• Using AJAX code for the conditional selection list.

• Dynamic action in two selection list

  Hi all
  
  I created two select lists.one is parent of other child.
  
  I can get the child list correctly from the article values parent lov cascading
  
  For example: the company name of parent element values: x, y, z, etc.
  
  x with 3 customers say a, b, c
  
  There is no customer for y
  
  z with 2 customers say e
  
  now, I want to hide the element of the child when the parent having no child.
  
  Now when I select 'y' for the example above, I would like to hide the child element.
  
  How can I do?

  Hello

  You can do the following:
  1. create a hidden page element, say PX_HIDE_SHOW_FLG
  2. create a dynamic Action of type 'Set value' on the element parent to update PX_HIDE_SHOW_FLG. You can choose the "value Type" as "body of the PL/SQL function. The code in the function must return "Y" or "n" based on logic (count the number of children under the selected parent). You can trigger this DA on 'change' of the parent element.
  3. now, create another DA on PX_HIDE_SHOW_FLG to hide and show the child LOV article based on its value. For example, if value (of the page hidden item) = 'Y', and then hide, another show.

  Thank you

• Two Select lists with Submit single page branching to different page each?

  Hi all
  
  I have a page (No. 1) with two 'select list with Submit"(A and B). This page contains also two branches defined. I want to realize that the first list selection with present (A) would always use the first branching (at page n ° 2) and the select list a second with the submit (B) would use the second fork (at page no. 3).
  
  How can I achieve this? Y at - it a tutorial describing lists of selection and the ramifications?
  
  Thank you for your time.
  
  Daniel

  When the selection list submits the page, the value of "motion" is the name of the selection list item. So all you need to do is add a condition to each Directorate-General: Request = Expression 1 and enter the name of the element (top) in the field of 1 the condition Expression.

  Hello

  You have the following items in the pl/sql code of DA:

  begin
  select parent_id, child_id
   into :p1_parent, :p1_child
  from holder
  where parent_id = 1;
  end;
  

  You have the following in the query LOV's P1_CHILD:

  select col2 d, col1 r
  from child
  where col3 = :p1_parent
  

  P1_parent = 1, the LOV query returns 2 rows - DUNDEE and GLASGOW. The list of selection, therefore, cannot set a value. I changed the order of the day of the P1_CHILD page for a multiple-selection list and it works fine now.

• Javascript-based dynamic action and display the value of (!) from the selection list

  Hello
  
  I'm not a jQuery guru (yet).
  Can someone show me how to turn on or off an ITEM on a form based on the value display of a selection list (usually I have dynamic lists, so I don't 'know' even internal values)
  
  I created a simple demo in which you can (if you want to) show me how it works.
  
  Workspace: 6POOLRULES
  User: demo01
  Password: demo
  Application: 30851 (Drone)
  
  The idea is to
  * Disable/hide the "Id other Description" If the ' Id Type (display value!) is 'Passport' or 'license '.
  * activate/display the Description of the 'other' Id if the ' Id Type (display value!) is "other".
  
  
  I think that it should be dynamic action based on javascript/jQuery. But what would this jQuery selector should look like?

  Hello

  OK, I changed the dynamic action to use Jquery and get text from the value. The only thing I changed is in the section WHEN.

• Slight problem of AJAX selection list, I hope...

  I probably looked at all the examples that uses AJAX to fill selection lists that are out there and eventually got a job almost completely.
  
  In my application, I use a form on page 23 to create a folder and then also use a form on page 22 to update a record. Two of these pages, I have 2 selection lists that use AJAX to complete each other. On my page of form creation, these two select lists display properly and correctly submit a report page.
  
  Now, when I click on the document I just create the homepage, I get redirected to the update (page 22) page where I just submit all items are displayed correctly except the second selection list. The second selection list displays the correct list of the elements in the selection list, not the one I had just chosen. What is shown is the first option in the selection list, no matter what I had selected when I created the folder. Always the first option display anything in my code?

  Hello

  There are a number of issues here:

  1. remember that creation and editing features are on TWO different pages - when you refer to "the page is not save...". ' is in fact another page
  2. in the CHART table, you have an ID column AND a column RECNUM. You use the RECNUM column in the report link. In the CHART table, there are plenty of duplicates in the column RECNUM, which made it impossible for me to test - whenever I've created a new record that he got the same RECNUM value as an existing record, and I couldn't change then my new record as the process of "search...". ' incorrect 'more than one folder. You must use the ID column in the link, because it is unique
  3. on the selection of CAUSE list, you had a few items in quotes - I have no idea why. It was actually a good deal to do for your original problem. During the construction of the selection list, the value of the CASE is used as the VALUE attribute on the OPTION tag by enclosing it in quotes. What were you end up with is: < OPTION VALUE = '"sometext" ' > 'etc' < / OPTION >. The VALUE is, therefore, ""-an empty string. I removed the quotes from the data
  4. more importantly, as the CAUSE table made a unique ID column, this should be used as a return value for the list and therefore, the value stored on the CARD table. If you do this, you use the quotation marks if they are in some cases

  Hello

  It's actually the process code that is incorrect. It should be:

  BEGIN
  OWA_UTIL.mime_header('text/xml', FALSE);
  HTP.p('Cache-Control: no-cache');
  HTP.p('Pragma: no-cache');
  OWA_UTIL.http_header_close;
  HTP.prn('');
  HTP.prn('-All Managers-');
  FOR c IN (SELECT ENAME, EMPNO FROM EMP WHERE DEPTNO = :CASCADING_SELECTLIST_ITEM_1) LOOP
   HTP.prn('' || c.ENAME || '');
  END LOOP;
  HTP.prn('');
  END;
  

  The original code was "d SELECT ename, empno FROM EMP r... ». Therefore, the available fields in the loop are 'd' and 'r' not 'ename' and 'empno '. I have changed the above to delete 'd' and 'r '.

