jQuery Count Selected Options - Javascript

In this tutorial, we will discuss how to count selected options in a select dropdown list using jQuery.

HTML Markup

We will start by creating a simple HTML dropdown list with some options. Here is the HTML code:

<select id="mySelect">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
  <option value="4">Option 4</option>
</select>

jQuery Code

To count the number of selected options in the dropdown list, we will use jQuery. Here is the jQuery code:

$(document).ready(function() {
  $('#mySelect').change(function() {
    var selectedCount = $(this).find('option:selected').length;
    console.log(selectedCount);
  });
});

In this code, we have used the change event of the select list to trigger a function that counts the number of selected options. The find() method is used to find all the selected options and the length property is used to count the number of selected options.

Conclusion

So, in this tutorial, we have learned how to count selected options in a select dropdown list using jQuery. You can use this code snippet in your own projects to handle similar scenarios.
