Application Express :: Passing Item Values To Javascript
Nov 23, 2012
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 ?

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 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 am using the following code in Java Script function
function notNull(object){ if(object.value=="") alert('This field must contain a value.'); }
I am then calling the function from one of the page item under HTML Form Element Attributes by using the following
onblur="notNull(this);"
But it doesn't seem to work. I am using APEX 4.2.3

I am new to APEX and I am developing an application to manage Oracle database user accounts. I have a page (8) that has text items for the username and the database name. I have a submit button (this works fine) that will issue the ALTER USER... statement to reset the user's password and unlock the account. I have another button that should:
get the value of the username - P8_USERNAMEassign it to an application item - FIND_USER_IN_DBredirect to page in application - to page 11
The issue is that FIND_USER_IN_DB does not get populated and page 11
which is a simple report with the following query:
SELECT *FROM valid_dbWHERE username = :FIND_USER_IN_DB;
How do I accomplish this?

I have created a workflow which is going through 12 pages. At each page the user needs to choose his variables.
This could be the y-axes, x-axes, amount, surname ... etc. The variables are given to the next page via branch to next page process. Everything works well until I need to create an interactive report out of the chosen variables.
Lets say I have a variable called :P7_XAXIS with static LOV :
Amount,Amount;Date,Date;quantity,quantity
Page 8 is my IR. If I try :
Select :P7_XAXIS from mytable This will not work.
But if I try
Select Date from mytable This will work. Why? In my workflow there are several variables that can be used in a where condition. This also works. But I need to access the values before the condition and I also need to get a chart out of it.

I would like to have a table in HTML region and to display in the table some Page Items from the page.
I got the code like this:
{
<table>
<tr><td>&P1_ECEMEA_ASSISTANCE</td></tr>
<tr><td>&P1_ECEMEA_WIP</td></tr>
</table>
}
It shows the Page Item names as text, not the values. However this code without the table tags:
{
ECEMEA Request for CQT Assistance: &P1_ECEMEA_ASSISTANCE.
ECEMEA CQT Work in Progress: &P1_ECEMEA_WIP.
}
works and the Page Item values are displayed.
Is it possible to display the Page Item values in the HTML table at all or I have to use a different method of showing the values in a table? The above is only a snippet of the code. I need to display about 30 Page Items, formatted in a table with headings.
what kind of region is the best to be used or if I should only use some escape symbols in the table code.

A computation after submit pl/sql function process to trim off the first part of the string (CQ..) within the list manager values. Support for example the list manager contains values such as
CQ..SAMPLE1..TEST1CQ..SAMPLE2..TEST2CQ..SAMPLE1..TEST2
The computation process should trim off the first part(CQ..) and should return the list manager value as SAMPLE1..TEST1SAMPLE2..TEST2SAMPLE1..TEST2 Oracle APEX 4.0.2 is the version and Oracle 10g r2 is the database.

I'm trying to update a number field on an apex page by summing up the values of multiple page items. I've tried to follow this tutorial
[URL]........
especially the "Create a Set Value Dynamic Action Using PL/SQL" part.
In the tutorial example they return an page item value P3_SAL multiplied by a multiplier they've determined by another page item's case. What I want to do is much simpler in that I just want to add up multiple page item values and then display them in a number field at the bottom of the page.
so the code I tried to use based on the tutorial is in the tab: Home >Application Builder>Application 103>Page 3>Edit Dynamic Action>Create / Edit Action
Set Type: PL/SQL Function Body
PL/SQL Function Body:
BEGIN
return :P3_ITEM1+P3_ITEM2+P3_ITEM3;
END;
Page Items to Submit: P3_ITEM1,P3_ITEM2,P3_ITEM3
But it gives me an error that I need to declare the identifiers, yet it works if I only use one item and I can perform any arithmetic.
i.e.
BEGIN
return :P3_ITEM1+1000;
END;

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?

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

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 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.
