当我 ng s --aot 时收到此消息 Object is possibly 'null'.
我整个早上都在尝试解决它,有什么想法吗?错误发生在 <mdb-success *ngIf="email.valid && (email.dirty || email.touched)" class="mt-2">Email valid</mdb-success>
email.valid、dirty 等对象上。
<form class="form-inline md-form form-sm" [formGroup]="validatingForm" (submit)="update(emailInput.value)">
<input mdbInput mdbValidate type="email" class="form-control form-control-sm mr-3 w-75" placeholder="Enter user's email" aria-label="Search" formControlName="email" #emailInput required />
<button mdbBtn type="button" color="primary" mdbWavesEffect (click)="update(emailInput.value)">
<mdb-icon fas icon="search" aria-hidden="true"></mdb-icon>
</button>
<mdb-error *ngIf="email.invalid && (email.dirty || email.touched)" class="mt-2">Email invalid</mdb-error>
<mdb-success *ngIf="email.valid && (email.dirty || email.touched)" class="mt-2">Email valid</mdb-success>
</form>
ts代码:
export class UsersComponent implements OnInit {
validatingForm: FormGroup;
token: any;
userDetails: {};
hasUsers = false;
emailValue: string;
constructor(private crudService: CrudService) {}
ngOnInit() {
this.validatingForm = new FormGroup({
email: new FormControl("", Validators.email)
});
this.loginAsAdmin();
}
get email() {
return this.validatingForm.get("email");
}
