Execute javascript on page loading?

i want a javascript function to execute on page loading. it should set the local user name ( from system.properties) in an inputtext.
how can i do this?

You can't. It would be a huge security hole otherwise.
In a certain web browser developed by some team in Redmond you can use ActiveX, but that thing would by default popup a security dialogue asking the user for permission to get it.
Forget about it. Rather consider an application which runs at the client machine, e.g. a signed Applet or Web Start Application.

Execute javascript on page load

All,
I have a javascript working well on click button via javascript:html_Submit_Progress(this) but now i want to use the same code to execute onload page can somebody help me with the necessary change on this code please to make it work whenever the page loads,
function html_Submit_Progress(pThis){
     $x_Show('AjaxLoading');
     window.setTimeout('$s("AjaxLoading",$x("AjaxLoading").innerHTML)', 100);
     doSubmit('APPLY_CHANGES');
     function submit_HideAll(pThis){
     $x_Hide('wwvFlowForm');
     doSubmit('APPLY_CHANGES');
     function submit_ButtonRegion(pThis){
     $x_Hide('button_region');
     doSubmit('APPLY_CHANGES');
..appreciated in advance.

So I assume your code in PageLoad looks something like this?
$x_Show('AjaxLoading');
window.setTimeout('$s("AjaxLoading",$x("AjaxLoading").innerHTML)', 100);
doSubmit('APPLY_CHANGES');Don't put the doSubmit call in page load. That will cause a submit, then the page loads again, submits again as a result of being called on page load, etc. and that's why you're looping over and over...every time the page loads you're submitting again.
I would instead do this.
1. Make a function somewhere on your page wherever appropriate:
function html_Progress(pSubmit){
$x_Show('AjaxLoading');
window.setTimeout('$s("AjaxLoading",$x("AjaxLoading").innerHTML)', 100);
if(pSubmit)
apex.submit(pSubmit); //doSubmit is "old"...apex.submit is the new Apex 4 way of submitting
} 2. In page load DA do this:
html_Progress();
3. Anywhere else you need it called and submitted too:
html_Progress('APPLY_CHANGES');
In other words, if the caller doesn't pass anything for pSubmit, don't submit. (This would be in a page load context.)
If the caller does pass something for pSubmit, then submit. (This is likely to be pressing the Apply Changes button or whatever else.)

Oracle ADF refresh as deferred does not execute query on page load

In the oracle ADF page I have two panel boxes. (Oracle ADF 11.1.1.4)
a) Personal information panel box with PanelFormLayout (PersonalInfoViewObj) - ReadOnly View Object
b) Address information panel box with Table (AddressInfoViewObj) - Read Only View Object
For the iterators in a) and b) I have kept refresh condition as deferred and cacheResult=false. Also in b) for af:table, I have kept contentDelivery="immediate"
When page loads it fires SQL query for a) and populate the data in Personal information panel box. However for b) it does not execute the SQL query and the data is not getting populated ( in AddressInformation panel with the tables. Please note data is there in the DATABASE......)
Becasue with the refresh as deferred it was not executing the sql query for Panel b) (panel with Table and table iterator). I have tried refresh as always and refresh ifNeeded/renderModel/prepareModel however in that case it is executing the SQL query two times (twice).
Please let me know the best way to fix this issue.

Hi,
I think you need a method in an application module to init your data.
In your AM : create a method like :
public void init(){
getViewObject().executeQuery();
}In your adfc-config.xml create a methodCall from this method and a "control flow case" from the methodCall to your page.
and keep refresh as "deferred " in your pageDef.

Hmm...Disable Javascript = fast page loads, but...

...it kills the "Full Text Editor" from loading. And since the link for composing a message in HTML is wrapped in the Javascripted F.T.E., I can't access it, either.
I just had the fleeting idea to try disabling Java, and then Javascript (and then both) in my browser (Firefox 3.0.x on Mac OS X 10.4.11) to see what would happen.
SUMMON-A-MITCH!!! The pages load almost as fast as they used to in the WebX forums.
Too bad it kills my ability to also participate.

Phos±,
Is it possible to read the web pages and participate only by posting through email? Just thinking out loud…

Javascript makes page load forever in IE

I'm using this function (

to make a png file use alpha transparency proerly in IE. It
works great,
except the page loads forever. The stupid MS logo at the top
right keeps on
animating and the info bar always says downloading 1 item
(the file in
question is the one PNG file I have on teh page) Anyone know
why this
happens or how to fix?
My page is
http://dev.dosomething.org/
... the png file in question is the
black logo. (I know its in teh wrong place right now, but
thats a different
problem)
Ideas?

