Did you try that ? I mean – why are you counteracting a functional usable piece of code with your – “why not?”-stuff.
Well then I will tell why not:
First – BECAUSE it DOES NOT work
Second – Im not gonna debug your “Why not”-stuff to find out WHY NOT

$(document).ready(function() {
$(‘input[type=file]‘).each(function(){
$(this).addClass(‘file’).addClass(‘hidden’);
$(this).parent().append($(”).append($(”).attr(‘id’,$(this).attr(‘id’)+’__fake’)).append($(”)));

$(this).bind(‘change mouseout’, function() {
$(‘#’+$(this).attr(‘id’)+’__fake’).val($(this).val());;
});

});
});
