angular - 将 ngx-pagination 实现为自定义组件

Question

我有两个组件:

list.component和pagination组件，在list组件里面我想写listing记录的逻辑，我想用ngx-pagination npm package控制给定列表的分页:

list.component.html:

<table id="example" class="patients-listing">
    <thead>
        <tr>
            <th>Member</th>
            <th>Phone</th>
            <th>Email</th>
            <th>Action</th>

        </tr>
    </thead>
    <tbody>
        <tr *ngFor="let record of data['data'] | paginate: {  id: 'server', itemsPerPage: 40, currentPage: patientsData['pagination']['current_page'], totalItems: patientsData['pagination']['total'] }">

            <td>{{record.firstname}}</td>
            <td>{{record.phone}}</td>
            <td>{{record.email}}</td>
            <td><a class="action" href="javascript:void">edit</a></td>
        </tr>
      </tbody>
  </table>
  <div class="group-pagination">
      <pagination-control id= "server" maxSize="5" (pageChange)="getUsers($event)"></pagination-control>
  </div>

list-component.ts

import { Component, OnInit, Input, AfterViewInit } from '@angular/core';
import { UserService } from '@app/services';

@Component({
  selector: 'listing',
  templateUrl: './list.component.html',
  styleUrls: ['./list.component.scss']
})
export class ListMyPatientsComponent implements OnInit, AfterViewInit {

  private currentPageNum = 1;
  private perPage = 40;
  data  = null
  constructor(private _userService: UserService) {
    this.getUsers(this.currentPageNum);
   }

  ngOnInit() {


    this._userService.currentUsersList$.subscribe((usersList)=>
    {
      if(usersList)
      {
        this.data = usersList
      }

    })
  }

  ngAfterViewInit()
  {

  }


  getCareGroup(pageNum)
  {

    this._userService.triggerCallForUsers({"page":this.currentPageNum, "perPage":this.perPage})
  }

}

到目前为止，我的服务器端分页工作得非常好。

现在我想使用 PaginationControlsDirective这样我就可以放分页模板到 list-pagination.component.html 然后我可以根据需要对此模板进行一些更改。但是当我写这个模板逻辑时list-pagination.component.html 然后将 pageChange 事件发送到 list.component 我没有得到正确的输出，我只收到分页号，例如 1 2 3... 35 > 甚至无法点击。

我在下面试过:

list-pagination.component.html:

<pagination-template id= "server" maxSize="5"  #pT="paginationApi"
(pageChange)="pageChanged()">

<div class="pagination-previous" [class.disabled]="pT.isFirstPage()">
<a *ngIf="!pT.isFirstPage()" (click)="pT.previous()"> < </a>
</div>

<div *ngFor="let page of pT.pages" [class.current]="pT.getCurrent() === page.value">
<a (click)="pT.setCurrent(page.value)" *ngIf="pT.getCurrent() !== page.value">
<span>{{ page.label }}</span>
</a>
<div *ngIf="pT.getCurrent() === page.value">
<span>{{ page.label }}</span>
</div>
</div>

<div class="pagination-next" [class.disabled]="pT.isLastPage()">
<a *ngIf="!pT.isLastPage()" (click)="pT.next()"> > </a>
</div>

</pagination-template>

list-pagination.component.ts:

import { Component, OnInit, Input, Output, EventEmitter } from '@angular/core';

@Component({
  selector: 'cg-pagination',
  templateUrl: './list-pagination.component.html',
  styleUrls: ['./list-pagination.component.scss']
})
export class PaginationComponent implements OnInit {
  @Input() id: string;
  @Input() maxSize: number;
  @Output() pageChange: EventEmitter<number> = new EventEmitter<number>();
  page = 1;

   pageChanged(event){

    this.pageChange.emit(event)
    }
  constructor() { }

  ngOnInit() {
  }


}

然后在列表组件中添加分页组件:

 <cg-pagination (pageChange)="getCareGroup($event)"></cg-pagination>

然后我只得到下面的分页输出:

需要帮助以正确的方式实现它。

谢谢!

我的问题与此类似:

Ngx-pagination does not work for custom component但我没有得到答案中解释的内容。 OP已经自己回答了。

Answer 1

您的 ngx-pagination 模板 (pagination-template) 在您的组件中，并且不与 paginationApi 通信。它应该与您在其上使用 paginate 管道的列表存在于同一 View 中。像这样:

<div *ngFor="let item of items | paginate: config">{{itemContent}}</div>

<pagination-template #p="paginationApi" [id]="config.id" 
   (pageChange)="config.currentPage = $event">

   <your-component [paginationData]="p"></your-component>

</pagination-template>

在您的组件内，扩展 paginationControls:

import { Component, Input } from '@angular/core';
import { PaginationControlsComponent, PaginationControlsDirective } from 'ngx-pagination';

@Component({
  selector: 'your-component'
  ...
})

export class YourComponent extends PaginationControlsComponent {

  @Input('paginationData') p: PaginationControlsDirective;

  constructor() {
    super()
  }

 }
