• Problem with the help of the $s javascript function to fill a page element

  Hello Oracle APEX community,
  
  I work on a page dashboard of exploration down and have been a problem when I try to fill a Page of text (hidden or not) element using javascript built in function $s.
  The feature works very well when the data is a number such as dept_id (even if the field type is varchar type). However, trying to pass what is a text the process fails, unless a value is hardcoded as parameter to the function. So, for example, I have a table with constituents by State counties. I would like to fill out (filter) a table based on when you click a bar for a State without having to submit the page. I use dynamic actions and built in javascript function in the SQL code for the graph to achieve; But even once, it works fine when I use a field varchar as the FIPS code (FIPS for Texas is "48"), but when I try to fill the page element by using the abbreviation of the State "TX" (new varchar), it fails.
  
  Here is an example of code that works:

  SELECT 'javascript:$s("P1_DEPTNO",'||d.deptno||')' LINK,
  d.dname LABEL,
  sum(e.SAL) sal
  FROM emp e, dept d
  where e.deptno = d.deptno
  group by 'javascript:$s("P1_DEPTNO",'||d.deptno||')', d.dname 

  And here is an example of code that does not work:

  SELECT 'javascript:$s("P1_DEPTNO",'||d.loc||')' LINK,
  d.dname LABEL,
  sum(e.SAL) sal
  FROM emp e, dept d
  where e.deptno = d.deptno
  group by 'javascript:$s("P1_DEPTNO",'||d.loc||')', d.dname 

  However, when I hard code a value the script text works:

  SELECT 'javascript:$s("P1_DEPTNO","BOSTON")' LINK,
  d.dname LABEL,
  sum(e.SAL) sal
  FROM emp e, dept d
  where e.deptno = d.deptno
  group by 'javascript:$s("P1_DEPTNO","BOSTON")', d.dname
  ORDER BY d.dname 

  I encounter this problem on several versions of the APEX: (4.0.2.00.07 - local installation) and (4.1.0.00.28 - apex.oracle.com)
  
  Does anyone know of this problem and how to solve? I have looked for the parameters of the element of the page itself and can not understand.
  I rewrote my sql to use the fields of value of my tables instead, but I have a few objects on the page that will really depend on the data of base characters instead.
  
  Thank you

  In your javascript that you generate, surround your value with quotes and it will then should always work with the numbers and strings (your channels are probably interpreted as variable names and that they do not exist when running, so slip out).

  Example:

  SELECT 'javascript:$s("P1_DEPTNO","'||d.loc||'")' LINK,

  Hi Amelia,.

  Through application process only we can able to save the page element value in session state? is there another way?
  Since my requirement is like I need to display footer text in all the pages, I have the version number included in this text, so I created a table and my intention to create an item and passing the point value for all other pages and see that point value & P26_NO. in the text. Version number is dynamic, it will change at each deployment.
  Is another way simple, other than my approach?

  Thank you best regards &,.

  You should use point demand for it and an application process to fill

    APEX_UTIL.SET_SESSION_STATE('APP_ITEM_NAME','myvalue');

• Can not set a value by the executed dynamic action on the page element "selection list."

  I created an agenda of the page 'list of selection' and I want to when I change a value in another element of the page set only 'screen '.

  I created a dynamic action on the page element "selection list" for this.

  These are the dynamic action attribute:

  The ' Action Page when the changed value "attribute of the element of 'list of selection' = 'None', and when I run form the dynamic action run and set the value for once and do not update the value according to the change in the article"list of selection. "

  Note: when I change the previous attribute of 'Redirect and set', dynamic action run and properly value, but the value was hidden soon

  I want to value when the value of change of select list according to this change successfully.

  Please, advice me,

  Best regards

  Mustafa Ezzat

  Hello

  you set the value of the 'Page elements to submit' to P29_PURCHASE_ORDER?

  Then, the SQL statement would use the current selected value.

  This is the help text says: "specify a list separated by commas of the elements of the page that will be submitted to the server and therefore available for use in your"SQL statement"," PL/SQL Expression"or"Body of the PL/SQL function".»

