# MainDashboardButton

此插槽允许替换文章编辑器中的默认主仪表盘按钮。自 WordPress 6.2 起，站点编辑器中不再提供此功能。
它用于在全屏编辑模式下返回主 wp-admin 仪表盘。

## 示例

### 更改图标

这将把标题栏中的 W 图标按钮替换为关闭图标。

```js
import { registerPlugin } from '@wordpress/plugins';
import { __experimentalMainDashboardButton as MainDashboardButton } from '@wordpress/edit-post';
import { close } from '@wordpress/icons';

const MainDashboardButtonTest = () => (
	<MainDashboardButton>
		<FullscreenModeClose icon={ close } />
	</MainDashboardButton>
);

registerPlugin( 'main-dashboard-button-test', {
	render: MainDashboardButtonTest,
} );
```

### 更改图标和链接

此示例将标题栏中的图标更改为外部链接图标，点击后将跳转至 https://wordpress.org。

```js
import { registerPlugin } from '@wordpress/plugins';
import {
	__experimentalFullscreenModeClose as FullscreenModeClose,
	__experimentalMainDashboardButton as MainDashboardButton,
} from '@wordpress/edit-post';
import { external } from '@wordpress/icons';

const MainDashboardButtonIconTest = () => (
	<MainDashboardButton>
		<FullscreenModeClose icon={ external } href="https://wordpress.org" />
	</MainDashboardButton>
);

registerPlugin( 'main-dashboard-button-icon-test', {
	render: MainDashboardButtonIconTest,
} );
```
