Set select list using description

Hi,
I have been able to provide a value for a select list from another page when providing a code in the P6_NAME field e.g. P5_NAME_ID = &P6_NAME.
I now need to choose an option from a select list using it's description rather than the underlying code the field is based on.
Is this possible?
Toby

So if no other value has been specified already you just want the select list to have a default item already selected, right? OK, how about setting the Default Value Type for the Select List to "PL/SQL Function Body" and setting its Default to:
DECLARE
   l_return_id number;
BEGIN
   SELECT id
   INTO l_return_id
   FROM my_lookup_table
   WHERE description = 'Description of your default lookup value';
   return l_return_id;
END IF;Andy

Create a select list using AJAX

Hello,
I saw Carl Backstrom and Scott Spendolini examples on how to use AJAX to populate a related item, based on a select list. What I'm looking for is the reversed angle.
I have a TextItem, and I want to generate a select list based on that TextItem, something like this:
select code, desc
from Table
where code like TextItem
Is it possible with AJAX? (in the current examples I gat lost in the on demand application process How, if possible, to render the select list using the HTP package.)
Greatly appreciate the help
Arie.

Carl,
I hope you can help with this, from reading the forum, you seem to have a lot of experience with AJAX and Application Express. I have found your examples within the forums and can not get them to work on my servers. I am on version 2, and a 10g database. I am attempting to place 4 select lists on a page. Each one (with exception from the first) will be dependent on the previous. To make is simple I have started with only 2 select lists. The first select list (p1_select1) is a list of departments. The second list (p1_select2) should populate with the users who belong to the department selected from p1_select1. I can not seem to get the second select list to load. I have attempted to follow your code as best I could, I can see on the page that it has created the xml data, however it just does not populate the second select list. Here is a summary of what I have.
Thanks for lookin.

Changing a select list using javascript

Hi all,
yesterday I had a doubt using apex_item.checkbox and how to change them using javascript:
Re: Passing a checkbox as a parameter to a javascript function
Today, I'm facing a similar problem, but with select lists. Here it goes. I have a report with apex_items, like this:
select
apex_item.checkbox(1,"ID",NULL,NULL,NULL,'f01_#ROWNUM#') " ",
apex_item.select_list_from_lov(2,"SW_STATUS",'F2010051_SET_STATUS','onChange="setItems(''f01_#ROWNUM#'',''f03_#ROWNUM@'')"','NO') sTATUS,
apex_item.select_list_from_lov(3,"REVISIO",'F2010051_SET_REVISIO',NULL,'NO','f04_#ROWNUM#') "REVISIO"
from Fx1_vThe javascript code is as follows:
<script type="text/javascript">
function setItems(cb,estat){
elem = $x(cb);
alert(elem.value);
$x(cb).checked = true;
elem2 = $x(estat);
alert(elem2.value);
</script>The idea is that everytime the item g_f02 (a select list) changes, calls the JS function with two parameters: a checkbox (g_f01) and another select list (g_f03). The function should change the items to a defined values. The checkbox changes ok thanks to the help I got yesterday, but I can't work with the third item (select list g_f03). When I try to show the value, it says "undefined".
how could I see the actual value of the select list LOV and change it to 1, for example?
Thank you very much, any help will be appreciated!!!

Hi,
Do you have typo in query?
Should it be
select
apex_item.checkbox(1,"ID",NULL,NULL,NULL,'f01_#ROWNUM#') " ",
apex_item.select_list_from_lov(2,"SW_STATUS",'F2010051_SET_STATUS','onChange="setItems(''f01_#ROWNUM#'',''f03_#ROWNUM#'')"','NO') sTATUS,
apex_item.select_list_from_lov(3,"REVISIO",'F2010051_SET_REVISIO',NULL,'NO','f04_#ROWNUM#') "REVISIO"
from Fx1_vAnd JavaScript
<script type="text/javascript">
function setItems(cb,estat){
elem = $x(cb);
alert(elem.value);
$x(cb).checked = true;
elem2 = $x(estat);
alert(elem2.value);
$s(elem2,1); // $s function is for changing item value
</script>Regards,

Can I create a multi-selection list using a dynamic list of values?