• Display the values of the Page element in HTML table

  Hi all
  
  could you please help me with the below? I want to have a table in the HTML area and to display in the table of elements of the Page of the page.
  
  I got the code like this:
  {
  < table >
  < tr > < td > & P1_ECEMEA_ASSISTANCE < table > < /tr >
  < tr > < td > & P1_ECEMEA_WIP < table > < /tr >
  < /table >
  }
  It shows the element of the Page names in the form of text, not the values.
  
  However, this code without the tags table:
  {
  ECEMEA request for Assistance of the CQT: & P1_ECEMEA_ASSISTANCE.
  ECEMEA CQT Work in Progress: & P1_ECEMEA_WIP.
  }
  Works and Page element values are displayed.
  
  Is it possible to display the values of the Page element in the HTML table at all or should I use a different method to show the values in a table? The above is only an excerpt of the code. I need to display about 30 items in Page, put in shape in a table with headers.
  
  Please let me know what kind of region is the best to use, or if I have to use only a few symbols of escape in the table code...

  Depends on what is the type of page element - for text/no Select something like:

  function setValue(){

  For a select element, something like this:

• Default method of workflow activity is not called when the Page refreshes

  Basically, try to call a script function java front page of fragments of the charges.

  INSTALLATION PROGRAM:

  Jdev 12 c

  TF defined with a default activity that invokes a page fragment.

  The activity of default method calls a method to support bean which inturn calls the method init java script before the fragment on the page doesn't load.

  This TF is in a container jsf page.

  During the loading of the page containing the first activity of the method is called and js function triggers and then fragments of charges which is the desired behavior.

  PROBLEM:

  When I refresh the page by pressing F5 or by running the page again on the same window of the browser activity method default IS NOT gets called which inturn will not trigger the js call.

  But when I run the same page again in a different window it works and then subsequent updates or page load activity IS NOT of default method is called.

  If it is not provided? The default activity is called when the workflow is updated.

• LOVs using cascading on the Page elements with values exceeding 4000 characters

  A few days ago, I asked a question on the community, but it turned out that there was something wrong with my account and they have removed the item, so I'll just post the solution I found here now:

  Well, I found a way to use LOVs cascading on page elements with values exceeding 4000 characters:

  Let's say I have a shuttle named P1_ORGANISATIE with "List of values" box, a dynamic LOV named "Source: lists of values Query" containing the value:

  Select NAAM as display_value, ID like return_value

  of NINEHAM

  order by 1

  If the number of records-NINEHAM is insufficient, the length of the value of P1_ORGANISATIE, which is a list of concatenated with colon separated digital ID, can exceed 4000 characters.

  Now, suppose I have a list of selection called P1_TEST that is connected through "List of values"-> "Cascading LOV Parent article (s)" with P1_ORGANISATIE, using a named LOV dynamic with "Source: lists of values Query" containing:

  Select distinct TST. NAAM as display_value, TST.ID as return_value

  of the OTE NINEHAM

  Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

  Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

  Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

  Join TESTEN TST ON (TST.ID = RDT. TST_ID)

  where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | :'') > 0

  order by 1

  In this case, when P1_ORGANISATIE exceeds 3998 characters, you'll get an "ORA-01704: string literal too long"-error and the P1_TEST will show an element called "undefined".

  A way around this is possible because for a named LOV, you can use a "function that returns a sql query" instead of a simple sql query. In other words, we can apply in the context of PL/SQL and thus have maximum for expressions of 32767 instead of 4000 characters. In addition, it is possible to use the two APEX_UTIL. STRING_TO_TABLE and APEX_COLLECTION.

  Setting "Source: lists of query values" on the LOV appointed to P1_TEST with the following code will work:

  DECLARE

  l_selected APEX_APPLICATION_GLOBAL. VC_ARR2;

  l_qry varchar2 (32767): =.

