This article mainly brings you an example of jQuery implementing the anchor point downward smooth scrolling effect. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

Achievement effect:

Implementation principle:

Use jQuery animate() Method to achieve smooth scrolling effect on the page

$(&#39;html, body&#39;).animate({
scrollTop: $(hash).offset().top
}, 800, function(){
window.location.hash = hash;
});

Simple example code:

<!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(&#39;click&#39;, 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&#39;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
   $(&#39;html, body&#39;).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>
<p class="main">
 <section></section>
</p>
<p class="main" id="section2">
 <section style="
   background-color: #03c03c;
   color: #fff;
   font-size: 30px;
   text-align: center">
   SECTION 2
 </section>
</p>

Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.
