Example 2: In this example, First the list elements are selected and then passed to a function for sorting. After sorting they are appended to the Parent element using appendTo() method in sorted manner. This example uses the same method as in the first example but with a different approach.
<!DOCTYPE HTML> <html>     <head>         <title>             Sort a list alphabetically         </title>                   <script src =         </script>     </head>           <body>         <h1 style = "text-align:center; color:green;">             GeeksForGeeks         </h1>                   <p id = "GFG_UP" style =             "text-align:center; font-size: 15px; font-weight: bold;">             click on the button to sort the list         </p>                   <ul class="mylist">             <li>a</li>             <li>c</li>             <li>b</li>             <li>B</li>         </ul>         <br>                   <center>             <button>                 click here             </button>         </center>                   <p id = "GFG_DOWN" style =             "text-align:center; color:green; font-size:20px; font-weight:bold;">         </p>                   <script>             function sort(selector) {                 $(selector).children("li").sort(function(a, b) {                     var A = $(a).text().toUpperCase();                     var B = $(b).text().toUpperCase();                     return (A < B) ? -1 : (A > B) ? 1 : 0;                 }).appendTo(selector);             }                           $('button').on('click', function() {                 sort("ul.mylist");                 $("#GFG_DOWN").text("sorted");             });                         </script>     </body> </html>                    |
