  I learned my lesson from the previous post on AJAX sl and I checked the process = its Ok, I added the warning to the js script, but change the first SL (f02) ends with nothing, not even a null value or a string of XML document ;/ I think I missed something with the onchange event string but I do not know what... ; /
  
  With respect,

  I think you are missing the closing parenthesis and double the quote on the end of your onchange
  Try

  select apex_item.hidden(1,PK) ||

• Cascading selection lists - does not

  I'm trying to implement the Ajax solution cascading select list of Denes Kubicek.
  [http://apex.oracle.com/pls/otn/f?p=31517:119]
  But something is wrong with my configuration.
  
  I created all the pieces, but for some reason it is like the
  Attribute of the HTML form element defined on my point P3_emp_dept is not called.
  OnChange = "get_select_list_xml1 (This, 'P3_emp_name');
  
  The two elements of P3_emp_dept and P3_emp_name selection list are defined as "Select generic list".
  For the Source, I tried the two "Always" and the "only when... sucks.
  Source type is defined as the "column of the database" P3_emp_dept and P3_emp_name respectively.
  
  When you fill out a blank page after choosing the P3_emp_dept, the P3_emp_name
  selection list is empty.
  
  When you change an existing record, if a different value is chosen for P3_emp_dept,
  the selection list for P3_emp_name still shows in the former Department employees.
  
  Any ideas?
  Thank you, Sue

  Sue:

  The second parameter to the function 'get_select_list_xml1' must be the name of the selection list that displays the names of the employees.
  Modify the call to this function for the 'Exchange' event handler declared to the selection list.

  onchange="get_select_list_xml1(this,'P3_EMP_NAME');"

• get the value of a selection list

  I made a request and on a page, I have a selection list filled from a list of values (made with a sql statement select).
  on the same page, I have a report made after a select statement.
  
  How can I did... when I select an item in the selection list in the report show me the item that is selected in the select list
  
  example:
  Select list: select name of EMP
  
  List of reports:
  Select * from emp;
  
  When I click on the selection list and chose a name of the employee in the report show me the first name, middle name, address and everything in emp.
  
  I tried to use emp.name = 'selectlist.value' and it gives me the invalid number.
  tried with the selection list with submit but still without work.
  
  can someone give me an ideea? How the current value of the selection list can be put in select condition of a statement or something to do all this?

  Andrei,

  Change your selection of P4_X list and make a list of selection with Submit. Now edit the report in the form query

  SELECT name, first name, address of the emp, whose name is nvl(:P4_X,name);

  I hope this helps.

  In step 5, he said the rest of the code if you are applying for an account. Do we need to add a lot of code to get success?
  
  Is there anyone who tries to do as did Mr. Kubicek?
  
  Thanks in advance. Good bye.

• Select list first value problem using AJAX

  Hello
  
  I've implemented the list of selection in AJAX by allusion to Denes Kubicek - http://apex.oracle.com/pls/otn/f?p=31517:119:3737449055187298:NO. I have only 2 selection lists. The AJAX functionality doesn't quite work for the first selected value in the list select a first. I get not all values in second SelectList when the first value is selected in the first SelectList. It works very well for the rest of the values in the first selection list. I kept a few warning messages to debug JavaScript. I think the problem is with the function below,
  
  get var = new htmldb_Get (null, html_GetElement('pFlowId').value,
  = States_In_County', 0);
  Get.Add ('F109_AJAX_COUNTY', html_GetElement (pThis) .value);
  gReturn = get.get ('XML');
  
  For the first value in the first list of Select, gReturn.getElementsByTagName("option").length; Returns 0.

• 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

• Newb AJAX - construction hyperlink from two selection lists

  Hi people,
  
  Would anyone familiar with care of AJAX to help out me? I am very new to AJAX, and I'm trying to set up a page that generates a URL hyperlink based on two input chooses. By example, if the first select statement was 'IT' and the second 'APPL' the URL to be returned would be
  
  
  http://Apex.Oracle.com/pls/OTN/f?p=28213:2:803955090371716:no:2:P2_SUPPORT_DEPT, P2_SUPPORT_TYPE:IT, APPL
  
  The reason for this is because I want an easy way for employees to create links in their email signatures that correspond to their assistance and group service. In this way, when a customer clicks the link in the signature of the employee these two selection lists is already selected for customer when they submit comments on this employee.

