Usually I use $(\"#id\").val() to return the value of the selected option, but this time it doesn\'t work. The selected tag has the id aioConceptName
$(\"#id\").val()
aioConceptName
to fetch a select with same class= name you could do this, to check if a select option is selected.
var bOK = true; $('.optKategorien').each(function(index,el){ if($(el).find(":selected").text() == "") { bOK = false; } });
