ReactJS, find elements by classname in a React Component

Question

I\'ve a React component. Some elements will be inserted through the children. Some of these elements will have a specific classname. How can I get a list of these DOM nodes

Answer 1

You can achieve it, via findDOMNode of react-dom, like below:

ReactDOM.findDOMNode().getElementsByClassName('snap') // Returns the elements

If you need the count,

ReactDOM.findDOMNode().getElementsByClassName('snap').length
