我如何使用指令的属性作为同一类型的另一个指令的属性？
在我提出问题之前，我想指出我是AngularJS的新手，这是学习项目的一部分。 ：）
在我的情况下，我有两个datetime-picker指令实例，我从HTMl中分离出来以使其可重用。其中一个是迄今为止，一个是迄今为止。
我想使用截止日期中的选定日期作为迄今为止的最短可用日期。
但是我似乎无法以某种方式将从日期组件中选择的日期转换为最新组件。即使我确实得到它，它似乎也没有更新，这意味着最新组件只是默认返回到它最初设置的最小日期。
这是指令：
<div class="form-group flex center">
<label class="date-label" for="startdate">{{ ctrl.name }}</label>
<md-datepicker class="date-value" id="startdate" ng-model="ctrl.today"
md-min-date="ctrl.from" md-max-date="ctrl.to"></md-datepicker>
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="hours" data-toggle="dropdown">
Hours
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="hours">

</ul>
</div>
<span class="text-danger" ng-show="shiftForm.plannedStart.$error.required">*Required </span>
</div>
以及它的实施：
(function () {
angular.module("datePicker", [])
.directive("datePicker", function () {
return {
require: 'ngModule',
restrict: "E",
scope: {
ctrl: '=ctrl'
},
templateUrl: "app/views/datepicker.html"
};
});
})();
这就是＆＃34;父母＆＃34;的使用方式：
<form novalidate name="shiftForm" ng-submit="vm.addNewShift()" ng-show="vm.noShiftsFound">
<div>
<date-picker ctrl="from"></date-picker>
</div>
<div>
<date-picker ctrl="to"></date-picker>
</div>
<div class="form-group">
<input type="submit" value="Search" class="btn btn-primary" ng-disabled="shiftForm.$invalid" ng-click="test()"/>
</div>
</form>
来自家长JS的重要摘录：
let vm = this;
vm.myDate = moment().format("DD-MM-YYYY HH:mm:ss");
vm.fromDate = moment().subtract(6, 'hours').format("DD-MM-YYYY HH:mm:ss");
vm.today = new Date();
// for from
vm.minDate = new Date(
vm.today.getFullYear(),
vm.today.getMonth(),
vm.today.getDate() - 1
);
vm.maxDate = new Date(
vm.today.getFullYear(),
vm.today.getMonth(),
vm.today.getDate() + 1
);
$scope.from = {
name: "Planned Start",
from: vm.minDate,
to: vm.maxDate,
today: vm.today
};
$scope.to = {
name: "Planned Finish",
from: vm.today,
to: vm.maxDate,
today: vm.today
};
