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 in my outermost Component?
<MyComponent>
<div classname="snap"/>
<p></p>
<div classname="snap"/>
<p></p>
<div classname="snap"/>
</MyComponent>
What I want to know is how many elements with the classname "snap" are inserted in my component.
