This time I will bring you jquery to implement the mouse prompt function of the navigation menu. What are the precautions for jquery to implement the mouse prompt function of the navigation menu. The following is a practical case, let's take a look.

This is a wonderful navigation menu mouse prompt effect, commonly known as "link prompt". Placing the mouse on a link in the navigation menu will display the general content of the web page pointed to by the link, prompting the user to reach the required page. .

Let’s take a look at the screenshot of the running effect first:

The specific code is as follows:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>链接提示特效</title>
<script type="text/javascript" src="jquery1.3.2.js"></script>
<script type="text/javascript"> 
$(document).ready(function(){
 $(".menu a").hover(function() {
  $(this).next("em").animate({opacity: "show", top: "-75"}, "slow");
 }, function() {
  $(this).next("em").animate({opacity: "hide", top: "-85"}, "fast");
 });
});
</script>
<style type="text/css"> 
body {
 margin: 10px auto;
 width: 570px;
 font: 75%/120% Arial, Helvetica, sans-serif;
}
