Angular 8 Metronic 绑定未更新

问题描述

我使用 Angular 8 Metronic 开始了一个项目.

我有一个带有表单的组件.我希望微调器在提交点击时出现并在 API 响应时消失.这是组件代码的一部分:

@Component({选择器:'更改密码'，templateUrl: './change-password.component.html',styleUrls: ['./change-password.component.scss'],})导出类 ChangePasswordComponent 实现 OnInit、OnDestroy {isLoading: boolean = false;...提交() {this.isLoading = true;this.utilisateurService.changePassword(changePasswordData).pipe(finalize(() => this.isLoading = false)).subscribe(() => {});}...}

当我点击提交按钮时，isLoading 属性更新为 true 并出现微调器.当 finalize() 执行时，isLoading 属性更新为 false 但 Spinner 不会消失...

我不明白.

我尝试使用 NgZone 但同样的问题.

有什么想法吗?

编辑

我尝试过点击订阅.还是一样的问题.问题仅适用于渲染.如果我再次单击提交按钮，isLoading 属性为 false，正如预期的那样.但微调器仍在运行.

解决方案

可以解决这个问题，在app.component.ts文件中changeDetection配置设置为.

I started a project with Angular 8 Metronic.

I have a component with a form. I want spinner appears on submit click and disappear on API response.Here is a part of the component code :

@Component({
	selector: 'change-password',
	templateUrl: './change-password.component.html',
	styleUrls: ['./change-password.component.scss'],
})
export class ChangePasswordComponent implements OnInit, OnDestroy {

	isLoading: boolean = false;
	...
	submit() {

		this.isLoading = true;

		this.utilisateurService
			.changePassword(changePasswordData).pipe(finalize(() => this.isLoading = false))
			.subscribe(() => {});
	}
        ...
}

<form class="kt-form" [formGroup]="changePasswordForm" autocomplete="off">
        ...
	<div class="kt-login__actions">
		<button (click)="submit()"
		[ngClass]="{'kt-spinner kt-spinner--right kt-spinner--md kt-spinner--light': isLoading}">
			Submit
		</button>
	</div>
</form>

When I click on submit button, isLoading property is updated to true and spinner appears.When finalize() executes, isLoading property is updated to false but spinner do not disappear...

I don't understand.

I tried to use NgZone but same problem.

Any idea ?

Edit

I tried with tap and subscribe. Still the same problem.Problem is only for rendering.If I click on submit button again, isLoading property is false, as expected. But spinner still running.

解决方案

You can resolve this problem, in the app.component.ts file changeDetection configuration set to Default.
