Comments
Use this function if you want to know when other scripts do localStorage.set().
Important: the "update" event does not react on localStorage.set() calls in current script.
Example
To see how localStorage.on("update") works you'll need two scripts:
The "Listener" script:
localStorage.on("update", function(entry, value, script) {
console.log("localStorage got updated:", entry, "=", value, "by script", script);
exit();
});
The "Initiator" script:
localStorage.set("data", "data from 1");
exit();
How to run:
- Launch the "Listener" script (it will keep running)
- Launch the "Initiator" script (it will run and stop)
- Now switch to the "Listener" script and check the runtime logs of "Listener"
