一.关于react中from表单中getFieldsValue，getFieldValue，validateFields，resetFields，getFieldDecorator,initialvalue的用法
1 import React from 'react';
2 import { Card, Row, Col, Form, DatePicker, Select, Button, Checkbox, Table, Switch, message, Pagination, Input } from 'antd';
3 const { Option } = Select;
4 const FormItem = Form.Item;
5 const formItemLayout = { // label 和input宽度
6 labelCol: { span:7 },
7 wrapperCol: { span: 17 },
8 };
9 const formItemSwitch = { // label 和input宽度
10 labelCol: { span:11 },
11 wrapperCol: { span: 13 },
12 };
13
14 const AccordingConsumption = Form.create()(
15 class extends React.Component {
16 constructor() {

23 inOpLocDr:'',
24 vendor: '',
25 WaListData: [], //库存单数据
26 pageSize: 10,
27 page: 1,
28 total:0,
29 };
30 }
31
32 //清空表格内容
33 handleReset = () => {
34 this.props.form.resetFields();
35 };
36
37 searchInformation=()=>{
38 this.setState({page: 1},()=>{
39 this.getConsumptionList()
40 })
41 };
42
43 // 获取库存单列表数据
44 getConsumptionList=()=>{
45 let data = this.props.form.getFieldsValue(); //获取所以输入框的值
46 console.log('data',data);
47 let useDays = this.props.form.getFieldValue('useDays'); //获取单个输入框的值

50 let obj = JSON.parse(JSON.stringify(value));
