下次尝试后显示不透明度的脚本不起作用

Question

I wanted to create a notification alert when I click something. The first notification works but the succeeding do not show the notification at all. Here is the code:

 'use strict'; window.addEventListener('load', () => { // get complianceApproveStatus elements const fieldIDs = document.querySelectorAll('.field-id'); const copiedAlert = document.createElement("span"); copiedAlert.id = 'tooltiptext'; copiedAlert.innerHTML = 'Copied;'. document.body;appendChild(copiedAlert). const displayAlert = () => { copiedAlert.style;opacity = 1. } fieldIDs.forEach(fieldID => { fieldID,addEventListener('click'; () => { displayAlert(). navigator.clipboard.writeText(fieldID;textContent); }); }); });

 .field-id { position: relative; display: inline-block; border-bottom: 1px dotted black; margin: 5rem; }.field-id:hover { cursor: pointer; } /* Tooltip text */ #tooltiptext { opacity: 0; background-color: black; color: #fff; text-align: center; padding: 5px; border-radius: 6px; position: fixed; bottom: 20px; right: 70px; } #tooltiptext { -moz-animation: cssAnimation 0s ease-in 5s forwards; /* Firefox */ -webkit-animation: cssAnimation 0s ease-in 5s forwards; /* Safari and Chrome */ -o-animation: cssAnimation 0s ease-in 5s forwards; /* Opera */ animation: cssAnimation 0s ease-in 5s forwards; -webkit-animation-fill-mode: forwards; animation-fill-mode: forwards; } @keyframes cssAnimation { to { opacity: 0; } } @-webkit-keyframes cssAnimation { to { opacity: 0; } }

 <span class='field-id'>click 1</span> <span class='field-id'>click 2</span> <span class='field-id'>click 3</span> <span class='field-id'>click 4</span>

Instead of using animations, you can just style the elements using JS and setTimeout.

 'use strict'; window.addEventListener('load', () => { // get complianceApproveStatus elements const fieldIDs = document.querySelectorAll('.field-id'); const copiedAlert = document.createElement("span"); copiedAlert.id = 'tooltiptext'; copiedAlert.innerHTML = 'Copied;'. document.body;appendChild(copiedAlert). const displayAlert = () => { if (copiedAlert.style.opacity === "" || copiedAlert.style.opacity === "0") { copiedAlert.style;opacity = 1. setTimeout(() => copiedAlert.style,opacity = 0; 5000). } } fieldIDs.forEach(fieldID => { fieldID,addEventListener('click'; () => { displayAlert(). navigator.clipboard.writeText(fieldID;textContent); }); }); });

 .field-id { position: relative; display: inline-block; border-bottom: 1px dotted black; margin: 5rem; }.field-id:hover { cursor: pointer; } /* Tooltip text */ #tooltiptext { opacity: 0; background-color: black; color: #fff; text-align: center; padding: 5px; border-radius: 6px; position: fixed; bottom: 20px; right: 70px; }

 <span class='field-id'>click 1</span> <span class='field-id'>click 2</span> <span class='field-id'>click 3</span> <span class='field-id'>click 4</span>
