Call javascript application process

• Pass the parameter to the javascript application process

  I'm trying to pass a parameter to an application process from javascript and don't know how to do this. What I want to accomplish is to create checkboxes to delete several records at once. Before these records can be deleted, I need to make sure that the resource_type_id is not used. To do this, I call a javascript function with an onchange event that calls an application process to perform a database search. I have included the code to create the boxes and the JavaScript below. I am new to APEX, so there may be a way easier and better to do. Any help or suggestion about a better way to proceed would be appreciated.
  
  Thank you!

• Application process JavaScript

  Hello
  
  I want to run a JavaScript application process to update a table.

  'APPLICATION_PROCESS is update_rep_seq',

• The call for a process of application using JS by a button

  Hello
  
  I need to create a button that deletes the entire table All_References lines.
  
  I have created a new process of shared components "Delete_All_References" call, then set it to run on demand.
  
  PL/SQL block:
  
  Begin
  Delete from All_References;
  End;
  /
  
  In the HTML header of the page on which lies the button 'Remove all references' or P13_DeleteAllReferences, I entered in the following:
  
  < script language "JavaScript" type = "text/javascript" >
  function Delete_All_References()
  < /script >
  
  I have then entered the settings button, set the action to "defined by dinamic action", then added onchang = "javascript:Delete_All_References();" "in HTML table cell attributes.
  
  According to most of the tutorials when I click the button remove all the button of refereneces, my table should now get clear but it doesn't.
  
  Can you guys please help?
  
  Thank you and best regards,
  Diez

  The onchange event will work fine. Change the button back to a normal button instead of linking to a dynamic Action for now.

  The only other thing I see which can cause a problem is your call to the method itself.

  OnChange = "JavaScript:Delete_All_References();" »

  Need to replace...

  OnChange = "JavaScript:delete_all_references();" »

  The called javascript method is case-sensitive.

  Let me know if it suits it.

  What exactly is the point of this? The result of each process on request will probably be different, so as well as use the "dynamic" process, the function must also manage the value returned by the callback dynamically, which it does not currently appear to support.

  Always advanced postal code using the functionality of the syntax highlighted in the editor.

  
  

  function updateEmp(p_proc, p_empno) {
  
      var v_value = document.getElementById(p_empno).value;

        // do something here
          alert('tested this value = ' + v_value );
        }
    });
  }
  

  but when I hardcode the process name directly as below, it works.

  , p_request: ' "APPLICATION_PROCESS = OnDemandx"

  so, what could be the problem here?

  Line 15: v_proc a string value is not a literal and so should not be enclosed in quotes:

  function updateEmp(p_proc, p_empno) {
  
      var v_value = document.getElementById(p_empno).value;
      var v_proc =  'APPLICATION_PROCESS=' + p_proc;

  Using the apex.server.process API would be clearer and involve a lot less typing.

• To access the settings of ajax in the application process

  Hello

  I have an ajax call, submitting a parameter called cBoxKey.

     var get = new
     htmldb_Get(null,$v('pFlowId').value,'APPLICATION_PROCESS=TrackRows',0);
     get.add('cBoxKey','NOTREQUIRED');
    get.get();
  
  

  In the application process I can access the parameter 'cBoxKey' like below;

  declare
      l_checkBoxKey  varchar2(4000);  
  begin
      --
      -- Get the value of the global which will be set in JavaScript
      --
      l_checkBoxKey := wwv_flow.g_cBoxKey;
  
  

  However, this does not seem to work because when I replace

  l_checkBoxKey := wwv_flow.g_cBoxKey;
  
  

  with

  l_checkBoxKey := 'NOTREQUIRED';
  
  

  The application process is called and produces results (through the ajax call).

  In my view, that the question is how access the "cBoxKey" parameter in the application process.

  Any ideas on what could be wrong.

  Thank you.

  Hello

  I check any specification of package APEX version wwv_flow, there is no variable of g_cBoxKey.

  If you have idea there?

  Change your JavaScript for

  var get = new
  htmldb_Get(null,$v('pFlowId').value,'APPLICATION_PROCESS=TrackRows',0);
  get.addParam('x01','NOTREQUIRED');
  get.get();
  

  And then access process on demand as

  l_checkBoxKey := APEX_APPLICATION.g_x01;

• in IE progress bar problem with on call for application

  I have several on the enforcement of the application process that I have called from javascript. The application process call pl/sql procedures in turn. Some of the procedures can take up to 10 seconds to complete, and while they are running, the screen just to freeze so that the user does not know that they are actually running. So, I would add some kind of a progression or Hourglass bar or an indication that things are moving.
  
