我使用Angular UI Bootstrap並創建一個包含兩個日期選擇器的表單。首先是今天的日期或我們可以選擇的日期，第二天是第一天加上一週7天。Angular UI Bootstrap Datepicker動態日期（變量）
我能夠讓他們最初正確。
$scope.first = new Date(); $scope.second = new Date().setDate(new Date().getDate() + 7);
但是，如果我改變了第一日期選擇的日期，第二屆一個不會做任何改變。我發現{{dt | date:'fullDate' }}捕獲動態日期。我的問題是我如何獲得第一個datepickers的日期是一個變量，並在我的.js文件中操作？那麼只要第一個日期發生變化，我就可以爲我的第二個日期選擇器添加+7天。
如果你正在尋找與2個日期選擇器。如果你在很多地方（頁面）有相同的情況，你可以把它作爲指令。
angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function ($scope) {
$scope.today = function()
{
$scope.dt = new Date();
};
$scope.today();
$scope.clear = function()
{
$scope.dt = null;
};
$scope.dateOptions =
{
formatYear: 'yy',
maxDate: new Date(2020, 5, 22),
minDate: new Date(),
startingDay: 1
};
$scope.open1 = function()
{
$scope.popup1.opened = true;
};
$scope.popup2 = {};
$scope.open2 = function()
{
$scope.popup2.opened = true;
};
$scope.popup1 = {
opened: false
};
$scope.$watch('dt',function(val,old)
{
$scope.opened = false;
$scope.secondDate = new Date().setDate(new Date(val).getDate() + 7);
});
console.log($scope.dt);
