我正在通过以下方式验证我的表单:
this.form = this.fb.group({
UnitName: [this.editUnit.UnitName, Validators.required],
Area: [this.editUnit.Area, Validators.required],
OwnerId: [this.editUnit.OwnerId],
IsWithParking: [this.editUnit.IsWithParking],
ParkingArea: [this.editUnit.ParkingArea],
});
这是要以html格式实现
<mat-card style="margin-bottom: 10px;">
<mat-card-content>
<form [formGroup]="form">
<div class="col-md-12">
<mat-form-field>
<input type="text" matInput formControlName="UnitName" placeholder="Unit Name">
<mat-error *ngIf="UnitName.invalid" style="color: red;">{{unitNameError()}}</mat-error>
</mat-form-field>
<mat-form-field>
<input type="number" matInput formControlName="Area" placeholder="Unit Area">
<mat-error *ngIf="UnitName.invalid" style="color: red;">{{areaError()}}</mat-error>
</mat-form-field>
</div>
<div class="col-md-12">
<mat-form-field>
<mat-select placeholder="Unit Owner" formControlName="OwnerId">
<mat-option *ngFor="let p of persons" [value]="p.PersonId">
{{p.FirstName}} {{p.MiddleName}} {{p.LastName}}
</mat-option>
</mat-select>
<mat-error *ngIf="OwnerId.invalid" style="color: red;">{{ownerIdError()}}</mat-error>
</mat-form-field>
</div>
<div class="col-md-12">
<mat-form-field>
<mat-select formControlName="IsWithParking" placeholder="With Parking">
<mat-option *ngFor="let y of yesNo" [value]="y.value">
{{y.name}}
</mat-option>
</mat-select>
</mat-form-field>
</div>
<div class="col-md-12">
<mat-form-field>
<input type="number" matInput placeholder="Parking Area Size" formControlName="ParkingArea">
</mat-form-field>
</div>
<button mat-raised-button class="btn btn-primary" (click)="updateUnit()" [disabled]="form.invalid">
Update Unit
</button>
<button mat-raised-button class="btn btn-warning" (click)="cancel()">
Cancel
</button>
</form>
</mat-card-content>
</mat-card>
您可以在图像中看到,但尚未执行任何操作,必填的输入字段的行和字体为默认颜色,但是对于那些没有必填属性的输入字段,其行颜色和字体为绿色。并且,当我开始填写必填字段时,行和字体的颜色也会变为绿色。有没有办法改变这种绿色?确实不符合我的红色主题色。非常感谢。

由于您正在使用Angular Material来呈现表单,因此您可能需要研究defining a custom Angular Material theme(或re-theming components on an individual basis)。
