如何使用 resolve with Angular 1.5 *components* 和 UI Bootstrap Modal

Question

我正在尝试使用 resolve 将数据传递给 Angular 1.5 component 的 ubi modal。我知道这是可能的，因为它表明 uib 模态文档中的组件支持解析。

component (Type: string, Example: myComponent) - A string reference to the component to be rendered that is registered with Angular's compiler. If using a directive, the directive must have restrict: 'E' and a template or templateUrl set.

It supports these bindings:

(...)

resolve - An object of the modal resolve values. See UI Router resolves for details.

我找到的所有示例都在 open 方法中声明 templateurl/controller。然后将 resolve 中声明的项目注入到控制器中。我正在将 Angular 1.5 组件传递给模态（不是 templateurl/controller），当我尝试从 resolve 注入该项目时，我收到了一个可怕的“未知提供者”错误。

这是我的代码。我正在尝试通过 url.

调用模型的组件的控制器

ParentController.$inject = ['$uibModal'];

function ParentController $uibModal) {
  var $ctrl = this;

  $ctrl.openComponentModal = function(url) {
    var modalInstance = $uibModal.open({
      animation: false,
      component: "ImageModalComponent",
      resolve: {
        url: function() {
          return url;
        }
      }
    });
  };
}

模态组件中的控制器

ImageModalController.$inject = ['url'];

function ImageModalController(url) {
  var $ctrl = this;

  $ctrl.$onInit = function() {
    console.log(url);
  };

}

Answer 1

对于组件，需要将resolve添加到绑定中，然后在隔离范围内可用。也就是说，在声明组件的时候加上resolve: '<'。

模态组件

var template = require('./image_modal.component.html');
var ImageModalController = require('./image_modal.controller');

module.exports = {
  template: template,
  bindings: {
    close: '&',
    resolve: ‘<‘
  },

  controller: ImageModalController
};

调用模型的组件控制器

ParentController.$inject = ['$uibModal'];
function ParentController $uibModal){
  var $ctrl = this;

     $ctrl.openComponentModal = function (urlFromClickEvent) {
        var modalInstance = $uibModal.open({
          animation: false,
          component: "ImageModalComponent",
          resolve: {
            url: function() {
              return url;
            }
          }
        });
      };
}

模态组件的控制器

ImageModalController.$inject = [];
function ImageModalController() {
  var $ctrl = this;
  
  $ctrl.$onInit = function () {
    console.log($ctrl.resolve.url);
  };
}
