How to subscribe on localStorage but not on sessionStorage events

Question

As far as I understand:

window.addEventListener('storage', function(event){
       ...
}, false);

is subscription on both localStorage and sessionStorage events. Can I subscribe on localStorage events only?

Thanks.

I don't think you can, as you say storage is fired on the window when any storage item changes. You just have to check the storageArea property of the event when you receive it, and ignore the ones from session storage. E.g.:

window.addEventListener('storage', function(event){
    if (event.storageArea === localStorage) {
        // It's local storage
    }
}, false);