  "Select distinct TST. NAAM as display_value, TST.ID as return_value

  of the OTE NINEHAM

  Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

  Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

  Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

  Join TESTEN TST ON (TST.ID = RDT. TST_ID)

  $1

  order by 1';

  BEGIN

  IF: P1_ORGANISATIE IS NULL

  OR LENGTH(:P1_ORGANISATIE) < = 4000

  THEN RETURN

  Replace (l_qry

  ,'$1'

  ,' where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | :'') > 0'

  );

  ON THE OTHER

  l_selected: = APEX_UTIL. STRING_TO_TABLE(:P1_ORGANISATIE);

  APEX_COLLECTION. CREATE_OR_TRUNCATE_COLLECTION (p_collection_name = > 'ORGANISATIE_COLLECTIE');

  FOR id IN 1.l_selected.count

  LOOP

  APEX_COLLECTION.add_member (p_collection_name = > 'ORGANISATIE_COLLECTIE')

  , p_n001 = > to_number (l_selected (id))

  );

  END LOOP;

  RETURN

  Replace (l_qry

  ,'$1'

  ,'join apex_collections ON APC (APC. COLLECTION_NAME = "ORGANISATIE_COLLECTIE" AND APC. N001 = OTE.ID)"

  );

  END IF;

  END;

• Reading of the Page element only from option buttons

  Apex 4.2

  I have a page apex with a group of radio buttons and a text box. I try to have a user click on one of the radio buttons and the text box is read-only, depending on which is selected.

  P101_RAD_BTNS

  P101_TXT_BOX

  There are two buttons in the radio button group: active and inactive. If the user clicks on the 'Inactive' button, the text box (P101_TXT_BOX) becomes read-only. If the user then clicks on the "Active" button, the bbox text is no longer read-only.

  I tried to do this with a dynamic action, but it's not exaclty an option "read only". I tried to use "enable / disable", but it did not work. I thought to try some kind of javascript function, but I'm not sure of the syntax.

  Any help on this would be greatly appreciated. Thanks in advance.

  Assuming that the values of your P101_RAD_BTNS are for Active and N for inactive, I would call a JavaScript function custom event onchange dynamic Action on P101_RAD_BTNS.

  When:

  Event: change

  Selection type: item (s)

  Product (s): P101_RAD_BTNS

  Condition: No strings attached

  Action: Run the JavaScript Code

  Fire on loading the Page: false

  Code: f_setReadOnly (this.triggeringElement.id);

  function f_setReadOnly(pID){
    $val = $v(pID);
    if ($val == 'N') {
      $("#P101_TXT_BOX").attr("readonly",true).css("background-color", "#d9d9d9");
    } else {
      $("#P101_TXT_BOX").attr("readonly",false).css("background-color", "");
    }
  }

• Checking the referential integrity of a form before the presentation of the Page element

  Hi, OTN,.
  
  I have a form on a table with multiple columns, some of which are foreign keys to other tables. Rather than validate the columns for referential integrity when the user inserts/changes in shape, I would use a dynamic action to attract the attention of the user with a javascript alert() when the user loses focus of the element. After a user enters a value into the text box and moves to the next item, I want to be able to query the table, check the existence of the value of the user and issue a javascript alert() if there is no match.
  
  What is the best way to go about this?
  
  I created a dynamic action-to run PL/SQL code on one of the elements of the page, with a code similar to the following:
  
  DECLARE
  rf_check varchar2 (30);
  BEGIN
  SELECT col1 INTO table_a FROM rf_check
  WHERE col1 =: P1_ITEM_FK;
  EXCEPTION
  WHEN NO_DATA_FOUND THEN
  HTP.p ("< script type =" text/javascript"> ');
  HTP.p ("alert ("ERROR");");
  HTP.p ("< /script >" ");
  END;
  
  I could not get the dynamic action of delivering javascript. Any thoughts?
  
  Thank you

  I have to admit that I've never tried, but I would be surprised if Javascript back via statements made htp.p that they are actually executed by the browser.

