I have a piece of code which makes it possible to open a modal by clicking on a button and to close it again by clicking on the same button. I would like it to be possible to close the modal by clicking anywhere on the screen, so not just this button.
I found a lot of pieces of code online on how to do this, but since I am a beginner with JavaScript it is very hard for me to incorporate new pieces of code within my own and make it work. Can someone help me solve this, and explain my how I and where I need to add/change lines in my existing code?
Here is the link to see how the modal works right now (button top right of the screen): https://carbonrollercoaster.bsqd.me/
JavaScript
const bf = document.querySelector('#botsquad-frame');
let el = document.createElement('div');
el.setAttribute('id', 'mijnKnopje');
const inhoud = `
<div class="info-content">
<p1>INFORMATIE: <br>

<div class="info-section">
<a role="button" class="knopje info-button" style="background-color:mediumpurple">
<div class="info-label">!</div>
</a>
</div>
`;
el.innerHTML = inhoud;
bf.appendChild( el );
const mijnKnopje = document.querySelector('.knopje');
const mijnInfo = document.querySelector('.info-content');
mijnKnopje.addEventListener('click', () => {
//mijnInfo.style.display = 'block';
//mijnKnopje.style.backgroundColor = 'fuchsia';
mijnKnopje.classList.toggle( 'active' );
mijnInfo.classList.toggle( 'active' );
let inputField = document.querySelector('.chat-input');
if ( mijnInfo.classList.contains( 'active' ) ) {
inputField.style.display = 'none';
} else {
inputField.style.display = 'revert';
}
} );
Try using event delegation.
Here's a minimal reproducable example to work with.
document.addEventListener(`click`, handle);
function createOrDestroyPopupDummy(create) {
const inhoud = `
<div id="popup">
<h3>INFORMATIE</h3>
<div>

<h3>HOW TO</h3>
<div>

</div>
<div>
<button id="closeInfo">Gezien!</div>
</div>
</div>`;
const popupOpen = document.querySelector(`#popup`);
const createBox = () => document.body.insertAdjacentHTML(`beforeend`, inhoud);
const destroyBox = () => popupOpen && popupOpen.remove();
return create ? createBox() : destroyBox();
}
function handle(evt) {
// show 'popup'
if (evt.target.id === "info") {
return createOrDestroyPopupDummy(true);
}
// do nothing if within the box and not clicked button#closeInfo
if (evt.target.id !== `closeInfo` && evt.target.closest(`#popup`)) {
return;
}
// otherwise destroy the 'popup'
return createOrDestroyPopupDummy();
}#closeInfo {margin-top: 0.5rem;}
#popup {
border: 2px solid green;
box-shadow: 2px 2px 8px #999;
width: 75vw;
padding: 0.4rem;
position: absolute;
top: 50%; right: 50%;
transform: translate(50%,-50%);
}
#popup h3 {
margin-top: 0.2rem;
margin-bottom: 0.1rem;
}<button id="info">Info</button>You could add another event listener for the whole div-info-content aka const mijnInfo and remove the active class when clicked:
const mijnInfo = document.querySelector('.info-content');
mijnInfo.addEventListener('click', () => {
mijnKnopje.classList.remove( 'active' );
mijnInfo.classList.remove( 'active' );
document.querySelector('.chat-input').style.display = 'revert';
});
