以下是一个示例代码,展示了如何在Angular DataTable中使用服务器端处理,并在上传和删除数据后刷新列表中的新数据。
import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Subject } from 'rxjs';
import { debounceTime, distinctUntilChanged } from 'rxjs/operators';
@Component({
selector: 'app-datatable',
templateUrl: './datatable.component.html',
styleUrls: ['./datatable.component.css']
})
export class DataTableComponent implements OnInit {
dtOptions: DataTables.Settings = {};
data: any[];
constructor(private http: HttpClient) { }
ngOnInit(): void {
this.dtOptions = {
pagingType: 'full_numbers',
serverSide: true,
processing: true,
ajax: (dataTablesParameters: any, callback) => {
this.http.get('http://your-server-url.com/api/data', {
params: dataTablesParameters
}).subscribe(data => {
this.data = data.data;
callback({
recordsTotal: data.recordsTotal,
recordsFiltered: data.recordsFiltered,
data: []
});
});
},
columns: [
{ data: 'id' },
{ data: 'name' },
{ data: 'email' }
]
};
}
refreshData(): void {
$('.dataTable').DataTable().ajax.reload();
}
deleteData(id: number): void {
this.http.delete('http://your-server-url.com/api/data/' + id).subscribe(() => {
this.refreshData();
});
}
uploadData(): void {
// Upload data to server
this.http.post('http://your-server-url.com/api/data', {}).subscribe(() => {
this.refreshData();
});
}
}
interface DataTablesResponse {
data: any[];
recordsTotal: number;
recordsFiltered: number;
}
ID
Name
Email
Actions
{{ item.id }}
{{ item.name }}
{{ item.email }}
import { DataTablesModule } from 'angular-datatables';
import { HttpClientModule } from '@angular/common/http';
@NgModule({
imports: [
DataTablesModule,
HttpClientModule
],
declarations: [
DataTableComponent
],
bootstrap: [DataTableComponent]
})
export class AppModule { }
这是一个基本的示例代码,用于演示在Angular DataTable中使用服务器端处理,并在上传和删除数据后刷新列表中的新数据。你需要根据你的实际需求进行适当的修改和调整。
