我有一个组件,当一个人的名字发生变化时,我想通过发出一个事件来更新它。我的问题是代码由于错误而无法编译。这是我的代码
应用窗体组件
@Output() nameChange = new EventEmitter();
closeAccordion(isComplete: string, accordionToClose: string, accordion: NgbAccordion) {
if (accordionToClose === 'personal-details-panel') {
this.applicationStatusFlags.personalDetailsStatus = (isComplete === 'true');
this.nameChange.emit({ personId: this.personId });
}
}
ApplicationFormComponent.html
<name-display
[personId]="personId"
[placeHolderText]="'Hello'"
(nameChange)="update($event)">
</name-display>
名称DisplayComponent
import { Component, Input, OnChanges, SimpleChanges } from '@angular/core';
import { PersonService } from "../../../service/person.service";
@Component({
selector: 'name-display',
templateUrl: './NameDisplay.component.html',
providers: [PersonService]
})
export class NameDisplayComponent implements OnChanges {
constructor(private readonly personService: PersonService) { }
@Input() personId;
@Input() placeHolderText: string = "";
forename: string = "";
ngOnChanges(changes: SimpleChanges): void {
if (changes["personId"]) {
this.personService.getPersonDetails(this.personId).subscribe((res: IPersonDetails) => {
this.forename = res.forenames;
});
}
};
update(personId: number) {
alert("update name");
this.personService.getPersonDetails(personId).subscribe((res: IPersonDetails) => {
this.forename = res.forenames;
});
}
}
我的问题基本上是当我将 angular cli 与命令 ng server --aot 一起使用时,由于此错误而无法编译:
ERROR in src\app\component\ApplicationForm\ApplicationForm.component.html(42,9): : Property 'update' does not exist on type 'ApplicationFormComponent'.
我编写了一个类似的组件,它使用了一个没有这个问题的事件发射器,所以我不知道如何修复这个错误。
有任何想法吗?
