取消选中复选框时重置输入(ReactJS + Formik)
Reset input on uncheck checkbox (ReactJS + Formik)
如果复选框被选中,我让这个组件创建一个字段,但是如果我写了一些东西然后取消选中,我该如何重置这个字段值?
const InputCheckbox = ({name, size}) => {
const [checkAmount, setCheckAmount] = useState(false);
return(
<div>
<label htmlFor={size}>
<Field type="checkbox" name={name} value={size} onClick={()=> {checkAmount === false ? setCheckAmount(true) : setCheckAmount(false)}} />
{size}
</label>
{checkAmount === false ? null : <div className="form-control-amount">
<label htmlFor={`sizeamount.${size}`}>{size}</label>
<Field className="form-control-amount" type="number" name={`sizeamount.${size}`} />
</div>}
</div>
)
}
您可以使用 Formik 的 setFieldValue
函数在取消选中复选框时重置字段。
你的组件:
const InputCheckbox = ({name, size, setFieldValue }) => {
const [checkAmount, setCheckAmount] = useState(false);
return(
<div>
<label htmlFor={size}>
<Field type="checkbox" name={name} checked={checkAmount} value={size} onClick={()=> {checkAmount === false ? setCheckAmount(true) : setCheckAmount(false); setFieldValue(`sizeamount.${size}`, '')}} />
{size}
</label>
{checkAmount === false ? null : <div className="form-control-amount">
<label htmlFor={`sizeamount.${size}`}>{size}</label>
<Field className="form-control-amount" type="number" name={`sizeamount.${size}`} />
</div>}
</div>
)
}
用法:
<Formik
initialValues={{
check: true
}}
onSubmit={(values, actions) => {
alert('Form has been submitted');
actions.setSubmitting(false);
}}
>
{({setFieldValue}) => (
<Form>
<InputCheckbox name="check" size={10} setFieldValue ={setFieldValue} />
<button type="submit">Submit</button>
</Form>
)}
</Formik>
你可以
<button
class="btn btn-primary pull-right"
type="reset"
onClick={(e) => {
e.preventDefault();
props.resetForm()
}}
>Eliminar filtros</button>
