JS posłuchaj zmiany lokalizacji
var originalSetItem = localStorage.setItem;
localStorage.setItem = function(key, value) {
var event = new Event('itemInserted');
event.value = value; // Optional..
event.key = key; // Optional..
document.dispatchEvent(event);
originalSetItem.apply(this, arguments);
};
var localStorageSetHandler = function(e) {
alert('localStorage.set("' + e.key + '", "' + e.value + '") was called');
};
document.addEventListener("itemInserted", localStorageSetHandler, false);
localStorage.setItem('foo', 'bar'); // Pops an alert
