快速开始
1. 安装依赖
确保项目中已安装必要的依赖:
bash
npm install react-quill quill-blot-formatter antd
# 或
yarn add react-quill quill-blot-formatter antd
2. 基础使用
tsx
import React, { useState } from 'react';
import RichTextEditor from './RichTextEditor';
function App() {
const [content, setContent] = useState('');
return (
<div style={{ padding: '20px' }}>
<h2>富文本编辑器示例</h2>
<RichTextEditor
value={content}
onChange={setContent}
placeholder="请输入内容..."
maxLength={1000}
showCharCount={true}
style={{ height: '300px' }}
/>
<div style={{ marginTop: '20px' }}>
<h3>输出内容:</h3>
<div dangerouslySetInnerHTML={{ __html: content }} />
</div>
</div>
);
}
export default App;
3. 表单集成
tsx
import { Form, Button } from 'antd';
import RichTextEditor from './RichTextEditor';
function FormExample() {
const [form] = Form.useForm();
const onFinish = (values: any) => {
console.log('表单数据:', values);
};
return (
<Form form={form} onFinish={onFinish}>
<Form.Item
name="content"
label="内容"
rules={[{ required: true, message: '请输入内容' }]}
>
<RichTextEditor
placeholder="请输入内容..."
maxLength={500}
showCharCount={true}
style={{ height: '200px' }}
/>
</Form.Item>
<Form.Item>
<Button type="primary" htmlType="submit">
提交
</Button>
</Form.Item>
</Form>
);
}

图片工具实现详解

} as const;
};
架构设计特点
1. 状态管理策略
使用单一的 stateRef
管理所有运行时状态,避免多个 useState
导致的重渲染问题:
typescript
interface RichTextToolsState {
editor: { element?: HTMLElement; quill?: any };
preview: { container: HTMLDivElement | null; currentSrc: string | null; visible: boolean };
modal: { container: HTMLDivElement | null; visible: boolean; /* ... */ };
icons: { previewIcon: HTMLDivElement | null; /* ... */ };
observers: { resize: ResizeObserver | null; /* ... */ };
handlers: { editorClick?: (e: Event) => void; /* ... */ };
}
2. 模块化设计
将功能按领域划分为独立模块:
- preview: 图片预览管理
- sizeModal: 尺寸编辑弹窗
- icons: 悬浮工具图标
- keyGuard: 键盘事件守卫
- editorLifecycle: 编辑器生命周期
3. 观察者模式
使用多种观察者监听不同类型的变化:
- ResizeObserver: 监听图片尺寸变化
- MutationObserver: 监听DOM属性变化和编辑器内容变化
- 事件监听器: 监听滚动、窗口缩放等事件
样式配置系统
1. 主要样式文件 (index.module.less)
这是组件的主要样式文件,使用CSS Modules提供样式隔离:
less
.richTextContainer {

value?: string;
onChange?: (value: string) => void;
onBlur?: (value: string) => void;
disabled?: boolean;
placeholder?: string;
maxLength?: number;
showCharCount?: boolean;
style?: React.CSSProperties;
uploadApi?: string;
onUpload?: (file: File) => Promise<string | null>;
}
工具栏配置
组件支持自定义工具栏按钮:
typescript
const modules = {
toolbar: {
container: [
[{ header: [1, 2, 3, false] }],
['bold', 'italic', 'underline', 'strike'],
[{ color: [] }, { background: [] }],
[{ list: 'ordered' }, { list: 'bullet' }],
[{ align: [] }],
['image'],
['clean'],
],
handlers: {
image: imageHandler,
},
},
};
使用场景示例
1. 基础文本编辑器
tsx
import React, { useState } from 'react';
import RichTextEditor from './RichTextEditor';
const BasicEditor = () => {
const [content, setContent] = useState('');
return (
<RichTextEditor
value={content}
onChange={setContent}
placeholder="开始编辑你的内容..."
