添加套件

将套件添加到你的插件中：

import { createPlateEditor } from 'platejs/react';
import { BasicMarksKit } from '@/components/editor/plugins/basic-marks-kit';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    ...BasicMarksKit,
  ],
});
import { createPlateEditor } from 'platejs/react';
import { BasicMarksKit } from '@/components/editor/plugins/basic-marks-kit';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    ...BasicMarksKit,
  ],
});

手动使用方式

安装

pnpm add @platejs/basic-nodes
pnpm add @platejs/basic-nodes

添加插件

在创建编辑器时，将 SuperscriptPlugin 包含到 Plate 插件数组中。

import { SuperscriptPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    SuperscriptPlugin,
  ],
});
import { SuperscriptPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    SuperscriptPlugin,
  ],
});

配置插件

你可以为 SuperscriptPlugin 配置自定义键盘快捷键。

import { SuperscriptPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    SuperscriptPlugin.configure({
      shortcuts: { toggle: { keys: 'mod+period' } },
    }),
  ],
});
import { SuperscriptPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    SuperscriptPlugin.configure({
      shortcuts: { toggle: { keys: 'mod+period' } },
    }),
  ],
});
  • shortcuts.toggle: 定义用于切换上标格式的键盘快捷键。

添加工具栏按钮

你可以向工具栏添加 MarkToolbarButton 来切换上标格式。
