Application Express :: Set Variable Via Javascript
May 16, 2013
I got a long string (length exceeds 32512) from Javascript, and want to pass the sting to a variable to a item called P_SQL
I use *$x("P_SQL").value* in javascript to set the value, but my process couldn't get the value before I submit, however, when I do submit it reports an error like this : Bad Request
Your browser sent a request that this server could not understand.mod_plsql: /pls/alq/wwv_flow.accept HTTP-400 Value param too long. Length is 216343. Upper limit is 32512
how to handle this conflict ?

I have a .js process in the before header of a page which has this pl/sql process using htp script javascript function {code}
function check(flag_val){ if(flag_val=="N")
document.getElementById("btn").disabled = true;
else
document.getElementById("btn").disabled = false; }
{code}
and then there is the actual pl/sql process which has a cursor
{code}
declareflg varchar2(1);
..begin selectflag into v_flagfrom table where rownum = 1;
-- actual conditions are different but this returns one value.
Then below using htp package I had html table with something like
<td align="right">
<button class="btn btn-success" type="button" id="btn" onclick="check(flg);"
title="Accept Lead" style=" width:50px;">Flag value</button> </td>
{code}
For some reason the script function is not called if I use onload. If I change the onload to onclick it works. Also, if I pass check(flg) it does not work. If I use check(''N'') then is works fine. question is how do I pass a pl/sql variable flg in this case to a javascript function as a parameter? I basically, want the value of flg checked on page load and then if it is N then disable the button. Or else keep it enabled.

I use APEX 4.2.2 and in my page I call a Modal Region to insert a new customer using AIAX and OnDemand PL/SQL process, then I need to set the inserted value into the Popup LOV from javascript. I used the code
:$('dialog').dialog('close');$('P20_CUSTOMER').trigger('apexrefresh');$('P20_CUSTOMER').one('apexafterrefresh', function() { apex.item('P20_CUSTOMER').setValue(ajaxResult, $v('P20_DESCRIPTION'));}
where P20_CUSTOMER is the Popup LOV, ajaxResult is the PK returning from the OnDemand PL/SQL process and P20_DESCRIPTION is an APEX Item of the Modal Region. The new customer is inserted successfully into the table and the PK value returned to javascript code, but the new value is not displayed into the LOV.

I have two Select Lists P58_TYPE_DOC (it shows for users that have not adm profile) and P58_TYPE_DOC_ADM (it shows just for administrator).
On my Page proprieties I have on HTML Header this code :
onload="show_fk_facture('P58_TYPE_DOC');show_fk_facture('P58_TYPE_DOC_ADM');"
I have to execute the java script when the page loads, but I cant execute the function for both items in the same time.
Because one of the items will be hidden, and the java script won't be able to find it.
I tried to use "if isNAN('P58_TYPE_DOC') else ....." but it doesnt work.

In a normal tabular form, with the add, delete, submit option, Under the add button we have the javascript.addrow() call which creates a new row. However, in my case the rows in the tabular form have some columns as display type. So when the user clicks on the add button, he cannot enter all the fields. Is there a way
1. Either to enable all columns of a new row only so that users can add all values and save
2. Or atleast open a new page where the new row is open with all editable fields?

I am struggling to set the maxDate of a datetimepicker.
In the document load of the page I have this:
$('#P64_STARTDT').datepicker("option", "maxDate", $v('P64_XFORMATSTARTDT'));
P64_XFORMATSTARTDT is in the format YYYYMMDDHH24MI
It never sets it.

How to check off checkbox with JavaScript. I tried
1) $("#checkboxID").prop('checked' , false) (jQuery)
2) $("#checkboxID").attr('checked' , false) (jQuery)2) document.getElementById("checkboxID").checked = false;Checkbox's list of values: STATIC:;1
Checkbox always states checked. When I append 'checked="checked" ' attribute (or simply checked) to this unchecked checkbox in Firebug nothing happens. Why ? I execute JavaScript code in Dynamic Action on button click. All other controls (textareas and textfields) are cleaned successfully except this checkbox. "Effected elements" property includes all needed items.

