Javascript communication between browser tabs/windows [duplicate]

Answer 1

You can do this via local storage API. Note that this works only between 2 tabs. you can't put both sender and receiver on the same page:

On sender page:

localStorage.setItem("someKey", "someValue");

On the receiver page

    $(document).ready(function () {

        window.addEventListener('storage', storageEventHandler, false);

        function storageEventHandler(evt) {
            alert("storage event called key: " + evt.key);
        }
    });
