I am in the process of developing a UWP app using JavaScript. When I click the Back Button, it currently just closes the app. However, I am looking to modify this behavior to instead trigger a JavaScript function.
If anyone has knowledge and experience with creating a Windows Runtime component and invoking it from JavaScript in order to manage the Back Button press event, your guidance and code examples would be greatly appreciated.
let systemNavigation = Windows.UI.Core.SystemNavigationManager.getForCurrentView();
function initializeApp(){
// Setting up backRequested event
if (systemNavigation !== null) {
systemNavigation.addEventListener("backrequested", handleBackRequest, false);
}
}
function handleBackRequest() {
if (window.location.href.indexOf("/default.html") === -1) { // If not on home page, go back
// Navigate back
window.history.back();
}
}
