Projek yang saya sedang kerjakan baru-baru ini menggunakan Antd dan reac-redux, dan terdapat sebutan borang di dalamnya. Keperluan saya ialah melakukan pengesahan bahagian hadapan apabila pengguna memasukkan atribut getFieldDecorator
;当用户提交表单之后,将后端返回的错误信息对应到表单中,这里使用了Antd提供的自定义校验,即FormItem
的help
和validateStatus
yang disediakan oleh Antd digunakan di sini.
Tetapi saya mendapati bahawa apabila menggunakan pengesahan tersuai, getFieldDecorator
就不在起作用了。那如果想使用getFieldDecorator
pengesahan dan ingin menggunakan pengesahan tersuai apabila bahagian belakang mengembalikan data, bagaimanakah saya harus menanganinya?
Terima kasih semua terlebih dahulu.
Coretan kod yang dilampirkan:
submitLogin = (e) => {
e.preventDefault();
// 前端验证
this.props.form.validateFields((err, values) => {
if (!err) {
// 前端验证无误,向后端提交
this.props.submitLoginForm(values);
}
});
};
render() {
const { getFieldDecorator } = this.props.form;
// 后端返回结果
const access = this.props.loginState.results;
const rulesGenerate = {
email: getFieldDecorator('email', {
rules: [
{ required: true, message: '请填写邮箱' },
{ type: 'email', message: '邮箱格式不对' },
]
})
};
// 服务器返回的数据是否有error
const errors = access.error?access.error:false;
return (
<Form onSubmit={this.submitLogin} className="login-form">
<FormItem
className="login-form__item"
validateStatus={errors&&errors.email?'error':''}
help={errors&&errors.email?errors.email:''}
>
{rulesGenerate.email(
<Input addonBefore={<Icon fontSize="20" type="user" />} placeholder="用户名 / ID / 手机号" />
)}
</FormItem>
</Form>
);
// 传送state到UI组件的props
const mapStateToProps = (state) => {
return {
loginState: state.loginReducer
}
}
// 派发事件
const mapDispatchToProps = (dispatch) => {
return {
submitLoginForm: (values) => {
dispatch(loginProcessing(values))
}
}
}
// 连接UI组件
const ShowForm = connect( mapStateToProps,mapDispatchToProps )(Login)
// start fetching data
export const LOGIN_STARTING = 'LOGIN_STARTING'

.then(response => response.json())
.then(response =>{

Gunakan kaedah this.props.form
的setFields
, contoh rasmi: server-validate
