  • Last Updated : 22 Jan, 2021

jQuery UI | Drag event is triggered when the dialog box is dragged

Learn more about jQuery selectors and events here.

Syntax:

$(".selector").dialog (
   drag: function( event, ui ) {
       console.log('dragged')
   },

Approach:

  • First, add jQuery Mobile scripts needed for your project.
<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>
  • ‘Open Dialog’ button will trigger the click function (#gfg) that will further open the <textarea> in a dialog (#gfg2).
  • drag( event, ui ) : Triggers when mouse is moved. There is callback function attached to this drag which gets triggered whenever mouse is moved. 
    • event :  Type -> Event
    • ui : Type -> Object
    • callback function : function( event, ui ) { console.log(‘dragged’)}

Example 1:

HTML




<!doctype html>
<html lang = "en">
   <head>
      <meta charset = "utf-8">
      <link href
         rel = "stylesheet">
      <script src = "https://code.jquery.com/jquery-1.10.2.js">
         </script>
         </script>
        
  
      <script type = "text/javascript">
         $(function() {
            $( "#gfg2" ).dialog({
          autoOpen: false, 
               drag: function( event, ui ) {
                  console.log('dragged')
               },
            });
            $( "#gfg" ).click(function() {
               $( "#gfg2" ).dialog( "open" );
            });
         });
      </script>
   </head>
     
   <body>
      <div id = "gfg2" title="GeeksforGeeks">
         <textarea>jQuery UI | drag(event, ui) Event</textarea>
      </div>
      <button id = "gfg">Open Dialog</button>
   </body>
