Document.form.element.value

Hi All,
I'm very new to javascript and had a quick question! Her is a sample of my code.
<script language="JavaScript" type="text/javascript">
                  function fnShowText(txt)
                    var x = document.getElementById(txt);
                    var e = document.getElementById(txt).name;
                    var sText = x.options.value;
                    var f = e.concat("b");
                    for (i=0; i<mainform.elements.length; i++)
                       if (mainform.elements<i>.name == f)
                     document.forms[0].elements<i>.value = sText;
                </script>
I know what the value of elements is, but I want this script to be dynamic. Instead of looping through all the elements to find the value 'i' like I am currently doing it. This is bad response time. Is there a way to skip the looping and make this call dynamically if I already have the name of the element?
Thanks in advance!
Eric
By the way there is a 'i' after elements but for some reason it isn't showing up on this board.

if you have a input tag in your html page you can go about it the following ways.
<input type=text name="t1" id="t1"></input>
<script>
document.getElementById("t1").value = "here";
document.getELementsByName("t1")[0].value = "there";
</script>
getElementsByName brings back an array.
getElementByID gets back one object.
You should test your taget browsers with both of these. I know that IE works fine with getID, but others do not.

How to set a form element value using javascript?

Hello,
I have been using the following two functions in AS 9.0.2 to set form values in javascript and it works correctly. However, the same code does not work in AS 10.1.2.0.2. Would appreciate if someone could let me know how to set form elements using Javascript(onchange of a field).
function set_item_value(p_field_name, p_value)
var v_index, v_full_name;
for(v_index=0; v_index<document.forms[0].length; v_index++)
v_full_name = document.forms[0].elements[v_index].name.split
if (v_full_name[2] == p_field_name)
document.forms[0].elements[v_index].value = p_value;
function get_item_value(p_field_name)
var v_index, v_full_name, v_return="";
for(v_index=0; v_index<document.forms[0].length; v_index++)
v_full_name = document.forms[0].elements[v_index].name.split
if(v_full_name[2] == p_field_name)
if(document.forms[0].elements[v_index].type != "radio")
v_return = document.forms[0].elements[v_index].value;
else
if(document.forms[0].elements[v_index].checked)
v_return = document.forms[0].elements[v_index].value;
if(v_return == " ")
v_return = "";
return v_return;
Thanks
Dev

This is not the best way to write JavaScript in Portal environment!
You can't be sure that a form is the first in the html source!
In Portal you change the order of your portlets, and also you can have several instances of the same portlet on the same page!!!
You should use qualified form and field names!
Please check the following JPDK methods:
UrlUtils.htmlFormName
HttpPortletRendererUtil.portletParameter

Directing workflow transition based on form element value

Question 1
=======
How can workflow change values in a form element?
Example: We have an expense aproval form.
If the form transits from state ManagerA to state Reject, I want the form element Rejected by: to be automaticaly set to value ManageA.
How ho achieve this?
Question 2:
========
How can a workflow read a form element and based on the element value automatically transit to other state?
Example: An expense aproval form is in state ManagerA.
If a user set the form element Rejected by manually to the value ManagerA, I want the form to be automatically transited from state ManagerA to state Rejected.
How ho achieve this?

Dangross, thanks for the reply. Yeah, that Transition on Entry Data Value will do the job.

Pass form element value after insert

I have a page with an insert behaivor, it inserts all form
elements BUT one,
I need to pass the value of this form element to the next
page.
If I apply the 'insert' behaivor, it does the insert well,
but the value of
the form element is not passed to the next page, how can this
be accomplised
Aleks

I can't because the value is entered in the form and there is
no value until
it is posted. Remember this is an 'insert page' that then
redirects to the
next page.
I used redirection as:
<%
' *** Insert Record and retrieve autonumber: set variables
If (CStr(Request("MM_insert")) <> "") Then
MM_editConnection = MM_eimmigration_STRING
TM_editTable = "dbo.Users"
TM_editRedirectUrl =
"SPLinkFamilymember.asp?FamUserId=Request('relations')"
Last line has the redirection link.
but didnt work, I get following error, next page I get this
value:
Request('relations')
Instead of the actual value selected in the form.
I am using ASP/VB and MS SQL 2000

Need some advice on form element values?

