angularjs $uimodal 需要更新

Question

我有一个特殊的情况，即使在模式 window 打开后我的数据也会更新。我应该通过在模式弹出窗口上添加一个新项目来刷新模式弹出窗口上的数据。这是 plunker，我试图传递 $rootScope，但是从文档中，意识到传递的默认范围是 $rootScope。我的 plunker link 是 https://plnkr.co/edit/hnMGHfsxPfq8BRCtVxqJ

我正在使用 angular ui bootstrap 并使用 $uibModal 请提出一个我可以尝试的解决方案。在我的 plunker 代码中，即使更新了 $item，我的模式也不会被刷新。

            Having multiple modals open at once is probably bad UX but it's technically possible.

  var $ctrl = this;
  $ctrl.items = ['item1', 'item2', 'item3'];

  $ctrl.animationsEnabled = true;
  $ctrl.additems = function (){
    $ctrl.items.push("item"+($ctrl.items.length+1));

  };
  $ctrl.open = function (size, parentSelector) {
    var parentElem = parentSelector ? 
      angular.element($document[0].querySelector('.modal-demo ' + parentSelector)) : undefined;
    var modalInstance = $uibModal.open({
      animation: $ctrl.animationsEnabled,
      ariaLabelledBy: 'modal-title',
      ariaDescribedBy: 'modal-body',
      templateUrl: 'myModalContent.html',

      controllerAs: '$ctrl',

    setTimeout(function () {

           $ctrl.items.push("item"+($ctrl.items.length+1));
        }, 1000);

    modalInstance.result.then(function (selectedItem) {
      $ctrl.selected = selectedItem;
    }, function () {
      $log.info('Modal dismissed at: ' + new Date());
    });
  };



  $ctrl.toggleAnimation = function () {
    $ctrl.animationsEnabled = !$ctrl.animationsEnabled;
  };
});

// Please note that $uibModalInstance represents a modal window (instance) dependency.
// It is not the same as the $uibModal service used above.

angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($uibModalInstance, items) {
  var $ctrl = this;
  $ctrl.items = items;
  $ctrl.selected = {
    item: $ctrl.items[0]
  };

  $ctrl.ok = function () {
    $uibModalInstance.close($ctrl.selected.item);
  };

  $ctrl.cancel = function () {
    $uibModalInstance.dismiss('cancel');
  };
});

我的问题具体在这里，模态框已经渲染了项目。 ctrl.items 在 1 秒后更新，但是传递项目的模态 window 没有更新。有没有办法可以将 $ctrl.items 的更新发送到模态 window

setTimeout(function () {
                     $ctrl.items.push("item"+($ctrl.items.length+1));
        }, 1000);

Answer 1

你的问题不是很清楚。从你的 plunkr 我看到当原始数据被修改时模态数据得到更新。因此，假设这是您的问题：Javascripts 对象是通过引用复制的。因此，为避免您需要创建该对象的新副本。像这样：

items: function () {
          return angular.copy($ctrl.items);
        }
