I want to hide child div when clicked outside the child div. Toggle button should also work in this case.
import React, { useState } from "react";
export default function Toggle() {
const [view, setView] = useState(false);
return (
<div style={{ height: "100vh", backgroundColor: "lightblue" }}>
<button onClick={() => setView(!view)}> show/hide </button>
<div
style={{
display: `${view ? "block" : "none"}`,
height: "20vh",
width: "10vw",
backgroundColor: "lightcoral",
}}
>
Child Div
</div>
</div>
);
}One way of doing this is by getting the mouse cursor coordinates on click (using the event) and then adding a conditional statement to setView to false only if the cursor is outside the child div and the view is true.
export default function Toggle() {
const [view, setView] = useState(false);
function hide(e) {
if (e.pageX > 80 || e.pageY > 125) {
if (view) setView(false);
}
}
return (
<div
onClick={() => hide(event)}
style={{ height: "100vh", backgroundColor: "lightblue" }}
>
<button onClick={() => setView(!view)}> show/hide </button>
<div
style={{
display: `${view ? "block" : "none"}`,
height: "20vh",
width: "10vw",
backgroundColor: "lightcoral"
}}
>
Child Div
</div>
</div>
);
}