Hi All,
I have an issue with the website i am currently developing. Its a e-commerce site for a memorial masons. For each product/memorial there are several elements, drop down menus and text fields to retrieve the information needed, there is also a 'total' that as customers make their choices the amount for each element is added to this total. My problem is, on the two elements 'engraved_designs' and 'sandblasted_designs' i need to calculate that amount into total but also i need to retrieve the code of the design chosen for back office reference. I can't use both the price and code in the 'value' attribute as that will stop the calculation function from working. So how am i to get the amount to calculate at the same time as being able to retrieve the code chosen when submitting the form?
http://www.milesmemorials.com/product-GH54.html

Ok sorry i didnt realise that would do that, to have this '75#P4.2' come up in hidden field is exactly right for what i need. But i think maybe i haven't amended my php file for this properly, this is how it looks -
<?php

How to set a value of a hidden form element

I want to add a hidden element to form and set the value
from javascript before calling submit().
My javascript function
function getBdSubmit()
alert('getBdSubmit function called');
document.forms.DataForm.event.value="getBd";
document.forms.DataForm.submit();
The Javascript is called from onChange of a poplist as
DataForm:getBdSubmit();
I am getting alert message, but an error in next line as object document.forms.DataForm.event.value is null or note a object.
How can access the hidden element in form?

I got a work around. I gave a name to the form in the datapage and set the type to the type specified in the struts-conf.xml file. Then i was able to access the hidden field "event" from the javascript as
document.forms.DataForm.event.value to set different event names

Passing Session Values to the Tabular Form Element of a Report Column

Hello,
I'm running application express version 2.0 with a 10.2.0.2.0 database on a 32 bit windows box. I'm trying to figure out sneaky a way to pass the &APP_PAGE_ID., #APP_PAGE_ID# or V('APP_PAGE_ID'); as an element attribute of a Report Tabular Form Element set to display as a Select List (named LOV).
It seems that whatever option I choose, the Element Attributes field will only render the literal value of what I have entered. This is part of the solution but I would like to find a way to pass the current page id.
What I'm trying to do is utilize the ONCHANGE attribute to redirect to a report page in my application when the value from a Select List (named LOV) is selected.
I could work around this by creating my own table output with PL/SQL and HTP.P commands but would really be interested in finding out if I can use the reporting structures which are already available through Application Express.
Any ideas?
Thanks.
Justin.

