如何启用一个jQuery UI菜单

jQuery UI由GUI部件、视觉效果和使用jQuery、CSS和HTML实现的主题组成。jQuery UI非常适合为网页构建UI界面。

语法:

$(".selector").menu( "enable" );

方法：首先，添加你的项目所需的jQuery UI脚本。

<link href = “https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css” rel = “stylesheet”>
<script src = “https://code.jquery.com/jquery-1.10.2.js”></script>
<script src = “https://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>

例子1：在这个例子中，我们将为我们的目的创建和启用菜单。

<!doctype html>
<html lang = "en">
   <head>
      <meta charset = "utf-8">
      <link href = 
"https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css"
         rel = "stylesheet">
      <script src = "https://code.jquery.com/jquery-1.10.2.js"></script>
  
      <script src = "https://code.jquery.com/ui/1.10.4/jquery-ui.js">
      </script>
  
      <style>
         .ui-menu {
            width: 200px;
         }
      </style>
        
      <script>
          $(function() {$ ( "#gfg" ).menu();
            $( "#gfg" ).menu("enable");
         });
      </script>
   </head>
     
   <body>
      <h1>jQuery UI | enable menu </h1>
      <ul id = "gfg">
         <li><a href = "https://www.geeksforgeeks.org/">1st</a></li>
         <li><a href = "https://www.geeksforgeeks.org/">2nd</a></li>
         <li><a href = "https://www.geeksforgeeks.org/">3rd</a></li>
         <li><a href = "https://www.geeksforgeeks.org/">2th</a></li>
         <li><a href = "https://www.geeksforgeeks.org/">5th</a></li>
      </ul>
   </body>
</html>
