javascript - 如何以单一形式使用多个 Angular UI Bootstrap Datepicker？

Question

我有一个表单，需要为不同的事情设置 2 个或更多日期字段。我尝试了 Angular UI Bootstrap，当表单中只有 1 个日期字段时，它工作得很好。但如果我有多个日期字段，并且我不知道更简单的方法来使其工作，它就会停止工作。

这是我的 HTML 示例:

 <label>First Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" name="dt" ng-model="formData.dt" is-open="opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>      

 <label>Second Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" name="dtSecond" ng-model="formData.dtSecond" is-open="opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>     

我的JS是:

myApp.controller('DatePickrCntrl', function ($scope) {

      $scope.today = function() {
        $scope.formData.dt = new Date();
      };
      $scope.today();

      $scope.showWeeks = true;
      $scope.toggleWeeks = function () {
        $scope.showWeeks = ! $scope.showWeeks;
      };

      $scope.clear = function () {
        $scope.dt = null;
      };

      // Disable weekend selection
      $scope.disabled = function(date, mode) {
        return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
      };

      $scope.toggleMin = function() {
        $scope.minDate = ( $scope.minDate ) ? null : new Date();
      };
      $scope.toggleMin();

      $scope.open = function($event) {
        $event.preventDefault();
        $event.stopPropagation();

        $scope.opened = true;
      };

      $scope.dateOptions = {
        'year-format': "'yy'",
        'starting-day': 1
      };

      $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'shortDate'];
      $scope.format = $scope.formats[0];

});

我是根据样本here实现的。我这里遇到的问题是:

1) 当点击其中一个日期字段时，弹出的日期选择器会变得困惑，似乎在 1 中显示 2 个日期选择器。

2)当我删除 is-open="opened" 属性时，弹出窗口似乎工作正常。但如果没有 is-open="opened"，按钮的 ng-click="open($event) 就不起作用。

3)由于每个日期字段都有不同的 ng-models，因此我无法为任何日期字段设置默认日期，除了第一个带有 ng-model="formData.dt" 的日期字段

我能想到的解决这个问题的唯一长方法是分离每个日期字段的 Controller 。

我想知道其他人在使用 Angular UI Bootstrap 时如何在 1 个表单中实现多个日期字段。

我有 30 个单一形式的 Controller ，没问题。如果您需要在 ng-repeat 上使用相同的概念。

 <label>First Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" 
            name="dt" ng-model="formData.dt" is-open="datepickers.dt" 
            datepicker-options="dateOptions" ng-required="true" 
            close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event,'dt')">
            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>      

 <label>Second Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" 
            name="dtSecond" ng-model="formData.dtSecond" 
            is-open="datepickers.dtSecond" datepicker-options="dateOptions" 
            ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event,'dtSecond')">
            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>     

myApp.controller('DatePickrCntrl', function ($scope) {
      $scope.datepickers = {
        dt: false,
        dtSecond: false
      }
      $scope.today = function() {
        $scope.formData.dt = new Date();

        // ***** Q1  *****
        $scope.formData.dtSecond = new Date();
      };
      $scope.today();

      $scope.showWeeks = true;
      $scope.toggleWeeks = function () {
        $scope.showWeeks = ! $scope.showWeeks;
      };

      $scope.clear = function () {
        $scope.dt = null;
      };

      // Disable weekend selection
      $scope.disabled = function(date, mode) {
        return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
      };

      $scope.toggleMin = function() {
        $scope.minDate = ( $scope.minDate ) ? null : new Date();
      };
      $scope.toggleMin();

      $scope.open = function($event, which) {
        $event.preventDefault();
        $event.stopPropagation();

        $scope.datepickers[which]= true;
      };

      $scope.dateOptions = {
        'year-format': "'yy'",
        'starting-day': 1
      };

      $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'shortDate'];
      $scope.format = $scope.formats[0];

});


 // ***** Q2 ***** somemodel can be just an array [1,2,3,4,5]
 <div ng-repeat="o in somemodel">
 <label>Date Label</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}"
            name="dt{{o}}" ng-model="datepickers.data[o]" 
            is-open="datepickers.isopen[o]" datepicker-options="datepickers.option" 
            ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event,o)">
            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>
  </div>


myApp.controller('DatePickrCntrl', function ($scope) {

      $scope.datepickers = {
        data: {},
        options: {
            'year-format': "'yy'",
            'starting-day': 1
        },
        isopen: {}
      }
      $http.get("get/data/for/some/model", function(result) {
         $scope.somemodel = result;
         for (var i = 0; i < result.length; i++) {
           $scope.datepickers.isopen[result] = false;
           $scope.datepickers.data[result] = new Date(); //set default date.
         }
      });

  // fill in rest of the function
});
