming behavior.

Edit: The following also works and avoids the listeners at the cost of a runtime check of window focus:

<script type="text/javascript" >

      var handle_storage = function (e) {
        if(!document.hasFocus())
          alert("Storage");
      };

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

</script>
