Using Refs

Refs are used inside components to return references to real DOM elements rendered by React. So, instead of assigning an id or class value to elements, we can assign refs. It's easier to get references to real DOM elements using refs than id or class attributes.

Let's look at a basic example of how to use refs by creating a form. First, create a container element and place it inside the body tag. Here is the code:

<div id="container9"></div>

Here is the code for the form, which uses refs:

var FormComponent = React.createClass({
  clicked: function(){

        <input type="button" value="Click to Submit" onClick={this.clicked} />
      </div>