Apex version 4.1.1.00.23IE8 (8.0.7601.17514)Firefox 25.0
I have a tabbed form that I need to conditionally disable rows (making them read only). I'm using Javascript to set the attributes of the fields that need to be set.A request was made to make the font color of the read only fields black so that they're easier to read.I'm not able to get the font changed to black on the fields that are Select Lists in Internet Explorer. They are staying gray, however, they are set to black in Firefox. The JavaScript code for one of the Select List is:
var curr_id = html_GetElement('f42').id; //Group
$x(curr_id).disabled = true;
$x(curr_id).style.background = "silver";
//$x(curr_id).style.color = "black";
$x(curr_id).style.color = "#000000"; //black

APEX 4.2 - Base code from Denes examples
CODE ON HTML HEADER
<script language="JavaScript" type="text/javascript">
function f_setglp(pThis,p_app_item,p_other_record_level_item)
{
var curr_id = $x(pThis).id; // OK !
var curr_glp = $x(p_app_item).id; // returns undefined
var curr_orli = $x(p_other_record_level_item).id; // returns undefined
[Code]...
The Javasxcript function fires OK on click in the "Product" attribute but: PMO_GLP_PK is an Application Item that Javascript can´t reference as I called YES_NO is another tabular form attribute and the reference returns also "undefined"
what is the best way to implement this ?

Note, I'm using APEX 4.1.1
The scenario is that I have tabular form that was manually created from a collection; the collection name is "COMPANY"
Within this tabular form, I have number of selection lists (apex_item.select_list) and for each, I fire off a JavaScript based on the "onchange" event (e.g.,'onchange="updateCollection(' || seq_id || ', 10, this.value)"'); updateCollection is a custom function I created. Right now, all it does is alert me with the specifics of the of the selection list. As a further example, if I select "Google" from the selection list, sequence id would be "1", attribute number would be "10" and attribute value would be "Google"
Within this JavaScript, I would like to update the value of this associated element in the "COMPANY" collection. Ideally, I would like to directly call this:
APEX_COLLECTION.UPDATE_MEMBER_ATTRIBUTE(p_collection_name => "COMPANY", p_seq => 1, p_attr_number => 10, p_attr_value => 'Google') but I could not figure out how to do this.

I have a tabular form with a few columns. THey are ID, date1, date2 and task_name. The task_name is a drop down list of tasks. Upon selecting a specific task, I want the date1 and/or date2 columns to become read only (voided out) so users cannot enter in data. I am working with a tabular form, so I figured I need a javascript function to handle the logic and to call the function in the html elements of the column in the apex environment. This will need to happen dynamically (on click) before the page is submitted. I am more lost/confused on syntax. I know I will need to know the actual column name (coo1, coo2, something like that) of my columns that I will be refering to when I use javascript.

I had a complex drill-down dashboard where I was setting page items through $s(Page Item, value) from the Chart Links. But when I did the same thing in APEX 4.2 EA on [URL]...it is simply opening a blank page. whether in 4.2 that Java API has been removed?

I am using APEX 4.1 to build the application. I have 2 select list region in the page where one region consist of certain values.On calling a javascript function it is able to move the value from one select region to another. After this I click on the modify button where in the value move out of the first select list region to the second will be updated in the table.
Although I could see the values are not being updates. On putting alerts after the value being fetched in the javascript function and clicking the Modify button I can see that no data is being reflected in the alert. Hence the data is not being passed from the second select list APEX item to the javascript function.

Had some issues with a page on which i changed the value of an item using javascript and added a dynamic action (dummy pl-sql) that submitted the item. The problem was that if i also used $x_disableItem to disable the item in the function that set the value , the value submitted was always null. However if i used the "Disabled" attribute from the item Settings and remove the calling $x_disableItem in the function, the value submitted is correct.
To reproduce , create these objects on a page (default everything not specified):
<li>P1_VALUE - textfield
<li>P1_SET_VALUE - button calls "javascript:setValue();"
<li>P1_SUBMIT - submits the page
<li>Dynamic action:
- Event - Before Page Submit
- Execute PL-SQL (begin null; end;) - Page item to submit P1_VALUE
[code]....
So i have two questions:
1) Why is the implementation different (would have expected to behave in the same way)?
2) When using the javascript API function $x_disableItem , why is the value submitted null?
P.S: For the workaround i removed the $x_disableItem call with calling a custom function that toggles the read-only attribute of a given item.