I would duck the whole issue by using a transparent GIF

Table executes query on page load

I have a popup in my page and a table in my popup...
I use this popup for searching among records. When I render my popup, table comes with the sql suery results (invokes in popup load)...
But I don't want the table come with the query results on load...I want table to list sql query results when I execute the search query.
I want ; On load table as es empty,then When I execute, list query results.
How Can I do this?
Here is My sql query:
SELECT KODU,ADI FROM TCARI WHERE UPPER(KODU) LIKE UPPER(:pk || '%') AND
UPPER(ADI) LIKE UPPER(:pab || '%') AND UPPER(ADI) LIKE UPPER('%' || :pai || '%')
Regards, islam

Hi,
option 1: Set the default value of the bind variable so that the query returns no result
option 2: before launching the dialog (e.g. in a actionListener) set the underlying VO into find mode

Create Simple Form Execute Query on Page Load

Hi Everyone.
I have a simple question.
I created a simple form using the wizard based on a table.
The result - 2 pages - One with a report and one linked page for maintaining data in the table (click on edit icon on page1 and page 2 loads executing a query).
My question is this: Where on Page2 can I find the variable that Page1 populated?
Meaning, when page2 loads, it executes a query and uses a variable that was populated on page 1.
I checked under processes, but cannot see the query. Also checked Region and even default value for the primary key.
This is important to me, because I might want to create a simple form that executes a query retrieving all data from the table without a where clause.
Sorry - New to this tool and environment.
Any suggestions would be appreciated.
Regards
Barend

Barend - Check the Automated Row Fetch process on the form page. The report link will pass the primary key value into an item on that page and the process will use the value of that item to fetch the row for the form. You don't see the actual query because it's all declarative, i.e., you "declared" that you want a form populated from a table. We know the item name containing the PK value for the query and we know which items to populate on the form page.

Make an AM function execute only during page load time

I have a function in the AM. I want to have it executed only during loading of the page. How can I achieve it.
Message was edited by:
mailsubhra

Thanks a lot for the link.
But my case is slightly different. I have a VO where I bind some variables. I run the first page and get some data. I am sending the fetched data from the first page to the second page using pageFlowScope.
In the second page, I am binding a fucntion which will set the bind variables with some values (the values are the ones which are fetched from the first page using pageFlowScope). The VO is dropped as a table in the second page.
So, to summarize, the situation is as follows:
There is a VO which is dropped as a table in page2.jspx This VO has some bind variables. There is also an AM function which is bound to the page2.jspx and this function will set the bind variables using setNamedWhereClauseParam(...). The arguments to this function are passed from the pageFlowScope.
Now there is a page1.jspx where I am able to select something and push the selected values to pageFlowScope.
As I navigate from page1.jspx to page2.jspx, I want the VO in page2 to refresh according to the values chosen in page1. Hence I want the function to execute only when the page2 is loaded. If the function is not called during the rendering of page2.jspx, then the table becomes empty because the bind parameters in that VO are automatically set to null.

Howto execute code on page load

I am writing a small web app that displays a table with the contents of a directory on my server. The page includes links to my page plus a parameter indicating the path of the directory or file to show (e.g. page1.jsp?C:\Dir1). This part is dynamic.
The output will be in a table as follows:
<table>
     <tr>
          <td>Dir</td><td><a href="page1.jsp?C:\Dir1"/>Dir1</a></td>
      </tr>
      etc........Where can I include the code to generate this page? I have included the code in the constructor and it works only for the first time. The problem is that once the browser forwards to the page, the page returns blank from second time onwards.
Thanks and Regards
Joseph.

Hi
I am not sure if I understand what you are trying to achieve. I assume you are trying to build an HTML table with some links and you want to display this HTML table on your Page1.jsp.
This can be achieved by setting the String value to an outputtext component with escape property turned off. Drag an outputText on to the Page and turn off the escape property for it. Now use your logic to build a String dynamically with the code for the HTML table. Some thing like
String strHtml = "<table> <tr> <td>Dir</td><td><a href=\'page1.jsp?C:\Dir1\'/>Dir1</a></td> </tr></table>"Now set this value to an outputtext component using outputtext1.setValue(strHtml);
Now you will see the outputtext displays the HTML table.
If you are trying to do something else plese let us know in detail. A sample project would help us to understand the issue in detail. Please send your sample to guda AT sun DOT com

Javascript in 'Execute when page loads', not working when paging results grid

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?