style={{ height: '200px' }}
/>
);
};
2. 带字符限制的编辑器
tsx
import React, { useState } from 'react';
import RichTextEditor from './RichTextEditor';
const LimitedEditor = () => {
const [content, setContent] = useState('');
return (
<RichTextEditor
value={content}
onChange={setContent}
placeholder="最多输入500个字符..."
maxLength={500}
showCharCount={true}
style={{ height: '250px' }}
/>
);
};
3. 表单集成使用
tsx
import React from 'react';
import { Form, Button } from 'antd';
import RichTextEditor from './RichTextEditor';
const FormEditor = () => {
const [form] = Form.useForm();
const onFinish = (values: any) => {
console.log('表单数据:', values);
};
return (
<Form form={form} onFinish={onFinish}>
<Form.Item
name="description"
label="产品描述"
rules={[
{ required: true, message: '请输入产品描述' },
{ min: 10, message: '描述至少10个字符' }
]}
>
<RichTextEditor
placeholder="请详细描述产品特性..."
maxLength={2000}
showCharCount={true}
style={{ height: '300px' }}
/>
</Form.Item>
<Form.Item>
<Button type="primary" htmlType="submit">
提交
</Button>
</Form.Item>
</Form>
);
};
4. 带图片上传的富文本编辑器
tsx
import React, { useState } from 'react';
import RichTextEditor from './RichTextEditor';
const ImageUploadEditor = () => {
const [content, setContent] = useState('');
// 自定义图片上传处理
const handleUpload = async (file: File): Promise<string | null> => {
try {
const formData = new FormData();
formData.append('file', file);
const response = await fetch('/api/upload', {
method: 'POST',
body: formData,
});
const result = await response.json();
return result.url; // 返回图片URL
} catch (error) {
console.error('上传失败:', error);
return null;
}
};
return (
<div>
<h3>支持图片的富文本编辑器</h3>
<p>提示:可以通过以下方式添加图片:</p>
<ul>
<li>点击工具栏的图片按钮</li>
<li>直接粘贴剪贴板中的图片</li>
<li>拖拽图片文件到编辑区域</li>
</ul>
<RichTextEditor
value={content}
onChange={setContent}
placeholder="支持图片粘贴和拖拽上传的富文本编辑器..."
maxLength={3000}
showCharCount={true}
onUpload={handleUpload}
style={{ height: '400px' }}
/>
</div>
);
};
5. 只读模式
tsx
import React from 'react';
import RichTextEditor from './RichTextEditor';
const ReadOnlyEditor = ({ content }: { content: string }) => {
return (
<RichTextEditor
value={content}
disabled={true}
style={{ height: '200px' }}
/>
);
};
6. 自定义上传接口
tsx
import React, { useState } from 'react';
import RichTextEditor from './RichTextEditor';
const CustomUploadEditor = () => {
const [content, setContent] = useState('');
return (
<RichTextEditor
value={content}
onChange={setContent}
placeholder="使用自定义上传接口..."