Thanks for the response Earl. To clarify this is what I've done and what I hope to achieve:
I currently have a LOV for my application that identifies a number of database report types: DB Options, DB Parameters, DB Version, and so on.
I have an application express report being generated for the databases I'm monitoring and it displays as follows:
- HOST -- DBTYPE -------- DBNAME - DBREPORTS
=====================================
- SVR 1 - Oracle 9.2.0.1 - DEV -------- [LOV HERE]
- SVR 2 - Oracle 9.2.0.7 - TST --------- [LOV HERE]
I am displaying the LOV on my report the the options under the reports attribute tab in my application builder. I insert my LOV select list by editing the DBREPORTS column and set the "Display As:" option under Tabular Form Element to "Select List (named LOV)"; I have also added my LOV to the "Named LOV" option under List of Values.
So far this achieves everything I would expect and works quite well (a select list with my report types appears in my monitor report for each DB that is returned).
What I'm interested in doing now is opening a DBREPORT for a given database by simply choosing the report type from my LOV. I can set the "Element Attributes" option under Tabular Form Element to execute a javascript call for any valid event (in my case I'm using ONCHANGE).
My only issue is that I cannot find a way to pass any session values from my page to my Element Attribute. If, in the Element Attributes field I enter:
onchange="alert(this.value);" //my dialogue box will display the value of my current selection when I choose a report type.
What I'd love to be able to do is something like:
onchange="alert('&APP_PAGE_ID.');" //so my current page id is written to the element.
Unfortunately, only my literal text seems to be rendered. Rather than having my dialogue come back with my page number, say 75, I receive the literal value &APP_PAGE_ID.
Notwithstanding any quote issues, I've tried to dump a test html attribute to my source html by entering any of the following in the Element Attributes field:
test=&APP_PAGE_ID.
test=#APP_PAGE_ID#
and as a shot in the dark knowing that I'm not using PL/SQL:
test=V('APP_PAGE_ID');
In every case when I view source I see the literal value of what was entered in the Element Attributes field (ie "test=&APP_PAGE_ID." instead of "test=75").
What makes things a little more frustrating is that I can drop &APP_PAGE_ID. into the Column Heading field (ex My Heading &APP_PAGE_ID.), it renders as I would expect; "My Heading 75". If we could find a solution to this, I could see a number of slick uses for this type of functionality.
Hope this helps,
Thanks.
Justin.

Javascript - document.forms[0].elements

Hi,
I'm trying ...

for(var i=0; i < els.length ; i++) {
var compVal = els[i].alt;
Its working in IE but not in Safar. Any alternative. Please help?

Any other function to access alt attribute in Javascript. If not, How can I do in jQuery..

Use DOM to get the element value of XML document?

I can not to use the method getNodeValue to get the element value of XML document. How can I do for it?
For example, for element
<address>125 Smith Avenue</address>
how to get the value "125 Smith Avenue" by using DOM?
Thanks

Thanks for all of you.
The code indicates that I need to get the node by tag name. If I do not know the distribution of the elements and want to traverse all nodes. If the node contains value, I retrieve the value. How to implement the general case.
For example, my XML file represent a directory hierarchy and looks like
<root>
<usr>
<user>user1
<file>file1</file>
<file>file2</file>
</user>
<user>user2
<file>file1</file>
<file>file2</file>
<file>file3</file>
<file>file4</file>
</user>
</usr>
</root>

How to use Spry.Utils.extractParamsFromForm to get value of a form element

Can we use Spry.Utils.extractParamsFromForm to get value of a
form element ?
I tried this
quote:
var cid =
Spry.Utils.extractParamsFromForm('adForm','category');
Here the form name is adForm and category is an select item.
This gives me error

elements.join is not a function
Any idea on this guys.

Javascript: parent.framename.document.forms[i].elements.length

I have a PHP-Script 1 with an iframe.
In this iframe an other PHP-Script 2 is loaded, which contains several forms.
In one of this forms I make a call by button with onclick="..." to a javascript-function.
The javascript-function is contained in an external file *.js. Declaration in PHP-Script 2: <Script type="text/javascript" src="WartArtikel-Probe.js"></Script>.
Inside the javascript-function I use:
Scenario 1:
var i = 0;
var anzelem = parent.framename.document.forms[i].elements.length;
or:
var anzelem = parent.frames[0].document.forms[i].elements.length;
or:
var anzelem = window.document.forms[i].elements.length;
When I press the button, the javascript-function gives no answer.
But when I start PHP-Script 2 directly (not inside an iframe) and the javascript-function is written as:
Scenario 2:
var i = 0;
var anzelem = document.forms[i].elements.length;
this example works!
How can I get an answer in scenario 1?
Additional suggestion: Is it possible to switch the browser into a development-modus, where javascript-syntax-errors are displayed? This could be very helpful!

To view script errors, you can keep the Browser Console open in a separate window. To open that, you can use either:
* Ctrl+Shift+j
* "3-bar" menu button > Developer > Browser Console
* Tools menu > Web Developer > Browser Console
My guess is you will find some kind of security related issue.

