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: '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)=>(
<span>
<Popconfirm title="删除不可恢复，你确定要删除吗?" >
<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) {
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)
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
selectedRowKeys:selectedRowKeys,
selectedRows:selectedRows
})
console.log(selectedRows,selectedRowKeys)
},
onSelect: (record, selected, selectedRows) => {
//console.log( record, ` selected :${selected}`,`selectedRows:${selectedRows}`);
},
onSelectAll: (selected, selectedRows, changeRows) => {
//console.log(selected, selectedRows, changeRows);
},
getCheckboxProps: record => ({
disabled: record.name === 'Disabled User', // Column configuration not to be checked
}),
}
return (
<div className="div_body">
<div id="div_left"></div>
<div id="div-right">
<div className="table_oftop">
<Button type="primary" icon="search" style={{float:"right",marginLeft:10}}>查询</Button>
<Input placeholder="input search text" style ={{width:300,float:"right"}}/>
<div id="add_delete">
<Button type="primary" className="selectedDelete" onClick={this.handleSelectedDelete}>删除所选</Button>
<AddUser className="add_user_btn" callback={this.appendPerson}/>
</div>
</div>
<Table columns={this.columns}
dataSource={this.state.dataSource}
className="table"
rowSelection={rowSelection}
scroll ={{y:400}}/>
</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();
}
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(
<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:[{
required:true,message:'请输入您的 name！'
}]
})(
<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">
<Option value="男">男</Option>
<Option value="女">女</Option>
</Select>
)}
</FormItem>
<FormItem {...formItemLayout} label="年龄" hasFeedback>
{getFieldDecorator('age',{
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！"/>
)}
</FormItem>
<FormItem {...formItemLayout} label="在校表现" hasFeedback>
{getFieldDecorator('description',{
rules:[{required:true,message:'请输入您的在校表现'}]
})(
<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{
