jQuery右侧圆点导航菜单是一种常见的网页设计元素,通常用于显示当前页面在网站结构中的位置。这种导航菜单通常由一系列圆点组成,每个圆点代表一个页面或一个部分,当前页面对应的圆点会被高亮显示。
以下是一个简单的jQuery右侧圆点导航菜单的实现示例:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>jQuery Right Dot Navigation</title>
<style>
.dot-nav {
position: fixed;
right: 20px;
bottom: 20px;
display: flex;
flex-direction: column;
align-items: center;
}
.dot {
width: 10px;
height: 10px;
border-radius: 50%;
background-color: #ccc;
margin: 5px;
cursor: pointer;
}
.dot.active {
background-color: #007bff;
}
</style>
</head>
<body>
<div class="content">
<!-- 页面内容 -->
<h1>Section 1</h1>
<p>Content for section 1...</p>
<h1>Section 2</h1>
<p>Content for section 2...</p>
<h1>Section 3</h1>
<p>Content for section 3...</p>
</div>
<div class="dot-nav">
<div class="dot active" data-section="section1"></div>
<div class="dot" data-section="section2"></div>
<div class="dot" data-section="section3"></div>
</div>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function() {
$('.dot').click(function() {
var section = $(this).data('section');
$('html, body').animate({
scrollTop: $('#' + section).offset().top
}, 1000);
});
$(window).scroll(function() {
var scrollPosition = $(this).scrollTop();
$('.content h1').each(function() {
var currentSection = $(this);
var sectionTop = currentSection.offset().top;
var sectionHeight = currentSection.outerHeight();
if (scrollPosition >= sectionTop && scrollPosition < (sectionTop + sectionHeight)) {
var sectionId = currentSection.attr('id');
$('.dot').removeClass('active');
$('.dot[data-section="' + sectionId + '"]').addClass('active');
}
});
});
});
</script>
</body>
</html>
