AngularJS - 初始化DATE输入 [英] AngularJS - Initializing DATE input

问题描述

我有一个应用程序，其中有几个日期字段需要接受来自用户和数据库的值。

I have an application in which there are several date fields that need to accept values from the user as well as from the database.

我发现这个解决方案，但仍然收到错误消息

I found this solution but still get the error message

错误：[ngModel：datefmt]

Error: [ngModel:datefmt]

http ：//errors.angularjs.org/1.5.8/ngModel/datefmt？p0 = 2017-05-03

我的代码是（你可以看到我在评论中做了多次尝试）：

My code is (you can see a number of attempts I made in comments as well):

var xx = $filter("date")(Date.now(), 'yyyy-MM-dd');
var yy = $filter("date")(Date.now(), 'yyyy-MM-dd');

$rootScope.Global.Time_Window_From = xx; // $filter("date")(Date.now(), 'yyyy-MM-dd'); //'2017-05-02' ; //Date.now() ; //$filter("date")(Date.now(), 'yyyy-MM-dd') ;
$rootScope.Global.Time_Window_To   = yy; // $filter("date")(Date.now(), 'yyyy-MM-dd'); //'2017-05-02' ; //Date.now() ; //$filter("date")(Date.now(), 'yyyy-MM-dd') ;

此外，与 DATE 数据交换的最佳方式是什么？一个SQL-Server数据库？

In addition, what would be the best way to exchange DATE data with an SQL-Server database?

提前致谢。

推荐答案

来自Angularjs的文档：

Documentation from Angularjs:

所有与日期相关的输入都要求模型为日期对象。如果模型是别的，那么将抛出此错误

All date-related inputs like require the model to be a Date object. If the model is something else, this error will be thrown

你应该绑定到日期类型输入只有日期类型数据。
按新日期（参数）将生成数据的日期对象。

---

You should bind to date-type input with only date-type data. By new Date(parameter) will generate a date object of your data.

angular.module("app", [])
  .controller("myCtrl", function($scope, $filter) {
    //$scope.testDate = $filter('date')(Date.now(), 'yyyy/MM/dd');
    $scope.testDate = new Date('2017-05-03');
  });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
  <input type="date" ng-model="testDate">
</div>
