1.计算会员进度
const a = res.data.directCount（当前充值点券） / nextLevelData.map(item => item.direct_number（下一级需要点券）); //得出小数const c = 设计稿长度 /375 * Dimensions.get('window').width; （进度条长度）
会员进度： width1: 0.5 * 140 = 70 （假设）
满级时会员进度
<View style={[ styles.barActive, { '96%', }, ]} /> <View style={[ styles.process, { // transform: [{translateX: Dimensions.get('window').width < 410 ? autoWidth(243):autoWidth(255)}], //这里不用transform了 因为他不能用百分比 left:'96%' //用这个 }, ]} >

'1. VIP等级由直推好友数和朋友圈好友数直接决定，其中朋友圈好友数包含直推好友数。',
`2. 当您的直推好友数和朋友圈好友数同时满足等级要求时，您将获得专属等级标签和等级福利。`,
'3. 我们会不定期对您的朋友圈进行账户审查，若出现大批量零活跃度用户，我们有可能对您做降级处理。',
'4. 零活跃度用户判定条件主要包括：超过一个月未登录、注册满三个月但未参与任何功能版块、新注册用户7天内未登录。',
'5. 若您对您当前的VIP等级存在疑问，请您联系官方客服协助处理。',

4.刷新页面的时候 不要从 NaN 跳到数字 可以接受从0跳，但是不能接受NaN
this.state = { balance:0 } <Text>{this.state.balance?(this.state.balance / 10000).toFixed(2):'0.00'}</Text>
5.表格已经检验出条件错误，但是 还是提交了表格
解决办法，在把值赋给values.cny_price（Form提交的key）之前 ，判断它的值 ，不符合要求的话就return
6. 点击房间号，获取当前点击的name，id或者其他值（ 我这里只设置了label和roomId值） ====>
RoomList: res.data.map(item => ({
label: item.name,
roomId:item.id
}))
代码：
{RoomList ? RoomList.map((item, index) => (
<div
key={index}
onClick={() => {
this.setState({
checkRoom: index,
roomId:item.roomId // 这里可以获取，但是我用了下面的方法（这种方法不能设置默认值）
}); console.log('看看2') }} style={{ fontSize: 14, color: this.state.checkRoom === index ? '#FD8A00' : '#666', marginRight: (index + 1) % 5 === 0 ? 0 : autoWidth(20), marginBottom: 15, '15%' }}> {item.label}号 </div> )) : null}
提交表单
submit = () => { const {data,RoomList,checkRoom} = this.state this.props.history.push({pathname:'/',data:{tab:2,roomName:RoomList[checkRoom].label,name:data.name,describe:data.describe,room_category_id:data.id,roomID:RoomList[checkRoom].roomId}}) };
数据解释 ： checkRoom 设置初始值为0 和index一样，所以默认值就是第一个
RoomList[checkRoom].label 第一个房间名（默认）
RoomList[checkRoom].roomId 第一个房间id （默认）
7.传递数据展示
extra： 由于这个页面没有底部的tabs切换栏，所以页面跳转要先跳到Tabs页面 （带数据）
submit = () => {
const {data,RoomList,checkRoom} = this.state
this.props.history.push({pathname:'/',data:{tab:2,roomName:RoomList[checkRoom].label,name:data.name,describe:data.describe,room_category_id:data.id,roomID:RoomList[checkRoom].roomId}})
};
然后在Tabs页面把数据传给需要跳转的组件（注意，Tabs是多个组件组成的，tab是我设置的状态，传0就是home，以此类推·····）
正题：
this.state = {
roomTypeValue: [this.props.data&&this.props.data.room_category_id] || [],
roomNoValue: [this.props.data&&this.props.data.roomID] || [],
};
注意：由于房间号是从种类中筛选的，所以不能直接展示，需要先获取roomList，
componentDidMount() {
document.title = '预定'
if(this.props.data&&this.props.data.room_category_id){
this.getRoomList(this.props.data.room_category_id)
}
}
getRoomList(id){
HttpUtils.postForm('/api/room/category/room/list', {
id
}).then(res => {
this.setState({
RoomList:res.data.map(item=>({
label:item.name,
value:item.id,
describe:item.describe
}))
})
}).catch(err =>{
Toast.info(err)
})
}
选择器：
