我尝试使用getAllIds()
插件提供的$cordovaLocalNotification
方法为通知创建新ID。
我有一个notify
类,它有一个创建新ID的方法,以及一个用于创建通知的后续方法,如下所示:
var notify = {
latestId: function() {
$cordovaLocalNotification.getAllIds().then(function(result){
return result.length;
})
},
setNotification: function(show) {
$ionicPlatform.ready(function() {
$cordovaLocalNotification.schedule({
id: notify.latestId,
title: show.name + " is out today!",
});
});
}
};
我尝试使用id: notify.latestId
分配结果它似乎是空的承诺对象或其他东西。我尝试了很多不同的设计模式,但我认为我缺少一些基本的东西。任何帮助将不胜感激!
编辑:整个工厂做得很好。
.factory('Notifications', function($cordovaLocalNotification, $ionicPlatform) {
var notify = {
alertTime: function() {
t = new Date();
t.setSeconds(t.getSeconds() + 10);
return t;
},
latestId: function() {
var newId;
$cordovaLocalNotification.getAllIds().then(function(result){
console.log('Get all ids: ' + result) //Returned 2nd: 'Get all ids: 1,0,4,5,3,2'
newId = result.length;
console.log('New id: ' + newId);//Returned 3rd: 'New id: 6'
});
console.log('New id: ' + newId); //Returned first: 'New id: undefined'
return newId;
},
clearAll: function() {
$cordovaLocalNotification.clearAll();
},
setNotification: function(show) {
$ionicPlatform.ready(function() {
$cordovaLocalNotification.schedule({
id: notify.latestId(), // undefined
title: show.name + " is out today!",
firstAt: notify.alertTime()
});
});
}
};
return {
setNotification: function(show){
notify.setNotification(show);
},
clearAll: function(){
notify.clearAll()
},
setAll: function() {
console.log('Set all');
}
};
})

不确定这是否是正确的方法,但它解决了我的问题。我删除了latestId()方法,并围绕setNotification()代码包装了promise,这样它就不会尝试创建通知,直到promise被解决。见下文:
var notify = {
alertTime: function() {
t = new Date();
t.setSeconds(t.getSeconds() + 10);
return t;
},
clearAll: function() {
$cordovaLocalNotification.clearAll();
},
setNotification: function(show) {
$ionicPlatform.ready(function() {
$cordovaLocalNotification.getAllIds().then(function(result){
var newId = result.length;
$cordovaLocalNotification.schedule({
id: newId,
title: show.name + " is out today!",
firstAt: notify.alertTime()
});
});
});
}
};
