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
You can select using exact selected option : Below will give innerText
$("select#aioConceptName > option:selected").text()
While below will give you value.
$("select#aioConceptName > option:selected").val()
