The event fires when an application is put into the background.
document.addEventListener("pause", yourCallbackFunction, false);
The pause
event fires when the native platform puts the application into the background, typically when the user switches to a different application.
Applications typically should use document.addEventListener
to attach an event listener once the deviceready
event fires.
document.addEventListener("pause", onPause, false); function onPause() { // Handle the pause event }
<!DOCTYPE html> <html> <head> <title>Pause Example</title> <script type="text/javascript" charset="utf-8" src="cordova-x.x.x.js"></script> <script type="text/javascript" charset="utf-8"> // Wait for device API libraries to load // function onLoad() { document.addEventListener("deviceready", onDeviceReady, false); } // device APIs are available // function onDeviceReady() { document.addEventListener("pause", onPause, false); } // Handle the pause event // function onPause() { } </script> </head> <body onload="onLoad()"> </body> </html>
In the pause
handler, any calls to the Cordova API or to native plug-ins that go through Objective-C do not work, along with any interactive calls, such as alerts or console.log()
. They are only processed when the app resumes, on the next run loop.
The iOS-specific resign
event is available as an alternative to pause
, and detects when users enable the Lock button to lock the device with the app running in the foreground. If the app (and device) is enabled for multi-tasking, this is paired with a subsequent pause
event, but only under iOS 5. In effect, all locked apps in iOS 5 that have multi-tasking enabled are pushed to the background. For apps to remain running when locked under iOS 5, disable the app's multi-tasking by setting UIApplicationExitsOnSuspend to YES
. To run when locked on iOS 4, this setting does not matter.
