AngularJS - Check if selected date is equal to next business date
提问by sharic19
I am trying to check if selected date is equal to next business date using AngularJS. If selected date is not equal to the next business date, a warning will be shown, like twitter bootstrap's alert-warning, using ng-show angularjs directive.
我正在尝试使用 AngularJS 检查所选日期是否等于下一个营业日期。如果所选日期不等于下一个营业日期，则会使用 ng-show angularjs 指令显示警告，例如 twitter bootstrap 的警报警告。
Here's the current Fiddlefor this.
这是当前的Fiddle。
Currently, the next business day is returned by getNextBusinessDay() $scope function. The comparison is triggered by ng-changed="comparisonResult()" which should return true/false based on comparison, but isn't working.
目前，下一个工作日由 getNextBusinessDay() $scope 函数返回。比较由 ng-changed="comparisonResult()" 触发，它应该根据比较返回真/假，但不起作用。
Here my html code:
这是我的 html 代码：
<body ng-app="angularjs-starter" ng-controller="MainCtrl">
<div class="container">
<section id="datepicker">
<div class="bs-docs-example">
<form class="form-horizontal well">
<div class="control-group input-append">
<label for="inputDatepicker" class="label" style="margin-right:6px;">
Selected Date</label>
<input id="inputDatepicker" class="input-small" type="text"
ng-model="selectedDate" ng-changed="comparisonResult()"
data-date-format="dd/mm/yyyy" bs-datepicker>
<button type="button" class="btn" data-toggle="datepicker">
<i class="icon-calendar"></i></button>
</div>
</form>
</div>
</section>
</div>
</body>
Here's my js code:
这是我的js代码：
var app = angular.module('angularjs-starter', ['$strap.directives']);
app.controller('MainCtrl', function($scope, $window, $location) {
// Datepicker directive
$scope.selectedDate = null;
$scope.getNextBusinessDay = function() {
return $scope.getDeliveryDateObj(1);
}
$scope.getDeliveryDateObj = function(businessDaysLeftForDelivery){
var now = new Date();
var dayOfTheWeek = now.getDay();
var calendarDays = businessDaysLeftForDelivery;
var deliveryDay = dayOfTheWeek + businessDaysLeftForDelivery;
if (deliveryDay >= 6) {
businessDaysLeftForDelivery -= 6 - dayOfTheWeek; // deduct this-week days
calendarDays += 2; // count this coming weekend
deliveryWeeks = Math.floor(businessDaysLeftForDelivery / 5); // how many whole weeks?
calendarDays += deliveryWeeks * 2; // two days per weekend per week
}
now.setTime(now.getTime() + calendarDays * 24 * 60 * 60 * 1000);
now.setUTCHours(0);
now.setUTCMinutes(0);
now.setUTCSeconds(0);
now.setUTCMilliseconds(0);
return now;
}
$scope.getNextBusinessDay();
$scope.comparisonResult = function() {
if($scope.selectedDate == $scope.getNextBusinessDay()) {
return false;
} else {
return true;
}
};
});
Any help or suggestion will be appreciated. Thanks in advance. :)
任何帮助或建议将不胜感激。提前致谢。:)

When comparing dates, use a.getTime() == b.getTime()instead of a == b.
比较日期时，请使用a.getTime() == b.getTime()代替a == b。

It is 2017 now, if you use Angular >= v1.2 you can use angular.equals(date1, date2)
现在是 2017 年，如果你使用 Angular >= v1.2 你可以使用 angular.equals(date1, date2)
