Angularjs 角度-指令-保留父范围加属性值

因此，我希望编写一个显示给定结构的指令。这些结构可以相互嵌入，因此指令只需在结构中读取，就可以找到其所有子级并相应地显示它们。如果其中一个子结构是另一个结构，则将使用新结构再次调用该指令

这是相当标准的，但是我不想创建新的作用域，因为我需要从主作用域调用函数

我是否可以保留原始范围并仍然通过属性传递信息？还有别的方法吗

我所做的工作如下：

使用原始结构调用structureContent指令

指令是一个模板，它根据结构的类型显示结构的属性。然后它得到它的子元素，如果其中一个子元素是一个结构，则再次调用该指令

就像我说的，这不是问题所在。问题是我还需要保留原来的作用域，因为我需要从那里调用函数

我不能简单地调用父对象，因为可能有多个层次的嵌入式结构

谢谢
