React+antd实现可编辑单元格，非官网写法，不使用可编辑行和form验证

antd3以上的写法乍一看还挺复杂，自己写了个精简版

没用EditableRow+Cell的结构，也不使用Context、高阶组件等，不使用form验证

最终效果：

class EditableCell extends React.Component {
    state = {
        editing: false
    };
    toggleEdit = () => {
        const editing = !this.state.editing
        this.setState({ editing }, () => {
            if (editing) {
                this.input.focus()
            }
        })
    };
    save = e => {
        const { record, handleSave } = this.props;
        this.toggleEdit();
        handleSave(record, e.target.value)
 
    };  // save主要处理两件事，一是切换editing状态，二是提交更新的数据
    render() {
        const { children } = this.props
        const { editing } = this.state;
        return editing ? (
            <Input defaultValue={children} ref={node=>(this.input=node)} onPressEnter={this.save} onBlur={this.save} />
        ) : (
            <span>{children}<Icon type="edit" theme='twoTone' style={{marginLeft: 10}} onClick={this.toggleEdit} />span>
            )
    }
};

最后使用的时候直接在column元素的render里面 就好啦， props一定要传处理保存修改的方法

render: (text, record) => {
    return (<EditableCell handleSave={handleModifyNote} record={record}>{text}EditableCell>) //记得传props
    }

现在这个可编辑单元格组件在鼠标失焦或者回车后，列数据会变回修改前的数据，在state里面加个text，把最后显示的 {children} 换成 {text} 就可以。

该组件也许很多页面都会使用，单独放在一个文件里再引入会优雅很多：

import React from 'react';
import {Input, Icon} from 'antd';
 
class EditableCell extends React.Component {
    state = {
        editing: false,
        text: this.props.children
    };
    toggleEdit = () => {
        const editing = !this.state.editing
        this.setState({ editing }, () => {
            if (editing) {
                this.input.focus()
            }
        })
    };
    save = e => {
        const { record, handleSave } = this.props;
        this.setState({text: e.target.value});
        this.toggleEdit();
        handleSave(record, e.target.value)
 
    };
    render() {
        const { editing, text } = this.state;
        return editing ? (
            <Input defaultValue={text} ref={node=>(this.input=node)} onPressEnter={this.save} onBlur={this.save} />
        ) : (
            <span>{text}<Icon type="edit" theme='twoTone' style={{marginLeft: 10}} onClick={this.toggleEdit} />span>
            )
    }
};
 
export default EditableCell;

引入的时候：

import { EditableCell } from '../EditableCell'

全部页面index.jsx大概是这样的

import download from '@/utils/download';
import styles from './style.less';
 
const { Option } = Select;
 
class EditableCell extends React.Component {
    state = {
        editing: false
    };
    toggleEdit = () => {
        const editing = !this.state.editing
        this.setState({ editing }, () => {
            if (editing) {
                this.input.focus()
            }
        })
    };
    save = e => {
        const { record, handleSave } = this.props;
        this.toggleEdit();
        handleSave(record, e.target.value)
 
    };
    render() {
        const { children } = this.props
        const { editing } = this.state;
        return editing ? (
            <Input defaultValue={children} ref={node=>(this.input=node)} onPressEnter={this.save} onBlur={this.save} />
        ) : (
            <span>{children}<Icon type="edit" theme='twoTone' style={{marginLeft: 10}} onClick={this.toggleEdit} />span>
            )
    }
};
