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 ItalicPlugin 包含到你的 Plate 插件数组中。

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

配置插件

你可以为 ItalicPlugin 配置自定义快捷键。

import { ItalicPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    ItalicPlugin.configure({
      shortcuts: { toggle: 'mod+i' },
    }),
  ],
});
import { ItalicPlugin } from '@platejs/basic-nodes/react';
import { createPlateEditor } from 'platejs/react';
 
const editor = createPlateEditor({
  plugins: [
    // ...其他插件,
    ItalicPlugin.configure({
      shortcuts: { toggle: 'mod+i' },
    }),
  ],
});
