I am trying to change a div‘s visibility from hidden to visible using button click. But even when I am clicking the button, the visibility is not changing. I have logged the console after the clickHandler, and it still says false even after I set it to true inside the function. So far, I have this,
let clicked = false;
//change image on fortune cookie click
const clickHandler = (e) => {
e.target.setAttribute(
"src",
"https://i.ibb.co/cksx7kr/kisspng-fortune-cookie-drawing-clip-art-fortune-cookie-5b237469209879-9079770415290502171335.png"
);
clicked = true;
};
console.log(clicked);
return (
<div className="App">
<button onClick={clickHandler}>
<img
className="cookie"
src="https://i.ibb.co/9YQV2qq/kisspng-fortune-cookie-biscuits-bakery-drawing-clip-art-fortune-cookies-5b0ec5e3013c23-3980054715276.png"
/>
</button>
<div
className="fortuneMessage"
style={{ visibility: clicked ? "visible" : "hidden" }}
>
{fortune}
</div>
</div>
);
>Solution :
When you are using React, you need a state in order to have a DOM update. That would fork for you (don’t forget to import useState at the top of your file) :
const [clicked, setClicked] = useState(false);
const [src, setSrc] = useState("https://i.ibb.co/9YQV2qq/kisspng-fortune-cookie-biscuits-bakery-drawing-clip-art-fortune-cookies-5b0ec5e3013c23-3980054715276.png");
//change image on fortune cookie click
const clickHandler = (e) => {
setSrc("https://i.ibb.co/cksx7kr/kisspng-fortune-cookie-drawing-clip-art-fortune-cookie-5b237469209879-9079770415290502171335.png");
setClicked(true);
};
console.log(clicked);
return (
<div className="App">
<button onClick={clickHandler}>
<img
className="cookie"
src={src}
/>
</button>
<div
className="fortuneMessage"
style={{ visibility: clicked ? "visible" : "hidden" }}
>
{fortune}
</div>
</div>
);
