I have 2 const我有 2 个常量
const a = data.hi?.map((e) =>
e?.hello?.label.toString()
);
const b = data.hi?.map((e) =>
e?.bye?.label.toString());
currently, I have 2 buttons目前,我有 2 个按钮
<>
<Button> A </Button>
<Button> B </Button>
</>
I also have input text and state我也有输入文本和 state
const [text, setText] = useState("");
<TextArea value={text} />
and so I am looking for when I click on button "A", it returns the value of my const "a" in my TextArea.所以我正在寻找当我点击按钮“A”时,它会在我的TextArea中返回我的const“a”的值。
