【中文标题】Angular Bootstrap DatePicker 指令(Eternicode 版本)未保持打开状态【英文标题】:Angular Bootstrap DatePicker Directive (Eternicode version) not staying open 【发布时间】:2016-01-25 21:37:13 【问题描述】:

我正在努力将Eternicode's Bootstrap Datepicker 集成到我的应用中。我不确定如何将它连接到我的模型,所以我从here 找到了一个使用它的指令。现在我的页面上有日期选择器,但是当我单击输入字段时它不会保持打开状态。日期选择器几乎立即打开和关闭。如果我单击相邻字段并在 datepicker 字段中单击标签,它将按预期保持打开状态。我也很难让它出现在我想要的位置。当它打开时,它位于其他一些元素之下并且不合适。它应该直接在输入字段下方打开。请看下面的截图。

在我的控制器中,我有:

$scope.dateOptions = 
    format: 'dd/mm/yyyy',
    autoclose: false,
    clearBtn: true,
    container: '#datepicker',
    showOnFocus: true,
    startDate: new Date(),
    todayBtn: true,
    todayHighlight: true,
    weekStart: 1,
    zIndexOffset: 5000

$scope.newPost = 
    token: $scope.token,
    post: $scope.post,
    posts: 
        twitter: null,
        facebook: null,
        linkedin: null
    ,
    attachment_url: $scope.attachment_url,
    media_url: $scope.media_url,
    services: 
        twitter: $scope.twitter,
        facebook: $scope.facebook,
        linkedin: $scope.linkedin
    ,
    dateObject: today,
    timeObject: today
;

然后在我的指令中我有:

.directive('bDatepicker', function()
    return 
        require: '?ngModel',
        restrict: 'A',
        link: function ($scope, element, attrs, controller) 
            var updateModel, onblur;

            if (controller != null) 

                updateModel = function (event) 
                    element.datepicker('hide');
                    element.blur();
                ;

                onblur = function () 
                    //we'll update the model in the blur() handler
                    //because it's possible the user put in an invalid date
                    //in the input box directly.
                    //Bootstrap datepicker will have overwritten invalid values
                    //on blur with today's date so we'll stick that in the model.
                    //this assumes that the forceParse option has been left as default(true)
                    //https://github.com/eternicode/bootstrap-datepicker#forceparse
                    var date = element.val();
                    return $scope.$apply(function () 
                        return controller.$setViewValue(date);
                    );
                ;

                controller.$render = function () 
                    var date = controller.$viewValue;
                    if (angular.isDefined(date) && date != null && angular.isDate(date))
                    
                        element.datepicker().data().datepicker.date = date;
                        element.datepicker('setValue');
                        element.datepicker('update');
                     else if (angular.isDefined(date)) 
                        throw new Error('ng-Model value must be a Date object - currently it is a ' + typeof date + ' - use ui-date-format to convert it from a string');
                    
                    return controller.$viewValue;
                ;
            
            return attrs.$observe('bDatepicker', function (value) 
                var options;
                options =  ; //<--- insert your own defaults here!
                if (angular.isObject(value)) 
                    options = value;
                
                if (typeof (value) === "string" && value.length > 0) 
                    options = angular.fromJson(value);
                
                return element.datepicker(options).on('changeDate', updateModel).on('blur', onblur);
            )
        
    
);

最后在我看来:

<input b-datepicker="dateOptions" ng-model="newPost.dateObject" id="datepicker">

我创建了一个小提琴,但我无法让它正常工作。我收到Uncaught Error: [$injector:modulerr] 错误,我不知道如何解决。这是链接:https://jsfiddle.net/kxge3cqf/

【问题讨论】:

你能提供一个小提琴吗? 我创建了一个小提琴,但我无法让它正常工作。我收到Uncaught Error: [$injector:modulerr] 错误,我不知道如何解决。这是链接:jsfiddle.net/kxge3cqf @ACIDSTEALTH 我在本地环境中复制了代码,而[$injector:modulerr] 似乎是因为angular.module('myApp', ['ui.bootstrap']),这里没有定义ui.bootstrap,在从外部链接包含它之后,我又得到了@987654340 @ 和 groups.json 和 socila_media_posts.json 类似,你能提供这些文件或虚拟数据吗?这样我就可以调查了。但是,当我尝试分离出 detepicker 部分以及它有什么问题时。 顺便说一句,如果有帮助,我会为这个 plnkr.co/edit/tmcBSmkY6445KDZpbt2z?p=preview 找到一个有效的 plunk 我已将来自所有三个端点的示例数据添加到帖子中。此外,您上一条评论中的 Plunk 不起作用。日期选择器打开,但无法选择日期。 【参考方案1】:

这似乎是你的问题

$event.stopPropagation();

angular.module('peskyDatepicker', ['ui.bootstrap'])
.controller('DatepickerDemoCtrl', ['$scope',
function ($scope) 
  
  var vm = this;
  
  vm.valuationDate = new Date();
  vm.valuationDatePickerIsOpen = false;
  vm.opens = [];
  
  $scope.$watch(function () 
       return vm.valuationDatePickerIsOpen;
   ,function(value)
      vm.opens.push("valuationDatePickerIsOpen: " + value + " at: " + new Date());
   );
  
  vm.valuationDatePickerOpen = function ($event) 
    
      if ($event) 
          $event.preventDefault();
          $event.stopPropagation(); // This is the magic
      
      this.valuationDatePickerIsOpen = true;
  ;
]);

还有一个关于这个问题的博客 http://blog.johnnyreilly.com/2015/05/angular-ui-bootstrap-datepicker-weirdness.html

在您查看代码时,将尝试准确找出代码中的问题。

编辑1

你为什么不使用 default type="date" 之类的

<input type="date" ng-model="date" value=" date | date: 'yyyy/MM/dd' " />
<br /> date | date: 'dd/MM/yyyy'  

编辑2

好的,尝试了你的代码,只取出了与日期相关的部分,它工作正常。

因此,您的代码中一定有其他原因导致了这种情况。 这是我尝试过的代码,如果有帮助

如果你可以提供一些 git repo 或一个有效的 plunk/fiddle 我可以弄清楚到底是什么问题。但目前这就是我所拥有的。希望对你有帮助

【讨论】:

我将此标记为答案,因为它立即解决了日期选择器打开/关闭的问题。我的老板决定暂时采用更简单的实现(日/月/年下拉菜单),所以我没有机会回去彻底测试解决方案,但根据我在博客文章和 Plunck 中看到的内容,我认为这足以让我下次尝试解决这个问题(可能很快)。谢谢! @ACIDSTEALTH 在回答这个问题时我偶然发现了amsul.ca/pickadate.js/date 或github.com/alongubkin/angular-datepicker(都一样)我喜欢它的 ui,没用过这个,但是 ui 很好 这两个看起来都很恶心。比 Bootstrap 风格好很多。
