示例代码

• 基本示例
• 简单的form到input组件的绑定
• _ReactForm(@kne/current-lib)

const { default: ReactForm, useField, useSubmit, useReset } = _ReactForm;

const Input = props => {
  const fieldProps = useField(props);

  return (<div>
    {fieldProps.label}
    <input ref={fieldProps.fieldRef} type="text" value={fieldProps.value || ''} onChange={fieldProps.onChange}
           onBlur={fieldProps.triggerValidate} />
    {fieldProps.errState}
    {fieldProps.errMsg}
  </div>);
};

const SubmitButton = ({ children }) => {
  const { isLoading, onClick } = useSubmit();
  return (<button onClick={onClick}>
    {children}
    {isLoading ? '正在提交中...' : ''}
  </button>);
};

const ResetButton = () => {
  const { onClick } = useReset();
  return <button onClick={onClick}>重置</button>;
};

const BaseExample = () => {
  return <div>
    <ReactForm data={{
      name: '哈哈哈'
    }} onSubmit={(data) => {
      console.log('submit:', data);
    }}>
      <Input name="name" label="名称" rule="REQ LEN-0-10" />
      <div>
        <SubmitButton>提交</SubmitButton>
        <ResetButton>重置</ResetButton>
      </div>
    </ReactForm>
  </div>;

render(<BaseExample />);
