I´m building some modals for fun but I can´t make it work for multiple modals.
useModal hook
import { useState } from 'react';
const useModal = () => {
const [isShowing, setIsShowing] = useState(false);
const toggle = () => {
setIsShowing(!isShowing);
}
return {
isShowing,
toggle,
}
};
export default useModal;
Modal component
import React, { useEffect } from 'react';
const Modal = (props) => {
const { toggle, isShowing, children } = props;
useEffect(() => {
const handleEsc = (event) => {
if (event.key === 'Escape') {
toggle()
}
};
if (isShowing) {
window.addEventListener('keydown', handleEsc);
}
return () => window.removeEventListener('keydown', handleEsc);
}, [isShowing, toggle]);
if (!isShowing) {
return null;
}
return (
<div className="modal">
<button onClick={ toggle } >close</button>
{ children }
</div>
)
}
export default Modal
in my Main component
If I do this the only modal in the page works fine
const { isShowing, toggle } = useModal();
...
<Modal isShowing={ isShowing } toggle={ toggle }>first modal</Modal>
but when I try to add another one it doesn´t work. it doesn´t open any modal
const { isShowingModal1, toggleModal1 } = useModal();
const { isShowingModal2, toggleModal2 } = useModal();
...
<Modal isShowing={ isShowingModal1 } toggle={ toggleModal1 }>first modal</Modal>
<Modal isShowing={ isShowingModal2 } toggle={ toggleModal2 }>second modal</Modal>
what I´m doing wrong? thank you

Try that:
const useModal = () => {
const [isShowing, setIsShowing] = useState(false);
const toggle = () => {
setIsShowing(!isShowing);
};
return [isShowing, toggle];
};
then:
export default function App() {
const [isShowing, toggle] = useModal();
const [isShowingModal1, toggleModal1] = useModal();
const [isShowingModal2, toggleModal2] = useModal();
if you have multiple modal then dynamically inject <div>
inside the page body and map modal to it. to create div use,
var divTag = document.createElement("div");
divTag.setAttribute('id', 'modal');
document.getElementsByTagName('body')[0].appendChild(divTag);
document.getElementById('modal').innerHTML = modalHtML;
This should work.
