Does onHashChange work in Safari?

问题:

Does onHashChange or hashChange work in Safari? I tested it with Safari 4.0.4 on Windows 7 and it doesn't work for me.

If it doesn't work, is there any solution to track if the hash has changed?

回答1:

In our app we poll to check for changes:

$b.hashCheck = setInterval(
    function(){
        if ( window.location.hash !== $b.C.current_hash){
            $b.C.current_hash = window.location.hash;

            //call the on change action here

        }
    },$b.C.hashCheckDelay
);

$b is the global object we use for our namespace and hashCheckDelay was empirically set at 120ms.
While it looks a bit sad to do this kind of process, there isn't any performance issue on any browser we tested.

In Safari 4.0.4 it's not working yet but in the latest one works fine. And I didn't find any acceptable solutions to track if the hash has changed for those browsers which don't support onHashChange.
