How to Simulate a Readonly Attribute for HTML Select Tags While Maintaining POST Data?

Emulating Readonly Attributes for HTML Select Tags While Retaining POST Data

In HTML, the select tag lacks a dedicated readonly attribute, with only a disabled attribute available. However, disabling form inputs prevents their inclusion in POST or GET requests.

To address this, a workaround involves disabling the select element and adding a hidden input with the same name and value. When the select element is enabled, its value is copied to the hidden input, effectively mimicking a readonly attribute.

Here's an example implementation:

$('#mainform').submit(function() {
    $('#formdata_container').show();
    $('#formdata').html($(this).serialize());
    return false;
});

$('#enableselect').click(function() {
    $('#mainform input[name=animal]')
        .attr("disabled", true);
    
    $('#animal-select')
        .attr('disabled', false)
        .attr('name', 'animal');
    
    $('#enableselect').hide();
    return false;
});

By manipulating the disabled attribute and copying values between the select and hidden input, this approach emulates the functionality of a readonly attribute while allowing data to be posted.