  Hello

  You had a few problems with your javascript code.
  The one that you just had a plain error (wrong number of media which has been lifted) and the error.

  You select AJAX were working properly, but then to get the other content, you tried pulling XML reuse and analysis and the other which is excessive. He needed just to get the snippet of text and push it into the page.

  Here is your http://apex.oracle.com/pls/otn/f?p=28213:4 working page

  and here is your new code

   function change_support_type(pThis,pSelect){
      var l_Return = null;
      var l_Select = $x(pSelect);
      var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=change_support_type_page_4',4);
      get.add('P4_SUPPORT_DEPT',pThis.value);
      gReturn = get.get('XML');
      if(gReturn && l_Select){
          var l_Count = gReturn.getElementsByTagName("option").length;
          l_Select.length = 0;
          for(var i=0;i;appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)}}get = null;}
  
  function appendToSelect(pSelect, pValue, pContent) {var l_Opt = document.createElement("option");l_Opt.value = pValue;if(document.all){/* why is ie different ask bill */pSelect.options.add(l_Opt);l_Opt.innerText = pContent;}else{l_Opt.appendChild(document.createTextNode(pContent));pSelect.appendChild(l_Opt);}
  
  }
  
  function show_url(pThis, pThat){ var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=show_url',4);get.add('P4_SUPPORT_DEPT',$v('P4_SUPPORT_DEPT')); get.add('P4_SUPPORT_TYPE',$v('P4_SUPPORT_TYPE')); gReturn = get.get();     $x('drop_content').innerHTML = gReturn;get = null;}
  
  You can read more about our Ajax framework here [http://apex.oracle.com/pls/otn/f?p=11933:63]
  
  Also when developing AJAX you should use Firefox with the Firebug addon , even if your building for an IE only environment, it makes debugging AJAX and javascript issues much easier.

• selection list loading using the ondemand/ajax process data

  Guys,

  Ive has a selection list that has a query default LOV (select jobname d, jobid r of the work) but now iam trying to create application processes to pass new values LOV (like select ename d, empno from emp by 1 r) replacing the previous lov when a button is clicked

  any idea please?

  Apex 4.2.x

  Kind regards

  fac586

  good idea to use the function in the pipeline, but I really want to use ondemand/ajax call here I don't mind spending extra energy so long as its feasible

  I never mentioned in pipeline functions.

  A dynamic LOV can be created as either a static SQL query:

  select ename l, empno v from emp order by 1
  

  or in the body of a function that returns a SQL query:

  declare
  
    lov_sql varchar2(4000);
  
  begin
  
    if :foo > :bar
    then
      lov_sql := 'select dname l, deptno v from dept order by 1'
    else
      lov_sql := 'select ename l, empno v from emp order by 1'
    end if;
  
    return lov_sql;
  
  end;
  

  This will allow you to create a dynamic data source for the LOV using some logic is required. LOV options can be modified using standard dynamic action of refreshment. There is no need to create an additional On demand process or write complex AJAX code. Use declarative when possible.

• Invalid results based on the select list

  Hello
  I've set up 4 LOVs cascading in a test application. They fill each value based on the value of the parent cascading with success. My example is based on the query Ajax Denes Kubicek - Section III - for example - http://apex.oracle.com/pls/otn/f?p=31517:135:1771969688591802:NO. But I use 4 Cascading Select list not 4 text fields. My problem is that I am not able to scroll through records using the previous and next unless I select all 4 list selection of waterfall to fill the data in the record. I would like to be able to select the 1st list select then click on the search button to fill in the data of the registration for the selected value. Then use the previous and next to scroll through the data in the record. This code allows selection of cascade 4 list to keep focus when the key search selected. But the correct data are not returned if I only select 1 list select value and then click on the search button.

  Hi Charles,

  OK - it works now.

