@formConnect(schemas, methods) export default class BasicForm extends React.Component { static propTypes = { formControl: PropTypes.object, }; constructor(props) { super(props); props.formControl.init({ email: '', phone: '', }, { static: 'form-control', success: 'valid-success', error: 'valid-error', }); } handleSubmit = async () => { const { formControl } = this.props; if (await formControl.validate()) { // Submit. } }; render() { return ( <div className="form-group"> <Text name="email" placeholder="Please input your email" delay={100} // Asynchronous validation /> <Message className="valid-error-message" name="email" /> <Text name="phone" /> <button onClick={this.handleSubmit}>提交</button> </div> ); } }Validate methods can refer to validate-framework-utils

const { formControl: { fields, onFormChange, }, } = this.props; return ( <input className={fields.email.className} name="email" type="text" onChange={onFormChange} value={fields.email.value} placeholder="Please input your email" /> );API
