react setFieldsValue

import React from "react";
import { Form, Input } from 'antd';

class TestForm extends React.Component {
  componentDidMount(){
    const { setFieldsValue } = this.props.form;
    // 这里就能实现指定表单设置value
    setTimeout(()=>{
        setFieldsValue({"username": "Tom"})
    },5000)
  }
  render() {
    const { getFieldDecorator } = this.props.form;
    return (
      <Form >
        <Form.Item>
          {getFieldDecorator('username', {})(<Input />)}
        </Form.Item>
      </Form>
    );
  }
}

export default Form.create()(TestForm)