  I made a few changes here and there. Basically, I defined by default for four '-1' lists and accounted for this through the page and processes. You had the wrong name for the last item in your function onLoad(), so I've changed that. Also notes that the question of the "closing date" must be formatted with a date MM/DD/YYYY formats to ensure that these are properly (the date of default real format came in the form DD-MON-AA, so you would have questions there if you don't stick to a single format). For each item, you can choose another value by default if it makes more sense for you, but you go through every place where the list is mentioned/used for updating the-1 for her to this new value.

  The processes themselves also tried to update the four lists as you go through the records. As the lists would not necessarily have all the values on them (you can click on search without making any selection, for example), I disabled these bits. However, you you should consider adding to the class section of THS page as new, so that the user can view all the information. The alternative would be to have all the lists display all the values unless otherwise filtered by their parent list - always feasible, but may be confused?

• How to set the default value in the select list to cascaded

  Hello
  I use Denes Kubicek cascade example list of selection http://htmldb.oracle.com/pls/otn/f?p=31517:119
  
  And I want to give cascading the selection list with a default value. So, anyway, I use this application process:
  
  < pre >
  BEGIN
  OWA_UTIL.mime_header ("text/xml", FALSE);
  HTP.p ('Cache-Control: non-cache');
  HTP.p ('Pragma: non-cache');
  OWA_UTIL.http_header_close;
  HTP.prn ("< select >");
  HTP.prn ("< option value ="' | 1 |) "" > ' | '- all employees-' | ' < / option > ");"
  
  FOR c IN (SELECT ename, empno
  WCP
  WHERE mgr =: cascading_selectlist_item_2)
  LOOP
  HTP.prn ("< option value ="' | c.empno |) '">' || c.Ename | ("< / option >");
  END LOOP;
  
  HTP.prn ("< / select >");
  END;
  < / pre >
  
  How can I select for example empno default 1000?
  Thanks in advance.
  Jacob

  Jakob,

  In this case, your default value is

  HTP.prn (')' || "- All employees - | '');

  However, you can set the default value in the loop as you want. You just say that is your default - first, second, third...

  In the list select ajax there's no submit and no calculation of values then I assuem your default is the punch one you wan to display when a selection list has been changed?

• How a select list to cascaded in a table?

  Hello

  I would like to know how to create a pick list cascading tabular.

  In the screenshot next, for example, when select "2081: Alice Fan", the next filed should watch only "ID: name of the element" belongs to Alice.

  

  Usually I do this simply for an article by implementing the SQL query and cascade LOV parent as follows.

  However, I can't find it in the form of tables?

  

  

  One can help with the solution?

  I hope that this can be done to reload partially after the first field had changed, but not to present an entire page.

  Thank you!

  Hi AliceFan-Oracle,

  Please see application 81653, page 2 (Test in the navigation menu).

  It's the ERT_TABLE_Item.

  If 'point ERT ID' is cascaded by ERT ID,

  When select "2221" ERT ID, it takes only the concerts "2521" and "2541" at the point of the ERT ID.

  When select "2222" ERT ID, it takes only the concerts '2561"in ERT item ID.

  ID ERT and ERT tabular item ID are columns 29th and 30th.

  Check your Application-> Page 2 81653 on your instance of apex.oracle.com. I implemented the LOV cascading using the solution of Jari.

  Reference: APEX Blog of Jari: Article Cascading select list in the form of

  Here are the steps how this is implemented:

  • Edited your Page attributes-> section JavaScript-> 'Function and Variable global statement' has added the following code:

  (function($){
  
  /*** Cascading select list ***/
  $.fn.htmldbCascade=function(parent,onDemand,options){
  
    options=$.extend({
     trigger       : false,
     extrVal       : false,
     nullShow      : false,
     nullValue     : "",
     nullDisplay   : "- Select -",
     disAlias      : "DIS",
     retAlias      : "RET",
     loadingTxt    : "Loading ...",
     loadingCss    : {"width":"80px"}
    },options);
  
    return this.each(function(i){
  
     var self=$(this);
     var lParent=$(parent).eq(i);
     var lSelfVal=self.val();
     if(!lSelfVal){lSelfVal="";};
  
     if(!lParent.data("htmldbCascade")){
      lParent.change(function(){
  
       var lParentVal=$v(this);
       if(!lParentVal){lParentVal="";};
  
