forcing local storage events to fire in the same window

Question

From many sources, I have found that the local storage events only fire in windows/tabs that did not originate the change.

My question is, is there any way I could detect change from the same window? Or perhaps override the functionality to force the event to fire within the same window/tab?

It just seems impractical to not include the option, but I cannot find a way to do it.

Thanks

FYI, here is what I ended up with.

localStorage.setItem('selectedOrgs', JSON.stringify(this.selectedOrgs));

// trigger the event manually so that it triggers in the same window
// first create the event
var e = $.Event("storage");

// simulate it being an actual storage event
e.originalEvent = {
    key: 'selectedOrgs',
    oldValue: prev,
    newValue: JSON.stringify(this.selectedOrgs)
};

// Now actually trigger it
$(window).trigger(e);

Note: I only use oldValue and newValue.. if you use other attributes make sure and set them appropriately.

You could also overwrite localStorage.setItem so that it fires in the current window in a similar way.
