一.关于react中from表单中getFieldsValue,getFieldValue,validateFields,resetFields,getFieldDecorator,initialvalue的用法 1import React from 'react';2import { Card, Row, Col, Form, DatePicker, Select, Button, Checkbox, Table, Switch, message, Pagination, Input } from 'antd';3const { Option } =Select...
React 不存在“响应式”一说,都是单项数据流,除非自己实现。不过,如果你能在调用 setFeildValue 之后,随即触发一次视图更新,那么渲染函数里的 getFeildValue 会重新执行,把最新的值更新到视图,除非 setFeildValue有异步过程。 Class Component 强制刷新: else { form.setFeildValue("xxxx", "a"); } this.forceU...
import React from "react"; import { Form, Input, Button } from "antd"; const MyForm = () => { const [form] = Form.useForm(); const handleSubmit = () => { const fieldValue = form.getFieldValue("fieldName"); if (typeof fieldValue === "string") { console.log("This is a...
是一个用于获取表单字段值的函数。它可以用于自定义表单字段的值提取逻辑,例如对输入框的值进行处理或者从其他组件中获取值。 `getValueFromEvent`函数接受一个事件对象作为参数,并返回一个...

I was confused why getValues() was returning something different from what the form was actually rendering, and narrowed it down to only happening when isValid is destructured from formState. I need to use reset with keepDirtyValues, and it almost works, except for resetting the value returne...
在您的代码中，您可以使用'customRequest‘，文档如下：“覆盖默认的xhr行为，允许额外的定制和实现您自己...
log(data); // 这时候永远是上一次更新的数据,永远不是最新的 (因为setData是异步的更新) } // 这里是ant 的 form import {Form} from "antd"; const [form] = Form.useForm(); console.log(form.getFieldsValue()); // 为什么调用getFieldsValue永远可以拿到最新的值 // // 有个疑问 : 为什么form...
Getting value using Hooks Similarly, we can use the above procedure to get the input field value using hooks. Hooks importReact,{useState}from"react";functionApp(){const[name,setName]=useState(" ");consthandleInput=event=>{setName(event.target.value);};constlogValue=()=>{console.log(name...