       $.extend(options.loadingCss,{"height":self.parent().height()});
  
       self
        .hide()
        .empty()
        .parent()
        .find("div.ui-autocomplete-loading")
        .remove()
        .end()
        .append($("
  ",{"html":options.loadingTxt,"css":options.loadingCss})
        .addClass("ui-autocomplete-loading"));
  
       if(options.nullShow){
        appendOpt(self,options.nullDisplay,options.nullValue);
       };
  
       $.post("wwv_flow.show",{
        p_flow_id:"&APP_ID.",
        p_flow_step_id:"&APP_PAGE_ID.",
        p_instance:"&APP_SESSION.",
        p_request:"APPLICATION_PROCESS="+onDemand,
        x01:lParentVal
       },function(jd){
        var lExists=false;
        $.each(jd.row,function(i,d){
         if(d[options.retAlias]===lSelfVal){lExists=true;};
         appendOpt(self,d[options.disAlias],d[options.retAlias]);
        });
        if(options.extrVal&&!lExists){
         appendOpt(self,lSelfVal,lSelfVal);
        };
        self
         .val(lSelfVal)
         .show()
         .parent()
         .find("div.ui-autocomplete-loading")
         .remove();
        if(options.trigger){self.trigger(options.trigger);};
       },"json");
  
      }).data("htmldbCascade",true).trigger("change");
     }
    });
    /*** Append option ***/
    function appendOpt(pThis,pDis,pRet){
     pThis.append( $("",{"html":pDis,"value":pRet}) );
    };
  };
  
  })(apex.jQuery);
  

  • Edited your ERT_ITEM_ID column and added the following code to query LOV:

  SELECT NULL d,
         NULL r
  FROM   DUAL
  WHERE  1 = 2
  

  • Application G_TEMP element created in shared components-> section elements of enforcement with Protection of Session State"set to"Unrestricted ".
  • Created AJAX callback information Page at the request of GET_ERT_ITEM_ID process with the following code:

  DECLARE
    l_sql VARCHAR2(32700);
  BEGIN
    IF APEX_APPLICATION.G_x01 IS NOT NULL THEN
      APEX_UTIL.SET_SESSION_STATE('G_TEMP', APEX_APPLICATION.G_x01);
      l_sql := '
        SELECT ERT_ITEM_ID||'': ''||VENDOR_ID DIS,
               ERT_ITEM_ID RET
        FROM   ERT_TABLE_ITEM
        WHERE  ERT_ID = :G_TEMP
        ORDER BY 1
      ';
    APEX_UTIL.JSON_FROM_SQL(l_sql);
    ELSE
      HTP.prn('{"row":[]}');
    END IF;
    APEX_UTIL.SET_SESSION_STATE('G_TEMP', NULL);
  END;
  

  • Created the dynamic action named "Set LOV cascade after refresh and onload", with the following attributes:

  Event: After refresh

  Selection type: region

  Region: Update purchase order (15)

  Condition: No strings attached

  Action: Run the JavaScript Code

  Fire on loading the Page: Yes

  Code:

  $("[name=f30]").htmldbCascade(
  "[name=f29]",
  "GET_ERT_ITEM_ID",{
    nullShow:true,
    nullDisplay:"- Select -"
  });
  

  Assigned items: no

  • 'Action' button "ADD a line" changed "defined by the dynamic Action. Created another dynamic action named "Cascading select list Set for the new line" with the following attributes:

  Event: click on

  Selection type: button

  Region: ADD Row

  Condition: No strings attached

  Action: Run the JavaScript Code

  Fire on loading the Page: No.

  Code:

  apex.widget.tabular.addRow();
  $("[name=f30]:last").htmldbCascade(
  "[name=f29]:last",
  "GET_ERT_ITEM_ID",{
    nullShow:true,
    nullDisplay:"- Select -"
  });
  

  Assigned items: no

  Kind regards
