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></body></html>
