react+ant design实现Table的增、删、改的示例代码

本文主要是介绍react+ant design实现Table的增、删、改的示例代码，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

本人小白一名，第一次学习react ,该资料为本人原创，采用的是react+ant design的Tabled的一个小demo,暂时只实现了增加，删除单行，多行删除有Bug,查看详情，呕心沥血耗时一周完成，禁止抄袭，转载请先留言，

1、main.jsx

import React from 'react';
import ReactDom from 'react-dom';
import ExampleTable from './ExampleTable.jsx'
 
ReactDom.render(
  <ExampleTable/>,
  document.getElementById('AppRoot')
);

2、ExampleTable.jsx, 注：记住引入antd.css， 否则Table组件无法正常显示。

import React from 'react';
import { Table,Button,Input,Icon,Popconfirm,Alert } from 'antd';
import AddUser from './AddUser.jsx'
import UserDetails from './UserDetails.jsx'
 
class ExampleTable extends React.Component {
  constructor(props) {//  构造函数
    super(props);
    this.state = {
      dataSource:[
        { key: 1, nid:1, name: 'tab', gender:'男' , age: 22, schoolname: '第一中学', description: '热爱班级活动，尊敬老师'},
        { key: 2, nid:2, name: 'shift', gender:'男' , age: 22, schoolname: '第一中学', description: '热爱班级活动，尊敬老师'},
        { key: 6, nid:6, name: 'ctrl', gender:'男' , age: 22, schoolname: '第一中学', description: '热爱班级活动，尊敬老师'},
        { key: 4, nid:4, name: 'caps lock', gender:'男' , age: 22, schoolname: '第一中学', description: '热爱班级活动，尊敬老师'},
        { key: 5, nid:5, name: 'enter', gender:'女' , age: 22, schoolname: '第一中学', description: '热爱班级活动，尊敬老师'}
      ],
      index : '',
      PersonCount :0,
      selectedRowKeys:[],
      selectedRows:[],
      record : 'abc'
    };
    this.onDelete = this.onDelete.bind(this);//绑定this,声明该方法需要绑定this, 直接在onClick中调用
    this.appendPerson = this.appendPerson.bind(this);
    this.handleSelectedDelete = this.handleSelectedDelete.bind(this);
    this.columns = [
      { title: '编号', dataIndex: 'nid', key: 'nid' ,width:'8%'},
      { title: '姓名', dataIndex: 'name', key: 'name' ,width:'15%'},
      { title: '性别', dataIndex: 'gender', key: 'gender' ,width:'10%'},
      { title: '年龄', dataIndex: 'age', key: 'age',width:'15%', },//render: (text, record, index) => (Math.floor(record.age/10))*10+"多岁"},

      { title: '在校表现', dataIndex: 'description', key: 'description' ,width:'20%'},
      { title: '操作', dataIndex: '', key: 'operation', width:'32%',render: (text,record,index)=>(

                <a title="用户删除" className="mgl10"onClick={this.onDelete.bind(this,index)}>
                  <Icon type="delete"/></a>
           </Popconfirm>
          <span className="ant-divider"/>
          <UserDetails className="user_details" pass={record}/>
        </span>
      ) },
    ];
    }
 
  appendPerson(event){//得到子元素传过来的值
    let array = [];
    let count = 0;
    this.state.dataSource.forEach(function (element) {
      Object.keys(element).some(function (key) {

          count++;
          array[count] = element.nid
        }
      })
    })
    let sortData =array.sort();//对遍历得到的数组进行排序
    let MaxData = sortData[(this.state.dataSource.length)-1]//取最后一位下标的值
    event.key=MaxData+1;
    event.nid = MaxData+1;
    this.setState({
       dataSource:[...this.state.dataSource,event]
     })
 
  }
 
  onDelete(index){
      console.log(index)
      const dataSource = [...this.state.dataSource];
      dataSource.splice(index, 1);//index为获取的索引，后面的 1 是删除几行
      this.setState({ dataSource });
  }
 
  handleSelectedDelete(){
    if(this.state.selectedRowKeys.length>0){
      console.log(...this.state.selectedRowKeys)
      const dataSource = [...this.state.dataSource]
      dataSource.splice(this.state.selectedRows,this.state.selectedRows.length)
      this.setState({ dataSource });
    }
    else{
 
    }
  }
 
  render() {
    //联动选择框
    const rowSelection = {
      onChange: (selectedRowKeys, selectedRows) => {
        this.setState({//将选中的id和对象存入state

           <AddUser className="add_user_btn" callback={this.appendPerson}/>
           </div>
         </div>
        <Table columns={this.columns}

      </div>
      </div>
    );
  }

module.exports = ExampleTable;

