Set New ID Attribute with jQuery

jQuery Web Development Front End Technology

To implement this, extract id from attr() and use replace() to replace the id attribute.

Example

Following is the code −

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<body>
   <div id="first-name">
</body>
<script>
   $('[id*="-"]').each(function () {
      console.log('Previous Id attribute: ' + $(this).attr('id'));
      $(this).attr('id', $(this).attr('id').replace('-', '----'));
      console.log('Now Id Attribute: ' + $(this).attr('id'));
   });
</script>
</html>

To run the above program, save the file name “anyName.html(index.html)”. Right click on the file and select the option “Open with Live Server” in VS Code editor.
