React材料ui表无法从行中获取元素

Question

我想使用材料ui库中的表做出反应:http: //www.material-ui.com/#/components/table

我显示它,它工作得很好,我试图获取与我选择的行相关联的对象,但我找不到这样做的方法,我看到了属性children或onRowSelection但我无法得到我的对象在这里是你的代码.如何获取所选行的整个对象？

import React, { PropTypes, Component } from 'react'

import Table from 'material-ui/lib/table/table';
import TableHeaderColumn from 'material-ui/lib/table/table-header-column';
import TableRow from 'material-ui/lib/table/table-row';
import TableHeader from 'material-ui/lib/table/table-header';
import TableRowColumn from 'material-ui/lib/table/table-row-column';
import TableBody from 'material-ui/lib/table/table-body';


export default class MagicTableReact extends Component {
    constructor(props) {
        super(props);
        this.state = {
            data : [{id:0,name:"joe"},{id:1,name:"john"},{id:2,name:"Brad"},{id:3,name:"Jack"},{id:4,name:"Andrew"}],
            fixedHeader: true,
            fixedFooter: true,
            stripedRows: false,
            showRowHover: true,

            deselectOnClickaway: true,
            height: '300px',
        };
    };


    _onRowSelection(e){
        console.log(e)

    }


    render() {

        return (

                                <TableRow key={i}
                                    onRowSelection={this._onRowSelection.bind(this)}>

                                    <TableRowColumn>{user.name}</TableRowColumn>
                                </TableRow>
                            )}
                        </TableBody>

更新:使用material-ui 0.15.4,传递给onRowSelection处理程序的参数已更改.请参阅@Jonathn的答案,了解正确的使用方法.

onRowSelection是<Table>不属于的财产<TableRow>.此外,它在调用(e)时不会使用事件调用处理程序,而是使用键调用它.然后,您可以使用它来查找行.像这样:

_onRowSelection(key) {
  console.log(key, this.state.data[key])
},

getInitialState() {
  return {
    data : [{id:0,name:"joe"},{id:1,name:"john"},{id:2,name:"Brad"},{id:3,name:"Jack"},{id:4,name:"Andrew"}],
    fixedHeader: true,
    fixedFooter: true,
    stripedRows: false,
    showRowHover: true,
    selectable: true,
    multiSelectable: false,
    enableSelectAll: false,
    deselectOnClickaway: true,
    height: '300px',
  };
},

render() {
  return (
    <div>
      <div className="col-sm-6">
        <h1>MagicTableReact</h1>
        <Table
          height={this.state.height}
          fixedHeader={this.state.fixedHeader}
          fixedFooter={this.state.fixedFooter}
          selectable={this.state.selectable}
          multiSelectable={this.state.multiSelectable}
          onRowSelection={this._onRowSelection}
        >
          <TableHeader>
            <TableRow>
              <TableHeaderColumn>ID</TableHeaderColumn>
              <TableHeaderColumn>Name</TableHeaderColumn>
            </TableRow>
          </TableHeader>
          <TableBody
          >
            {this.state.data.map((user, i) =>
              <TableRow key={i} value={user}>
                <TableRowColumn>{user.id}</TableRowColumn>
                <TableRowColumn>{user.name}</TableRowColumn>
              </TableRow>
            )}
          </TableBody>
        </Table>
      </div>
    </div>
  );
}

使用[Material-UI 0.15.4]

onRowSelection仅返回none,all或包含所选行的行号的数组.

使用onCellClick,也在<Table>级别,返回rowNumber,columnNumber和event.此事件包含下面的表格单元格target,您可以data-从那里引用标记等.

例:

function handleCellClick (rowNumber, columnNumber, evt) {
  console.log("activityId", evt.target.dataset.myRowIdentifier);
}

function createTableRow (content) {
  let activityId = content.shift();
  return (
    <TableRow key={activityId}>
      {content.map((columnContent, i) => {
        return (
          <TableRowColumn key={i} data-my-row-identifier={activityId} >{columnContent}</TableRowColumn>
        );
      })}
    </TableRow>
  );
}

return (
  <div>
    <Table onCellClick={handleCellClick}>
      <TableHeader displaySelectAll={false} adjustForCheckbox={false}>
      {createHeaderRow(tableHeader)}
      </TableHeader>
      <TableBody displayRowCheckbox={false}>
      {filteredTable.map(createTableRow)}
      </TableBody>
    </Table>
  </div>
);

我在StackOverflow上的第一个答案...希望它有所帮助:-)
