It seems you have used a wrong method.

Probably you should use getElementsByClassName instead of getElementByClassName. And DO NOT forget getElementsByClassName returns an array-like obj HTMLCollection, so picking the first element is necessary.

React.render(

  document.getElementsByClassName('className')[0]
);
