Setting hidden datalist option values

Question

In the snippet below, I have two methods to choose an item: input with datalist and traditional select with options.

The select element keeps the option values hidde

Answer 1

The correct syntax of datalist is like bellow. Also there is no point to have two options with the same name. I took the JavaScript out of the HTML as it should be. ID attribute of the individual options can be replaced with other attribute.

$(function() {
  $('input[name=chooseOption]').on('input',function() {
    var selectedOption = $('option[value="'+$(this).val()+'"]');
    console.log(selectedOption.length ? selectedOption.attr('id') : 'This opiton is not in the list!');
  });
});