I'm reading section 19.7.3 from the dev guide - it explains how to create a selectOneListbox using a dynamic list of values. Is it possible to create a multi-select listbox from a dynamic list of values?
What I would like to do - I have a read-only view object with a hard-coded query - I would like to display the results of the query in a dropdown list box, or dropdown list box with boolean checkboxes, to allow the user to select multiple items from the list. How can I accomplish this?
thanks

Hi JavaX,
I don't know of any JSF components (at least not any ADF Faces components) that lets you do multiple selection in a drop-down. There is an af:selectManyListbox, but it does not render as a drop-down.

Color entries in select list

Say I have a dataset like (status_code,status_desc,color). A select list uses the code & desc but I would like to use the color of each status to be used as the background color for that entry. Patrick shows how to do this for a simple case right using the Element properties but how would this be done in my example?
I was thinking of using apex_util.json_from_sql to get the status_code & color in a Before Footer process and use Javascript to set the colors. But I couldn't figure out how to use the JSON as an associative array i.e. row[status_code] = color.
Comments? Thanks

Hello Vikas,
>> But when the page is submitted, Complete will be stored in session state and this is not one of the values returned by the LOV query …
Yes, sorry about that, I forgot I’m also using a Post Calculation Computation on the item, which calls a function that builds a matching value to the LOV. Something like:
select_list_color(:P1_SELECT);The body of this function is, of course, depends on the way/source to derive the status color. In my case, it looks like:
function "SELECT_LIST_COLOR" (
p_color_name in VARCHAR2
) return VARCHAR2
is
l_color_code varchar2(20) := '';
BEGIN
if p_color_name is not null then
    select code into l_color_code
    from mis_color_code
    where color = p_color_name;
end if;
return p_color_name || ':' || l_color_code;
END;
>> … so the LOV item needs to have "Show Extra Values" turned on
That’s not good enough as the Extra Value doesn’t include color code so the select list entry will not be colored (which defeat the original purpose).
>> Or maybe you have an after-submit computation to join the Complete and Green again so page rendering continues to work fine.
That’s also not good enough. First, I don’t want to impair the integrity/consistency of the session state. Secondly, if, for example, you are using ARF to populate the select list item, you’ll have the same problem, so after-submit computation is not enough.
The best solution I could think of is to use the Post Calculation Computation. So far it’s working very good.
Your solution, using AJAX, is also valid (and more importantly, it seems to work for you) however, in this specific scenario, where all the information is actually available to you pre-rendering the page, another trip to the database seems too costly (especially in my case, where some of the communication is over the Internet, using very crowded lines).

Marking an area on a picture by choosing at a selection list

Hello,
I was wondering if it is possible to mark a picture dynamic:
I have already a map and some COORDS - if you click on the shape, it links to another page:
<area shape="rect" coords="143,139,149,148" href="f?p=&APP_ID.:44:&SESSION.::::P44_FILE:20" alt="T 19">
Now I have a lot of this COORDS and it is very difficult to find them on the map. What I want to make is a select list or sth. like this, to choose the name of the area you want to find and it marks you this on the map with a cross.
Has anybody an idea how this could work or how this could be done??
Thank you soooo much,
LISA

