Serialize the prototype strictly based on the visible form field

Question

Serialize the prototype strictly based on the visible form field

Is there a way to serialize only the visible form field values in prototype.js? I have a form where two elements share the same name, but one is visible while the other is hidden. When I serialize the form using $('formid').serialize(), both field values are included in the output like this:

<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="384d4b5d4a675d5559515405595a5b785d40595548545d165b">[email protected]</a>&mymodule_custom_delivery_area=20&mymodule_custom_delivery_area=test

The first element was a dropdown, while the second was a text box. The text box was hidden, and the dropdown was visible. They have the same name. I only want to include the value of the visible dropdown. How can I achieve this? Thank you

Caution: This solution may be incomplete, but can be used as a starting point for a more robust one:

While I haven't found a universal method to tackle this issue, my current solution works if the input element is directly hidden. However, it falls short if the input is nested within another hidden element.

Here is my current approach:

function check() {
    var inputs = $("myform").getElements();
    var visibleInputs = inputs.grep({ match: function(elem) { return elem.visible();} });
    var serialized = Form.serializeElements(visibleInputs);
    console.log(serialized); // take action with the data here
}

The first line retrieves a list of all form fields. The second line filters out only the visible elements using a multidimensional array with a dummy match function. Finally, the visible elements are serialized.

Is there a way to enhance this solution to exclude input fields hidden within parent elements? One potential approach involves a complex match function that traverses up the DOM tree to check if each parent is hidden.
