}
</style>
</head>
<body>
<div class="parent">
<div class="child">This is a child element.</div>
<div>This is another child element.</div>
</div>
<button onclick="hideChild()">Hide Child</button>
<script>
function hideChild() {
const child = document.querySelector('.child');
child.style.display = 'none';
}
</script>
</body>
</html>
display: none
可以完全移除元素占据的空间,而 visibility: hidden
和 opacity: 0
则不会。display: none

可以避免子元素被交互,而 opacity: 0
则不会。DOMContentLoaded
事件。document.addEventListener('DOMContentLoaded', function() {
const child = document.querySelector('.child');
child.style.display = 'none';
});
