Hot to get ITEM NAME

Question

Hello,
is it possible to use *#CURRENT_ITEM_NAME#* in a function parameter?
I want a function based validation and create a function. Then I created a element validation in my page with the PL/SQL-Expression Type and insert this code to start the function.
rpf.vornamecheck(:#CURRENT_ITEM_NAME#)= 1
In this point I dont want to insert the name of the Item manualy, because if I change the item name i also have to change it in the parameter of this validation.
I test it a lot of times, but it doesn't work. Is there a other way to get the Name of an item (NOT LABEL)??

I understand completely what you mean and I agree that it would be very good to have more ways to indirectly reference things to avoid
hard coding page numbers and column_names. I am a newbie also and did not know javascript but I quickly discovered that it was easier to deal with javascript than to try to do things via plsql because javascript is easily available in the running page whereas to call plsql you have
to know a lot more about the page load and page submit and partial page refresh and ajax and so forth. I simply do not know myself if there is a way that a change or blur can trigger a plsql check of that which changed. Maybe so using html_db? There's a big gap in my brain regarding that. I have made a personal choice to just go with javascript and not have to tackle the other ways of doing this because they
are actually harder to understand than I am finding it to learn javascript.
This is the two part javascript way. In this example we call a very simple javascript function timehourCheck which is defined in the
javascript section of the page (other locations are possible). If it doesn't like the hour it actually nukes the item value. Note passing this the event object to the function. Some things 'this' has are this.id (the id which is what you asked about) and this.value the value.
so a question would be is there an equivalent plsql based way of creating the kind of information passing that is obtained via the
this event object in javascript?
html form element attributes
for the page item to be checked:
onBlur="timehourCheck(this);"
javascript part of page contains this:
function timehourCheck(thisobj) {
var mytext = thisobj.value;
if (mytext.length == 0)
    {return;}
if (mytext * 1 > 12)
   {alert('ERROR time hour ' + mytext + ' is > 12');
   thisobj.value = '';
if (mytext * 1 < 0)
   {alert('ERROR time hour ' + mytext + ' is < 0');
   thisobj.value = '';
} // end timehourCheck
