我尝试做简单的表单渲染,但我总是遇到此错误
Unknown props `input`, `meta` on <input> tag.
之前我已经研究过这个问题,并且除了github讨论之外没有找到任何东西,它实际上会抛出4到5个不同的实现,如何在没有达成共识的情况下完成,我也遵循了v6文档&#39;以这种方式实施,但无济于事。有什么建议吗?
我正在使用v6.2.0,这是我发布此内容时的最新版本。
我直接从这里的示例http://redux-form.com/6.0.0-alpha.15/examples/syncValidation/复制粘贴,仍然会出错。 (我在下面附上了他们的代码)
import React from 'react'
import { Field, reduxForm } from 'redux-form'
const validate = values => {
const errors = {}
if (!values.username) {
errors.username = 'Required'
} else if (values.username.length > 15) {
errors.username = 'Must be 15 characters or less'
}
if (!values.email) {
errors.email = 'Required'
} else if (!/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i.test(values.email)) {
errors.email = 'Invalid email address'
}
if (!values.age) {
errors.age = 'Required'
} else if (isNaN(Number(values.age))) {
errors.age = 'Must be a number'
} else if (Number(values.age) < 18) {
errors.age = 'Sorry, you must be at least 18 years old'
}
return errors
}
const renderField = props => (
<div>
<label>{props.placeholder}</label>
<div>
<input {...props}/>
{props.touched && props.error && <span>{props.error}</span>}
</div>
</div>
)
const SyncValidationForm = (props) => {
const { handleSubmit, pristine, reset, submitting } = props
return (
<form onSubmit={handleSubmit}>
<Field name="username" type="text" component={renderField} placeholder="Username"/>
<Field name="email" type="email" component={renderField} placeholder="Email"/>
<Field name="age" type="number" component={renderField} placeholder="Age"/>
<div>
<button type="submit" disabled={submitting}>Submit</button>
<button type="button" disabled={pristine || submitting} onClick={reset}>Clear Values</button>
</div>
</form>
)
}
export default reduxForm({
form: 'syncValidation', // a unique identifier for this form
validate // <--- validation function given to redux-form
})(SyncValidationForm)
