angularjs - 绑定(bind) Angular 日期选择器和时间选择器

Question

我想绑定(bind) Angular 时间选择器和日期选择器。我正在使用Angular bootstrap library

根据 timepicker 的文档，它需要 new Date 对象作为最小值和最大值。如果我只是这样设置

var d = new Date();
d.setHours( 2 );
d.setMinutes( 0 );
$scope.minTime = d;

var d = new Date();
d.setHours( 11 );
d.setMinutes( 0 );
$scope.maxTime = d;

<uib-timepicker ng-model="mytime" min="min" max="max" show-meridian="false" min="minTime" max="maxTime"></uib-timepicker>

由于 new Date() 对象，这只适用于今天。

我希望它在我选择的任何一天都能工作。目前，timepicker 并未按要求限制时间。另外，有时时间选择器框边框会变成红色(可能是由于验证错误)，但没有指定错误到底是什么。

为了根据所选日期初始化timepicker，请将dateChange函数替换为:

$scope.dateChange = function() {
    var selectedDate = $scope.dt;
    var min = new Date(selectedDate.getTime());
    min.setHours(2);
    min.setMinutes(0);
    $scope.min = min;

    var max = new Date(selectedDate.getTime());
    max.setHours(4);
    max.setMinutes(0);
    $scope.max = max;
}

工作示例

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function($scope) {
    $scope.format = 'yyyy/MM/dd';
    $scope.min = null;
    $scope.max = null;


     $scope.initTimePicker = function(selectedDate) {
        var min = new Date(selectedDate.getTime());
        min.setHours(2);
        min.setMinutes(0);
        $scope.min = min;

        var max = new Date(selectedDate.getTime());
        max.setHours(4);
        max.setMinutes(0);
        $scope.max = max;
    }

    
    $scope.init = function() {
        $scope.dt = new Date();
        $scope.initTimePicker($scope.dt);
    };
    $scope.init();

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

    $scope.open = function() {
        $scope.popup.opened = true;
    };

   
    $scope.popup = {
        opened: false
    };

   
  
    $scope.dateChange = function() { 
        $scope.initTimePicker($scope.dt);
    }
    

});
