我正在尝试为我的日期时间选择器实现验证。我有一个＆＃39; From＆＃39;日期选择器和＆＃39; To＆＃39;角度局部视图中的datepicker。我希望＆＃39; From＆＃39;日期选择器，如果选择了过去的日期，则显示错误消息，并且＆＃39; To＆＃39;如果所选日期在＆＃39; From＆＃39;之前，则日期选择器应显示错误消息。日期。错误消息应该在选择日期时出现。
我的HTML是：
<div>
<form id="edit-profile" novalidate name="editReservationForm" autocomplete="off" class="form-horizontal">
<fieldset>
<div class="control-group">
<label class="control-label" for="reservation.reservedFrom">Reserved From<sup>*</sup></label>
<div class="controls input-group date" data-provide="datepicker">
<input type="text" class="span4" style="width:150px" name="reservedFrom" placeholder="Reserved From" ng-model="reservation.reservedFrom"
validator="required" required-error-message="Date is required" valid-method="watch" id="startDate" />
<div class="input-group-addon">
<span class="glyphicon glyphicon-th"></span>
</div>
</div> <!-- /controls -->
</div> <!-- /control-group -->
<div class="control-group">
<label class="control-label" for="reservation.reservedTill">Reserved Till<sup>*</sup></label>
<div class="controls input-group date" data-provide="datepicker">
<input type="text" style="width:150px" class="span4" name="reservedTill" placeholder="Reserved Till" ng-model="reservation.reservedTill"
validator="required" required-error-message="Date is required" valid-method="checkErr" id="endDate" ng-change='checkErr()' />
<div class="input-group-addon">
<span class="glyphicon glyphicon-th"></span>
</div>
<span>{{errMessage}}</span>
</div> <!-- /controls -->
</div> <!-- /control-group -->
</fieldset>
</form>
</div>
控制器：
myApp.controller('editReservationController', ['$scope', '$filter', 'reservationResolved', 'pocResolved', 'accountResolved', 'reservationServices', '$location', '$state',
function ($scope, $filter, reservationResolved, pocResolved, accountResolved, reservationServices, $location, $state) {
$scope.reservation = new Object();
$scope.accounts = accountResolved.data;
$scope.pocs = pocResolved.data;
$scope.reservation.employee = reservationResolved.data;
$scope.updateReservation = function () {
if ($scope.editReservationForm.$valid) {
//TODO: fix it properly
$scope.reservation.reservedTill = '';
$scope.reservation.reservedFrom = '';
$scope.reservation.reservedFrom = $('#startDate').val();
$scope.reservation.reservedTill = $('#endDate').val();
reservationServices.updateReservation($scope.reservation).then(function (result) {
$scope.data = result.data;
if (!result.data.error) {
$state.transitionTo('employeeTalentPool', {
id: $state.params.id
});
}
});
}
};
$scope.cancel = function () {
$location.path("/reservations");
};
$scope.checkErr = function () {
var startDate = new Date($scope.reservation.reservedFrom),
endDate = new date($scope.reservation.reservedTill);
$scope.errMessage = '';
if (startDate < new Date()) {
$scope.errMessage = 'Start Date should be greater than or equal today';
return false;
}
if (new Date(endDate) < new Date()) {
$scope.errMessage = 'End Date should be greater than or equal today';
return false;
}
if (endDate < startDate) {
$scope.errorMsg = "End must be after start";
return false;
}
return true;
};
}]);
我是Angular的新手，我试图通过做项目来理解它。任何人都可以检查并提供解决方案吗？
提前致谢...

一种不同的方法，没有显示任何错误消息并满足问题陈述中提到的选择标准
以下是工作解决方案的plunker与您的实现略有不同，我在此示例中使用了bootstrap datepicker，它与datetimepicker几乎相似。希望这会给你一个理解。
在控制器中，我们可以控制在相应的选择中何时以及应禁用from和to日期。使用datepicker提供的minDate我们可以更改到目前为止的最短日期字段来自日期＆＃39; s。
通过这样做，我们可以消除错误信息的显示，这也将满足您的选择标准From＆amp;约会。
angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function($scope) {
$scope.datePicker = {};
$scope.start = new Date();
$scope.end = new Date();
$scope.datePicker.minStartDate = new Date();
// $scope.datePicker.maxStartDate = $scope.end;
$scope.datePicker.minEndDate = $scope.start;
// $scope.datePicker.maxEndDate = $scope.end; //fixed date same as $scope.maxStartDate init value
// watcher to watch the "From" date and set the min date for 'To' datepicker
$scope.$watch('start', function(v) {
$scope.datePicker.minEndDate = v;
$scope.dateOptions2.minDate = v;
});
$scope.dateOptions1 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
// maxDate: $scope.datePicker.maxStartDate,
minDate: $scope.datePicker.minStartDate,
startingDay: 1
};
$scope.dateOptions2 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
// maxDate: $scope.datePicker.maxEndDate,
minDate: $scope.datePicker.minEndDate,
startingDay: 1
};
// Disable weekend selection
function disabled(data) {
var date = data.date,
mode = data.mode;
return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
}
$scope.open1 = function() {
$scope.popup1.opened = true;
};
$scope.open2 = function() {
$scope.popup2.opened = true;
};
$scope.formats = ['dd.MM.yyyy'];
$scope.format = $scope.formats[0];
$scope.altInputFormats = ['M!/d!/yyyy'];
$scope.popup1 = {
opened: false
};
$scope.popup2 = {
opened: false
};
});
在您的HTML中，您可以显示如下
<div ng-controller="DatepickerPopupDemoCtrl">
<h5>From Date</h5>
<p class="input-group">
<input type="text"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-model="start"
is-open="popup1.opened"
datepicker-options="dateOptions1"
close-text="Close"
readonly="true" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open1()">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
<hr>
<h5>To Date</h5>
<p class="input-group">
<input type="text"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-model="end"
is-open="popup2.opened"
datepicker-options="dateOptions2"
close-text="Close"
readonly="true"/>
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open2()">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
</div>
