redux-form 中的多个复选框 [英] Multiple checkbox in redux-form

问题描述

我想问一下，这是场景.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.还有为什么复选框的值只是真或假.这是我的复选框:

<label><Field name="investor_stage" component="input" type="checkbox" value="Seed"/>种子
<div className="复选框"><label><Field name="investor_stage" component="input" type="checkbox" value="Early Stages"/>早期阶段

<div className="复选框"><label><Field name="investor_stage" component="input" type="checkbox" value="Formative Stages"/>形成阶段

<div className="复选框"><label><Field name="investor_stage" component="input" type="checkbox" value=" later Stages"/>后期阶段

解决方案

对于像我这样刚接触 redux 和 react 的人，可能会发现提到的原始代码 这里 令人困惑.我修改并将其转换为 ES6 类.我还删除了引导程序、验证并使其易于调试.

这是修改后的代码

从'react'导入React；class CheckboxGroup 扩展 React.Component {复选框组(){让 {label, required, options, input, meta} = this.props;返回 options.map((option, index) => {返回 (<div className="checkbox" key={index}><标签><输入类型=复选框"name={`${input.name}[${index}]`}值={option.name}选中={input.value.indexOf(option.name) !== -1}onChange={(事件)=>{const newValue = [...input.value];如果(事件.目标.检查){newValue.push(option.name);} 别的 {newValue.splice(newValue.indexOf(option.name), 1);}返回 input.onChange(newValue);}}/>{option.name}</div>)});}使成为() {返回 (<div>{this.checkboxGroup()}

)}}导出默认复选框组；

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}/>

I would like to ask, here's the scenario. I have this multiple checkbox but my problem is whenever I tick one checkbox, all of the 4 checkboxes are selected. And also why is it the value of checkbox is just true or false.Here's my checkbox:

<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>

解决方案

For people like me who are new to redux and react may find the original code mentioned here confusing. I modified and converted it to an ES6 class. I also Removed bootstrap, validation and made it easy to debug.

Here is the modified code

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;

Usage:

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