  So I found the instructions of Re: hourglass display when the Page is processing . This works fine in Firefox but not in Internet Explorer.
  
  My footer text:
  
  < Style > #AjaxLoading {padding: 5px; do-size: 18px; width: 200px; text-align: center; left: 50%; top: 20%; position: absolute; border: 2px solid #666; background-color: #FFF ;}}
  < / style >
  < div id = "AjaxLoading" style = "" display: none; ">..." Treatment...
  < img src = "" #IMAGE_PREFIX #processing3.gif "id ="wait"/ >"
  < / div >
  
  My javascript:
  
  function create_invoice (pMilestoneNumber) {}
  Okay var = ("are confirm you sure you want to charge this invoice?");
  get var = new htmldb_Get (null, $v ('pFlowId'), 'APPLICATION_PROCESS is P110_CREATE_INVOICE', $v ('pFlowStepId'));

  gReturn = get.get ();
  Alert (gReturn);
  get = null;
  doSubmit();
  }
  
  In Firefox, the progress bar is displayed immediately after the user clicks ok to the confirmation request. In Internet Explorer, it does not appear until the application process of return with the return message.
  
  Any help would be greatly appreciated.

  Hello

  OK, it wasn't - it is just because there was a bug in my process it seemed that it worked. Sorry end that.

  So I re-tested, and the same problem that you experience will occur if you use Chrome. I think the best way is to use the technique suggested in the original thread that you connected. I so like this:

  function AjaxTest(){
       if(confirm("Are you sure you want to bill this Invoice?")){
            html_ShowElement('AjaxLoading');
            var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=IE_TEST',$v('pFlowStepId'));
            gReturn = get.GetAsync(g_AsyncReturn);
       }
  }
  
  function g_AsyncReturn(){
       if(p.readyState == 4){
            alert(p.responseText);
       }else{
            return false;
       }
  }
  

  That seems to work for me.

  In addition, you will notice in the example page, it shows the AjaxLoading element when loan State == 1, but in my experience, it doesn't work well not with chrome, so who's right for which I left out of the call back and just show before the process begins.

• Call for a process of page by clicking a link

  I have a report of the Apex with several lines and a column of link in. I would like to be able to call a page process to work on the line with the clicked link... I also need a couple of settings somehow to the process page that he calls a procedure that requires the parameters to operate correctly.
  
  So-
  When I click on a link on a line... maybe a couple of hidden objects page get ready.
  The page is then submitted and my process calls the procedure by using the values of the elements defined above as its parameters.
  Control is subject to the original page.
  
  So, basically, I'm trying to allow a user to perform repetitive actions on each line.
  
  My thought was to use a URL in the link and perhaps Javascript... or I am barking the wrong tree and is there a better way rather than a link?
  
  Thoughts?
  See you soon
  Ken

  You have the right idea. JavaScript is the way to go. Assuming that the values that are passed are part of this line of data, you can build the call to process JavaScript.

  Create two hidden objects on your page, make sure that they are not protected.
  say P1_CITY and P1_STATE

  Say your city query included and the State, define a column in the report as a link of the URL target with the following url

  JavaScript:MyFunction('#City#',_'#State#');

  Then set a javascript function in the HTML header section page

  function myFunc (City, pState) {}
  $x_value ('P1_CITY', City);
  $x_value ('P1_STATE', pState);
  doSubmit ('RUNPROC');
  }

  Then a process on the page did you want and which is conditional on the APPLICATION = "RUNPROC."

• 4.2 DOC BUG: all about the application process

  "There is an error in Oracle Application Express Application Builder User Guide version 4.2 §8.8.1 " "on the implementation of the application process":

  A process On Demand is a special type of procedure of demand that has a Point of On Demand process and executes when it is called from a process On demand page level or a browser AJAX call. On-demand processes are useful when you have logic of PL/SQL that you want to run different execution points on several pages.

  At the request of the process generally must be created on a page and not at the level of the application. On request, process created at the application level are created with an initial authorization scheme of must not be Public user. This prohibits the process invoked with users in authenticated sessions.

  As it is perfectly possible (and desirable) at the request of the application process to be invoked, [that] by authenticated users, this should probably read:

  A process On Demand is a special type of procedure of demand that has a Point of On Demand process and executes when it is called from a process On demand page level or a browser AJAX call.

