How can I handle redux form submission in child component?

Question

In all examples that I read, we always handle submission of the form from parent component.

For instance:

export default class ParentComponent extends React.Component{
constructor(){
    super();
    this.state = {
        working: false,
        users: []
    }
}
handleSubmit(values){
    //do something
}
render(){
    return(
        <div className="container">
            <ReduxForm onSubmit={this.handleSubmit.bind(this)} {...this.props}/>
        </div>
    );
}
}

and in child component

class ReduxForm extends React.Component{
constructor(){
    super();
}
render(){
    const {handleSubmit, pristine, reset, submitting } = this.props;
    return(
        <div>
            <h2>Hello, Redux form</h2>
            <form onSubmit={handleSubmit}>
                <div className="form-group">
                    <label htmlFor="firstName">First Name</label>
                    <Field name="firstName" component="input" type="text" className="form-control"/>
                </div>
                <div className="form-group">
                    <label htmlFor="lastName">Last Name</label>
                    <Field name="lastName" component="input" type="text" className="form-control"/>
                </div>
                <div className="form-group">
                    <button type="submit" className="btn btn-success">Submit</button>
                </div>
            </form>
        </div>
    );
}
}

I think we should handle the submission in ReduxForm (child component) for reusable (what if we have another page, use that form again and we have to handle submission every time?)

I tried to handle the submission in redux form way, but it's not success.

Any idea?

Thank you so much!

You can delegate the submission callback to the function of your choice

class ReduxForm extends React.Component{
   constructor(){
      super();
      this.submit = this.submit.bind(this);
   }
   submit(values) {
      alert('SUBMIT : ' + JSON.stringify(values));
   }
   render(){
      const { handleSubmit } = this.props;
      return ( 
         <form onSubmit={handleSubmit(this.submit)}>
         //                           ^^^^^^^^^^^
         //                           Your submission handler
         // ...
         </form>
   }
}
