ionic+phonegap 实现双击返回键退出功能代码以及插件下载
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);
- })
