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:

复制代码
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,
          width: '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"

          {!inputVisible && (
            <Tag onClick={this.showInput} style={{ background: '#fff', borderStyle: 'dashed' }}>
              +新增
            </Tag>
          )}
        </div>
    );
  }