uploadApi="/api/custom-upload"
maxLength={1000}
showCharCount={true}
style={{ height: '300px' }}
/>
);
};
高级功能
1. 智能图片粘贴
组件监听粘贴事件,自动识别剪贴板中的图片并上传:
typescript
const handlePaste = async (event: ClipboardEvent) => {
const items = event.clipboardData?.items;
if (!items) return;
for (let i = 0; i < items.length; i++) {
const item = items[i];
if (item.type.indexOf('image') !== -1) {
event.preventDefault();
const file = item.getAsFile();
if (file) await handleImageFile(file);
break;
}
}
};
2. 拖拽上传功能
支持将图片文件拖拽到编辑器区域进行上传:
typescript
const handleDrop = async (event: DragEvent) => {
event.preventDefault();
const files = event.dataTransfer?.files;
if (!files || files.length === 0) return;
const file = files[0];
if (file.type.startsWith('image/')) {
await handleImageFile(file);
}
};
3. 图片预览和编辑
使用 useRichTextTools
Hook 实现图片的预览和尺寸编辑功能:
typescript
const { mount, unmount, update } = useRichTextTools({
enablePreview: true,
enableSizeEdit: !disabled,
isReadOnly: !!disabled,
});
4. 字符计数和限制
实现HTML内容长度的实时监控和限制:
typescript
const getTextLength = (htmlContent: string): number => {
if (!htmlContent) return 0;
return htmlContent.length; // 返回完整HTML字符串长度
};
const checkWillExceedLength = (addition: number) => {
if (maxLength <= 0) return false;
const currentTextLength = getTextLength(value || '');
const newLength = currentTextLength + addition;
if (newLength > maxLength) {
showError(`添加内容后将超过最大HTML内容长度限制${maxLength}个字符`);
return true;
}
return false;
};
5. 图片缩放功能
集成 quill-blot-formatter
实现图片缩放:
typescript
import ImageResize from 'quill-blot-formatter';
// 注册图片缩放模块
Quill.register('modules/imageResize', ImageResize);
const modules = {
imageResize: {
modules: ['Resize', 'DisplaySize', 'Toolbar'],
handleStyles: {
backgroundColor: 'black',
border: 'none',
color: 'white',
},
},
};
性能优化
1. 事件监听优化
使用 useEffect
和清理函数防止内存泄漏:
typescript
useEffect(() => {
const quillElement = quillRef.current?.getEditor()?.root;
if (quillElement && !disabled) {
quillElement.addEventListener('paste', handlePaste);
quillElement.addEventListener('drop', handleDrop);
return () => {
quillElement.removeEventListener('paste', handlePaste);
quillElement.removeEventListener('drop', handleDrop);
};
}
}, [disabled, value]);
2. 图片上传状态管理
使用遮罩层显示上传状态,提升用户体验:
typescript
const [uploading, setUploading] = useState(false);
const uploadImage = async (file: File): Promise<string | null> => {
try {
setUploading(true);
// 上传逻辑...
} finally {
setUploading(false);
}
};
3. 内容大小控制
- 设置合理的
maxLength
限制 - 对于大量内容,考虑分页或懒加载
- 压缩图片尺寸,避免过大的图片文件
4. 防抖处理
对频繁的onChange事件使用防抖:
tsx
const debouncedOnChange = debounce((content: string) => {
// 处理内容变化
console.log('Content changed:', content);
}, 300);
5. 内存管理
- 组件卸载时清理事件监听器
- 避免在render中创建新的函数对象
- 合理使用React.memo和useMemo
最佳实践
1. 类型安全
使用 TypeScript 确保类型安全:
typescript
export interface RichTextEditorProps {
value?: string;
onChange?: (value: string) => void;
onBlur?: (value: string) => void;
disabled?: boolean;
placeholder?: string;
maxLength?: number;
showCharCount?: boolean;
style?: React.CSSProperties;
uploadApi?: string;
onUpload?: (file: File) => Promise<string | null>;
}
2. 错误处理
完善的错误处理机制:
typescript
const uploadImage = async (file: File) => {
try {
// 验证文件大小
if (file.size > 5 * 1024 * 1024) {
showError('图片大小不能超过5MB');
return null;
}
// 验证文件类型
const allowedTypes = ['image/jpeg', 'image/png', 'image/gif'];
if (!allowedTypes.includes(file.type)) {
showError('只支持 JPG、PNG、GIF 格式的图片');
return null;
}
// 上传处理...
} catch (error) {
showError('图片上传失败,请重试');
return null;
}
};
3. 可访问性
添加适当的ARIA标签和键盘导航支持:
typescript
// 工具栏按钮添加标题
export const addTitle = () => {
const toolbar = document.querySelector('.ql-toolbar');
if (toolbar) {
const titleConfig = {
'.ql-bold': '加粗',
'.ql-italic': '斜体',
'.ql-image': '插入图片',
// ...
