  1. In Oracle Apex, you can use isEmpty() JavaScript API function with apex.item namespace to check if an item is empty or null.

    The following is an example for your requirement:

    if (apex.item("P13_ITEM").isEmpty()) {
    apex.message.alert("Item is empty");
} else {
    apex.message.alert(apex.item("P13_ITEM").getValue());
}
