Question

我正在使用primeng日历来管理医疗约会的时间安排，我希望当我选择一个医生的日期时，他的开始和结束时间分为30分钟并显示在我的html中。这是我医生的计划数据的json呈现：[{"id":18,"planning":null,"day":"Lundi","startHour":"08:00","endHour":"17:00","isFree":true},{"id":19,"planning":null,"day":"Mardi","startHour":"09:00","endHour":"18:00","isFree":true},{"id":20,"planning":null,"day":"Mercredi","startHour":"10:00","endHour":"19:00","isFree":true},{"id":21,"planning":null,"day":"Jeudi","startHour":"11:00","endHour":"20:00","isFree":true},{"id":22,"planning":null,"day":"Vendredi","startHour":"12:00","endHour":"21:00","isFree":true},{"id":23,"planning":null,"day":"Samedi","startHour":"00:00","endHour":"00:00","isFree":false},{"id":24,"planning":null,"day":"Dimanche","startHour":"00:00","endHour":"00:00","isFree":false}]

我想在给定的一天里，我的html以30分钟为单位显示医生的小时数（开始和结束时间）。这是我在ts中检索医生的计划数据的地方：

 private loadDocdate() {

    this.httpClient.get<UserResponse>('http://127.0.0.1:8000/api/medecin/details/' + this.medecinId, this.options).subscribe((data: any) => {
      this.DocPlanning = data.medecin.planning;
      console.log(JSON.stringify(this.DocPlanning.planningLines));
    });
  }

还有我的HTML：

<ion-content fullscreen>
  <ion-text style="font-weight: bold; text-align: center">Choisissez votre Date</ion-text>
  <p-calendar [hidden]="dateValue" [(ngModel)]="dateValue" [inline]="true" [locale]="fr" dateFormat="dd-mm-yy"
  (click)="presentAlert()">
  </p-calendar>
   <div>
    <p-calendar [hidden]="!dateValue" [(ngModel)]="value" [timeOnly]="true" hourFormat="24"
     ></p-calendar>
  </div>
</ion-content>

我想要一个类似图片的显示器：

HTML的presentAlert（）函数

  presentAlert() {
    const currentDate = this.dateValue;
    const weekdays = ["Dimanche", "Lundi", "Mardi", "Mercredi", "Jeudi", "Vendredi", "Samedi"];
    this.days = weekdays[currentDate.getDay()];
    console.log(this.days);

    this.planningMedecin = this.DocPlanning.planningLines;
    this.planningMedecin.forEach(element => {
      if (element.day === this.days && element.isFree === true ) {
        this.getAlert();
        let slots = this.getTimeSlots(element.startHour, element.endHour);
        console.log(slots);

      }

      if (element.day === this.days && element.isFree !== true) {
        this.errorAlert();
      }

    });

  }
  async getAlert() {
    const alert = await this.alertCtrl.create({
      message: 'Low battery',
      subHeader: '10% of battery remaining',
      buttons: ['ok']
    });
    await alert.present();
  }

  async errorAlert() {
    const alert = await this.alertCtrl.create({
      message: 'La date que vous avez choisie est indisponible',
      subHeader: 'Nous sommes desoles',
      buttons: ['ok']
    });
    await alert.present();
  }

谢谢

您可以使用momentjs进行及时计算

参考：https://momentjs.com/

Extract time from moment js object

let timeObj = moment("08:00", [moment.ISO_8601, 'HH:mm']);
let newTimeObj = moment(timeObj).add(30, 'm').toDate();
let newTime = moment(newTimeObj).format("HH:mm");

// calculate times between 2 timeslots with 30min diff
function getTimeSlots(startTime, endTime){
    let startTimeObj = moment(startTime, [moment.ISO_8601, 'HH:mm']);
    let endTimeObj = moment(endTime, [moment.ISO_8601, 'HH:mm']);
    let appoitmentTimes = [moment(startTimeObj).format("HH:mm")]
    while(startTimeObj<endTimeObj){
        startTimeObj = moment(startTimeObj ).add(30, 'm').toDate();
        appoitmentTimes.push( moment(startTimeObj).format("HH:mm"));
    }
    return appoitmentTimes
}
let slots = getTimeSlots('08:00','17:00');
console.log(slots)
