我正在使用angular4进行分页。我使用ngx分页来实现分页过程。我需要根据用户选择的类型应用分页。如果用户选择类别，我需要用分页显示类别数据，默认情况下在页面上加载，我需要用分页显示所有数据。这里我面临着问题，因为分页仅适用于类别数据。下面是我的代码:

import { Component, OnInit } from '@angular/core';
import {Http,Response,Headers, RequestOptions} from '@angular/http';
import { Router} from '@angular/router';
import * as _ from "lodash";
import { PaginationService } from '../../pagination.service';
import { WooApiService } from 'ng2woo';
import {SearchFilterPipe} from '../../search-filter.pipe'
@Component({
  selector: 'app-products',
  templateUrl: './products.component.html',
  styleUrls: ['./products.component.css']
})
export class ProductsComponent implements OnInit {
visible:boolean=false;
visibleCategory:boolean=true;
  public productsList=[];
public categories=[];
public categoryList=[];
catId:Number;
    public objArray: Array<string> = ["Albania", "Andorra", "Armenia", "Austria", "Azerbaijan"];
total:any;  
    currentPage:Number;
constructor(private http:Http,private router:Router,private woo: WooApiService) { 
    this.getCategories();
  }
createAuthorizationHeader(headers: Headers) {
    headers.append('Authorization', 'Basic ' +
      btoa('ck_543700d9f8c08268d75d3efefb302df4fad70a8f:cs_f1514261bbe154d662eb5053880d40518367c901')); 
    headers.append("Content-Type", "application/json");
  }   
    getData(){

     let headers = new Headers();
     this.createAuthorizationHeader(headers);
return this.http.get("https://www.colourssoftware.com/wordpress/wp-json/wc/v2/products?page=1&per_page=10",{
        headers:headers
        })
      .subscribe(data => { 
        const products=data.json();
          console.log(data.headers);

     this.total = data.headers.get('X-WP-TotalPages');
    console.log("Pages ",this.total);

           for( var i=1;i<=this.total;i++){
    console.log("hello "+this.total);
    this.getProducts(i);
    }   
    },
err => {
    console.log("Error!: ",err);
}
        );
       

    }   
getProducts(i){ 
    this.visibleCategory=true;
    this.visible=false;
    this.currentPage=i;
    console.log("cpage "+this.currentPage);
    let headers = new Headers();
    this.createAuthorizationHeader(headers);
return this.http.get("https://www.colourssoftware.com/wordpress/wp-json/wc/v2/products?per_page=10&page="+this.currentPage,{
        headers:headers
        })
      .subscribe(data => { 
          const products = data.json();
for(var k=0;k<products.length;k++){
    this.productsList.push(products[k]);
    }
          console.log("hello"+JSON.stringify(this.productsList));
        },
err => {
    console.log("Error!: ",err);
}
        ); 

 } 
       getCategories(){
   console.log('categories');
    let headers=new Headers();
    this.createAuthorizationHeader(headers);
   return this.http.get('https://www.colourssoftware.com/wordpress/wp-json/wc/v2/products/categories',{
       headers:headers
       })
     .subscribe(data => { 
       const category=data.json();
       console.log(category);
         this.categories=category;
         console.log(JSON.stringify(this.categories));
       },
err => {
   console.log("Error!: ",err);
}
       );
   }
getCatProducts(id,count){
if(count<=10){
    this.visible=true;
    this.visibleCategory=false;
    this.catId=id;
    console.log("id "+this.catId);
    let headers=new Headers();
    this.createAuthorizationHeader(headers);
   return this.http.get('https://www.colourssoftware.com/wordpress/wp-json/wc/v2/products?category='+this.catId,{
       headers:headers
       })
     .subscribe(data => { 
       const items=data.json();
       console.log(items.length);
         this.categoryList=items;
         console.log(JSON.stringify(this.categoryList.length));
       },
err => {
   console.log("Error!: ",err);
}
       ); 
    }
}
 
product(value){
    this.router.navigate(['productdetails',value]);
}

  ngOnInit() {
      this.getData();  
  }

如何在 Angular4 中实现多分页？

最佳答案

您必须在每个分页项目上添加 id

 <pagination-controls id="pagination1"....>  </pagination-controls>
 <pagination-controls id="pagination2"....>  </pagination-controls>

您还必须添加列表页面的 ID，如下所示:

<some-element *ngFor="let item of collection | paginate: { id: 'pagination1',
                                                      itemsPerPage: pageSize,
                                                      currentPage: p,
                                                      totalItems: total }">...</some-element>
