【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/
这是来自 `social_media_posts.json 的示例:
[
id: 50,
company_id: 94,
employer_id: 3,
post: "testing without attachments",
attachment_url: null,
twitter: true,
facebook: false,
linkedin: false,
post_date: "Fri, Oct 30, 2015",
post_time: " 2:50 PM EDT"
,
total_count: 1
]
这是来自groups.json
的示例:
groups:
1:
id: 1,
name: "Human Resources",
created_at: "2015-10-27T16:23:07.287Z",
updated_at: "2015-11-01T16:11:43.329Z",
company_id: 94
,
2:
id: 2,
name: "Marketing",
created_at: "2015-11-01T15:32:28.988Z",
updated_at: "2015-11-01T16:11:43.354Z",
company_id: 94
这是来自contacts.json
的示例:
contacts:
1:
id: 1,
first_name: "Foo",
last_name: "Bar",
email: "foo.bar@baz.biz",
created_at: "2015-10-27T16:24:00.832Z",
updated_at: "2015-11-01T16:11:52.426Z",
company_id: 94
【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;
;
]);

The left button <em>doesn't</em> work (opens the picker and closes right away).<br />
The right button <em>does</em> work (opens the picker and stays open).<br />
And it's all down to <code>$event.stopPropagation();</code> - funny huh?</code>

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。

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。以上是关于Angular Bootstrap DatePicker 指令(Eternicode 版本)未保持打开状态的主要内容,如果未能解决你的问题,请参考以下文章
