Javascript disable all readonly Dropdowns and send via Form

Readonly select-Tags are not allowed in HTML until now, but can be used.

An alternative would be to use the disabled=true attribute, but this will not send the select value on form submission.

An easy solution would be to disable the selection with Javascript and leave it readonly:

$( document ).ready(function() {
    $('select[readonly="readonly"]').css('pointer-events','none');
});

The only problem is, that you can still tab throw the form and select elements with your keyboard but the mouse can not select element from the dropdown.
