私はAngularjsアプリケーションをAngular2にアップグレードしています。私はアコーデオンリストで表示するために私のコントローラで繰り返していたJSON配列を持っていました。私は今、私のangular2コンポーネントに同じロジックを書きたいと思っています。Ionic2/Typecript forEachループ実装
myApp.factory('Plan', function() {
var days = [
{ "id": 0,
"name": 'Ihr heutiger Trainingsplan',
"exercises":[
{"id":1,"name":'Best Stretch', "watchedToday": 'false', "type":"body"},
{"id":8,"name":'Farben', "watchedToday": 'false', "type":"memory"},
{"id":2,"name":'Butterfly reverse', "watchedToday": 'false', "type":"body"},
{"id":9,"name":'Punktgenaue Reaktion', "watchedToday": 'false', "type":"memory"},
{"id":3,"name":'SquatRow', "watchedToday": 'false', "type":"body"},
{"id":10,"name":'Loslassen', "watchedToday": 'false', "type":"memory"},
// {"id":13,"name":'Wortpaare 1', "watchedToday": 'false', "type":"memory"},
{"id":4,"name":'Plank', "watchedToday": 'false', "type":"body"},
{"id":11,"name":'Wortpaare', "watchedToday": 'false', "type":"memory"}, //word-pair 1 : just show words
{"id":5,"name":'Push Up', "watchedToday": 'false', "type":"body"},
{"id":12,"name":'Wortschatz', "watchedToday": 'false', "type":"memory"},
// {"id":14,"name":'Wortschatz 1', "watchedToday": 'false', "type":"memory"}, // word-pair 2 : actual game
{"id":6,"name":'Side Plank', "watchedToday": 'false', "type":"body"},
{"id":7,"name":'Squat', "watchedToday": 'false', "type":"memory"}
]
}
];
return {
all: function() {
return days;
},
get: function(dayId) {
// Simple index lookup
return days[dayId];
}
}
});
//In my controller
$scope.days=Plan.all();
//Iterate over the list
angular.forEach($scope.days, function(value1, key){
//iterate over the list of exercises
angular.forEach(value1.exercises, function(value2, key){
// Check if the fetched exercise id is same as current exercise from the frontend list and check if the fetched date is today
if(value2.id==game_type && $scope.today === current_date_memory){
// If the fetched date is todat i.e. exercise was rated today: set the flag for watchedTodat to true
value2.watchedToday=true;
}
});
});
は、どのように私はそれがangular2コードに変換することができます：私は次のコードしていた
？
私はこれまでのところ、私のコンポーネントを持っている：
export class ContactPage {
days = [
{ "id": 0,
"name": 'Ihr heutiger Trainingsplan',
"exercises":[
{"id":1,"name":'Best Stretch', "watchedToday": 'false', "type":"body"},
{"id":8,"name":'Farben', "watchedToday": 'false', "type":"memory"},
{"id":2,"name":'Butterfly reverse', "watchedToday": 'false', "type":"body"},
{"id":9,"name":'Punktgenaue Reaktion', "watchedToday": 'false', "type":"memory"},
{"id":3,"name":'SquatRow', "watchedToday": 'false', "type":"body"},
{"id":10,"name":'Loslassen', "watchedToday": 'false', "type":"memory"},
// {"id":13,"name":'Wortpaare 1', "watchedToday": 'false', "type":"memory"},
{"id":4,"name":'Plank', "watchedToday": 'false', "type":"body"},
{"id":11,"name":'Wortpaare', "watchedToday": 'false', "type":"memory"}, //word-pair 1 : just show words
{"id":5,"name":'Push Up', "watchedToday": 'false', "type":"body"},
{"id":12,"name":'Wortschatz', "watchedToday": 'false', "type":"memory"},
// {"id":14,"name":'Wortschatz 1', "watchedToday": 'false', "type":"memory"}, // word-pair 2 : actual game
{"id":6,"name":'Side Plank', "watchedToday": 'false', "type":"body"},
{"id":7,"name":'Squat', "watchedToday": 'false', "type":"memory"}
]
}
];
constructor(public navCtrl: NavController) {
}
}
