> @Fine0830 OK, I got it. > > But there may still have a problem to solve if we send XHR request on `window.onbeforeunload` event. And that is, we should send XHR **Synchronous** instead of **asynchronous** on unload event, to ensure we report successfully. > > So, the `function sendByXhr` @ `src/services/report.ts` may extend a param to control async action. > > And here is some linked article > > * https://stackoverflow.com/questions/4945932/window-onbeforeunload-ajax-request-in-chrome > * https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Synchronous_and_Asynchronous_Requests So this async action make serve side doesn't received data?
