Can you explain the distinction between document.body.ononline and navigator.onLine? Do they utilize the same JavaScript API for checking network connectivity status (online/offline)? I have searched on Google but couldn't find a definitive answer. If these two methods have their own API for validating network connection, then which one is considered to be more dependable: document.body.ononline or navigator.onLine?
Check out the NavigatorOnLine.onLine documentation for more information:
The NavigatorOnLine.onLine property indicates whether the browser is currently connected to the internet. It returns a boolean value of true for online and false for offline status. This property also provides updates whenever there are changes in the network connection.
The ononline documentation describes it as an event that triggers when the browser goes online, like so:
window.onload = function() {
document.body.ononline = function() { alert('The browser is now ONLINE'); };
}
On every page load, the document.body.online events are triggered as the browser switches from online to offline mode.
The navigator.onLine property indicates whether the system is currently in offline mode with a Boolean value.
When the navigator.onLine property returns true, it means the system is online, and false indicates offline status. This property updates when the browser's connection to the network changes, such as when users navigate to new pages or scripts request remote content. If internet connection is lost and users click on links shortly after, the property should return false.