<Picker extra={'请选择房间类型'} title={'房间类型'} data={this.state.roomCategoryList} cols={this.state.cols} value={this.state.roomTypeValue} 这个值就是选择器选择的值，也可以当做默认值，在state的时候已经设置了 onPickerChange={this.onPickerChange2} onOk={v => { this.setState({ room_category_id: v.toString(), }) this.getRoomList(v.toString()) }} > <List.Item arrow="horizontal" onClick={this.onClick}>房间种类</List.Item> {/*<span className={'bottom-line'} />*/} </Picker>
表单提交，这里每次提交都会判断，所以应该把选择的房间种类，房间号放在前面，如果他有值，就是你选的，如果没有值，就是从前面页面传过来的
submit = () => { HttpUtils.postForm('/api/subscribe/room', { name: this.state.name, telephone: this.state.mobile, gender: this.state.gender, category: this.state.category, date: moment(this.state.date).format('YYYY-MM-DD'), user_agent: window.navigator.userAgent, start_time: moment(this.state.start_time).format('HH:mm:ss'), end_time: moment(this.state.end_time).format('HH:mm:ss'), start_date: moment(this.state.start_date).format('YYYY-MM-DD'), end_date: moment(this.state.end_date).format('YYYY-MM-DD'), room_id: this.state.room_id || (this.props.data&&this.props.data.roomID) , //每次提交都会判断 room_category_id: this.state.room_category_id || (this.props.data&&this.props.data.room_category_id) , //每次提交都会判断
}).then(res => { if (res.status === 10000) { Toast.success('提交成功 '); } else { Toast.fail(res.message); } }) };
8.从一个页面传递数据，不需要像第6点一样
传很多，只需要传一个id然后再达到的页面里直接获取数据。
9.使用组件传递数据，不需要一个一个的写，直接传 this.state就可以了
<CommonModal visible={this.state.visible} title={'确认信息'} btnText={'返回修改'} data={''}
onOk={this.state.checkType === 1 ? this.submit1 : this.submit2}
onCancel={this.onCancel} placeText={this.state.remark}
confirmInfo={this.state}/>
10.如果同时加载页面 ， 会有 存在this.props.store.App.setUser(res.data)中的数据，读取不到的情况，可以使用定时器来获取
this.timer = setTimeout(() => { this.setState({ genderValue: this.props.store.App.user ? [this.props.store.App.user.gender] : [], mobile: this.props.store.App.user.mobile_phone, name: this.props.store.App.user.name }); }, 1000);
11.如果只找data中的一个对象，那么就用 find函数，不用map ， 用Number 转换字符串为数字
this.timer = setTimeout(() => { this.setState({ genderValue: this.props.store.App.user ? [this.props.store.App.user.gender] : [], mobile: this.props.store.App.user.mobile_phone, name: this.props.store.App.user.name }); }, 1000);
12.自动填充/ 输入 / 选择 只需要一个参数就行了，
name: this.state.name, telephone: this.state.mobile, gender: this.state.genderValue[0],
改class也好改，只需要在state中设置genderValu:“” 为空字符串/空值（length为0），
className={ this.props.store.App.user.gender || this.state.genderValue ? "room-picker" : "" }
13.React 防止多次点击： 设置一个isClick值为true。if(this.state.isClick){ this.setState({isClick:false}) } 当请求有返回数据的时候，再 设置isClick为true。
14.逻辑没有写错，但是textinput框value 值就是不更新
可能需要加个定时器
componentDidMount() {
TokenAction.loadAddresses()
this.tips()
this.listener = DeviceEventEmitter.addListener('changeQRCodeAccount', (e) => {
this.timer = setTimeout(()=>{
this.setState({account: e})
},300)
})
}
