React.js分页-无法分页数据

reactjs

请找到我尝试分页的以下代码。我有50条记录，但我不能显示10条以上的记录。而且我不知道要迭代到下10条记录直到50条记录。

render() {
  const per_page=10;
  const pages = Math.ceil(this.props.items.length / per_page);
  const current_page = 1;
  const start_offset = (current_page - 1) * per_page;
  let start_count =0;
  return (<tbody>{ this.props.items
.sort((a, b) => moment(b.order_date) - moment(a.order_date) || b.order_number - a.order_number)
.map((item, index) => {
    if (index >= start_offset && start_count < per_page) {
      start_count++;
      return <SearchResultsItem key={item.id} item={item} open={this.props.open} />;
    }
  })
}
<Pagination
  className="items-pagination pull-right"
  bsSize="medium"
  maxButton={10}
  first last next prev boundaryLinks
  item={pages}
  activePage={current_page} />
</tbody>
);
}

必须在handlePageChange（page）中传递页码，并且必须设置当前页面的页码（this.setState（{currentPage：page}）;）。

请找到工作代码：

class SearchResults extends React.Component {
 constructor(props) {
 super(props);
 this.state = {  };
}

handlePageChange(page) {
this.setState({ currentPage: page } );
}

render() {
  return (
  <div className="panel panel-primary">
    <div className="panel-heading">ORDERS LIST</div>
    <table className="table table-hover" }} >
      <thead >
        <tr>
          <th>Customer Name</th>
          <th>Assignee</th>
          <th>Status</th>
          <th>Creation Date </th>
        </tr>
      </thead>
      <SearchResultsList items={ this.props.results } open={ this.props.open 
     } 
      current_Page={ this.state.currentPage }  />
    </table>

    <Pagination id="content" className="users-pagination pull-right" 
    bsSize="medium" 
    first last  next  prev  boundaryLinks items={numPages} 
    activePage={ this.state.currentPage } onSelect={ this.handlePageChange } 
    />
   </div>
   );
  }
}
