Javascript 在后台实现模态（模态弹出窗口未带到前台）

我的问题是一样的：

我的模态出现在它的背景后面

HTML:

---

问题是我的导航舱内有模型结构。通过将我的模型结构放在导航舱外解决了我的问题

有关层次结构，请参见图片。

是否有办法解决此问题？当将materialize与Angular 2一起使用时，我发现我无法在指令模板中放置模态标记，因为同样的问题也会发生……但是，放置模态代码是合乎逻辑的。我也在使用ui路由使用Angular模板，尽管模态弹出按钮不是我的任何命令的一部分views@tehaaron将模态放在具有作为输入的modalActions。通过这种方式，您可以从不同组件打开和关闭模态
