Call a JavaScript function across browser tabs

Question

I have two browser tabs, tab1 and tab2.

I have a function called execute in tab1, which I would like to call from the page in tab2.

Is that possible and if s

Answer 1

There's a tiny open-source component to sync/lock/call code in multiple tabs that allows you send messages between tabs (DISCLAIMER: I'm one of the contributors!)

https://github.com/jitbit/TabUtils

That can be called like this:

TabUtils.BroadcastMessageToAllTabs("messageName", data);

And then in another tab:

TabUtils.OnBroadcastMessage("messageName", function (data) {
    //do something
});

It is based on the onstorage event, you can simply modify the code for you need, it's very simple.
