I am using react-bootstrap-validation that decorates the react-bootstrap Input tag.

The ValidatedInput requires that it is inside a Form component. When I add my ValidatedInput to a custom sub component I get an error saying it needs to be inside a Form which it is, but I guess it is further down the tree now so can not see the Form.

Is there a way of referencing the parent Form so the ValidatedInput can see the parent.

Looking at the source of the Validation lib I can see that the ValidationInput needs to register to the Form but am not sure how to do this from the sub component. 

// Parent render 
render(){
   <Form
   className="fl-form fl-form-inline fl-form-large"
   name="customer-details"
   onValidSubmit={this._handleValidSubmit}
   onInvalidSubmit={this._handleInvalidSubmit}
   validationEvent='onChange'>
    
     <TitleSelect handleChange={this.updateDropDown} value={this.state.form.title} />
     
   </form>
}


// Sub class containing the ValidatedInput
export class TitleSelect extends React.Component {

    static propTypes = {
      handleChange: React.PropTypes.func.isRequired,
      value: React.PropTypes.string.isRequired
    }

    render(){

        return (
          <ValidatedInput
            name="title"
            label='title'
            type='select'
            value={this.props.value}
            onChange={this.props.handleChange}
            groupClassName='form-group input-title'
            wrapperClassName='fl-input-wrapper'
            validate='required'
            errorHelp={{
              required: 'Please select a title.'
            }}>

            <option value="" ></option>
            <option value="Mr">Mr</option>
            <option value="Mrs">Mrs</option>
            <option value="Master">Mstr.</option>
            <option value="Ms">Ms</option>
            <option value="Miss">Miss</option>
            <option value="Reverend">Rev.</option>
            <option value="Doctor">Dr.</option>
            <option value="Professor">Prof.</option>
            <option value="Lord">Lord</option>
            <option value="Lady">Lady</option>
            <option value="Sir">Sir</option>
            <option value="Master">Mstr.</option>
            <option value="Miss">Miss</option>
          </ValidatedInput>
        )
    }
};

At the moment this is impossible to do. It will be possible in a future release once we get proper parent-based contexts in react and I will migrate the component to contexts. But for now I would recommend to split your render() method to couple of smaller ones and reuse them.

Sa @Ваня Решетников 上面说过，由于当前设计的限制，现在不可能做到。我寻求的解决方案是这样的。

  1. 将子组件转换为纯 JS 对象

    TitleSelect = {
  // move prop types to parent
  renderTitleSelect(){
    ...
  }
}

  2. 将新对象作为 mixin 添加到父对象并渲染函数

    mixins: [TitleSelect],
...
render() {
  <Form ...>
    // parentheses are important!
    {this.renderTitleSelect()}
  </Form>
}
