Angular 13:删除对 api 的请求并产生一些影响
Angular 13: Delete request to api with some effects
我有一个连接到后端的前端应用程序,它运行良好,但是当我用 post 删除 div 时,它就消失了,我需要添加一些效果,所以我可以看到那个post真的消失在我的眼前了。我知道这并不难,但我是 Angular 的新手,这是我的第一个前端应用程序
删除Post方法:
deletePost1(id:number){
this.messageService.delete(id).subscribe(res => {
this.messages = this.messages.filter(item => item.id !== id);
console.log('Post deleted successfully!');
})
}
从服务中删除 post 方法:
delete(id: number) {
return this.httpClient.delete(this.apiURL + 'api/message/' + id, this.httpOptions)
.pipe(
catchError(this.errorHandler)
)
}
您可以使用 ngx-toaster 程序包显示消息
首先使用 npm 安装它:
npm install ngx-toastr
然后将其添加到您的 app.module.ts
import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';
import { AppComponent } from './app.component';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import { ToastrModule } from 'ngx-toastr';
import { ToastrService } from 'ngx-toastr';
@NgModule({
declarations: [
AppComponent,
],
imports: [
BrowserModule,
HttpClientModule,
BrowserAnimationsModule,
ToastrModule.forRoot({
tapToDismiss: false,
autoDismiss: true
})
],
providers: [
ToastrService
],
bootstrap: [AppComponent],
schemas: []
})
export class AppModule { }
然后在您的组件中像这样创建 deletePost()
:
constructor(
private toastr: ToastrService
) { }
deletePost1(id:number) {
this.messageService.delete(id).subscribe(res => {
this.messages = this.messages.filter(item => item.id !== id);
this.toastr.success("Post deleted successfully!", 'success', { timeOut: 2500 });
})
}
