选择和操作

order: 2

选择后进行操作，完成后清空选择，通过 rowSelection.selectedRowKeys 来控制选中项。

import { Table, Button } from 'antd';

const columns = [{
  title: '姓名',
  dataIndex: 'name',
}, {
  title: '年龄',
  dataIndex: 'age',
}, {
  title: '住址',
  dataIndex: 'address',
}];

const data = [];
for (let i = 0; i < 46; i++) {
  data.push({
    key: i,
    name: `李大嘴${i}`,
    age: 32,
    address: `西湖区湖底公园${i}号`
  });
}

const App = React.createClass({
  getInitialState() {
    return {
      selectedRowKeys: [],  // 这里配置默认勾选列
      loading: false,
    };
  },
  start() {
    this.setState({ loading: true });
    // 模拟 ajax 请求，完成后清空
    setTimeout(() => {
      this.setState({
        selectedRowKeys: [],
        loading: false,
      });
    }, 1000);
  },
  onSelectChange(selectedRowKeys) {
    console.log('selectedRowKeys changed: ', selectedRowKeys);
    this.setState({ selectedRowKeys });
  },
  render() {
    const { loading, selectedRowKeys } = this.state;
    const rowSelection = {
      selectedRowKeys,
      onChange: this.onSelectChange,
    };
    const hasSelected = selectedRowKeys.length > 0;
    return (
      <div>
        <div style={{ marginBottom: 16 }}>
           <Button type="primary" onClick={this.start}
             disabled={!hasSelected} loading={loading}>操作</Button>
           <span style={{ marginLeft: 8 }}>{hasSelected ? `选择了 ${selectedRowKeys.length} 个对象` : ''}</span>
        </div>
        <Table rowSelection={rowSelection} columns={columns} dataSource={data} />
      </div>
    );
  }
});

ReactDOM.render(<App />, mountNode);
