作者最近新的平台项目是需要用react的,和vue区别还是比较大的,这里记录下踩坑和使用经验。
框架:antd

不知道是react本身编译规则严苛,还是公司的pipline设定,代码里面编译的时候不允许有未使用的变量,不允许使用未导入的组件
举个例子,如果使用了分页,但是没有导入Pagination,编译报错
- import {Button, Modal, Layout, messag, Space, Table, Cascader, Input} from 'antd';
-
-
- <Pagination onChange={this.onPageChange} total={this.state.totalSize}/>
如果标识了参数但是没有用,编译报错
- onPageChange = (page, size) => {
- this.setState({page: page});
- this.loadList();
- };
这是很坑的,设置变量值之后居然没有变,是有延迟的,所以当设置完之后需要间隔一下再去使用,作者就出现了点击第二页显示第一页
- onPageChange = (page, size) => {
- this.setState({size: size});
- this.setState({page: page});
- setTimeout(() => {
- this.loadList();
- }, 5);
- };
根据官网显示,列表数量超过50才会显示数量选择器,除非你显式指定,但是问题是有必要组件自己做这种判断吗,看的人一头雾水
这里就是上传组件里面嵌套了一个按钮,不知道为什么选中文件之后会多次触发fileChange
,fileChange调用upload然后后面两次的文件还是空的,然后就告警两次
- <Upload
- loading={this.state.uploadLoading}
- id='modify-excel-input'
- className='modify-excel-input'
- accept='.xls,.xlsx'
- action={getUploadFileUrl()}
- beforeUpload={this.checkFile}
- onRemove={this.deleteFile}
- onChange={this.fileChange}
- maxCount={1}
- >
- <Button
- loading={this.state.uploadLoading}
- icon={<UploadOutlined/>}>上传</Button>
- </Upload>
-
-
- upload = () => {
- console.log('RetrySelect upload');
- if (this.state.fileList == null || this.state.fileList.length <= 0
- || this.state.fileList[0].response == null || this.state.fileList[0].response.length <= 0) {
- message.error("请上传文件");
- return;
- }
- }
所以作者就在fileChange里面加了判断看文件是否为空
- fileChange = ({fileList: newFileList}) => {
- if (newFileList == null || newFileList.length <= 0
- || newFileList[0].response == null || newFileList[0].response.length <= 0) {
- return;
- }
- console.log("文件列表: ", newFileList);
- this.state.fileList = newFileList;
- this.upload();
- }
输入框、选择框之类的组件需要和本地变量进行绑定,但是他就不像vue简单的设置v-model就可以,他需要识别变更方法
还必须bind(this),不然绑定本地变量的话根本没法写进输入框,官网也没什么说法,chatGpt也不知道,让人一头雾水
- <Input
- maxLength={100}
- value={this.state.subject}
- style={{width: '350px'}}
- onChange={this.changeSubject.bind(this)}
- placeholder="请输入"/>
-
- changeSubject = (event) => {
- this.setState({subject: event.target.value});
- };
这里再介绍一些基础使用
如果表格数据不固定,就可以后端返回列名
- const processedColumns = resData.columns.map(column => {
- return {
- ...column,
- dataIndex: column.dataIndex,
- title: column.title,
- width: '200px',
- };
- });
-
-
- this.setState({columns: processedColumns})
-
-
- <Table
- columns={this.state.columns}
- dataSource={this.state.list}
- bordered
- scroll={{x: 1500, y: 'calc(100vh - 350px)'}}
- pagination={false}
- />
超过一定长度展示省略号,悬浮展示所有
- {
- title: 'response',
- dataIndex: 'response',
- width: '180px',
- render: (text) => {
- return <Tooltip placement="top" title={text}>
- <div style={{
- width: 150,
- overflow: "hidden",
- textOverflow: "ellipsis",
- whiteSpace: "nowrap"
- }}>{text}</div>
- </Tooltip>
-
- }
- },
原始页面把参数直接缀在路径后面就可以,如果是很多参数可以用json转字符串,到目标页面进行解析
- const w = window.open('about:blank');
- w.location.href = '#/detail/' + record.id;
目标页面通过匹配参数拿到
- constructor(props) {
- super(props);
- this.state = {
- loadingExecute: false,
- id: props.match.params.id,
参数的名字是由配置url页面决定的
- {
- path: '/detail/:id?',
- name: 'detail',
- pageId: '1010',
- authPass: true,
- },
他的弹窗使用visible属性判断是否展示的,在render里面定义号,然后通过更新本地变量进行展示隐藏
- <Modal visible={this.state.executeVisible} onOk={this.goExecute.bind(this)}
- onCancel={this.handleCancel.bind(this)}
- footer={[
- <Button key="submit" type="primary" onClick={this.goExecute.bind(this)}>
- 确认
- </Button>,
- <Button key="back" onClick={this.handleCancel.bind(this)}>
- 取消
- </Button>
- ]}>
- <div style={{marginTop: '20px'}}>
- <span style={{width: '80px', marginRight: '10px'}}>工单</span>
- <Input
- maxLength={100}
- value={this.state.woCode}
- style={{width: '350px', marginRight: '20px'}}
- onChange={this.changeWoCode.bind(this)}
- placeholder="请输入"/>
- </div>
- <div style={{marginTop: '20px'}}>
- <span style={{width: '80px', marginRight: '10px'}}>主题</span>
- <Input
- maxLength={100}
- value={this.state.subject}
- style={{width: '350px'}}
- onChange={this.changeSubject.bind(this)}
- placeholder="请输入"/>
- </div>
- </Modal>
主要是获取域名和cokkie
- const cookie = document.cookie.split(';')
-
- const host = document.domain.toLowerCase()
不同的前端使用起来区别挺大的,作者感觉还是vue好用一些,不过react好像更加国际化一些,公司整体还是偏向用react。
