redux-form中的多个复选框

Question

我想问一下,这是一个场景.我有这个多个复选框但我的问题是每当我勾选一个复选框时,所有4个复选框都被选中.而且为什么复选框的值只是真或假.这是我的复选框:

<div className="checkbox">
    <label><Field name="investor_stage" component="input" type="checkbox" value="Seed" /> Seed</label>
</div>
<div className="checkbox">
    <label><Field name="investor_stage" component="input" type="checkbox" value="Early Stages" /> Early Stages</label>
</div>
<div className="checkbox">
    <label><Field name="investor_stage" component="input" type="checkbox" value="Formative Stages" /> Formative Stages</label>
</div>
<div className="checkbox">
    <label><Field name="investor_stage" component="input" type="checkbox" value=" Later Stages" /> Later Stages</label>
</div>

对于像我这样的人来说,对于redux和反应都是新手,可能会发现这里提到的原始代码令人困惑.我修改并将其转换为ES6类.我还删除了bootstrap,验证并使其易于调试.

这是修改后的代码

import React from 'react';

class CheckboxGroup extends React.Component {

    checkboxGroup() {
        let {label, required, options, input, meta} = this.props;

        return options.map((option, index) => {
            return (
            <div className="checkbox" key={index}>
                <label>
                    <input type="checkbox"
                           name={`${input.name}[${index}]`}
                           value={option.name}
                           checked={input.value.indexOf(option.name) !== -1}
                           onChange={(event) => {
                               const newValue = [...input.value];
                               if (event.target.checked) {
                                   newValue.push(option.name);
                               } else {
                                   newValue.splice(newValue.indexOf(option.name), 1);
                               }

                               return input.onChange(newValue);
                           }}/>
                    {option.name}
                </label>
            </div>)
        });
    }

    render() {
        return (
            <div>
                {this.checkboxGroup()}
            </div>
        )
    }
}


export default CheckboxGroup;

用法:

let optionsList = [{id: 1, name: 'Optoin1'}, {id: 2, name: 'Option 2'}, {id: 3, name: 'Option 3'}]     
<Field name="roles" component={CheckboxGroup} options={optionsList} />
