Ionic 实现双击返回键退出功能

一、准备Toast插件插件地址：cordova plugin add https://github.com/EddyVerbruggen/Toast-PhoneGap-Plugin.git二：代码

.run(function ($ionicPlatform, $rootScope, $location, $timeout, $ionicHistory, $cordovaToast) {
 $ionicPlatform.ready(function ($rootScope) {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins.Keyboard) {
 cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if (window.StatusBar) {
// org.apache.cordova.statusbar required
StatusBar.styleDefault();
}
});
//双击退出
 $ionicPlatform.registerBackButtonAction(function (e) {
//判断处于哪个页面时双击退出
if ($location.path() == '/tab/news') {
if ($rootScope.backButtonPressedOnceToExit) {
 ionic.Platform.exitApp();
} else {
 $rootScope.backButtonPressedOnceToExit = true;
 $cordovaToast.showShortTop('再按一次退出系统');
 setTimeout(function () {
 $rootScope.backButtonPressedOnceToExit = false;
}, 2000);
}
}
else if ($ionicHistory.backView()) {
 $ionicHistory.goBack();
} else {
 $rootScope.backButtonPressedOnceToExit = true;
 $cordovaToast.showShortTop('再按一次退出系统');
 setTimeout(function () {
 $rootScope.backButtonPressedOnceToExit = false;
}, 2000);
}
 e.preventDefault();
return false;
}, 101);
})
