我想从父组件更新子组件道具我的场景是我有一个组件,我正在传递一个来自 API 响应的数组列表,所以下面是我的代码
<DateRangePicker
theme={{
calendarBackground: colors.white,
selectedDayBackgroundColor: colors.kellyGreen,
selectedDayTextColor: colors.white,
todayTextColor: colors.kellyGreen,
dayTextColor: colors.intrestedButton,
dotColor: colors.kellyGreen,
selectedDotColor: colors.kellyGreen,
arrowColor: colors.kellyGreen,
monthTextColor: colors.black,
textDayFontFamily: globals.SFProTextRegular,
textMonthFontFamily: globals.SFProTextMedium,
textDayHeaderFontFamily: globals.SFProTextMedium,
textMonthFontWeight: "bold",
textDayFontSize: globals.font_11,
textMonthFontSize: globals.font_16,
textDayHeaderFontSize: globals.font_13
}}
minDate={null}
isFrom={'golfActivity'}
monthFormat={globals.selectedLocal.DATE_MMMMyyyy}
initialRange={[this.state.fromDate, this.state.toDate]}
onSuccess={(s, e) => this.setState({ fromDate: e, toDate: s })}
theme={{ markColor: colors.kellyGreen, markTextColor: colors.white
}}
underLineValue = {this.state.underLineValue}
onVisibleMonthsChange={months => { this.getChangeMonth(months) }}
/>
在上面的代码中,LineValue 是我的数组列表,它来自 API 端,当我更改月份时,我调用了 onVisibleMonthsChange 道具,我得到了新更新的月份和年份,所以我再次为此调用 API 并填写新的我更新的数组参考我的 getChangeMonth 方法如下
getChangeMonth = (months) => {
countCall = countCall + 1
if (countCall === 1) {
this.setState({isMonthChange: true})
visibleMonth = months[months.length - 1].month;
visibleYear = months[months.length - 1].year;
globals.visibleMonth= visibleMonth;
globals.visibleYear= visibleYear;
console.log("on visible month", visibleMonth);
console.log("on visible year", visibleYear);
this.callCounterAPI(visibleMonth, visibleYear);
countCall = - 1
}
}
callCounterAPI(month, year){
this.setState({ underLineValue: []})
API.getCalendarCount(this.onResponseCalendarCount, month, year,true)
}
onResponseCalendarCount = {
success: (response) => {
this.setState({underLineValue: response.data })
},
error: (err) => {
console.log("onResponseCalendarCount error-->>", err);
},
complete: () => {
}
}
export default class DateRangePicker extends Component<Props> {
state = { isFromDatePicked: false, isToDatePicked: false, markedDates: {} }
componentDidMount() {
console.log("DateRangePicker-->"+ JSON.stringify(this.props));
}
}
onResponseCalendarCount 回调我在LineValue 下填充了更新的arraylist,但是在DateRangePicker 中,当我打印它的道具时,我没有得到更新的arraylist,所以有人知道我该如何解决这个问题?欢迎您提出所有建议
