我想问一下,这是场景。我有多个复选框,但是我的问题是,每当我勾选一个复选框时,都会选中所有4个复选框。还有为什么checkbox的值是true还是false。这是我的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>
最佳答案
对于像我这样对redux不熟悉并 react 的人,可能会发现here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} />
