ant design 封装可填写Tag标签的input框

如图，input框可填写多个值，每个值以Tag标签的形式展示，每个标签可以新增和删除，自动过滤重复的标签。还能结合from表单，做必填值的验证。

如果没有值，提交表单的时候，会提示错误。

 话不多说，直接上代码：

这个是selfTag.js:

import {Input, Tag, Tooltip} from 'antd';
import React, { Component } from 'react';

class newTag extends Component {
  constructor(props) {
    super(props);
    this.state = {
      inputVisible: false,
      inputValue: '',
      // gorTagArr:["未处理","上线"],
      // gorTag:[
      //   {
      //     id:1,
      //     name:"未处理",
      //   },
      //   {
      //     id:2,
      //     name:"上线",
      //   }
      // ]
      gorTagArr:[],
      gorTag:[]
    };
  };

  componentDidMount() {
    const {gorTagArr}=this.props;
    const newVal=gorTagArr.map((item,index)=>({id:index,name:item}));
    this.setState({
      gorTagArr:gorTagArr,
      gorTag:newVal
    })
  };

  handleClose = removedTag => {
    const { gorTag,gorTagArr } = this.state;
    const { onOk } = this.props;
    const gorNameArr = gorTag.map(item => item.name);
    const inde = gorNameArr.indexOf(removedTag);
    this.setState({
      gorTagArr:gorTagArr.filter(i=>i!==removedTag),
      gorTag:gorTag.filter(i=>i.id!==inde),
    });
    onOk(gorTagArr.filter(i=>i!==removedTag));
  };

  saveInputRef = input => (this.input = input);

  handleInputChange = e => {
    this.setState({ inputValue: e.target.value });
  };

  showInput = () => {
    this.setState({ inputVisible: true }, () => this.input.focus());
  };

  handleInputConfirm = () => {
    const { onOk } = this.props;
    const { gorTag,gorTagArr,inputValue } = this.state;
    const gorNameArr = gorTag.map(item => item.name);
    const gorIdArr = gorTag.map(item => item.id);
    if (inputValue && gorNameArr.indexOf(inputValue) === -1) {
      const maxId = gorIdArr.length === 0 ? 0 : Math.max(...gorIdArr);
      onOk([...gorTagArr,inputValue]);
      this.setState({
        inputVisible: false,
        inputValue: '',
        gorTagArr:[...gorTagArr,inputValue],
        gorTag:[...gorTag,{id: maxId + 1, name: inputValue}]
      });
     }else{
      this.setState({
        inputVisible: false,
        inputValue: '',
      });
    }
  };


  render() {
    const {inputVisible, inputValue,gorTagArr}=this.state;
    return (
      <div
        style={{
          border: '1px solid rgb(216,216,216)',
          borderRadius: 2,
           '100%',
          padding: '5px 10px',
          marginTop: 0,
          display:"inline-block"
        }}
      >
          {gorTagArr.map((tag, index) => {
            const isLongTag = tag.length > 20;
            const tagElem = (
              <Tag key={tag} closable={index > -1} onClose={() => this.handleClose(tag)}>
                {isLongTag ? `${tag.slice(0, 20)}...` : tag}
              </Tag>
            );
            return isLongTag ? (
              <Tooltip title={tag} key={tag}>
                {tagElem}
              </Tooltip>
            ) : (
              tagElem
            );
          })}
          {inputVisible && (
            <Input
              ref={this.saveInputRef}
              type="text"
              size="small"
              style={{  78 }}
              value={inputValue}
              onChange={this.handleInputChange}
              onBlur={this.handleInputConfirm}
              onPressEnter={this.handleInputConfirm}
            />
          )}
          {!inputVisible && (
            <Tag onClick={this.showInput} style={{ background: '#fff', borderStyle: 'dashed' }}>
              +新增
            </Tag>
          )}
        </div>
    );
  }
}

export default newTag;

　　这是使用这个组件的代码：

import {Card, Col, Row, Form, Table, Button, Input, Tag,} from 'antd';
import React, { Component, Fragment } from 'react';
import { connect } from 'dva';
import SelfTag from "./selfTag";

const FormItem = Form.Item;

@connect(({ portrait,loading }) => ({
  portrait,
  listLoading: loading.effects['portrait/fetchBlockIpList'],
}))
class blockIp extends Component {
  constructor(props) {
    super(props);
    this.state = {
      page:1,
      size:15,
      text:"",
      val:{},
      flog:true,
      data:{},
      stat:""
    };
  };

  componentDidMount() {
  };

  handleTableChange = pagination => {
    const { current, pageSize } = pagination;
    const {dispatch} = this.props;
    const {val}=this.state;
    this.setState({page:current,size:pageSize})
  };

  handleSearch = (values) => {
    const { dispatch } = this.props;
    dispatch({
      type: 'portrait/fetchPortraitCommon',
      payload: {
        ...values,
      },
    });
    this.setState({val:values})
  };

  handleOk=(vale)=>{
    if(vale.length>0){
      this.searchForm.setFieldsValue({"targetUidList":vale})
    }else{
      this.searchForm.setFieldsValue({"targetUidList":undefined})
    }
  }

  // 模糊查询表单
  renderSearchForm() {
    const formItemLayout = {
      labelCol: { span: 8 },
      wrapperCol: { span: 16 },
    };
    return (
      <div style={{ marginBottom: 12 }}>
        <Form
          {...formItemLayout}
          onFinish={this.handleSearch}

              >
                <SelfTag onOk={this.handleOk} gorTagArr={[]} />
              </FormItem>
            </Col>

                <Button  onClick={() => {this.searchForm.resetFields()}} htmlType="button">

                </Button>
              </FormItem>
            </Col>
          </Row>
        </Form>
      </div>
    );
  }

  render() {
    const {
      portrait: { commonList},
      listLoading
    } = this.props;
    const {page,size,}=this.state;

    const columns = [
      {

        dataIndex: 'uid',
