Window: online event - Web APIs | MDN
Window: online event Baseline Widely available
The online
event of the Window
interface is fired when the browser has gained access to the network and the value of Navigator.onLine
switches to true
.
Note:
This event shouldn't be used to determine the availability of a particular website. Network problems or firewalls might still prevent the website from being reached.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("online", (event) => { })
ononline = (event) => { }
In addition to the Window
interface, the event handler property ononline
is also available on the following targets:
// addEventListener version
window.addEventListener("online", (event) => {
console.log("You are now connected to the network.");
});
// ononline version
window.ononline = (event) => {
console.log("You are now connected to the network.");
};
