这次给大家带来jQuery操作锚点动态位移，jQuery操作锚点动态位移的注意事项有哪些，下面就是实战案例，一起来看一下。

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>
<scriptsrc="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>
<ahref="#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>
<pclass="main">
 <section></section>
</p>
<pclass="main"id="section2">
 <sectionstyle="
 background-color: #03c03c;
 color: #fff;
 font-size: 30px;
 text-align: center">
 SECTION 2
 </section>
</p>
</body>
</html>
