如何获取所选选项的数据属性值？

Question

当我选择了他刚刚得到的值名称Ahmad -我怎样才能得到价值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

在选择元素的<option />标记中，没有属性wife1或name1 。

尝试从传递给.data()方法的每个键字符串中删除1 ：

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

这将确保与attrbiutes data-wife和data-name对应的值按预期方式检索：

 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)
