how to make a selection based on multiple negative criteria?

Question

I already filtered a select element for non multiple selects :

$("select:not([multiple])").select2().on("change", function(e) {
    if ($(this).val() == "") {
      $(this).parent().find("span[role='combobox']").each(function() {
           $(this).attr("data-validate-func", "required").attr("data-validate-hint", "<?php echo _getText('global.champ.obligatoire'); ?>");
      });
    } else {
      $(this).parent().find("span[role='combobox']").each(function() {
           $(this).removeAttr("data-validate-func");
      });
    }
});

Now I want to filter also for select elements not having a Label as its first parent . How to modify my code for that purpose ?

Answer 1

You can use .filter() :

$("select:not([multiple])").filter(function(){
    return $(this).parent().is('label')
}).select2().....

Answer 2

You can add a descendant selector to your :not clause:

$("select:not([multiple], label > select)").select2().on("change", //...
