我在 Angular 中有两个指令。一个必须被排斥在另一个之中。我的问题是，在 transclude 函数运行后，我无法使用简单的 JQuery 选择器访问 DOM。特别是我想编译第一个指令(主题)，然后将它注入(inject)到另一个指令(关于我们)中，这样我就可以访问 DOM 元素 在关于我们的链接功能中。 这是我想要实现的代码:

<section>
    <topic active = "true" title = "Lorem ipsum" icon = "ti-layers">A) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
    <topic title = "Lorem ipsum" icon = "ti-package">B) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
    <topic title = "Lorem ipsum" icon = "ti-stats-up">C) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
    <topic title = "Lorem ipsum" icon = "ti-layout-media-center-alt">D) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
</section>

about-us 和 topic 指令在它们的配置中使用 transclude: true 来编译它们各自的模板。

angular.module('playground', []).directive('topic', function()
{
  return {
    restrict: 'E',
    replace: true,
    templateUrl: 'path/to/topic.html',
    transclude: true,
    scope: true,
    link: function(scope, element, attributes, ctrl, transclude)
    {
        // Playing around with scope

        // Transcluding
        element.find('.tab-content p').append(transclude());
    }
  };
}).directive('section', ['$timeout', function($timeout)
{
  return {
    restrict: 'E',
    replace: true,
    templateUrl: 'path/to/about-us.html',
    transclude: true,
    link: function(scope, element, attributes, ctrl, transclude)
    {
      element.find('.tabs').append(transclude());

      // Now I want to retrieve some DOM contents after the transclude has taken place

      $timeout(function()
      {
        // Playing with DOM and JQuery but sometimes this function run prior of the child transclude function

      });
    }
  };
}]);

为了完整起见，这里是两个模板的代码:

<!-- topic.html -->
<li class="ng-class:active">
  <div class="tab-title">
      <i class="icon ng-class:icon;"></i>
      <span>{{title}}</span>
  </div>
  <div class="tab-content">
    <!-- ng-transclude directive not needed -->
    <p ng-transclude></p>
  </div>
</li>

<!-- about-us.html -->
<section class="bg-secondary pb0" id="about-us">
  <div class="container">
    <div class="row">
      <div class="col-sm-12 text-center">
        <h2 class="mb64 mb-xs-24">About us.</h2>
      </div>
      <div class="col-md-8 col-md-offset-2 col-sm-12 text-center">
        <div class="tabbed-content icon-tabs">
          <ul class="tabs"></ul>
        </div>
      </div>
    </div>
  </div>
</section>

问题是 $timeout 函数被称为 work around 具有完全随机行为，有时有效，有时有效没有。我怎样才能解决这个问题？ 我是否缺少有关嵌入、链接和编译 函数的内容？ 感谢您的每一个回复!

最佳答案

我已经解决了在主指令上设置一个简单的 watcher 并使用 Angular 在链接函数中注入(inject)的 transcludeFn 的问题。

这是代码。如果您遇到类似问题，希望对您有所帮助。

angular.module('playground', []).directive('topic', function()
{
  return {
    restrict: 'AE',
    replace: true,
    templateUrl: 'path/to/topic.html',
    transclude: true,
    scope: true,
    link: function(scope, element, attributes, ctrl, transclude)
    {

      // Playing with scope...

      transclude(scope.$parent, function(clone, parent_scope)
      {
        // Transcluding
        element.find('.tab-content p').append(clone);

        // It's time to render!
        parent_scope.should_render = true;
      });
    }
  };
}).directive('Section', function()
{
  return {
    restrict: 'E',
    replace: true,
    templateUrl: 'path/to/section.html',
    transclude: true,
    scope: {},
    link: function(scope, element, attributes, ctrl, transclude)
    {
      scope.rendered = false;
      scope.should_render = false;

      transclude(scope, function(clone)
      {
        // Transcluding
        element.find('.tabs').append(clone);
      });

      // Setting up a watcher
      var remove_watcher = scope.$watch('should_render', function(should_render)
      {
        if(should_render)
        {
          if(scope.rendered)
          {
            remove_watcher();
            return;
          }

         // Now I can play with the DOM and JQuery.

          scope.rendered = true;
        }
      });
    }
  };
})

现在我可以像这样使用我的指令了:

<section>
    <topic active = "true" title = "Lorem ipsum" icon = "ti-layers">A) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
    <topic title = "Lorem ipsum" icon = "ti-package">B) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</topic>
    <topic title = "Lorem ipsum" icon = "ti-stats-up">C) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    <topic title = "Lorem ipsum" icon = "ti-layout-media-center-alt">D) Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
