它给我这样的信息,而不是显示“以小时为单位”显示了多少小时,但真正的问题是,即使日期是今天,时间应该以分钟为单位显示,但它却以小时为单位显示。
我必须根据以下条件显示时间:如果订单提前几分钟下达,则应显示“1 分钟”
,如果是几小时前,则应显示“18 小时”
它不是当前日期,它应该以“29/06/18”格式显示日期
。使用 moment.js
任何帮助都会受到赞赏。
这是我的代码:
导出类通知扩展 PureComponent {
constructor(props) {
super(props);
this.state = {
notificationsData: null,
isLoading: true
};
}
componentDidMount() {
if (notifications) {
this.setState({
notificationsData: notifications.data,
isLoading: false
});
} else {
this.setState({ isLoading: false });
}
}
renderIconBadge(icon) {
return (
<View style={styles.iconBagdeContainer}>
<Icon name={icon} size={scale(16)} />
</View>
);
}
getDateFormatted(dateTime) {
var date = moment(dateTime, "DD/MM/YYYY HH:mm").isValid() ?
moment(dateTime, "DD/MM/YYYY HH:mm")
: moment(new Date(dateTime), "DD/MM/YYYY HH:mm");
var diff = date.fromNow();
if (diff.indexOf("minute") > -1) {
return diff.substring(0, 2).trim() + " mins";
} else if (diff.indexOf("hour") > -1) {
//If it's yesterday
if(date.day() != moment().day()){
return date.format("DD/MM/YYYY");
}
return diff.substring(0, 2).trim() + " hrs";
} else {
return date.format("DD/MM/YYYY");
}
}
renderNotificationCard = ({ item }) => {
return (
<Card style={styles.notificationCardContainer}>
<View
style={{
flexDirection: "row"
}}
>
{/* <View style={{ flexDirection: "row" }}> */}
{this.renderIconBadge(item.icon)}
<View
style={{
marginLeft: scale(12)
}}
>
<Text
style={styles.location}
numberOfLines={3}
ellipsizeMode="tail"
>
{item.location}
</Text>
<View style={{ flexDirection: "row" }}>
<ClickView onPress={() => {}}>
<Text style={styles.viewBooking}>
View Booking
</Text>
</ClickView>
<Text style={styles.dateFormat}>
{this.getDateFormatted(item.dateTime)}
</Text>
</View>
</View>
{/* </View> */}
</View>
</Card>
);
};
renderNotificationList() {
const { notificationsData } = this.state;
return (
<View style={{ marginTop: scale(10), marginBottom: scale(100) }}>
{notificationsData.notification.length !== 0 ? (
<FlatList
data={this.state.notificationsData.notification}
renderItem={this.renderNotificationCard}
/>
) : (
<View
style={{
marginTop: scale(100),
alignItems: "center"
}}
>
<Image source={Images.noTaskImg} />
<Text
style={{
marginTop: scale(20),
fontSize: scale(18),
fontWeight: "600",
color: Colors.body
}}
>
No Notifications found.
</Text>
</View>
)}
</View>
);
}
render() {
const { isLoading } = this.state;
return (
<ThemeView
theme="dark"
style={styles.mainContainer}
rightButton="close"
onRightButtonPress={() => {
this.props.navigation.goBack();
}}
>
{isLoading ? (
<ProgressBar />
) : (
<View>
<View
style={{ marginTop: scale(Metrics.headerHeight) }}
>
<Text style={styles.newTasks}>New Tasks</Text>
{this.renderNotificationList()}
</View>
</View>
)}
</ThemeView>
);
}
}
JSON数据格式是这样的
{
id: "1",
icon: "water",
location:
"Your booking water",
dateTime: "2018-06-12T20:20:52.123Z"
}

最佳答案
实际上要检查差异,您可以使用 fromNow()根据结果,您可以返回您的自定义字符串。
这就是你的功能:
var getDateFormatted = function(dateTime) {
var date = moment(dateTime, "DD/MM/YYYY HH:mm").isValid() ?
moment(dateTime, "DD/MM/YYYY HH:mm")
: moment(new Date(dateTime), "DD/MM/YYYY HH:mm");
var diff = date.fromNow();
if (diff.indexOf("minute") > -1) {
return diff.substring(0, 2).trim() + " mins";
} else if (diff.indexOf("hour") > -1) {
//If it's yesterday
if(date.day() != moment().day()){
return date.format("DD/MM/YYYY");
}
return diff.substring(0, 2).trim() + " hrs";
} else {
return date.format("DD/MM/YYYY");
}
}
var getDateFormatted = function(dateTime) {
var date = moment(dateTime, "DD/MM/YYYY HH:mm").isValid() ?
moment(dateTime, "DD/MM/YYYY HH:mm") :
moment(new Date(dateTime), "DD/MM/YYYY HH:mm");
var diff = date.fromNow();
if (diff.indexOf("minutes") > -1) {
return diff.substring(0, 2).trim() + " mins";
} else if (diff.indexOf("hour") > -1) {
if (date.day() != moment().day()) {
return date.format("DD/MM/YYYY");
}
return diff.substring(0, 2).trim() + " hrs";
} else {
return date.format("DD/MM/YYYY");
}
}
var data = {
id: "1",
icon: "water",
location: "Your booking water",
dateTime: "2018-06-12T20:20:52.123Z"
};
console.log(getDateFormatted("28/06/2018 23:00"));
console.log(getDateFormatted("29/06/2018 11:50"));
console.log(getDateFormatted("28/06/2018 01:00"));
console.log(getDateFormatted(data.dateTime));