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
I am about to embark on my first APEX development and have got far as the login screen. I disabled JavaScript just to see what would happen if someone had it disable, it turned out by disabling javascript the whole login region dissapeared. I am wondering how to develop the application so it works when javascript is disabled. I am using the cloudy theme. Not sure how to develop the application as its got to work with JavaScript disabled.

I'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page. I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.

On a tabular form I have 50 columns each an input box , (basically 50 weeks of the year)
in these boxes I want to make them numbers only and max length 2
currently I have in the ELEMENT ATTRIBUTES for each column
OnFocus="javascript:this.maxLength=2"; onKeyPress="return numbersonly(this,event)";
( I have a function called numbers only in page 0 )
what I would like to do , to make it more maintainable is to remove all the calls in the element attributes of each column
and put it in 2 dynamic actions how would I go about this ?
I have tried using jquery selector of input:text to call javascript code on both events , Get focus and Key Press for every text box but its not working .

I have some Javascript in an Apex page, running in 'Execute when page loads'. It does some stuff to a results grid. It works fine on page load, but then doesn't run when I page through, or sort the grid. I presume this is because the grid is being sorted / paged using Ajax, which means the page isn't being fully loaded. Is there anywhere else I can put the code so it gets applied to the grid on sorts and paging?

We have integrated Oracle Access Manager 11gR1 with Oracle Apex 4.1. The OAM-Apex integration is working fine. Now we want an additional header variable to be passed from OAM to the Apex application. This new header variable will be user's sAMAccountName in Active Directory. OAM is integrated with AD and the AD users are successfully able to access the Apex applications.
The three header variables which are configure in OAM right now are:
Header variable name Value
1. OAM_REMOTE_USER $user.userid
2. OAM_REMOTE_USER_EMAIL $user.attr.mail
3. OAM_REMOTE_USER_GROUPS $user.groups
We need an additional header variable as mentioned below:
Header variable name: OAM_SAMACCOUNTNAME
Value: $user.attr.samaccountname
The new header variable was added in the OHS server's dads.conf file like shown below:
=========== dads.conf =============
...
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_GROUPS
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_EMAIL
PlsqlCGIEnvironmentList HTTP_OAM_SAMACCOUNTNAME
But we are not able to read the value of this attribute in the Apex application.On the Apex application, we have a text box which shows the value of this header variable. This textbox is attached with the following stored procedure call to fetch the header variable:
===================
begin
:P1_HEADER_VALUE := owa_util.get_cgi_env( 'HTTP_OAM_SAMACCOUNTNAME' );
end;
The textbox shows the correct value if HTTP_OAM_REMOTE_USER is passed to the get_cgi_env method but does not shows anything when HTTP_OAM_SAMACCOUNTNAME is passed to the same method. if I am missing some configuration to pass the HTTP_OAM_SAMACCOUNTNAME haeder variable from OAM to Apex.

I'm trying to connect a javascript UI control within my page to an APEX Application Process. The control calls the application process via AJAX and appends a variable number of GET / POST parameters to its URL.What is the best way to obtain these parameters from within the PLSQL procedure of the process? Or is there a better way to connect my javascript AJAX control to the Database behind my APEX app?

My question is, if I define an object type (create type ... as object ...) is it possible to hold a variable of this type as the session level? For example, if I am creating an order using multiple web pages, it would be much easier (and intuitive) to create and manipulate an order object than to hold the data in generic collections.
If that is not possible, is there some way to make a generic Apex collection appear more application specific? By this I mean some way to map the columns C001, C002, ... to more intuitive names such as CUST_NO and ORDER_DATE. I had considered possibly creating a view of the APEX_COLLECTIONS view which would rename the columns but then I would also have to create a bunch of instead of triggers if I wanted to update it as well.

I am using Oracle 9i. The code is also PL/SQL cartridge web application code.
My problem is that while trying to assign a value within an exception, it is not being accessed correctly in a Javascript function
It is as if it is not being set. The value stays "N".
CREATE OR REPLACE PACKAGE BODY CIRC_PORT.pk_start_runs IS
v_alert_msg varchar2(1) := 'N';
BEGIN
runjob(param_1,
param_2,
[code]...
The retrieved value, v_alert_msg, should be referenced in a JavaScript function each time a Submit button is hit:
function doSubmit( theForm )
{
var vacpack_error = "'||*v_alert_msg*||'";
if (vacpack_error == "N") / -- ALWAYS DOES THIS -- /
{
<do something>
}
else
{
<do something>
