Question

带有datapicker字段的格式化程序中的第一个值无效

使用文本输入的类似格式化工具正常

您可以在下面的代码中看到一个示例：

＆＃13;

/* global angular */

查看控制台日志：第一次格式化程序获取EMPTY值，但必须达到2005（在vm.model中定义）

P.S。在这个例子中，我注意到了另外一个bug：

初始值datepicker未格式化

我得到Tue May 17 2016 18:25:03 GMT+0300 (EEST)但必须2016

我检查数据贴纸相同的版本没有形式，它工作正常。示例：

＆＃13;

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function($scope) {
  $scope.dt = '2005-01-31';

  $scope.today = function() {
    $scope.dt = new Date();
  };

  $scope.today();

  $scope.clear = function() {
    $scope.dt = null;
  };

  $scope.inlineOptions = {
    minDate: new Date(),
    showWeeks: true
  };

  $scope.dateOptions = {
    formatYear: 'yy',
    startingDay: 1
  };

  $scope.open1 = function() {
    $scope.popup1.opened = true;
  };

  $scope.open2 = function() {
    $scope.popup2.opened = true;
  };

  $scope.setDate = function(year, month, day) {
    $scope.dt = new Date(year, month, day);
  };

  $scope.popup1 = {
    opened: false
  };

  $scope.popup2 = {
    opened: false
  };
});

我认为格式化程序在模板初始化时没有第一次调用。

输入[type = number]的示例，如果初始值是字符串，则抛出错误：