Thanks, works perfectly! I used the After Refresh and just selected the region I wanted to trigger the Javascript, and it works great. As you say the scope needs to be Dynamic.
For anyone else reading this, something which caught me out was that my reports region was using the No Template setting, and the Dynamic Action didn't work, as it requires you to use a template which contains #REGION_STATIC_ID# - which is used by the dynamic action to identify the region. Once I switched to using a template, it worked fine.

Execute javascript after update and submit in Skillbuilders Modal Page

Hi,
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.
Does anyone have an idea how to accomplish this?
Thank you!

Thank you for your answers.
Yes, I'm trying to execute javascript code on the child page, the modal one.
Basically, there's a button on my parent page which opens the modal page. The modal page has buttons Cancel, Delete and Save. Clicking Save button submits the changes and if there are errors, errors are shown and we stay on the modal page.
My modal pages are all of fixed dimensions and if there are errors, I have to adjust the other regions (adjust their height, add a scrollbar, etc) in order to show everything in the modal page.
I have written a function that does exactly that, but I have to execute the function after the page is loaded and the regions are shown. But, if I execute it using onload attribute, or setting a dynamic action which fires on page load, the function gets executed during the submit, before the regions are shown.
I hope I have managed to clear up the problem.
As always, thank you.

Execute Javascript after *.jspx page rendered

I have a page with controls and a subform with a servlet, rendering a jasper report:
               <af:panelFormLayout id="pfl1" partialTriggers="cbReportHTML">
                <af:subform id="sfRep">
                  <jsp:include page="/jasperservlet" flush="true"/>
                </af:subform>
              </af:panelFormLayout>
I want the page to be rendered before the subform (so that user can see controls on page before the report).
"/jasperservlet" generates the report in about half a minute.
I want to have a JavaScript that runs after the page is rendered (and the user sees the controls) and then it starts to generate report.
I tried to put a frame with such javascript, but the javascript is executed before user can see controls.
How can it be done?

Thank you for your answers.

Pagination - JavaScipt in "Execute when Page Loads" stop working

I'm using APEX 4.0.
I have a standard report region on a page. In the page's JavaScript - Execute When Page Loads area, I put some javascript code there to initialize hover event handlers for dropdown menus inside the report. It works fine when the report is genarated.
But it stop working when a pagination performed. For example, after clicked 'next" or any number form the pagination dropdown list.
Please advice how to fix it. Thanks.
Shiofan

Hi, Peter:
Thanks for the quick reply. That is appreciated.
My code involves only CSS and JQuery.
I have found out the reason. It is because "Enable Partial Page Refresh" was set to Yes. ( that is the default by APEX, isn't it? ). After I reset it to No, the dropdown menu does work fine after pagination.
I don't know how APEX pagination work together with report attribute "Enable Partial Page Refresh". To me, no matter what, the style sheet, the JavaScript put in page template/page header should always be included since they are common to the page. Can we say this is an APEX bug need to be fixed?
Thanks again.
Shiofan

Getting Javascript to wait until page loads

I have an AppleScript that loads a web page, enters data in a text box, and submits via click(). The issue I am experiencing is that the page load time can vary. I can address this problem generally successfully with a delay command; however, if I set the delay to long to cover all circumstances, I am wasting time, and if it's not long enough, the javascript won't execute properly with the data entry. I've fiddled around with a couple of variations of the onload & onDOMcontentloaded with no success.
if you run this code via AppleScript Editor and comment out the delay, you will see what I mean, I think:
tell application "Google Chrome" to tell active tab of window 1
open location "http://www.hanjin.com/hanjin/CUP_HOM_3301.do"
delay 3
set strbillnum to "TPE436594600"
execute javascript "var billnum = '" & strbillnum & "'"
execute javascript "document.getElementById('searchName').value = billnum"
execute javascript "document.getElementById('btnSearch').click()"
end tell
I would be grateful if anyone point me in the right direction on this case.

t is not a thread, it is a Runnable object, so calling
wait or notify on it won't even compile.No, you can call wait/notify on any Object.
>
I'll assume then, that you chopped your code up so
that it would be smaller to post.
in order to call wait and notify, you must synchronize
on the threadIf you're waiting on the thread, yes. You have to wait/notify on whatever you're synced on, and one doesn't usually sync on a thread. (Not that you couldn't, just that it's a little odd, IME.)
>
synchronized( t )
t.wait();
