我有一个复杂的场景,我需要帮助.

我有一个指令(称为TagDirective),它放在我的应用程序的多个元素上.我有另一个指令(QueryDirective),它需要引用TagDirective其主机元素上存在的所有实例,以及层次结构中它上面的所有元素.

例:

<div appTag="a">
  <div appTag="b">
    <div appTag="c">
      <div appTag="d">
        <div appQuery>
          <!-- In here I want to have a reference to TagDirectives instances
              d,c,b,a -->
        </div>
      </div>
    </div>
    <div appTag="e">
      <div appTag="f">
        <div appTag="g">
          <div appTag="h">
            <div appQuery>
              <!-- In here I want to have a reference to TagDirectives instances
                  h,g,f,e,b,a -->
            </div>
          </div>
        </div>
        <div appQuery>
          <!-- In here I want to have a reference to TagDirectives instances
              f,e,b,a -->
        </div> …
