I have the following code:

jsonOptions = [{"description": "Carro 1", "product": "4"},
                {"description": "Carro 2", "product": "5"},
                {"description": "Carro 3", "product": "6"},
                {"description": "Carro 4", "product": "7"},
                {"description": "Carro 5", "product": "8"}

              ];

I use it to fill a <select> using the value of description to build <option>

jsonOptions.forEach(function(item) {

    var option = document.createElement('option');
    option.text = item.description;
    dataList.appendChild(option);
});

What I am not able to do is: When I select one of the options, it sends the value that was captured, so in case, if I select the first value it returns me the text "Car 1". Show!

What I needed was type, if the value selected was Car 1, it picks up the second value and tosses in a variable. It would be like:

Send car 1 to a variable Then fetch the second value "4" and play to another variable

Assign the value of option :

jsonOptions.forEach(function(item) {

    var option = document.createElement('option');
    option.text = item.description;
    option.value = item.product;
    dataList.appendChild(option);
});
