React 0.13 this.getDOMNode() equivalent to React.findDOMNode()

by

Update React v0.14+

In React v0.14+ this has changed, you should now use the react-dom module:

import ReactDOM from 'react-dom';

ReactDOM.findDOMNode(this);

ES6

class Test extends React.Component {
  componentDidMount() {
    const element = ReactDOM.findDOMNode(this);
    console.log(element);
    alert(element);
  }
  
  render() {
    return (
      <div>test</div>
    );
  }
}

ReactDOM.render(<Test />, document.getElementById('r'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.js"></script>
<div id="r" />

ES5

var Test = React.createClass({
  componentDidMount: function() {
    var dom = ReactDOM.findDOMNode(this);
    console.log(dom);
    alert(dom);
  },
  render: function() {
    return React.createElement('div', null, 'test');
  }
});

ReactDOM.render(React.createElement(Test), document.getElementById('r'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.js"></script>
<div id="r" />

React v0.13 and below

Passing this as the parameter should definitely work:

React.findDOMNode(this);

If not, something else may be going on. See demo below:

var Test = React.createClass({
  componentDidMount: function() {
    var dom = React.findDOMNode(this);
    console.log(dom);
    alert(dom);
  },
  render: function() {
    return React.DOM.div(null, 'test');
  }
});

React.render(React.createElement(Test), document.getElementById('r'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.1/react.js"></script>
<div id="r"></div>
