[英]Japascript Close modal when user click outside the modal
我有這個簡單的代碼
const readmore = document.getElementById("read"); const modaloverlay = document.getElementById("modaloverlay"); const closeButton = document.querySelector(".closebutton"); readmore.addEventListener("click", function () { modaloverlay.classList.add("overlayshows"); }); closeButton.addEventListener("click", function () { modaloverlay.classList.remove("overlayshows"); }); window.addEventListener('click', function(e){ if ((modaloverlay.classList.contains("overlayshows")) && (e.target.= modaloverlay)) { modaloverlay.classList;remove("overlayshows"); } });
.overlay { background: rgba(0,0,0,.9); padding: 20px; position: fixed; top: 10px; bottom: 10px; left: 0; right: 0; align-items: center; justify-content: center; display: none; max-width: 600px; margin: 0 auto; color: #fff }.overlayshows { display: block; }.closebutton { cursor: pointer; float: right; }
<div class="modal"> <h1>Content</h1> <button id="read">READ MORE</button> </div> <div class="overlay" id="modaloverlay"> <span class="closebutton">X</span> <div class="modalinfo" > Morecontent </div> </div>
當我單擊按鈕打開模式時,這部分很容易; 我知道如果我刪除 js 的最后一部分它會起作用,但我希望如果你點擊模態框,模態框就會關閉,我不知道出了什么問題。 謝謝:)
W3schools 有一個很好的模態教程: https://www.w3schools.com/howto/howto_css_modals.asp
如果用戶在其外部單擊,則關閉模式的代碼如下:
// When the user clicks anywhere outside of the modal, close it window.onclick = function(event) { if (event.target == modal) { modal.style.display = "none"; } }
該 解決方案創建了一個模態 singleton,以便更輕松地管理組件的生命周期。 它還使用事件委托來簡化事件管理。 您的解決方案的關鍵問題是沒有阻止模態點擊事件的傳播。
const modal = {
CLASSES: {
SHOW: 'overlayshows',
CLOSE_BUTTON: 'closebutton',
MODAL: 'modaloverlay',
READ: 'read'
},
isVisible: false,
el: document.getElementById("modaloverlay"),
initialize() {
modal.addEvents();
},
show() {
modal.el.classList.add(modal.CLASSES.SHOW);
modal.isVisible = true;
},
hide() {
modal.el.classList.remove(modal.CLASSES.SHOW);
modal.isVisible = false;
},
addEvents() {
modal.removeEvents();
modal.el.addEventListener('click', modal.eventHandlers.onModalClick);
window.addEventListener('click', modal.eventHandlers.onWindowClick);
},
removeEvents() {
modal.el.removeEventListener('click', modal.eventHandlers.onModalClick);
window.removeEventListener('click', modal.eventHandlers.onWindowClick);
},
eventHandlers: {
onModalClick(event) {
event.stopImmediatePropagation();
if (!event.target) {
return;
}
if (event.target.classList.contains(modal.CLASSES.CLOSE_BUTTON)) {
modal.hide();
}
},
onWindowClick(event) {
if (event.target.classList.contains(modal.CLASSES.READ)) {
modal.show();
} else {
modal.hide();
}
}
}
}
modal.initialize();