  I would do something like that, by a dynamic action that calls an application process. The PL/SQL procedure request would return via htp.p OK or ERROR. From this result, the javascript would determine to issue the alert. Something like the following (not fully tested):

  Javascipt
  
   var get = new htmldb_Get(null,html_GetElement('pFlowId').value, 'APPLICATION_PROCESS=FK_CHECK',0);
   var fk_check = get.get();
  
   if (fk_check=='ERROR')
    {
     alert('ERROR');
    }
  
  Application Process FK_CHECK
  
  DECLARE
    rf_check varchar2(30);
  BEGIN
    SELECT col1 INTO rf_check FROM table_a
    WHERE col1 = :P1_ITEM_FK;
    HTP.p('OK');
  EXCEPTION
    WHEN NO_DATA_FOUND THEN
       HTP.p('ERROR');

• Assign value APEX URL of the page to the redirect of the page element

  Hello
  I have the following hard coded URL routing traffic on page 10:
  href = "f? p = & APP_ID.:10: & SESSION. ::: 10 : »
  
  However, now I have logic to determine the button of the page which should route traffic and I'm storing in a Page element called P6_PAGE_ROUTE (the value is 10 or 23). How can I get the URL to direct traffic based on the value in P6_PAGE_ROUTE? I did some research and I've tried using the & P6_PAGE_ROUTE. but it does not work:
  
  href = "f? p = & APP_ID.: & P6_PAGE_ROUTE. : & SESSION. : & P6_PAGE_ROUTE. : »
  
  Thanks in advance for any help!

  URL addresses by passing the values generally have this format:

  href = "f? p = & APP_ID.: & P6_PAGE_ROUTE. : & SESSION. : ITEM1, ITEM2, ITEM3:VALUE1, VALUE2, VALU3

  Where,
  Question 1 has value 1
  question 2 has value 2
  and point 3A of value 3

  So the stuff LHS of the *: * must be the name of a page element

  + PS: Ensure no space after the comma as its URL. I fell for the first time and it is difficult to meet. +

• Value of the page element in the APA process not maintained after the send this page

  Hello - I have a sequence of events that goes like this:
  
  (1) region 0 REG_1 Page is rendered before footer
  -REG_1 region uses javascript / AJAX to call App process PROC_1
  -PROC_1 defines Page1 item PAGE1_MESSAGE for X
  -After that PROC_1 runs correctly, REG_1 don't doSubmit()
  
  (2) region 0 REG_2 Page is rendered before footer; in this case
  After the page sent by REG_1. (Requirements to ensure that)
  REG_1 has not yet reached)
  -REG_2 region shows an alert PAGE1_MESSAGE (= X).
  -REG_2 region uses javascript / AJAX to call App process PROC_2
  -PROC_2 sets page 1 point PAGE1_MESSAGE to Y
  -PROC_2 sets point Application DEBUG to PAGE1_MESSAGE (this is for debugging)
  -PROC_2 defines the point of Application APP_MESSAGE to Y (this is also for debugging)
  -After that PROC_2 runs correctly, REG_2 don't doSubmit()
  
  (3) after that REG_2 sent the page, here's what I have:
  -Point application APP_MESSAGE = y. good. That's what it has been for PROC_2.
  -Point Page 1 PAGE1_MESSAGE is bad. X. That's what he has been put to in PROC_1.
  -Point application DEBUG = y. good. This shows at least that PAGE1_MESSAGE was
  the value Y in PROC_2... but for some reason this value is not be kept
  After the application process is running.
  -There's that several other elements of the application located in PROC_2, and they are all correct.
  
  
  Any ideas as to why this is happening? It seems like it should be
  quite simple: set the value, send page, the value must be that
  I put it.
  
  Thank you

  Hello

  Exhibition (doesnot save session state), I am not changing who is P1_MESSAGE_1.

  Why does that matter? Why does the hidden item behave differently?
  

  Yes, Hidden Items by usually default state saves. But this isn't the problem in this case because I had changed the item to display only (state saved) and that did not help. Finally back in doesnot save state.

  Try to replace alert (ajaxResponse); with the lines below

  $s('P1_MESSAGE_1',ajaxResponse);
  alert($v('P1_MESSAGE_1'));
  

  Maybe the session state is defined (server), but the value in the DOM HTML (browser) to P1_MESSAGE_1 is not defined. If adding the line above works then the hypothesis is correct.

  And I see that you made the source "static" assignment ...
  

  Yes, I made this change, because it was a reference in itself I think it was redundant. And I had to correct what I thought is not just before debugging. Which cannot be linked to the problem though.

  Kind regards
