我用离子编程倒计时应用程序，我在AngularJS中不是很好，因此，我不知道我做错了什么：/也许你可以看看我的代码，它应该有一个按钮，它开始倒计时，如果倒计时结束后，会弹出一条消息。
angular.module('PopupTimer', [])
.controller('PopupCtrl',function($scope, $ionicPopup, $timeout) {
$scope.showAlert = function() {
var alertPopup = $ionicPopup.alert({
title: 'Your Pizza Is Ready!',
template: 'Bon Appétit!'
});
alertPopup.then(function(res) {
console.log('Pizza Is Ready!');
});
};
$scope.timerCountdown = function(res){
var alertPopup = $ionicPopup.alert({
title: 'Your Pizza Is Ready!',
template: 'Bon Appétit!'});
var endtimer = $timeout([200]);
if(endtimer == ([0])) {
return showAlert();
}
}
});
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
angular.module('starter', ['ionic'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
// Don't remove this line unless you know what you are doing. It stops the viewport
// from snapping when text inputs are focused. Ionic handles this internally for
// a much nicer keyboard experience.
cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})

如果你看一下documentation of $timeout，你会发现它的第一个参数是一个函数，应该在指定的延迟之后调用它。
延迟（第二个参数）以毫秒为单位指定。因此，要在5秒后显示警报，您的$sope.timerCountdown函数将如下所示：
$scope.timerCountdown = function(res){
var endtimer = $timeout(
function() {
var alertPopup = $ionicPopup.alert({
title: 'Your Pizza Is Ready!',
template: 'Bon Appétit!'});
},
5000);
};
