Moment JS（“必须显示下周的几天”）

Question

I'm working on a weather service and I need to write a code for showing the weather forecast for next week. From the server, I only have a "time" entity with "value" of next Monday like "2020-04-06T00:00:00.000+02:00".

{
    "message": "Show me the weather for next week",
    "entities": [
        {
            "value": "weather",
            "text": "weather",
            "entity": "radio_tag"
        },
        {
            "value": "play_next",
            "text": "next",
            "entity": "media_control"
        },
        {
            "value": "next",
            "text": "next",
            "entity": "next"
        },
        {
            "value": {
                "values": [
                    {
                        "value": "2020-04-06T00:00:00.000+02:00",
                        "grain": "week",
                        "type": "value"
                    }
                ],
                "value": "2020-04-06T00:00:00.000+02:00",
                "grain": "week",
                "type": "value"
            },
            "entity": "time"
        },
        {
            "value": "weather_condition",
            "entity": "sub_intent"
        }
    ],
    "intent": "weather_condition",
    "user_id": "5258",
    "language_id": "56",
    "driver": "gigaaa",
    "abort": "0",
    "extras": {
        "coordinates": {
            "lat": "44.4150804",
            "lng": "19.1290729"
        }
    },
    "conversation_messages_count": "1"
}

For example, if today is Tuesday, I must show Monday and Tuesday for next week, if today is Saturday (04.04), I must show every day from Monday (06.04) to Saturday(11.04) for next week. I am a beginner and I must use Moment JS for this.

I tried this condition if (this.conversation.payload.grain === 'week' && moment().startOf('isoWeek').isSame(this.conversation.payload.forecastTime)) but the second part of condition is not correct.

Answer 1

We take the current date and check if we aren't in the same isoweek as the data in order to filter out data rows from the current week. We then take the current date and add a week so we can check that <1 week has passed. Theoretically, as long as the timezone of the user and the returned data are the same, it should be what you need.

var valueFromData = this.conversation.payload.value;
var dateFromData = moment(valueFromData).startOf('day');
var oneWeek = moment().add(7,'d').startOf('day');
if(moment().startOf('isoweek').isBefore(dateFromData)
   && dateFromData.isBefore(oneWeek))