Hi Lisa,
This may work (I don't have the stuff you have to set this up to test it!):
1 - Create a javascript array on your page, something like:
<script type="text/javascript">
var crosses = new Array (
new Array(0, 123, 345, "f?p=&APP_ID.:44:&SESSION.::::P44_FILE:1"),
new Array(1, 234, 567, "f?p=&APP_ID.:44:&SESSION.::::P44_FILE:2"),
etc
</script>This contains an ID (which would match the values on your select list), the top and left pixels where you want the cross to appear within the map area and the href value for the link
2 - On your page, create an A tag with an ID of "CROSS" and a style attribute of "display:none". The text between the opening and closing A tags would be your X
3 - Create a javascript function that can be called by your select list (your select list's definition should include an attribute of onclick="javascript:setCross();" to call it). The javascript function will then check the value of the select list (using $x('P1_LIST').value), find it in the crosses array, get the corresponding values and then set the position of the A tag and display it. Something like:
<script type="text/javascript">
function setCross()
var sel = $x('P1_LIST').value;
var t = crosses[sel][1]; // the top
var l = crosses[sel][2]; // the left
var h = crosses[sel][3]; // the href
var a = $x('CROSS');
var m = $x('MAP_ID');
a.style.position = "absolute";
a.style.zIndex = 99;
a.style.top = m.clientTop + t;
a.style.left = m.clientLeft + l;
a.href = h;
a.style.display = "block";
</script>The theory is that you can position a tag anywhere on the page using left and top settings - but you need to position within the map area, so you have to get its top and left as well. As the A tag would sit over your map, the user can no longer click on the map to trigger the link - the A tag, therefore, needs to have the link as well.
You may have to tweak/play with this to get it to work on your page. This is all theory, of course, but I think it should work ok.

Populate Select List from Checkboxes?

How do I populate a Select List from a checkbox set's checked display values and submitted values?
I'm guessing I need to parse the colon-delimited values, but I have no idea how to get the display values, or how to put all of that into the Select List.
Any ideas?
Cheers,
Ben

Hello,
Every select list item can be based on LOV. You can read more about it in here - http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28550/bldapp.htm#CHDFGFHI
If you are trying to populate a select list, using JavaScript, you can see a good example in here - http://htmldb.oracle.com/pls/otn/f?p=11933:37
Hope this helps,

Cascade select list tack few second to execute application process

Hi,
i have created some application proces fro cascading select list.
BUt when i select some value from select list then list is drpo down after click on slect value it show me drop down list value for few second .
i want when i click on selectted value then immediate relect this cascade list.
How can i resolve it.
Thanks

I am trying to guess from what I understood from your question.So correct me if I am wrong.You have set up cascading select list using ondemand process (onchange call process,retrun XML/JSON , parse the reyurn data and create/append option nodes to the child shortlist ) . The problem is that the child select list has the drop down available for a few second until the ajax HTTP request finishes completion.
Now you don't want any drop own to be available as soon as you select something.
If this is the case, add a line of code that disables the child select list as the first line of the called SJ function and enable it in the last line of the function
onchange="my_cascade_function()"
function my_cascade_function()
$x('SELECT_CHILD_ITEM').disabled=true;
//do ajax request here
//process retrun value, create select list
$x('SELECT_CHILD_ITEM').disabled=false;
}Does that help ?

Select list with bind variable does not work

Hi,
What can be wrong with a 'select list' with the a simple select
select omschrijving o, id i
from basiscodes b
where domein = 'OPTIES'
and b.id in
(select eo.basiscode_id from evenementen_opties eo
where eo.event_id = :P16_ID)
The :P16_ID has a value and should give result
But it does not work at all with 'select list'
Using the POPUP LOV (display discription, return key value) works nice
The select retuns less then 10 records