• How do the default editing a selection list after a change in another list of selection is made (not in cascade LOV).

  Hello

  I searched for the answer for a while now, but could not find a solution to my problem. It's a rather trivial issue, but after dealing with more urgent problems, I stuck with it and I can't move forward I use Apex 4.2.1

  OK, lets start with a description.

  I have two selection lists. After making a choice in the first, I would like to than the second value to change. It is not cascade LOV case, however, at least I don't.

  Let me give you an example. Suppose we have a table with name and default to the occupation.

  Name	By default occupancy
  John	Doctor
  Mark	Firefighter
  George	Firefighter
  Tom	Concierge

  End user first selects the name in the first list, then the occupation of another. It's perhaps not clearly in the example given, but the order of the questions.

  What I want is to force a change in the second value in the list after a choice in the first. So after the name is chosen, the occupation should switch to the default.

  The assignment is the most typical, but not the only one. So I want the end user to be able to change the occupation if necessary. Tom of sense is not to be janiotor, it can be whoever he wants this is why it is not cascade LOV problem.

  I tried with dynamic action - definition of value and then refresh. It works when the second selection list is the text field. I can't find a way to make it work with another selection list.

  Hope you can help.

  Concerning

  AEMs salvation,

  What I wanted with display and return value, you usually have a list of selection like this query:

  SELECT occupation d, occp_id r

  OF professions

  If your return value is an identifier. To use the text as return value is rather rare. Where my question, because obviously you must select the return value in your query, NOT the display value.

  So let me explain what is a set value. It takes the value of the server by using your query and AJAX in the background, then uses Javascript to set the value of the item in the browser.

  At this point your selection list still has the OLD value in the session. Then, you do a refresh and the element uses the old value, and it seems that nothing happens.

  So solution:

  -clear default values, you don't need those

  -get rid of refresh it in your DA

  Kind regards

• Cascading - HELP selection lists

  I still missed something in the samples I've seen on the internet at cascading selection lists
  I just need a selection list to determine the choice of another selection list, use simple terms.
  Thanks for your help. Please need as soon as possible.

  Hello

  OK - first of all you must have an item hidden on page 2 that will receive the country code (I'll stick with my example, if that's ok)-say P2_COUNTRY_CODE.

  Now create two selection lists - say P2_STATE_CODE and P2_CITY_CODE.

  It helps if you check that the P2_STATE_CODE list is defined with a default value to ensure that the list can be filtered properly. Create a calculation, to run in the point of process "Before Header" and the conditional on P2_STATE_CODE is null (Type of Condition: the point in 1 Expression is NULL;) Expression 1: P2_STATE_CODE). The value of a "static allocation" of something that will not appear in the list (for example, ZZ for strings) or - 1 for numerical values. You can do this on the list of cities as well if you wish. The two lists must be defined to display null values and have something like - Select - like display null text.

  Your list of States should be created as a Select list with Submit with a list of values based on a SQL statement:

  SELECT STATE_NAME d, STATE_CODE r FROM STATES WHERE COUNTRY_CODE = :P2_COUNTRY_CODE
  

  Your list of cities is a list of select normal with a list of values based on a SQL statement:

  SELECT CITY_NAME d, CITY_CODE r FROM CITIES
  WHERE COUNTRY_CODE = :P2_COUNTRY_CODE
  AND (:P2_STATE_CODE = 'ZZ' OR STATE_CODE = :P2_STATE_CODE)
  

  Now, when the user selects a country from page 1, the country code is spent in P2_COUNTRY_CODE before the loading of page 2. The default values for P2_STATE_CODE and P2_CITY_CODE are defined and the lists are generated - cities list will display all cities for the country selected as the list of States shows only the default value of ZZ and cela "corresponds to" all cities of the country. Then, when the user selects an item in the list of the States, the page is sent and the value of P2_STATE_CODE is updated in the session. As the list of cities is based on this value, when the page is reloaded, it will be updated to filter based on the P2_COUNTRY_CODE and P2_STATE_CODE values.

  The only thing you need to ensure is that P2_STATE_CODE and P2_CITY_CODE are deleted from the cache when you have more page - you can do in the branch back to page 1.

• Selection list cascading in the dialogue window

  Hello

  I'm developing in Apex 4.2.5.

  I have an Apex with a classic report region, in which a link edit page opens a dialog window (in the same page apex) to edit the selected line. The same dialog window is used to create a new line. The dialog window contains a cascading pick list. Two selection lists are defined to display NULL values and correctly fill in mode 'create '. My problem is that mode "Modify" the list of the second selection is not good value. The second selection list contains it however the right subset of values according to the parent, select the list and therefore don't does not contain the correct value, but it is not selected.

  I use a javascript function to fill in the fields in the dialog.

  ....

  $s ("P3_EVENT_TYPE", arguments [1]);

  $s ("P3_EVENT_SUBTYPE", [2] arguments);

  ....

  Then the display of the dialog window

  openDialog ('editEvent');

  
  

  The population of P3_EVENT_SUBTYPE list seems to happen but sometime after that all the fields in the dialog were assigned and the dialogue window displays.

  I see that I need to somehow update the list of selection in cascade, P3_EVENT_SUBTYPE, before assigning the value. My problem is how can I do this in the same javascript function?

  Kind regards

  Derek

  Eventually answered my own question-

  I created a hidden field in which to store the value of the event subtype.

  Created a dynamic of Action, after refresh of affected P3_EVENT_SUBTYPE subtype value = hidden field event.
