WorkerGlobalScope: offline event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is only available in Web Workers.
The offline
event of the WorkerGlobalScope
fires when the device loses connection to the internet.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
js
addEventListener("offline", (event) => { })
onoffline = (event) => { }
Event type
A generic Event
.
Example
The following code snippet shows an onoffline
handler set inside a worker:
js
self.onoffline = () => {
console.log("Your worker is now offline");
};
The same snippet, but using addEventListener()
:
js
self.addEventListener("offline", () => {
console.log("Your worker is now offline");
});
