Adding Attributes to HTML elements via Jquery

Solution:1

You can add the attributes via jQuery’s .attr() function. The first parameter determines the attribute you’re adding while the second parameter is the value of the said attribute.

Example:

$(document).ready(() => {
  $('#element_id').attr('data-tf-popup', 'Vxs1VOeK');
  $('#element_id').attr('data-tf-hide-header', '');
  // ...
});

You can make it cleaner by using JSON objects as such:

$(document).ready(() => {
  const attr = {
    'data-tf-popup': 'Vxs1VOeK',
    'data-tf-hide-header': '',
    'data-tf-transitive-search-params': 'utm_source, utm_medium,utm_campaign,utm_term,utm_content',
    // ...
  }
  
  for (let key in attr) {
    $('#element_id').attr(key, attr[key]);
  }
});

Solution:2

You can use the jQuery attr() method to add attributes to an HTML element.

In the following example when you click on the “Select Checkbox” button it will add the checked attribute to the checkbox dynamically using jQuery.

Example

Try this code »

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery Adding Attribute to HTML Element</title>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
    $(document).ready(function(){
        $(".add-attr").click(function(){            
            $('input[type="checkbox"]').attr("checked", "checked");
        });
    });
</script> 
</head>
<body>
    <button type="button" class="add-attr">Select Checkbox</button>
    <input type="checkbox"> 
</body>
</html>
