标签: angular typescript angular6 ng2-smart-table

我正在尝试使用组件ng2-smart-table。我确实做到了,但是在用户单击页面或列进行排序之后,我需要刷新数据,有什么方法可以捕获这些事件并刷新数据吗?

table.component.html

 <ng2-smart-table 
 [settings]="settings" 
 [source]="characters">
 </ng2-smart-table>

table.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class TableService {
  constructor(private http: HttpClient) { }
  url = 'http://localhost:4000';
  getCharacters() {
    return this
            .http
            .get(`${this.url}/characters`);
        }
}

table.interface.ts

export interface Table {
ticket: String;
title: String;
state: String;
owner: String;
age: String;
priority: String;
}

table.component.ts

  import { Component, OnInit } from '@angular/core';
  import { TableService } from './table.service';
  import { Table } from './table.interface';
  import { Observable } from 'rxjs';

  @Component({
    selector: 'app-table',
    templateUrl: './table.component.html',
    styleUrls: ['./table.component.scss']
  })
  export class TableComponent implements OnInit {

    characters: Table[];
        settings = {
          columns: {
            ticket: {
              title: 'Ticket',
              filter: false
            },
            title: {
              title: 'Title',
              filter: false
            },
            state: {
              title: 'State',
              filter: false
            },
            owner:{
              title: 'Owner',
              filter: false
            },
            age:{
              title: 'Age',
              filter: false
            },
            priority:{
              title: 'Priority',
              filter: false
            }
          },
          actions:{
            columnTitle: '',
            add: false,
            edit: false,
            delete: false
          }
    };    

        constructor(private tservice: TableService) { }

      ngOnInit() {
        this
          .tservice
          .getCharacters()
          .subscribe((data: Table[]) => {
            this.characters = data;
        });
      }
    }

parent.component.ts

import { Component, OnInit } from '@angular/core';
import { TableComponent } from '../../utils/table/table.component';

@Component({
  selector: 'app-ticket-item-list',
  templateUrl: './ticket-item-list.component.html',
  styleUrls: ['./ticket-item-list.component.scss']
})
export class TicketItemListComponent implements OnInit {

  pagination = {
    TotalItems: 100,
    CurrentPage: 1,
    PageSize: 10,
    TotalPageLinkButtons: 5,
    RowsPerPageOptions: [10, 20, 30, 50, 100]
  };

  /* Paging Component metod */
  myChanges(event) {
    this.pagination.CurrentPage = event.currentPage;
    this.pagination.TotalItems = event.totalItems;
    this.pagination.PageSize = event.pageSize;
    this.pagination.TotalPageLinkButtons = event.totalPageLinkButtons;
  }

  constructor() { }

  ngOnInit() {
  }

}

parent.component.html

<app-table></app-table>

您可以使用ng2-smart-table LocalDataSource进行过滤,设置过滤器,添加过滤器等。因此,您可以将服务结果存储在LocalDataSource对象中。在您的初始化中,类似: this.characters = new LocalDataSource(tableService.getCharacters());

以下是参考资料:https://github.com/akveo/ng2-smart-table/blob/master/src/ng2-smart-table/lib/data-source/local/local.data-source.ts

对于分页,请使用setPaging,例如

this.YourlocalDataSource.setPaging(1, 10, true);

1是页面, 10是每页的行数, true强制渲染页面
