我昨天开始使用AngularJS 1.3，我发现的一个问题是Datepicker中的初始日期不是定义的格式。 选择日期后，日期格式正确。
AngularJS 1.2.10的初始格式是正确的，可以通过注释掉脚本标记在示例中看到。
如何将初始格式设置为正确？

app.controller("DatepickerDemoCtrl", function ($scope) {
$scope.format = 'dd-MMMM-yyyy';
$scope.today = function() {

$scope.today();
$scope.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
});

不确定1.3中究竟发生了什么变化，但有一个bug report for this。
这是一个初始值的drop-in指令，用于修复问题，直到修复bug为止。这是一个演示Plunker。
angular.module('myApp').directive('datepickerPopup', function (dateFilter, datepickerPopupConfig) {
return {
restrict: 'A',
priority: 1,
require: 'ngModel',
link: function(scope, element, attr, ngModel) {
var dateFormat = attr.datepickerPopup || datepickerPopupConfig.datepickerPopup;
ngModel.$formatters.push(function (value) {
return dateFilter(value, dateFormat);
});
}
};
});

app.controller("DatepickerDemoCtrl", function ($scope,$filter) { .. // $filter added
$scope.today = function() {
$scope.dt = $filter('date')(new Date(), $scope.format);
};
<input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" ... // {{format}} added
请检查这三项修改。
