react+ant design实现Table的增、删、改

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(
    ,
    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: '学校', dataIndex: 'schoolname', key: 'schoolname',width:'15%' },
            { title: '在校表现', dataIndex: 'description', key: 'description' ,width:'20%'},
            { title: '操作', dataIndex: '', key: 'operation', width:'32%',render: (text,record,index)=>(
                
                     
                                
                                    
                     
                    
                    
                
            ) },
        ];
        }

    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) {
                if (key === 'nid') {
                    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)

        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
                        selectedRowKeys:selectedRowKeys,
                        selectedRows:selectedRows
                })
                console.log(selectedRows,selectedRowKeys)
            },
            onSelect: (record, selected, selectedRows) => {
                //console.log( record, ` selected :${selected}`,`selectedRows:${selectedRows}`);

            }),
        }
        return (
            
); } } 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();
    }

    handleOk() {
        this.setState({
            visible: false
            });
    }
    render(){

     const {getFieldDecorator} = this.props.form;
     const formItemLayout = {
         labelCol:{span : 6},
         wrapperCol:{span: 14}
     };
     const tailFormItemLayout = {
         wrapperCol: {
             span: 14,
             offset: 8
         }
     };
        return(
            
{getFieldDecorator('name', { rules:[{ required:true,message:'请输入您的 name!' }] })( )} {getFieldDecorator('gender',{ rules:[{ required:true,message:'请输入您的 gender!' }] })( )} {getFieldDecorator('age',{ rules:[{required:true,message:'请选择您的 Age' }] })( )} {getFieldDecorator('schoolname',{ rules:[{required:true,message:'请输入您的就读学校'}] })( )} {getFieldDecorator('description',{ rules:[{required:true,message:'请输入您的在校表现'}] })( )}
) } } 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(
            
详情

姓名: {this.props.pass.name}

性别: {this.props.pass.gender}

年龄: {this.props.pass.age}

就读学校: {this.props.pass.schoolname}

在校表现: {this.props.pass.description}

) } } 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;
}
