【共享单车】—— React后台管理系统开发手记：员工管理之增删改查
前言：以下内容基于React全家桶+AntD实战课程的学习实践过程记录。最终成果github地址：https://github.com/66Web/react-antd-manager，欢迎star。
一、创建员工表单子组件
创建员工、编辑员工、员工详情、删除员工共用一个Modal弹框表单
<Modaltitle={this.state.title}
visible={this.state.isVisible}
onOk={this.handleSubmit}
onCancel={() => {
this.userForm.props.form.resetFields();
this.setState({
isVisible: false
})
}}
width={600}
{...footer}
>
<UserForm type={this.state.type} userInfo={this.state.userInfo} wrappedComponentRef={(inst) => {this.userForm = inst;}}/>
</Modal>
创建、编辑员工提交：共用handleSubmit()，判断type，通过axios.ajax()调用不同的Easy Mock数据接口请求
//创建编辑员工提交handleSubmit = () => {
let type = this.state.types;
let data = this.userForm.props.form.getFieldsValue();
axios.ajax({
url: type=='create'?'/user/add':'/user/edit',
data: {
params: data
}
}).then((res) => {
if(res.code === 0){
this.userForm.props.form.resetFields();
this.setState({
isVisible: false
})
this.requestList();
}
})
}
- 关键：
getFieldDecorator实现表单数据双向绑定
const {getFieldDecorator} = this.props.form;- 获取this.props.userInfo：【编辑员工】中设置表单默认数据、【员工信息】中显示员工信息
判断this.props.type：当type == 'detail'时，直接渲染员工信息userInfo，不再渲染Form表单
判断this.state.type：当type == 'detail'时，不显示Modal的footer按钮
let footer = {};if(this.state.type == 'detail'){
footer = {
footer: null
}
}
组件实现
//子组件：创建员工表单class UserForm extends React.Component{
getState = (state) => {
let config = {
'1':'咸鱼一条',
'2':'风华浪子',
'3':'北大才子一枚',
'4':'百度FE',
'5':'创业者'
}
return config[state];
}
render(){
let type = this.props.type;
let userInfo = this.props.userInfo || {};
const {getFieldDecorator} = this.props.form;
const formItemLayout= {
labelCol:{span: 5},
wrapperCol:{span: 19}
}
return (
<Form layout="horizontal">
<FormItem label="用户名" {...formItemLayout}>
{
type == 'detail' ? userInfo.userName :
getFieldDecorator('user_name',{
initialValue: userInfo.userName
})(
<Input type="text" placeholder="请输入用户名"/>
)
}
</FormItem>
<FormItem label="性别" {...formItemLayout}>
{
type == 'detail' ? userInfo.sex == 1 ? '男' : '女' :
getFieldDecorator('sex',{
initialValue: userInfo.sex
})(
<RadioGroup>
<Radio value={1}>男</Radio>
<Radio value={2}>女</Radio>
</RadioGroup>
)
}
</FormItem>
<FormItem label="状态" {...formItemLayout}>
{
type == 'detail' ? this.getState(userInfo.state) :
getFieldDecorator('state',{
initialValue: userInfo.state
})(
<Select>
<Option value={1}>咸鱼一条</Option>
<Option value={2}>风华浪子</Option>
<Option value={3}>北大才子一枚</Option>
<Option value={4}>百度FE</Option>
<Option value={5}>创业者</Option>
</Select>
)
}
</FormItem>
<FormItem label="生日" {...formItemLayout}>
{
type == 'detail' ? userInfo.birthday :
getFieldDecorator('birthday',{
initialValue: moment(userInfo.birthday)
})(
<DatePicker format="YYYY-MM-DD"/>
)
}
</FormItem>
<FormItem label="联系地址" {...formItemLayout}>
{
type == 'detail' ? userInfo.address :
getFieldDecorator('address',{
initialValue: userInfo.address
})(
<TextArea rows={3} placeholder="请输入联系地址"/>
)
}
</FormItem>
</Form>
)
}
}
UserForm = Form.create({})(UserForm);
二、功能区操作
- 创建员工、编辑员工、员工详情、删除员工共用一个功能操作函数handleOperate()
<Card style={{marginTop:10}} className="operate-wrap"><Button type="primary" icon="plus" onClick={() => this.handleOperate('create')}>创建员工</Button>
<Button type="primary" icon="edit" onClick={() => this.handleOperate('edit')}>编辑员工</Button>
<Button type="primary" onClick={() => this.handleOperate('detail')}>员工详情</Button>
<Button type="primary" icon="delete" onClick={() => this.handleOperate('delete')}>删除员工</Button>
</Card>
关键：传入不同的参数[type]，通过判断type的值，执行不同的操作
//功能区操作handleOperate = (type) => {
let item = this.state.selectedItem;
if(type == 'create'){
this.setState({
type,
isVisible: true,
title: '创建员工'
})
}else if(type == 'edit'){
if(!item){
Modal.info({
title: '提示',
content: '请选择一个用户'
})
return;
}
this.setState({
type,
isVisible: true,
title: '编辑员工',
userInfo: item
})
}else if(type == 'detail'){
if(!item){
Modal.info({
title: '提示',
content: '请选择一个用户'
})
return;
}
this.setState({
type,
isVisible: true,
title: '员工详情',
userInfo: item
})
}else if(type == 'delete'){
if(!item){
Modal.info({
title: '提示',
content: '请选择一个用户'
})
return;
}
let _this = this;
Modal.confirm({
title: '确认删除',
content: `是否要删除当前选中的员工${item.id}`,
onOk(){
axios.ajax({
url: '/user/delete',
data: {
params: {
id: item.id
}
}
}).then((res) => {
if(res.code === 0){
_this.setState({
isVisible: false
})
_this.requestList();
}
})
}
})
}
}
