Parsing element on clicking a button

So I want to parse the h2 tag and save its text content into a constant after I the button "select" is clicked

<div className="card " + (this.state.selected ? "methodSelected" : "")>
<h2 className="charge"></h2>
<button onClick=this.selectMethod href="#"className="btn return-btn">SELECT</button>
</div>


The function I'm using to setState after clicking the button

selectMethod = () =>
this.setState(selected: true);

In the selectMethod method you could add -

selectMethod = () =>
this.setState(selected: true);
let x = document.getElementByClassName("charge").textContent;
// doing something with the variable 'x'


From my understanding of the question,this can be done in following way

selectMethod = () =>
document.getElementById('heading').innerHTML="sample text"
this.setState(selected: true);



Also add id attribute to to the heading tag as

id

<h2 id="heading"></h2>
