Inserting a Value into otherTable using an App. Proc. from a Date Picker

Question

I'm trying to call an Application Process that will insert an Attribute of a Row, into another table, after selecting a date from a Date Picker cell.
I don't know why this shouldn't be possible. I think I've got all of my "Ducks in a Row", so to speak,
but the Value that is being inserted into the other table is this:.. [object HTMLTableCellElement]
(Ultimately, I'd like my Application Process to include Page element values with the insert as well, but I'm trying to handle one problem at a time)
Here's a list of all the steps I've covered:
1. I've Created an Application Process, (popDevices). The Process Point is "On-Demand". The Type is "PL/SQL Anonymous Block".
The Process is defined as such:
BEGIN
Insert into P_DEVICES
NAME,
IP_ADDRESS,
MODEL
) values
'Unassigned',
'Unassigned',
:P153_MODEL
COMMIT;
END;
2. I've Included the Javascript in the Page HTML Header.
The Javascript is written as such: (minus the tags)
function popDevices(PART_NO)
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=popDevices',0);
get.add('P153_MODEL',PART_NO);
gReturn = get.get();
get = null;
3. I've included the following in the "Element Attributes" field of the Date-Picker Item (Date_Delivered).
The Region Type is "SQL Query (Updatable Report)"
onChange="javascript:popDevices(PART_NO);"
THE RESULTS
A. A row does get inserted into the other (P_Devices) table,
But the value of the Attribute from the Page Region is not valid.
The Inserted value is this: [object HTMLTableCellElement]
B. I have tried Every conceivable combination of characters in the "Element Attributes" field, such as:
...(PART_NO), (#PART_NO#), (||PART_NO||), (+PART_NO+)
C. The Javascript in the Page HTML Header appears to be correct, since I have written it this same way for other applications without any problems.
D. If this simply cannot be done by referencing the "onChange" Javascript from the "Element Attributes" field,
Then can you help me to write the code into the Select statement of the region.
Thanks for any help you can give me.

Answer 1

This may not be the most direct approach to the solution. But, none the less, it is a solution.
For those other novices, like myself, I hope this can be useful at some point in your development:
MY DESIRED RESULT:
A. To Insert into another tablle values derived from both; Page Item (i.e. P153_x) and Attributes of a Row in an Updatable Report from which I have selected the Date-Picker.
B. I want the insert to occur automatically after the user Selects the date from the Date-Picker.
SOLUTIONS:
1. I usea Javascript prompt window to prompt for information and store the information in Pre-Created Page Items.
This is the Javascript as I've entered it into the Page HTML Header region: (Minus the Tags)
function received_javaprompt () {
var Serial_Number = prompt("Enter the Serial Number");
var Bldg_Id = prompt("Enter the Bldg_Id");
var Clst_Id = prompt("Enter the Clst_Id");
$x('P153_SERIAL_NO').value = Serial_Number;
$x('P153_BLDG_ID').value = Bldg_Id;
$x('P153_CLST_ID').value = Clst_Id;
2. I needed to identify the (Manufacturer and Part_No) Column Attribute in the Row from which I selected the Date-Picker.
A. To do this, I enumerated the Columns in the order they were listed in the Select Statement of the region (Click on the Region Definition Tab).
B. Then (Click on the Report Attributes Tab). Count, In the numerical order which these columns are selected, ONLY the columns that are Editable.
C. When I counted down as far as the Column I wanted to capture the value of, Then I made a mental note of that number and used it in the following (2) Javascripts (findMaker and findModel).
3. findMaker (Minus the tags)
function findMaker (pThis) {
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
var Maker = html_GetElement('f15_'+vRow).value
$x('P153_MAKER').value = Maker;
4. findModel (Minus the tags)
function findModel (pThis) {
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
var Model = html_GetElement('f16_'+vRow).value
$x('P153_MODEL').value = Model;
5. I added one more Javascript, to the Page HTML Header, that references the Application Process which will Insert the values into the "Other" table:
function popDevices(P153_SERIAL_NO,P153_BLDG_ID,P153_CLST_ID,P153_MAKER,P153_MODEL)
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=popDevices',0);
get.add('P153_SERIAL_NO',P153_SERIAL_NO);
get.add('P153_BLDG_ID',P153_BLDG_ID);
get.add('P153_CLST_ID',P153_CLST_ID);
get.add('P153_MAKER',P153_MAKER);
get.add('P153_MODEL',P153_MODEL);
gReturn = get.get();
get = null;
6. I added the "onChange" process to the Element Attributes field of the Table item which utilizes the Date-Picker:
A. Click on the Report Attributes Tab of the Region.
B. Click on the Edit icon of the column which utilized the Date-Picker
C. I added this "onChange" reference to the Element Attributes field, which is found in the Tabular Form section.
onChange="javascript:received_javaprompt();findModel(this);findMaker(this);popDevices((P153_SERIAL_NO).value,(P153_BLDG_ID).value,(P153_CLST_ID).value,(P153_MAKER).value,(P153_MODEL).value);"
7. The Application Process which inserts the collected data into the table is as follows:
(Name= popDevices: Process Point= On-Demand: Type= PL/SQL Anonymous Block)
BEGIN
Insert into P_DEVICES
BLDG_ID,
CLST_ID,
NAME,
IP_ADDRESS,
SERIAL_NO,
MAKER,
MODEL
) values
:P153_BLDG_ID,
:P153_CLST_ID,
'Unassigned',
'Unassigned',
:P153_SERIAL_NO,
:P153_MAKER,
:P153_MODEL
COMMIT;
END;
Well, I hope this may help someone else like me.
I usually arrive at my solutions by getting help here on the Discussion Forum and also Google. Google inevitably points me to a previous Apex Discussion Forum session.
