导航鼠标点击JS特效是指通过JavaScript编程实现的,在用户点击导航菜单项时触发的视觉效果。这些特效可以增强用户体验,使网站更加吸引人。
以下是一个简单的导航鼠标点击JS特效示例,实现点击导航项时的淡入淡出效果:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Navigation Click Effect</title>
<style>
.nav-item {
padding: 10px;
margin: 5px;
cursor: pointer;
border: 1px solid #ccc;
}
.content {
display: none;
padding: 20px;
border: 1px solid #000;
}
.active {
display: block;
}
</style>
</head>
<body>
<div class="nav">
<div class="nav-item" onclick="showContent(1)">Item 1</div>
<div class="nav-item" onclick="showContent(2)">Item 2</div>
<div class="nav-item" onclick="showContent(3)">Item 3</div>
</div>
<div id="content1" class="content active">Content for Item 1</div>
<div id="content2" class="content">Content for Item 2</div>
<div id="content3" class="content">Content for Item 3</div>
<script>
function showContent(num) {
// Hide all content
var contents = document.getElementsByClassName('content');
for (var i = 0; i < contents.length; i++) {
contents[i].classList.remove('active');
}
// Show selected content with fade in effect
var contentToShow = document.getElementById('content' + num);
contentToShow.classList.add('active');
contentToShow.style.opacity = 0;
var fadeIn = setInterval(function () {
if (contentToShow.style.opacity < 1) {
contentToShow.style.opacity += 0.1;
} else {
clearInterval(fadeIn);
}
}, 50);
}
</script>
</body>
</html>
