The issue is you are not specifying the option or selected option of dropdown or list  Here is an example for dropdown  i am assuming a data attribute data-record      select   on  change   function            let element      quot  visiabletoID quot            element val   this  find   selected   data  record

If we want to retrieve or update these attributes using existing  native JavaScript  then we can do so using the getAttribute and setAttribute methods as shown below      Through JavaScript    lt div id  strawberry-plant  data-fruit  12  gt  lt  div gt    lt script gt      Getting  data-attributes using getAttribute var plant   document getElementById  strawberry-plant    var fruitCount   plant getAttribute  data-fruit       fruitCount    12       Setting  data-attributes using setAttribute plant setAttribute  data-fruit   7       Pesky birds  lt  script gt    Through jQuery     Fetching data var fruitCount     this  data  fruit    OR     If you updated the value  you will need to use below code to fetch new value     otherwise above gives the old value which is intially set     And also above does not work in    Firefox     so use below code to fetch value var fruitCount     this  attr  data-fruit        Assigning data   this  attr  data-fruit   7      Read this documentation

Important note  Keep in mind  that if you adjust the data- attribute dynamically via JavaScript it will NOT be reflected in the data   jQuery function  You have to adjust it via data   function as well    lt a data-id  123  gt link lt  a gt    js     this  data  id      returns 123   this  attr  data-id    321      change the attribute   this  data  id      STILL returns 123      this  data  id    321     this  data  id      NOW we have 321
