This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The NetworkInformation.onchange event handler contains the code that is fired when connection information changes, and the change is received by the NetworkInformation object.
Syntax
netInfo.onchange = function() { ... }
Examples
// Get the connection type.
var type = navigator.connection.type;
function changeHandler(e) {
// Handle change of connection type here.
}
// Register for event changes:
navigator.connection.onchange = changeHandler;
// Another way: navigator.connection.addEventListener('change', changeHandler);
