• React后台管理系统-商品管理列表组件


    1.商品列表页面结构

    1. <div id="page-wrapper">
    2.              <PageTitle title="商品列表">
    3.                  <div className="page-header-right">
    4.                      <Link to="/product/save" className="btn btn-primary">
    5.                          <i className="fa fa-plus"></i>
    6.                          <span>添加商品</span>
    7.                      </Link>
    8.                  </div>
    9.              </PageTitle>
    10.              <ListSearch onSearch={(searchType, searchKeyword) => {this.onSearch(searchType, searchKeyword)}} />
    11.              <TableList tableHeads={tableHeads}>
    12.                  {
    13.                      this.state.list.map((product, index) => {
    14.                          return (
    15.                              <tr key={index}>
    16.                                  <td>{product.id}</td>
    17.                                  <td>
    18.                                      <p>{product.name}</p>
    19.                                      <p>{product.subtitle}</p>
    20.                                  </td>
    21.                                  <td>¥{product.price}</td>
    22.                                  <td>
    23.                                      <span>{product.status == 1 ? '在售' : '已下架'}</span>
    24.                                      <button className="btn btn-xs btn-warning"
    25.                                          onClick={(e) => {this.onSetProductStatus(e, product.id, product.status)}}>{product.status == 1 ? '下架' : '上架'}</button>
    26.                                  </td>
    27.                                  <td>
    28.                                      <Link className="opear" to={`/product/detail/${product.id}`}>详情</Link>
    29.                                      <Link className="opear" to={`/product/save/${product.id}`}>编辑</Link>
    30.                                  </td>
    31.                              </tr>
    32.                          );
    33.                      })
    34.                  }
    35.              </TableList>
    36.              <Pagination current={this.state.pageNum}
    37.                  total={this.state.total}
    38.                  onChange={(pageNum) => this.onPageNumChange(pageNum)}/>
    39.          </div>

    2.请求后台数据

    1. this.state = {
    2.            list : [],
    3.            pageNum : 1,
    4.            listType : 'list'
    5.        };
    6. componentDidMount(){
    7.      this.loadProductList();
    8.    }
    9.    // 加载商品列表
    10.    loadProductList(){
    11.        let listParam = {};
    12.        listParam.listType = this.state.listType;
    13.        listParam.pageNum = this.state.pageNum;
    14.        //如果是搜索的话需要传入搜索类型和搜索关键字
    15.        if(this.state.listType === 'search'){
    16.            listParam.searchType=this.state.searchType;
    17.            listParam.keyword = this.state.searchKeyword;
    18.        }
    19.        _product.getProductList(listParam).then( res => {
    20.            this.setState(res);
    21.        }, errMsg => {
    22.            this.setState({
    23.                list : []
    24.            })
    25.            _mm.errorTips(errMsg);
    26.        })
    27.    }

    3.当页码切换时,更新state里边pageNum的值

    1. //更新页码
    2.    onPageNumChange(pageNum){
    3.       //获取当前页,然后更改this.state里边的pageNum,成功以后调用this.loadProductList()方法
    4.       this.setState({
    5.          pageNum:pageNum
    6.       }, () => {
    7.           this.loadProductList();
    8.       });
    9.    }

    4.改变商品的上下架状态

    1. //改变商品的上下架状态
    2.     //1是上架,2是下架
    3.     onSetProductStatus(e,productId,currentStatus){
    4.         let newStatus = currentStatus == 1 ? 2 : 1;
    5.         // 1是上架 ,2 是下架 确认应该是说相反的
    6.         let confirmTips=currentStatus == 1 ? "确认下架该商品吗" : "确认上架该商品吗"
    7.         if(window.confirm(confirmTips)){
    8.             _product.setProductStatus(
    9.                 {
    10.                     productId:productId,
    11.                     status:newStatus
    12.                 }
    13.             ).then(res => {
    14.                 _mm.successTips(res);
    15.                 this.loadProductList();
    16.             }, errorMsg => {
    17.                 _mm.errorTips(res);
    18.  
    19.             });
    20.         }
    21.     }
