javascript - 表单组件名称正在 react js 中的 antd 中更新

Question

我正在使用antd表单创建任务列表，每个表单都有“提交”和“取消”按钮，每当用户创建任务时，都会生成一个新表单。我将任务数作为表单 ID。但是在更改字段时，我必须获取表单 Id，但表单 Id 正在更新任务计数值。
创建 Task.js

import React from "react";
import actions from "../redux/actions";
import store from "../redux/store";
import { Button } from 'antd';
import '../stylesheet/createTask.scss';
import {useSelector} from "react-redux";
import TaskForm from "./taskForm";
const CreateTask=()=>{
    const addTask=useSelector((state)=>{
        const {taskCount,task,templates}=state?.reducers
        return {taskCount,task,templates}
    })
    const {taskCount,task,templates}=addTask;
    const createTask=()=>{
        templates.push(<div id={`task${taskCount+1}`} key={`template${taskCount}`}><TaskForm/></div>);
        store.dispatch({type:actions.ON_ADD_TASK,payload:templates})
    }
return(
    <div className={"create-task"}>
        <span className={"task-count"}>Task {taskCount} </span>
        <Button onClick={createTask}>+</Button>
        {templates && templates.map((data)=>data)}
    </div>
)
}
export default CreateTask;

任务表单.js

import React, {useEffect, useState} from "react";
import { Form, Input, Button, Select,TimePicker,DatePicker, Space } from 'antd';
import moment from 'moment';

const layout = {
    labelCol: {
        span: 8,
    },
    wrapperCol: {

    },
};
const tailLayout = {
    wrapperCol: {
        offset: 8,
        span: 16,
    },
};

const TaskForm = () => {
    const [form] = Form.useForm();
    const taskDetails=useSelector((state)=>{
        const {taskCount,task}=state?.reducers
        return {taskCount,task}
    })
    const [fields, setFields] = useState([
        { userData: {
            task_msg:"",
            assigned_user:"",
            task_date: moment('2015-01-01', 'YYYY-MM-DD'),

    const onFinish = (fieldsValue) => {

        setFields(newFields)
        console.log("on field change" )
    }
    useEffect(()=>{

    return (

            </Form.Item>
        </Form>
    );

export default TaskForm;

Reducers.js:

import actions from "./actions";
const stateInit={
taskCount:0,
task:[],
userData:{
    task_msg: '',
    task_date: '',
    task_time: 36000,
    assigned_user: '',
    time_zone: new Date().getTimezoneOffset(),
    is_completed: 0,
},
    templates:[],
};
export default function tasks(state=stateInit, action){
    switch (action.type){
        case actions.ON_ADD_TASK:{
            return {...state,
                taskCount: state.taskCount+1,
                task:[...state.task,{userData:{...state.userData}}],
                templates:action.payload,
               };
        }
        case actions.ON_SAVE_TASK:{
            return {
                ...state,
                task:[]
            }
        }
        default:{
            return {
                ...state
            }
        }
    }

}

表单 ID 随任务计数更新。引用图片:

Answer 1

您可以使用 props 为每个任务设置不同的表单 ID。
在 Task.js 中，像这样更改 createTask:

const createTask=()=>{
templates.push(<div id={`task${taskCount+1}`} key= 
{`template${taskCount}`}><TaskForm taskId={taskCount}/></div>);
    store.dispatch({type:actions.ON_ADD_TASK,payload:templates})
}

然后在 TaskForm.js 中像这样更改您的表单:

return (
    <Form {...layout} form={form}
          initialValues={userData}
          name={`form${props.taskId}`}
          onChange={fieldsChange}
          onFinish={onFinish}>
....
</Form>
