source attribute of onstorage event in DOM storage is null

#1 (**permalink**) 10-04-2009, 05:41 AM

Hi,

I'm using DOM storage and the onstorage event.
In msdn blog about IE8 it says that IE8 support the onstorage event which
includes the ource to the window of the origin.
I'm able to see e.url but e.source gives me null.

http://blogs.msdn.com/ie/archive/200...e8-beta-2.aspx
"Finally, we also included improved support of the updated onstorage HTML
5.0 event returned when the storage is changed. We now return the URI when
the local storage is changed, so that handlers for pages can know who carried
out the latest transaction in the storage space in addition to providing the
source to the window of the origin."

My test:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Panel</title>
<script type="text/javascript">
var addStorageEvent = function() {
document.attachEvent("onstorage", function (e) {
alert('storage event');
alert(e.url);
alert(e.source);
});
}

i=1;
var setStorage = function() {
i++;
window.localStorage['test'] = i;
}

var getStorage = function() {
var val = window.localStorage['test'];
alert(val);
}
</script>

</style>
</head>
<body>
<h1>DOM STORAGE TEST</h1>
<button onClick="addStorageEvent();">attach event</button>
<button onClick="setStorage();">set stroage</button>
<button onClick="getStorage();">get storage</button>
</body>
</html>

Thanks

HTML 5 Doctype declaration - http://www.w3schools.com/tags/html5_doctype.asp

I haven't tested your test case, but I assume that in order to use HTML 5
support in IE8, you have to tell the browser that you are using it.

I see that you have made multiple posts to other NG's and MSDN forums. These
are all user Communities, manned by volunteers and enthusiasts. MSFT
moderate but rarely answer questions there.

Your best bet is to post a comment on the IE blog on the thread -
http://blogs.msdn.com/ie/archive/200...e8-beta-2.aspx

MS maintain an issue tracking database for IE8 at connect.microsoft.com. You
can view a list of outstanding 'issues' and wish lists, there.

Regards.

Here is your corrected example... please validate your markup first. Works
as expected for me.

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Panel</title>
<script type="text/javascript">
var addStorageEvent = function() {
document.attachEvent("onstorage", function (e) {
alert('storage event');
alert(e.url);
alert(e.source);
});
}

i=1;
var setStorage = function() {
i++;
window.localStorage['test'] = i;
}

var getStorage = function() {
var val = window.localStorage['test'];
alert(val);
}
</script>

</head>
<body>
<h1>DOM STORAGE TEST</h1>
<button onClick="addStorageEvent();">attach event</button>
<button onClick="setStorage();">set stroage</button>
<button onClick="getStorage();">get storage</button>
</body>
</html>

@rob:

I've changed the DOCTYPE as you suggested.
I also changed the encoding to utf-8 so and now it validates without errors:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

I'm still getting null for the e.source.

When I click on the "attach event" button and then on the "set storage"
button
I'm getting:
alert: 'storage event'
alert: 'http://localhost/storage.html
alert: null

The third alert should be the source window object.
I'm running the html page on IE8 using Apache web server on localhost
on windows XP fully updated.

Am I doing something wrong?

Thanks.

Hi,

e.source is not listed in the MSDN specifications for the onstorage event
argument properties.

http://msdn.microsoft.com/en-us/libr...59(VS.85).aspx

Available Properties

clientX Sets or retrieves the x-coordinate of the mouse pointer's position
relative to the client area of the window, excluding window decorations and
scroll bars.
clientY Sets or retrieves the y-coordinate of the mouse pointer's position
relative to the client area of the window, excluding window decorations and
scroll bars.
url Sets or retrieves the fully qualified URL of the document that fired the
event.
screenX Sets or retrieves the x-coordinate of the mouse pointer's position
relative to the user's screen.
screenY Sets or retrieves the y-coordinate of the mouse pointer's position
relative to the user's screen.
type Sets or retrieves the event name from the event object.

The original IEBlog post was made in the Beta era. As I said it is best to
post back on the IEBlog thread if you want to take it further. We are not
MSFT here, just volunteers, although I did learn a lot from the exercise.

Regards.
