How to use?

npm i react-validate-framework --save

Import:

import formConnect, {
  Checkbox,
  Radio,
  Select,
  Text,
  Textarea,
  Message,
} from 'react-validate-framework';

Rules and messages like this:

const schemas = {
  email: {
    rules: 'required | isEmail | maxLength(32) | validateFromServer',
    messages: 'Can not be empty! | Please enter a valid email address. | Can not exceed {{param}} characters. | | The email already exists.',
  },
  hobby: {
    rules: 'requiredField(phone) | selectLimit(2)',
    messages: 'email and hobby at least one entry! | Select at least {{param}}.',
  },
};

const methods = {
  selectLimit(field, param) {
    if (Array.isArray(field.value)) {
      return field.value.length >= param;
    }
    return false;
  },
  requiredField(field, param) {
    const otherField = this.fields[param];
    return this.required(field) || (otherField.result && this.required(otherField));
  },
  async validateFromServer(field, param) {
    return await doServerAPI();
  },
};

The BasicForm like this:

@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>
    );
  }
}

Form components

• Checkbox
• Radio
• Select
• Text
• Textarea
• Message

The name attribute is required in form components, delay debounce, Other parameters can be overridden.

Of course, you can also use unencapsulated form components, just specify value and onChange on the line:

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"
  />
);
