Necesito alertar si la opción está seleccionada en otro valor de opción de selección. Deshabilité la opción si la seleccioné, pero no puedo insertarla en la base de datos debido al atributo deshabilitado. así que solo quiero alertar.

Esta función de cambio deshabilita la opción si se selecciona otra opción de selección. Cuando cambio para alertarlo, no funciona. Cómo alertar solo si está seleccionado en otra opción de selección.
$('.input_slip_no').on('change', function() {
var selected_options = $('.input_slip_no').map(function(){
return this.value
}).get();
$('.input_slip_no option').each(function(index) {
$(this).prop('disabled', $.inArray($(this).val(), selected_options) != -1);
});
});
Aquí tienes el selector de jQuery como se muestra a continuación,
Nota : He agregado un elemento vacío como valor seleccionado inicial ya que se seleccionó el mismo valor en su muestra anterior.
$('.input_slip_no').change(function(){
var selected = $(this).val();
if(selected) {
var otherSelected = $('.input_slip_no').not($(this)).find('option[value="' + selected + '"]:selected');
if(otherSelected.length > 0) {
alert('Option is already selected');
$(this).val('');
}
}
