Warning! You should not call any interactive Javascript in the event handler!
This includes alert() and any other interaction with the user. Ensure that
your handler is "headless".
In your JS event handler, you should strong consider wrapping your JS code in setTimeout.
Otherwise, AJAX calls, for example, will not work.
* willterminate = (UIApplicationWillTerminateNotification)[]
* didlaunch = (UIApplicationDidFinishLaunchingNotification)[https://developer.apple.com/documentation/uikit/uiapplicationdidfinishlaunchingnotification?language=objc]
Only after the deviceready event has fired, add these event listeners within the deviceready handler's function body:
Warning! iOS does not broadcast any event upon termination when the app is already in the background!
``javascript
document.addEventListener("deviceready", function (event1) {
document.addEventListener('willterminate', function (event2) {
/ iOS cordova quirk /
setTimeout(function() {
console.log('terminate event has fired.');
// more JS here!
}, 0);
});
}, false);
`
`javascript`
document.addEventListener('destroy', function () {
// your JS code here!
});
Just register a beforeunload event on the body:
`javascript
window.addEventListener("beforeunload", function (event) {
event.preventDefault();
myUnloadFunction("erase all the things!");
return '';
});
