How to get data attribute value for selected option?

Question

When I selected he just get value name Ahmad - how can I get the value ahmad zakaria ?

HTML:

<select name="kd_produk" id="family">
    <option value="one"
    data-name= "Ahmad Zakaria"
    data-wife= "My wife">number one</option>
</select>

JS

$("select#family").change(function(){
var name1 = $('select#family').find(':selected').data('name1');
var wife1 = $('select#family').find(':selected').data('wife1');

Answer 1

There is no attribute wife1 or name1 in your markup for the select element's <option /> .

Try removing 1 from each key string that you're passing to the .data() method:

var name = $('select#family').find(':selected').data('name');
var wife = $('select#family').find(':selected').data('wife');

This will ensure the values corresponding to the attrbiutes data-wife and data-name are retrieved as expected:

 var name = $('select#family').find(':selected').data('name'); var wife = $('select#family').find(':selected').data('wife'); console.log('data-name of selected:', name) console.log('data-wife of selected:', wife)