Column value substitution in tabular form element attributes

We started to discuss this at Re: Tabular form with Ajax
I also mentioned this at Re: how to make only some rows editable in html db.
but thought that this deserves its own thread.
In Doug's sample Sudoku application in that thread, he uses #COLUMN# substitution in the Form Element Attributes and it works fine, but in my example page at http://htmldb.oracle.com/pls/otn/f?p=24317:219 I used the same technique and no matter what I do, the #COLUMN# substitution is not expanded by the Apex engine.
This is driving me nuts, any ideas why it works in one application but not in another?
Thanks

Hm, you might be right.
I copied your row template and modified it at http://htmldb.oracle.com/pls/otn/f?p=24317:219
The styling looks terrible, not sure why, the template is simply
<tr>
<td class="t10data">#EMPNO_DISPLAY#</td>
<td class="t10data">#ENAME#</td>
<td class="t10data">#JOB#</td>
<td class="t10data">#MGR#</td>
<td class="t10data">#HIREDATE#</td>
<td class="t10data">#SAL#</td>
<td class="t10data">#COMM#</td>
<td class="t10data">#DEPTNO#</td>
</tr>I had a lot of trouble getting this to work because the wizard generated tabular form appends 2 hidden fields containing the PK and the row-checksum to the last (editable?) field on each row. If the last editable field has #COL# substitution, it expands the substitution and forgets to close the INPUT tag thus causing malformed HTML (I think this is a bug in the rendering engine).
The readonly condition is sal>1000 which now works. The SAL>1000 fields are now readonly.
But now the update process is broken. If I enter a number in the first blank SAL field (empno=3641) and click Submit, I get no errors but the change is not saved. Wonder why.
Hopefully, Scott (Spadafore) will take mercy on our amateurish experiments and give us some definitive answers soon!
Thanks.

Hiding toolbars in Interactive form element

Hi all,
I am using interactive form element to embed a purely readonly pdf (but content is dynamic) since Iframes is deprecated (any other way?).
I wish to hide the toolbars, options of thumbnails etc. I added the code below to my view controller. However, it does not seem to work. All the toolbars are still showing. Did i do something wrong?
IWDPDFDocumentInteractiveFormHandler iFormHandler =
WDPDFDocumentFactory.getDocumentHandler(wdThis.wdGetAPI(),
"InteractiveForm");
IWDPDFDocumentAppearance appearance =
iFormHandler.getDocumentContext().getAppearance();
appearance.hideMenuBar(true);
appearance.hideToolBars(true);
appearance.hideWindowControl(true);
TIA

Hi,
As the error suggests that you do not have any certificate configured in your key store which is required to authenticate the client to the ADS. You would require to install a client certificate on your Web Dynpro/Portal server that will be used to authenticate the Web Service call to ADS.
But the question is whether you need "Https" for a server to server communication (from your portal server to ADS server) ? Normally, these two servers reside in the LAN. And i suppose you are not using any of the secured functionalities of interactive form (for example, digital signature, certification etc.). I assume that you need "https" call from browser to the portal server and then from portal server to the ADS should be on http. Please confirm on that. If that is the case, then you can follow the section below to change the "protocolSchemeForADSCall" to "http" always. This is what you would need to do in the Visual Administrator where your portal/web dynpro is installed:
In Visual Administrator. Go to ->
Server -> Services -> Configuration Adapter -> webdynpro -> sap.com ->
tcwddispwda -> Propertysheet default
Then goto property sap.protocolSchemeForADSCall
This property is available after you apply SAP note 849730.
Possible values are:
- request: same protocal scheme than the request to Web Dynpro has
- https: always use https
- http: always use http
SET the value as http. This will ensure that web Dynpro to ADS communication always happens on http, rather than on https.
Should you need to install SSL based communication between the two, you would need to follow the note:
