您可以从这两个函数开始。第一个将根据传递给页面的props动态创建您的选择选项。如果它们被映射到状态，那么选择将重新创建自己。

 createSelectItems() {
     let items = [];         
     for (let i = 0; i <= this.props.maxValue; i++) {             
          items.push(<option key={i} value={i}>{i}</option>);   
          //here I will be creating my options dynamically based on
          //what props are currently passed to the parent component
     }
     return items;
 }  

onDropdownSelected(e) {
    console.log("THE VAL", e.target.value);
    //here you will see the current selected value of the select input
}

然后你将在渲染中拥有这段代码。您将传递一个对 onChange props的函数引用，每次调用 onChange 时，所选对象将自动与该函数绑定。而不是手动编写您的选项，您只需调用 createSelectItems() 函数，该函数将根据某些约束（可以更改）构建并返回您的选项。

  <Input type="select" onChange={this.onDropdownSelected} label="Multiple Select" multiple>
       {this.createSelectItems()}
  </Input>

我的工作示例

this.countryData = [
    { value: 'USA', name: 'USA' },
    { value: 'CANADA', name: 'CANADA' }            
];

<select name="country" value={this.state.data.country}>
    {this.countryData.map((e, key) => {
        return <option key={key} value={e.value}>{e.name}</option>;
    })}
</select>

使用箭头函数绑定动态放置。

class BindDropDown extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      values: [
        { name: 'One', id: 1 },
        { name: 'Two', id: 2 },
        { name: 'Three', id: 3 },
        { name: 'four', id: 4 }
      ]
    };
  }
  render() {
    let optionTemplate = this.state.values.map(v => (
      <option value={v.id}>{v.name}</option>
    ));

    return (
      <label>
        Pick your favorite Number:
        <select value={this.state.value} onChange={this.handleChange}>
          {optionTemplate}
        </select>
      </label>
    );
  }
}

ReactDOM.render(
  <BindDropDown />,
  document.getElementById('root')
);

<div id="root">
    <!-- This element's contents will be replaced with your component. -->
</div>

// on component load, load this list of values
// or we can get this details from api call also    
const animalsList = [
{
    id: 1,
    value: 'Tiger'
}, {
    id: 2,
    value: 'Lion'
}, {
    id: 3,
    value: 'Dog'
}, {
    id: 4,
    value: 'Cat'
}
];

// generage select dropdown option list dynamically
function Options({ options }) {
    return (
        options.map(option => 
                    <option key={option.id} value={option.value}>                                   
                    {option.value}
                    </option>)
                   );
}

<select
name="animal"
className="form-control">
<Options options={animalsList} />
</select>

1 班轮将是：

import * as YourTypes from 'Constants/YourTypes';
....
<Input ...>
    {Object.keys(YourTypes).map((t,i) => <option key={i} value={t}>{t}</option>)}
</Input>

假设您将列表常量存储在一个单独的文件中（您应该这样做，除非它们是从 Web 服务下载的）：

# YourTypes.js
export const MY_TYPE_1="My Type 1"
....
