antd Select如何中止选中

https://segmentfault.com/q/1010000018556609

通过 From 中的 getValueFromEvent 可以控制！

import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Form, Select } from "antd";

const { Option } = Select;

class RegistrationForm extends React.Component {
  render() {
    const { getFieldDecorator } = this.props.form;

    const formItemLayout = {
      labelCol: {
        xs: { span: 24 },
        sm: { span: 8 }
      },
      wrapperCol: {
        xs: { span: 24 },
        sm: { span: 16 }
      }
    };

    return (
      <Form {...formItemLayout} onSubmit={this.handleSubmit}>
        <Form.Item label="E-mail">
          {getFieldDecorator("email", {
            initialValue: ["1", "2"],
            getValueFromEvent: value => value.slice(0, 3)
          })(
            <Select
              mode="multiple"
              style={{ width: "100%" }}
              placeholder="Please select"
            >
              <Option value="1">1</Option>
              <Option value="2">2</Option>
              <Option value="3">3</Option>
              <Option value="4">4</Option>
              <Option value="5">5</Option>
            </Select>
          )}
        </Form.Item>
      </Form>
    );
  }
}

const WrappedRegistrationForm = Form.create({ name: "register" })(
  RegistrationForm
);

ReactDOM.render(
  <WrappedRegistrationForm />,
  document.getElementById("container")
);
