Javascript - How to get data-value of selected option on select change in jquery

To get the data-value attribute of the selected option when the selection changes in jQuery, you can use the change event handler on the <select> element. Here's how you can do it:

HTML:

<select id="mySelect"> <option value="1" data-value="foo">Option 1</option> <option value="2" data-value="bar">Option 2</option> <option value="3" data-value="baz">Option 3</option> </select>

JavaScript (jQuery):

$(document).ready(function() { $('#mySelect').change(function() { var selectedOption = $(this).find(':selected'); var dataValue = selectedOption.data('value'); console.log('Selected data-value:', dataValue); }); });

In this code:

  • We're using jQuery to listen for the change event on the <select> element with the id mySelect.
  • When the selection changes, we find the selected option using find(':selected').
  • Then, we use the .data('value') method to retrieve the value of the data-value attribute of the selected option.
  • Finally, we log the selected data-value to the console. You can replace console.log with any action you want to perform with the selected data-value.

This code will log the data-value attribute of the selected option whenever the selection changes in the <select> element.
