[Javascript] window location hash

[Guillaume]

Glenn,

Thanks for your reply... I'm not sure of what you mean... I've tryed the 
solution below by setting 2 different values for the same destination.
But the bug remains visible in Safari.
Here's a test page: http://www.hablablow.com/devX/hash/hashG.html

Any other ideas someone ( with Safari under hands )....

Thank you all for helping so far: Glenn, Nick, Matt and Flávio...

I really appreciate.

Regards.

Guillaume.


var hashValue = "bottomPage";
var hashValue1 = "bottomPageA";
window.location.hash = hashValue1;    // an Anchor item one line 
above/below hashValue
window.location.hash = hashValue; 
 
It seems like this would always set your anchor to the proper place 
(bottomPage), even if user has scrolled away from it (a la Nick's 
example), and would never allow hash to be set to same value twice.
