angular bootstrap datepicker通过点击输入添加样式

Question

我试图通过点击将样式应用于输入。当我按下它时，我需要在字段周围放置一个橙色框架，如果我使用焦点，那么它会被使用一会儿，然后在它移动到日历字段时消失。我用这种方法解决了问题。

<div class="input-group">
<input id="dateOfReceipt" class="form-control date calendar_input pl-4" name="dp" ngbDatepicker #dR="ngbDatepicker"
[readOnly]="true"
[minDate]="dateOfReceiptStart"
[markDisabled]="markDisabled"
[placeholder]="bus.seat.fields.jobOfferBodyFields.dateOfReceipt ?
bus.seat.fields.jobOfferBodyFields.dateOfReceipt : datePickerPlaceholder"
[(ngModel)]="bus.seat.fields.jobOfferBodyFields.dateOfReceipt"
[disabled]="!bus.isEdit" (click)="dR.toggle(); showDatepickerBorder('dateOfReceipt')"
(dateSelect)="onDateOfReceiptDateSelect($event)"
[ngClass]="{'focus-border': datePickerInputFocusBorder.dateOfReceipt}">
<div class="input-group-append">
<button class="btn calendar-button" type="button"
[disabled]="!bus.isEdit" (click)="dR.toggle(); showDatepickerBorder('dateOfReceipt')">
<mat-icon class="calendar-icon">calendar_today</mat-icon>
</button>
</div>
</div>

showDatepickerBorder(key: string) {
this.datePickerInputFocusBorder[key] = true;
}
hideDatepickerBorder(obj) {
for (let prop in obj) {
if (obj.hasOwnProperty(prop)) {
obj[prop] = false;
}
}
}
@HostListener('document:click', ['$event']) clickOutside(event) {
if (!this.eRef.nativeElement.contains(event.target)) {
this.hideDatepickerBorder(this.datePickerInputFocusBorder);
}
}

我怎样才能使它更简单?

Answer 1

您可以直接询问"dR.isOpen()"- dr是你使用的模板引用变量-并且使用[ngClass]如果你有

input.form-control:focus, .focus-border{
box-shadow: 0 0 0 .2rem rgba(255,140,0,.25);
border:orange
}

可以使用

<input class="form-control" ngbDatepicker #dR="ngbDatepicker"
[ngClass]="dR.isOpen()?'focus-border':null" ...  >