  In addition, the second paragraph is a new addition to the documentation for APEX 4.2. What is the reasoning for not creating processes on request at the application level? I've used them for a few years as a way to provide reusable, application- wide (for example, the file downloads and the AJAX content) only items authenticated Apex sessions.

  Hello

  Thanks again. I added a note to the 5.0 docs.

  It is certainly very good create processes at the level of applications On Demand. However, if a process is tied to a single page, only, it is immediately obvious that the process belongs to the interface of this page. It's good from a maintenance point of view, because if you only use application-level processes, it may be more difficult to determine if the process is still in use and where it is called from.

• adding additional drives in the application process

  Hi, how it is possible to add additional disks in the application process? Now, go in the settings of the virtual machine in vCenter client to add disks after the virtual machine has been created in LCM. We take for the applicant specify how many additional disks and what size (just not RDM VMDK)

  Thank you

  It can get quite complicated because this is certainly not the standard features of LCM and would not be supported by VMware if this customization is not performed by the team of the Orchestration Services of our Professional Services organization... However, that being said, a general approach would be as follows:

  • Duplicate the workflow application for Virtual Machine to the category of workflow custom under user and give a custom name like ask VM

  • Add new entries to the custom workflow that are something like: additionalDiskCount (number) and additionalDiskSize (number) (which implies that all the additional disks would be the same size)

  • Update the workflow to store these values by using a standard LCM Action such as:

  System.getModule("com.vmware.lcm").addDataToTokenKeyAsString (provisioningToken, additionalDiskCount, "additionalDiskCount");

  System.getModule("com.vmware.lcm").addDataToTokenKeyAsString (provisioningToken, additionalDiskSize, "additionalDiskSize");

  The two lines above will store the specified user to other values that the token of data in the database of LCM and you will be able to get it back later because it is related to this particular request token.

  • Hide the initial request button of the tab requests and create a new button that points to your custom workflow

  • Create a new workflow that takes an object of lcm:ProvisioningToken as an entry called "token".

  • Inside of this workflow (let's call it 'Add disks to ask'), you will need to retrieve the additionalDiskCount and additionalDiskSize values that have been stored with the token:

  additionalDiskCount = System.getModule("com.vmware.lcm").getDataFromTokenKeyAsString (token, "additionalDiskCount");

  additionalDiskSize = System.getModule("com.vmware.lcm").getDataFromTokenKeyAsString (token, "additionalDiskSize");

  • You then get the object of VMware3:VirtualMachine of your token:

  VM = System.getModule("com.vmware.lcm.vim3").getVmFromToken (token);

  • Then, using those extracted values and the virtual computer object, use a loop to pass these parameters and some other default values you want in the workflow 'Add drive' (it's in the category library/VIM 3/Virtual Machine management/Device Management workflow.)

  • Once you have confirmed that this new workflow 'Add disks to ask' is working properly by passing only an object token with these entries of additional data stored with them, you can add this workflow for the reminder 'onCreate '.

  The above process is a general approach that could be taken. The specifics of real workflows that you create are up to you and the support of this customization

  Good luck!

• Application process, do not run after the validation error

  Hi all.
  
  APEX 4.1
  XE 11 GR 2
  WIN7
  Firexfox
  
  I have a page where I add additional javascript code to a page by using htp.p in a process of application "before the footer. It works fine as long as there is no validation error. When the validation fails (for example a UK-check with the location of the error value "Inline notification"), the page is re-fondue, but the application process is not running and so my extra code is missing from the page.
  
  Is this intended behavior or am I doing something wrond?
  
  Andreas
  
  Addition:
  
  I tried the sam using a 'local' page process, but these do not seem to fire.
  
  Published by: Andreas Weiden on 22.12.2011 21:31

  Andreas Weiden says:

  Is this intended behavior or am I doing something wrond?

  This is the expected behavior. Generally, the process and calculations source item, the actions are not executed when the page is re-made after validation errors. They also provide great potential for confusion of side effects (for example reset to a default value for an item that had an invalid value sent).

  However, the engine provides a special treatment for the process with the built-in Inline Validation errors displayed condition so that they will be run when a page is rendered with validation errors. See + {: identifier of the thread = 493070} + for an interesting discussion on this topic.

  An alternative (and in my opinion a more classic and rather more clear) would be to generate the JS in a dynamic region of PL/SQL code on the Page zero. Always reuse the code on all or several pages, but is more clearly part of the rendering of the page as an application process and does not rely on a very obscure condition, being the only way you can make it work.