Hi Flavio,
As I explained, the P16_ID is an item of the master page (page 16)
In Page 18 where I want to reuse that value, the item is not there, but I use it to assign
P18_EVENT_ID with the value in P16_ID and that works fine.
In an after submit process, I do this :
declare
function get_pk return varchar2
is
begin
for c1 in (select EVENEMENT_INSCHRIJVING_SEQ.nextval next_val
from dual)
loop
return c1.next_val;
end loop;
end;
begin
:P18_ID := get_pk;
:P18_EVENT_ID := :P16_ID;
:P18_CREATIE_DT := TO_CHAR(SYSDATE,'DD-MM-YYYY HH24:MI:SS');
:P18_CREATIE_USER := APEX_APPLICATION.G_USER;
end;
The value P16_ID is there before I open page 18
I made a display item that displays the value P16_ID
If I change the LOV select in :
select b.omschrijving o, b.id i
from basiscodes b
, evenementen_opties eo
where b.domein = 'OPTIES'
and b.id = eo.basiscode_id
and eo.event_id = 16
then it returns the value I want : 1 record
You see, I'm a really new one in apex.

Select List (Parent/Child) LOV

I have the Easy Oracle HTML-DB book, they give an example of a
Parent Child Select List using a query.
Does anyone know how to apply the Parent/Child relationship with
a List of Value generated from a table.
Example
Parent Child
Car Pontiac
Car Buick
Car Cadillac
Car Nissan
Truck Tahoe
Truck Silverado
Truck F150
Truck Titan
The parent(s) in the above example are Car/Truck, the children are in the adjacent column.
Objective: When the parent "Car" is chosen, only the "Pontiac/Buick/Cadillac/Nissan" will be available, once the child is selected,
wish to submit to a empty table that can grow dynamically.
OS: Windows: XP
Oracle ver.: 10g
Apex ver.: Release 2

Hi,
are you just having one table storing all the values?
1) Create a "Select list with Submit"
2) Lov query would be something like
SELECT DISTINCT
       CAR_TYPE AS D
     , CAR_TYPE AS R
FROM WHATEVER_TABLEThe distinct is only because you have mixed your parent and child values in one table instead of having two separate tables with a FK from the child to the parent.
3) Create another "Select List"
4) Lov query would be something like
SELECT CAR AS D
     , CAR AS R
FROM WHATEVER_TABLE
WHERE CAR_TYPE = :P2_CAR_TYPE-> in the where clause you restricting the second lov with the value the user has selected in the first select list.
The first "Select List with Submit" will trigger a full page refresh when you select a car type. If you want to avoid that you can use the AJAX based "Cascading Lov" feature of my ApexLib Framework (see http://apex.oracle.com/pls/otn/f?p=33231:4 ) or search on the forum for "cascading lov ajax" for other similar solutions.

How to get the text boxes and select lists dynamically?

Hi,
I have a requirement such that I need to create the text boxes and select lists depending on the user input at the run time. It means that if the user requires four text boxes/select lists then I need to have 4 such thing. If the user need 6 then I need to have 6.
The design may be such that initially only one text box/select list will be available when the page launches. Then as ad when the user asks for more those will be available to the user accordingly.
regards,
Dipankar.

You can use Ajax to call textboxes and select list based on what user enters.
Otherwise make those items conditional and based on what user enters you can display textbox or select list.
You can call Single Textbox and Select List using Ajax for any number of conditions.

Chandra

Select List multiple values

All,
I am in urgent need of this requirement referencing/copying all selected multiple values in select List and putting them into text item/text-area separated by ","/comma delimiter.....any help
appreciated.
example:
select list
=======
aaaa
bbbb (selected)
cccc
dddd(selected)
ffffff
copied is:
bbbb, dddd

No worries, I've found a way.
You need to create a pl-sql function that generates the necessary HTML code that will render the select list using the selected="selected" attribute when the option value is selected.
This is an example of the expected HTML code for a multiple selection list:
<select name="favoritefood" id="favoritefood" multiple=true; size=4;>
<option value=1>Cheese</option>
<option value=2 selected="selected">Egg</option>
<option value=3>Cabbage</option>
<option value=4 selected="selected">Ham</option>
</select>
I created this function in order to find the matches within the saved code and the option value. And then include the selected="selected" string in the returned HTML code.
Finally, I'm using this function in the SQL query that generates a tabular report and I changed the column Display Attribute to "Standard Report Column". Then the report instead of showing the HTML code, will render it to a HTML item.

