我无法弄清楚隔离范围是如何工作的。当我评论指令的范围部分时,我的代码似乎工作正常。谁能解释我错过的东西?

  export function ExampleDirective() {
    'ngInject';

    let directive = {
      restrict: 'E',
      templateUrl: 'someurl.html',
      scope: {
          theFilter: '=' //isolated - if i make the scope global, it works
      },
      controller: ExampleController,
      controllerAs: 'vm',
      bindToController: true,
      link: linkFunc
    };

    function linkFunc(scope, el, attr, vm) {
    }

    return directive;
  }

  class SymptomSearchController {
    constructor ($scope) {
      'ngInject';
    }
  }
<input type="text"
       class="form-control"
       ng-model="theFilter">
<example-directive theFilter="main.theFilter"></example-directive>
export class MainController {  //as 'main'
  constructor() {
    'ngInject';
    this.theFilter = "test";
  }
}

由于你在控制器内部有指令的别名,所以你应该在访问控制器的变量之前使用它。在vm.值中添加ng-model

<input type="text"
       class="form-control"
       ng-model="vm.theFilter">
