React.js 创建一个 table 具有动态行数和 editable 列

React.js creating a table with a dynamic amount of rows with an editable column

我正在尝试创建一个与传单地图同步的 react.js table。我有这些数据并且我能够正确获取数据,但我无法正确创建 table。我能够看到 headers 因为它们是硬编码的,但我看不到行。我还有一张图片来解释代码中 console.log() 点的数据。这是代码:

/* Table React Component */
var TABLE_CONFIG = {
  sort: { column: "Zone", order: "desc" },
  columns: {
    col1: { name: "Zone", filterText: "", defaultSortOrder: "desc" },
    col2: { name: "Population", filterText: "", defaultSortOrder: "desc" }
  }
};

var Table = React.createClass({
  getInitialState: function() {
    var tabledata = [];
    var length = _.size(testJSON.zones);
    for(i = 0; i < length; i++) {

      var name = _.keys(testJSON.zones)[i];

      var population = testJSON.zones[name].population.value;
      if(name == "default") {
        population = testJSON.zones[name].population.default.value;
      }

      tabledata[i] = {name, population};
    }
    console.log(tabledata);
    return {zones: tabledata};
  },

  render: function() {
    var rows = [];
    this.state.zones.forEach(function(zone) {
        rows.push(<tr Population={zone.population} Zone={zone.name} />);
    }.bind(this));
    console.log(rows);
    return (
        <table>
            <thead>
                <tr>
                    <th>Zone</th>
                    <th>Population</th>
                </tr>
            </thead>
            <tbody>{rows}</tbody>
        </table>
      );
  }
});

在这里您可以看到完整的 console.log(tabledata) 行以及 console.log(rows)

中的第一个 object

我想看下图这样的东西。请注意,我希望 Zone 列不是 editable 输入,而是 editable:

<tr Population={zone.population} Zone={zone.name} /> 对我来说似乎不是一个有效的 React 组件。小写的 <tr> 表示这不是一个自定义组件,而是代表一个标准的 HTML table 行。 <tr> 个元素需要在其中包含 <td><th> 个元素,例如:

var rows = [];
this.state.zones.forEach(function(zone) {
    rows.push(
      <tr />
        <td><SomePopulationComponent /></td>
        <td><SomeZoneComponent /></td>
      </tr>
    );
}.bind(this));

您可以将其提取到自定义元素中:

var CustomRow = React.createClass({
    render: function() {
        return (
            <tr>
                <td>{this.props.Population}</td>
                <td>{this.props.Zone}</td>
            </tr>
        );
    }
});

// ...

var rows = [];
this.state.zones.forEach(function(zone) {
    rows.push(<CustomRow Population={zone.population} Zone={zone.name} />);
}.bind(this));

此外,不要忘记为从 map/foreach 函数内部生成的元素提供 key 属性。

我用动态行和列编辑了这个动态数据tabletable

class App extends React.Component {

    constructor(props){
        super(props);

        this.state = {
            data: [
                {'id':1,1:'',2:'Class1',3:'Class2',4:'Class3',5:'Class4',6:'Class5',7:'Class6'},
                {'id':2,1:'MONDAY',2:'1',3:'2',4:'3',5:'4',6:'5',7:'6'},
                {'id':3,1:'TUESDAY',2:'1',3:'2',4:'3',5:'4',6:'5',7:'6'},
                {'id':4,1:'WEDNESDAY',2:'1',3:'2',4:'3',5:'4',6:'5',7:'6'},
                {'id':5,1:'THURSDAY',2:'1',3:'2',4:'3',5:'4',6:'5',7:'6'},
                {'id':6,1:'FRIDAY',2:'1',3:'2',4:'3',5:'4',6:'5',7:'6'}
            ],
            errorInput:''
        };

        this.submitStepSignupForm = this.submitStepSignupForm.bind(this);
        this.appendColumn = this.appendColumn.bind(this);
        // this.editColumn = this.editColumn.bind(this);
    }

    render(){

        let tableStyle = {
            align:"center"
        };

        let list = this.state.data.map(p =>{
            return (
                <tr className="grey2" key={p.id}>
                    {Object.keys(p).filter(k => k !== 'id').map(k => {
                        return (
                            <td className="grey1" key={p.id + '' + k}>
                                <div suppressContentEditableWarning="true" contentEditable="true" value={k} onInput={this.editColumn.bind(this,{p},{k})}>
                                    {p[k]}
                                </div>
                            </td>
                        );
                    })}
                </tr>
            );
        });

        return (
            <fieldset className="step-4">
                <div className="heading">
                    <h3>Tell us about your schedule</h3>
                    <p>Dynamic Data Table by Rohan Arihant</p>
                </div>
                <div className="schedule padd-lr">
                    <table cellSpacing="3" id="mytable" style={tableStyle}>
                        <tbody>{list}</tbody>
                    </table>
                </div>
           </fieldset>
        );
    }
}
