class - ReactJS - Call One Component Method From Another Component

Question

I have two components. I want to call a method of the first component from the second component. How can I do it?

Here is my code.

First Component

class Header extends React.Component{

    constructor(){
        super();
    }

    checkClick(e, notyId){
       alert(notyId);
    }
}

export default Header;

Second Component

class PopupOver extends React.Component{

    constructor(){
        super();
        // here i need to call Header class function check click....
        // How to call Header.checkClick() from this class
    }

    render(){
        return (
            <div className="displayinline col-md-12 ">
                Hello
            </div>
        );
    }
}

export default PopupOver;

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true
