I'm with the final project, and I'm stuck in one of my forms. I have 4 combobox with different options to select. What I'm looking for is that, if in a combobox I select one of the options, it can not be selected in any of the others, to avoid repetitions of the same option.

Ask what you want if you need to solve any more questions, or any part of the exact code.

First of all we should have our select: something like this:

<form id="myform">
<label for="nota1">Nota1:</label>
<select id="nota_1" onchange="validar();">
<option selected disable>Seleccione</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="30">30</option>
</select>
<br>
<label for="nota2">Nota2:</label>
<select id="nota_2" onchange="validar();">
<option selected disable>Seleccione</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="30">30</option>
</select>
</form>

in this case the select can do it from a django form and with the added attributes or widgets the onchange event that I use to call a function that validates the selection of each select.

function validar(){

  var select1 = $("#nota_1").val();
  var select2 = $("#nota_2").val();
  if (select1 ==select2 ){
    alert("Seleccione valores distintos !!");
    //reset form
    document.getElementById('myform').reset();
  }
    return false;
}//end function validar

What I do in this function is first get the values of each select by its id, this can be done by id, class..etc .. and then valid if they are the same and send an alert .. something basic and I apply a reset to the form .. it depends on your logic or what you want to do .. but it is a basic example and I hope it will be your guide. !!

full code:

<form id="myform">
<label for="nota1">Nota1:</label>
<select id="nota_1" onchange="validar();">
<option selected disable>Seleccione</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="30">30</option>
</select>
<br>
<label for="nota2">Nota2:</label>
<select id="nota_2" onchange="validar();">
<option selected disable>Seleccione</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="30">30</option>
</select>
</form>
<script>
function validar(){

  var select1 = $("#nota_1").val();
  var select2 = $("#nota_2").val();
  if (select1 ==select2 ){
    alert("Seleccione valores distintos !!");
    //reset form
    document.getElementById('myform').reset();
  }
    return false;
}//end function validar
</script>