};
Object.keys(titleConfig).forEach(selector => {
const button = toolbar.querySelector(selector);
if (button) {
button.title = titleConfig[selector];
}
});
}
};
常见问题解答
Q: 如何获取纯文本内容?
A: 可以通过DOM操作去除HTML标签:
tsx
const getPlainText = (htmlContent: string): string => {
const tempDiv = document.createElement('div');
tempDiv.innerHTML = htmlContent;
return tempDiv.textContent || tempDiv.innerText || '';
};
const plainText = getPlainText(content);
Q: 如何自定义图片上传接口?
A: 有两种方式自定义图片上传:
方式1:使用uploadApi属性
tsx
<RichTextEditor
uploadApi="/api/my-upload"
// ... 其他props
/>
方式2:使用onUpload自定义处理函数
tsx
const handleUpload = async (file: File): Promise<string | null> => {
const formData = new FormData();
formData.append('image', file);
try {
const response = await fetch('/api/custom-upload', {
method: 'POST',
body: formData,
headers: {
'Authorization': `Bearer ${token}`, // 可以添加认证
}
});
const result = await response.json();
return result.data.url; // 返回图片URL
} catch (error) {
console.error('Upload failed:', error);
return null;
}
};
<RichTextEditor
onUpload={handleUpload}
// ... 其他props
/>
Q: 如何实现内容的自动保存?
A: 可以使用防抖函数实现自动保存:
tsx
import { debounce } from 'lodash';
const AutoSaveEditor = () => {
const [content, setContent] = useState('');
const autoSave = debounce(async (content: string) => {
try {
await fetch('/api/save-draft', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ content }),
});
console.log('自动保存成功');
} catch (error) {
console.error('自动保存失败:', error);
}
}, 2000); // 2秒后自动保存
const handleChange = (newContent: string) => {
setContent(newContent);
autoSave(newContent);
};
return (
<RichTextEditor
value={content}
onChange={handleChange}
config={/* ... */}
/>
);
};
Q: 如何限制可用的格式选项?
A: 需要修改组件内部的formats
数组和toolbar
配置,可以创建一个自定义版本:
tsx
import React, { forwardRef, useMemo } from 'react';
import ReactQuill from 'react-quill';
// ... 其他导入
interface SimpleRichTextEditorProps extends RichTextEditorProps {
toolbar?: 'basic' | 'minimal' | 'full';
}
const SimpleRichTextEditor = forwardRef<ReactQuill, SimpleRichTextEditorProps>(
(props, ref) => {
const { toolbar = 'full', ...otherProps } = props;
const modules = useMemo(() => {
const toolbarConfigs = {
basic: [
['bold', 'italic', 'underline'],
[{ 'list': 'ordered'}, { 'list': 'bullet' }]
],
minimal: [
['bold', 'italic']
],
full: [
[{ header: [1, 2, 3, false] }],
['bold', 'italic', 'underline', 'strike'],
[{ color: [] }, { background: [] }],
[{ list: 'ordered' }, { list: 'bullet' }],
[{ align: [] }],
['image'],
['clean'],
]
};
return {
toolbar: toolbarConfigs[toolbar],
};
}, [toolbar]);
const formats = useMemo(() => {
const formatConfigs = {
basic: ['bold', 'italic', 'underline', 'list', 'bullet'],
minimal: ['bold', 'italic'],
full: ['header', 'bold', 'italic', 'underline', 'strike',
'color', 'background', 'list', 'bullet', 'align', 'image']
};
return formatConfigs[toolbar];
}, [toolbar]);
// 使用原组件的逻辑,但传入自定义的modules和formats
return <RichTextEditor {...otherProps} ref={ref} />;
}
);
// 使用示例
<SimpleRichTextEditor
toolbar="basic" // 只显示基础工具栏
value={content}
onChange={setContent}
/>
