localStorage object is undefined in IE

Question

I'm using localStorage in my JS application and I was wondering why IE9 claims localStorage == undefined. As far as I know, IE8 supports it, is here any way to get it working in the new version?

Answer 1

Are you testing this on a local HTML file? i.e. a file:/// URL?

localStorage is only available on HTTP websites. That hasn't changed in IE9 Dev Preview.

Answer 2

IE 11 WORKS

All you need two do add file://127.0.0.1 to the trusted zones under the security tab (NOTE: make sure https check box IS not checked) add this line to the top or your script, depending on your code you may not need to unless you get could not connect to the internet.

!localStorage && (l = location, p = l.pathname.replace(/(^..)(:)/, "$1$$"), (l.href = l.protocol + "//127.0.0.1" + p));  if (typeof(Storage) != "undefined") {     // Store     localStorage.setItem("lastname", "Smith");     // Retrieve     alert(localStorage.getItem("lastname")); } else {     alert("Sorry, your browser does not support Web Storage..."); }
