FetchEvent.isReload

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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.

Syntax

var reloaded = FetchEvent.isReload

Value

A boolean value.

Example

self.addEventListener('fetch', function(event) {
  event.respondWith(
    if (event.isReload) {
      //Return something
    } else {
      //Return something else
    };
  );
});
