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 isReload read-only property of the FetchEvent interface returns true if the event was dispatched by the user attempting to reload the page, and false otherwise. Pressing the refresh button is a reload while clicking a link and pressing the back button is not.
SyntaxEdit
var reloaded = FetchEvent.isReload
Value
A Boolean.
ExampleEdit
self.addEventListener('fetch', function(event) {
event.respondWith(
if (event.isReload) {
//Return something
} else {
//Return something else
};
);
});SpecificationsEdit
