jQuery实现锚点向下平滑滚动特效示例
实现效果：
实现原理：
使用jQuery animate()方法实现页面平滑滚动特效
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
window.location.hash = hash;
});简单实例代码：
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});
</script>
<style>
body, html, .main {
height: 100%;
}
section {
min-height: 100%;
}
</style>
</head>
<body>
<a href="#section2" rel="external nofollow" style="
font-size: 30px;
font-weight: bold;
text-align: center;
">点击此处平滑滚动到第二部分</a>
<div class="main">
<section></section>
</div>
<div class="main" id="section2">
<section style="
background-color: #03c03c;
color: #fff;
font-size: 30px;
text-align: center">
SECTION 2
</section>
</div>
