入力コントロールのマスクと検証を持つディレクティブがあります。これは基本的に、ユーザーが 45 (45 分) または 2.5 (2.5 時間 => 150 分) のような時間を入力できる時間入力です。入力はtype=number編集時ですがtype=text、フィルターを使用して結果を表示するときです。

(15 分の増分のみが許可され、フィルターはぼかしイベントに適用されます)

テキストボックスをクリックしたときに初期値が失われることを除いて、すべて正常に機能します。focusイベントでは、値scope.minutesは未定義です。これは90、コントローラーで設定された値である必要があります。理由がわかりません。

vm.minutes1 = 90;に設定するだけMainControllerです。も設定すると動作vm.minutes = 90;します。

angular.module('demoApp', [])
	.controller('MainController', MainController)
  .filter("hoursMinutes", function () {
            return function (mins) {
                if (mins == 0) return "0 mins";
