this.datePicker设置两次：

1. jQuery('#event_start')
2. jQuery('#event_end')
   我建议您像这样重构代码：

const datePickerConfig = {
    autoclose: true,
    orientation: 'left bottom',
};

this.startDatePicker = document.querySelector('#event_start').datepicker(datePickerConfig);
this.endDatePicker = document.querySelector('#event_end').datepicker(datePickerConfig);

为了有效地帮助您，请告诉您正在使用哪个日期选取器库。

您可以从Angular Bootstrap 中使用ngb-datepicker。
按以下方式修改组件.ts，

now: Date = new Date();
minDate: any;
maxDate: any;

//If you want to disable past dates from current date, you can set mindate to current date.

this.minDate = { year: this.now.getFullYear(), month: this.now.getMonth() + 1, day: this.now.getDate() };

//If you want to show upcoming 50 years in dropdown, you can set maxdate like,

this.maxDate = { year: this.now.getFullYear() + 50, month: 1, day: 1 };

在您的component.html中，

<input id="event" name="event" [(ngModel)]="model" (click)="event.toggle()" #event="ngbDatepicker" [min]="minDate" [max]="maxDate" ngbDatepicker>

多亏了@ kishoreae，我找到了前进的道路。
我正在使用Angular 6和ng-Bootstrap。
我要求将最小日期设置为今天，最大日期将为从今天起1年。

日期组件.组件.ts

import {NgbDateStruct} from '@ng-bootstrap/ng-bootstrap';

最小日期逻辑

now: Date=new Date();

  minDate :NgbDateStruct = { year: this.now.getFullYear(), month: this.now.getMonth() + 1, day: this.now.getDate() };

最大日期逻辑

maxDate :NgbDateStruct={year: this.now.getFullYear()+1, month: this.now.getMonth()+1, day: this.now.getDate()}

日期组件.组件.html

<form class="form-inline">
    <div class="form-group">
          <div class="input-group">
            <input class="form-control restricttextboxsize removeBorderright" placeholder="{{Initialdate | date:'dd/MM/yyyy'}}" name="dpStartDate"
              [(ngModel)]="modelStartDate" ngbDatepicker #dStartDate="ngbDatepicker" [minDate]="minDate" [maxDate]="maxDate">
            <div class="input-group-append dateborder">
              <img src={{calendarImageinstance.standardimage}} class="pqestartdate grayscale" (click)="dStartDate.toggle()" />
            </div>
          </div>
        </div>
      </form>