Thumbnail selections, events and selection lists

I'm experimenting with creating an external data file to track Bridge selections. I've come across two problems, one of which I have found a fix for, the other not.
If I obtain 'app.document.selections' following a 'select' event type, the list I get is actually the list prior to the latest selection. So if I had test1.jpg selected and switch to test2.jpg, app.document.selections[0] will be test1.jpg. The same applies to using 'deselect' that actual deselection does not show in the app.document.selections list when the event is triggered.
The fix for this is to use event type 'preview' which returns the latest selections at the moment you change the selection.
Unfortunately, preview does not update when you click when you deselect - and since deselect and select events both seem to come ahead of the updating of the selections list, using them does not work.
Any suggestions / ideas on this.
Andrew
Here is the code I am currently using:
onThumbnailEvent = function( event ){
if( event.object.constructor.name == "Thumbnail" ){
if( event.type == "preview" ) {
ah_CollectBridgeData();
return {handled:true};//stop processing event handlers
ah_writeData = function (tFile,tString) {
if (tFile.open('w')) {
if (tFile.write(tString)) tFile.close();
else throw ("Error saving file list\n" + tFile);
else throw ('Error, Data File Not Opened\n' + tFile);
ah_CollectBridgeData = function () {
var tFile = new File ('/c/Program Files/Adobe/Adobe Photoshop CS2/Presets/Scripts/nn-test3.dat');
var filestr = ah_fileThumbnailsToFilestr(app.document.selections);
ah_writeData(tFile,filestr);
ah_fileThumbnailsToFilestr = function( thumbnails ) {
var fileAr = new Array();
for ( var i = 0; i < thumbnails.length; i++ ) {
if(thumbnails[i].spec instanceof File) fileAr.push(thumbnails[ i ].spec);
return fileAr.toString();
// register the handler
allDocEventHandlers = { handler: onThumbnailEvent };
app.eventHandlers.push( allDocEventHandlers );

ugh, hadn't thot that thru yet on the deselect...
Looks like you get "n" deselects in a row.
Run this in ESTK, keep estk's console visible then select/deselect in bridge...
#target bridge
EventWatcher = {};
EventWatcher.lastEvent = "";
EventWatcher.eventCatcher = function( evt ) {
$.writeln( evt.type + " Event" );
if ( evt.type == "deselect" ) {
$.writeln( "Thumbnail Deselect: " + evt.object.path );
// debugger;
EventWatcher.lastEvent = evt;
return { handled: false };
app.eventHandlers.push( { handler: EventWatcher.eventCatcher } );
All the deselects (on a multiple deselect) happen in a row, and you're only interested in the last one, and you're not even interested in that. app.document.selections will be correct on the event (regardless of type) after the last deselect.
Hold off doing anything on a deselect until the event type changes.
if ( event.type = "deselect" ) {
myNamespace.loadedGun = true;
} else {
if ( myNamespace.loadedGun ) {
nowWriteMySelectionFile();
Since it's possible that you won't get another event for some time, you might want to setup a scheduled task that checks to see if the "gun is loaded", and if so to write the files.
Thanks for the kind words. I really enjoy working with everyone. It's a great break from head-down coding, and I learn something from just about every case.

Populate a select list based on sql query

I need to populate a select list using an sql query based on the value value I get from the previous page sent using link . How can I achieve this behaviour ? I tried giving select app_item_id a,app_item_id b from app_item_definition where app_id = :P11_APP_TDL_ID order by 1 in LOV, but it doesn't work . Please advice .

Okay, I just had the right idea and it's working well! Sorry for posting!
I return the name of the employee that has edited a dataset and simply add all others of the logged on department! Really easy! Should have thought of that before posting! ;-(
The correct code is select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter a, vt_tbl_punktdaten b where a.cnt_bearbeiter = b.int_bearbeiter and
