`before-close` only works when user clicks the close icon or the backdrop. If you have buttons that close the Dialog in the `footer` named slot, you can add what you would do with `before-close` in the buttons' click event handler.

### Nested Dialog
|
||||
If a Dialog is nested in another Dialog, `append-to-body` is required.
|
||||
:::demo Normally we do not recommend using nested Dialog. If you need multiple Dialogs rendered on the page, you can simply flat them so that they're siblings to each other. If you must nest a Dialog inside another Dialog, set `append-to-body` of the nested Dialog to true, and it will append to body instead of its parent node, so both Dialogs can be correctly rendered.

If the variable bound to `visible` is managed in Vuex store, the `.sync` can not work properly. In this case, please remove the `.sync` modifier, listen to `open` and `close` events of Dialog, and commit Vuex mutations to update the value of that variable in the event handlers.

### 嵌套的 Dialog
|
||||
如果需要在一个 Dialog 内部嵌套另一个 Dialog，需要使用 `append-to-body` 属性。
|
||||
:::demo 正常情况下，我们不建议使用嵌套的 Dialog，如果需要在页面上同时显示多个 Dialog，可以将它们平级放置。对于确实需要嵌套 Dialog 的场景，我们提供了`append-to-body`属性。将内层 Dialog 的该属性设置为 true，它就会插入至 body 元素上，从而保证内外层 Dialog 和遮罩层级关系的正确。

如果 `visible` 属性绑定的变量位于 Vuex 的 store 内，那么 `.sync` 不会正常工作。此时需要去除 `.sync` 修饰符，同时监听 Dialog 的 `open` 和 `close` 事件，在事件回调中执行 Vuex 中对应的 mutation 更新 `visible` 属性绑定的变量的值。