3、AddUser.jsx

import React from 'react';
import {Form,Input,Button,Select,Modal} from 'antd'
const FormItem = Form.Item;
const Option = Select.Option;
 
class AddUser extends React.Component{//在es6中定义一个AddUser类
   constructor(props){//构造函数
     super(props);
     this.state = {
       visible:false
     };
     this.handleAdd = this.handleAdd.bind(this);
     this.handleSubmit = this.handleSubmit.bind(this);
     this.handleOk = this.handleOk.bind(this)
     this.handleClear = this.handleClear.bind(this)
   }
  handleAdd() {
    this.setState({
      visible: true
    });
  }
  handleSubmit(e){//提交表单
    e.preventDefault();
     this.props.form.validateFieldsAndScroll((err,values)=>{
       if(!err){
         //console.log('接收的值：',values);
         this.setState({
           visible:false
         })
         this.props.form.resetFields();//清空提交的表单
         //当值传递到父元素后，通过回调函数触发appendPerson方法将参数values带到父元素
         this.props.callback(values);
       }
     })
  }
 
  handleClear(){
    this.props.form.resetFields();
  }

  }
  render(){
 
   const {getFieldDecorator} = this.props.form;
   const formItemLayout = {
     labelCol:{span : 6},
     wrapperCol:{span: 14}
   };
   const tailFormItemLayout = {
     wrapperCol: {
       span: 14,
       offset: 8
     }
   };
    return(
      <div>
        <Button type="primary" onClick={this.handleAdd}>添加用户</Button>
      <Modal title="新建用户" visible={this.state.visible} onCancel={this.handleOk} onOk={this.handleOk}>
        <Form onSubmit={this.handleSubmit}>
          <FormItem {...formItemLayout} label = "用户名" hasFeedback>
            {getFieldDecorator('name', {
              rules:[{

              }]
            })(
              <Input placeholder="请输入您的用户名！"/>
            )}
            </FormItem>
          <FormItem {...formItemLayout} label="性别" hasFeedback>
            {getFieldDecorator('gender',{
              rules:[{
                required:true,message:'请输入您的 gender！'
              }]
            })(
              <Select placeholder="请选择您的性别">

              rules:[{required:true,message:'请选择您的 Age'
              }]
            })(
              <Select placeholder="请选择你您的年龄">
                  <Option value="26">26</Option>
                  <Option value="27">27</Option>
                  <Option value="28">28</Option>
              </Select>
            )}
          </FormItem>
          <FormItem {...formItemLayout} label="就读学校" hasFeedback>
            {getFieldDecorator('schoolname',{
              rules:[{required:true,message:'请输入您的就读学校'}]
            })(
              <Input placeholder="请输入您的就读学校！"/>
            )}

            })(
              <Input type="textarea" rows={3} placeholder="请输入您的在校表现!"/>
            )}
          </FormItem>
          <FormItem {...tailFormItemLayout} style={{padding:10}}>
            <Button type="primary" htmlType="submit" size="large">提交</Button>
            <Button type="primary" size="large" onClick={this.handleClear}>重置</Button>
          </FormItem>
        </Form>
      </Modal>
      </div>
    )
  }
}
AddUser = Form.create()(AddUser); //解决了getFieldDecorator无法定义;
 
export default AddUser;

4、UserDetails.jsx

import React from 'react'
import {Modal,Button} from 'antd'
/*
 
 */
class UserDetails extends React.Component{
  constructor(props){
    super(props);
    this.state={
      visible:false
    }
    this.handlePopup = this.handlePopup.bind(this);
    this.handleOkOrCancel = this.handleOkOrCancel.bind(this);
  }
  handlePopup() {
    this.setState({
      visible: true
    });
  }
  handleOkOrCancel(){
    this.setState({
      visible: false
    });
  }
 
  render(){
    return(
      <div>
        <a onClick={this.handlePopup}>详情</a>
        <Modal title={this.props.pass.name} visible={this.state.visible}
            onOk=  {this.handleOkOrCancel} onCancel={this.handleOkOrCancel}>
          <p>姓名：  {this.props.pass.name}</p>
          <p>性别：  {this.props.pass.gender}</p>
          <p>年龄：   {this.props.pass.age}</p>
          <p>就读学校：  {this.props.pass.schoolname}</p>
          <p>在校表现：  {this.props.pass.description}</p>
        </Modal>
      </div>
    )
  }
 
}
 
export default UserDetails;

5、ExampleStyle.css

#div-right{
  width:80%;
  height:400px;
  text-Align:center;
  margin: 0 auto;
}
.div_body{
  margin-top: 0.5%;
}
.table_oftop{
  padding: 10px;
}
.selectedDelete{
  float: left;
  margin-left: 35%;
}
.add_user_btn{
  margin-left: auto;
}
.user_details{
  float: right;
}
