The best way to do what you seem to have asked for is alert("www.example."); – Paul Butcher Commented Jan 11, 2010 at 15:46
- I believe his website uses plug-ins, which shouldn't have access to the URL. – Georg Schölly Commented Jan 11, 2010 at 16:11

Reset to default 2No, but...
In Ecmascript 5, there is support for getters/setters and you can spoof the document reference if accessed from within a scope which redefines it.
Proof:
(function (document) {
alert(document); // -> "spoofed document"
})("spoofed document");
Combined with accessors you can replace the document object. (Javascript 1.5 is needed for accessors.)
No. It is not possible for security reasons.
As others already have noted it is not possible to change the URL without reloading the page.
Note that you can the change the fragment identifier, i.e. the part in the URL after the hash (#) using document.location.hash, but that is probably not good enough for you.
Swap out "document" to another variable, edit it, and swap it back in.
var d = {}
for (var k in document) {
d[k] = document[k];
}
d["location"]="out of this world";
document = d;
You can override it in IE7 or IE8 by making use of independent script tags (but not in modern Firefox or IE9+):
<!DOCTYPE html>
<html><head>
<title>Some title</title>
</head>
<body>
<script>
var _oldDoc = document; // IE < 9 won't work with the code below unless we place it here in its own script tag
</script>
<script>
var document = {};
for (var k in _oldDoc) {
if (navigator.appName == 'Microsoft Internet Explorer' ||
!k.match(/^(location|domain|body)$/) // Cause problems or errors in Mozilla, but Mozilla isn't really creating a new document object anyways
) {
document[k] = _oldDoc[k];
}
}
// Causes problems in Mozilla as we can't get Mozilla to actually overwrite the object
document["location"] = {
href: "out of this world",
toString: function () {
return this.href;
}
};
alert(document.location.href); // "out of this world" in IE < 9
alert(document.location); // "out of this world" in IE < 9
alert(document.title); // 'Some title'
</script>
<script>
alert(document.location.href); // also "out of this world" in IE < 9
alert(document.location); // also gives "out of this world" in IE < 9
alert(document.title); // also 'Some title'
</script>
</body>
</html>
