最初在范围内设置值时，Datepicker-popup格式化不起作用 [英] Datepicker-popup formatting not working when value set initially in scope

问题描述

我在Plunker上使用此自定义指令使用Angular UI引导日期选择器弹出窗口（

解决方案

终于找到了解决方案。我从Angular-UI-Bootstrap更改为uib-datepicker指令，现在它在控制器中设置日期时正确格式化日期！这是我的指令中的HTML模板供参考：

  template：'< p class =input-group>' + 
'< input type =textstyle =cursor：pointerclass =form-controluib-datepicker-popup ={{format}}'+ 
'ng- model =ngModelis-open =open'+ 
'min-date =minDatemax-date =maxDate'+ 
'datepicker-options =dateOptionsdate-disabled =禁用（日期，模式）'+ 
'ng-required =dtpRequiredclose-text =关闭ng-readonly =ngReadonlyng-click =openPopup（）/>' + 
'< span class =input-group-btn>'+ 
'< button type =buttonclass =btn btn-defaultng-click =openPopup（ $ event）>'+ 
'< i class =fa fa-calendar>< / i>< / button>'+ 
'< / span>'+ 
'< / p>'
  

I am using the Angular UI bootstrap date picker popup using this custom directive on Plunker (http://plnkr.co/edit/053VJYm1MpZUiKwFTfrT?p=preview):

//Module
var userModule = angular.module("userModule",['ui.bootstrap']);

//Controller
userModule.controller("sampleController", ['$scope', function ($scope) {
    $scope.minDate = new Date();
}]);

//Directive code
userModule.directive('datePicker', [function (dateFilter) {
    return {
        restrict: 'E',
        require: 'ngModel',
        scope: {
            ngModel: '=',
            ngReadonly: '=?',
            minDate: '=?',
            maxDate: '=?',
            dtpRequired: '=?',
            dateOptions: '=?'
        },
        template: '<p class="input-group">' +
                    '<input type="text" style="cursor:pointer" class="form-control" datepicker-popup="{{format}}"' +
                        'ng-model="ngModel" is-open="opened"' +
                            'min-date="minDate" max-date="maxDate"' +
                                'datepicker-options="dateOptions" date-disabled="disabled(date, mode)"' +
                                 'ng-required="dtpRequired" close-text="Close" ng-readonly="ngReadonly" ng-click="openPopup()" />' +
                         '<span class="input-group-btn">' +
                            '<button type="button" class="btn btn-default" ng-click="openPopup($event)">' +
                                '<i class="fa fa-calendar"></i></button>' +
                        '</span>' +
                    '</p>',
        controller: function ($scope) {
            // check if it was defined.  If not - set a default
            $scope.dateOptions = $scope.dateOptions || {
                formatYear: 'yy',
                startingDay: 1,
                showWeeks: false
            };

            $scope.openPopup = function ($event) {
                if ($event !== undefined) {
                    $event.stopPropagation();
                }
                $scope.opened = true;
            };

            $scope.format = 'dd MMMM yyyy';
        },
        link: function ($scope, element, attrs, controller) {
            //remove the default formatter from the input directive to prevent conflict
            controller.$formatters.shift();
        }
    };
}]);

This is working fine and the date is formatted fine when selecting a date from the calendar popup. However if I set a date of the ng-model in the controller, the date isn't formatted as 'dd MMMM yyyy' and is returned as a date string like Sat Oct 01 2016 01:00:00 GMT+0100 (GMT Daylight Time). However in the Plunker, I am able to set a date in the controller and it is formatted fine. Here is my HTML for the date picker:

<date-picker ng-model="startDate.value" datepicker-options="dateOptions" min-date="minDate" ng-readonly="true"></date-picker>

In my controller startDate.value = new Date();

I'm not sure where the problem could be. The image below shows what I'm getting back.

解决方案

Finally found a solution for this. I changed to the uib-datepicker directive from Angular-UI-Bootstrap and it now formats the date correctly when the date is set in the controller! Here's my HTML template from my directive for reference:

template: '<p class="input-group">' +
            '<input type="text" style="cursor:pointer" class="form-control" uib-datepicker-popup="{{format}}"' +
                'ng-model="ngModel" is-open="opened"' +
                    'min-date="minDate" max-date="maxDate"' +
                        'datepicker-options="dateOptions"date-disabled="disabled(date, mode)"' +
                         'ng-required="dtpRequired" close-text="Close" ng-readonly="ngReadonly" ng-click="openPopup()" />' +
                 '<span class="input-group-btn">' +
                    '<button type="button" class="btn btn-default" ng-click="openPopup($event)">' +
                        '<i class="fa fa-calendar"></i></button>' +
                '</span>' +
            '</p>'
