Call function from button

hello, i have a jsp page and i want to call a java function when the user presses a button, how can i do that? Thanks

Yes, I already have the button in a form. Have a look at my source code
<form name="form1" method="post" action="">
<p>
<input type="file" name="filePath" >
<input name="OK" type="button" value="OK" onClick="<% readFromFile(request.getParameter("filePath")); %> "> //readFromFile is the function i want to call
</p>
</form>

Calling functions from buttons

Hi, I'm using Flash CC HTML5 canvas and I can't seen to get a button to call more than 1 function. This is a simple example of what isn't working for me:
Example
stop();
function After_Char_Picks() {
this.P2_Picks.gotoAndStop("hide");
this.Choose_Ins.visible = true;
this.P2_Picks.Rita_btn2.addEventListener("click", Set_P1_Rita2.bind(this));
function Set_P1_Rita2(){
this.P2.Player.gotoAndStop("Rita");
After_Char_Picks();
Not sure what I need to do to get the button here to call After_Char_Picks(); as well as Set_P1_Rita2();
Any help is greatly appreciated.
Thanks,
Dan

Thanks for the reply.... Not sure what's going on here, but the alert comes up just fine for the other function. However other objects will not receive commands. "this.P2_Picks.gotoAndStop("hide");" never gets executed.
I have read something about functions having scope and the return function is needed to share things like variables outside of the function. But I'm trying to direct movieclips in my HTML 5 canvas page from the function and I don't see how I would apply a return function to telling a movieclip what to do.
This doesn't make any sense to me as the function linked to the "addEventListener" works fine for any command I put toward a movieclip. What's going wrong in the second if it is being called?

How to Call Function from SAPSCRIPT

I want to Call a function from my SAPSCRIPT to get some data and print the same in the form , Can I get an example for this

Hi Nandan,
U cannot directly call function from SAPScript... For that u have to create one include in which u need to write the code. Using Perform... EndPerform u can call the same from SAPScript. See the below example
u need to write this code in SAPScript
PERFORM formname IN PROGRAM includename
USING &field1&
USING &field2&
CHANGING &field3&
ENDPERFORM
Here includename is your include type program.
u need to write this code in your include type program..
FORM formname TABLES in_par STRUCTURE itcsy
                        out_par STRUCTURE itcsy.
data : var1 like field1,
       var2 like field2,
       var3 like field3.
READ TABLE in_par WITH KEY 'field1'.
CHECK sy-subrc = 0.
var1 = in_par-value.
READ TABLE in_par WITH KEY 'field2'.
CHECK sy-subrc = 0.
var2 = in_par-value.
now u can call corresponding function using local VAR1 and VAR2. Here u can pass N no of USING parameters.
After processing on VAR3...
READ TABLE out_par WITH KEY 'field3'.
out_par-value = VAR3.
MODIFY out_par INDEX sy-tabix.
EndForm.
Here in_par and out_par are the structures which will be used to communicate with SAPScript. And this is the only way as per my view.
I m sure this code will work fine. Here i have used dummy variables that u need to change as per your requirement. If u have more queries write me back.
And yes if this works than dont forget to give the points.

Call function from data base with clob input parameter.

Hello,
In this project I use Jdev 11g.
I call function from database.
create or replace function get_fa_list (
p_fa_id_list in clob
return sys_refcursor
is
vCursor sys_refcursor;
begin
put_msg ('begin');
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;
put_msg ('Save');
open vCursor for
select rownum as id, s.*
from (
select f.latitude, f.longitude, count (distinct f.res_id) as res_count, count (*) as fa_count, 16711680 as color, res_concat_distinct (f.res_id) as station_list
from mv_frequency_assignment f, table (SplitClob (p_fa_id_list, ',')) l
where f.ext_system = 'BI' and
f.ext_sys_id = l.column_value
group by f.latitude, f.longitude
) s;
put_msg ('Open and End');
return vCursor;
end get_fa_list;
I use TopLink in ejb.
i use follow code for call function and get result.
public List<TmpResPoints> findAllPointsBI(String p_id){
UnitOfWork uow = getSessionFactory().acquireUnitOfWork();
uow.beginEarlyTransaction();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("get_fa_list");
call.useUnnamedCursorOutputAsResultSet();
ClobDomain c = new ClobDomain(p_id);
//System.out.println(c.toString());
call.addNamedArgumentValue("p_fa_id_list", c);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(TmpResPoints.class);
query.setCall(call);
List<TmpResPoints> result = (List<TmpResPoints>)uow.executeQuery(query);
uow.commit();
uow.release();
return result;
But size parameter "p_fa_id_list" is 0. (geting from temp table in Data base). this code in function >>
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;)
How I can call this function from dataBase and get result?
thx,
Demka.

What is the SQL generated?
The argument should just be the Clob value (a String) not the domain object.
Also try addNamedArgument, and then pass the named argument to the query.

Call function from layer0 through layer1

If I have a flash0.swf and it is on layer0 in VB, and then flash1.swf and it is on layer1 in VB. Then how would I call a function from flash0.swf through flash1.swf?

Okay, Here is my code for VB:
_flashx.LoadMovie(0, Applciation.startupPath & "\main.swf")
_flashx.LoadMovie(1, Applciation.startupPath & "\addon.swf")
then in addon.swf I have:
I created a button symbol and its instance name is mybutton, its an actionscript 2, since main.swf is actionscript2.
The code for the button is:
mybutton.onRelease = function() {
_level0.conn.loadMenu(1);
When I click the button, when both swf's are loaded into VB on layer 0 and layer 1, nothing happens when I click the button.

Calling function from html tag in dynamic textfield

Hi!
Tried several approaches for making this happen, but can't seem to do it. I could really use an example of how to do this in my particular case, since I'm not exactly a code - guru.....
I have a sprite menu which populates a dynamic textfield with textlabels as users click individual items in the menu in addition to ordinary actions(gotoAndStop).
As these labels appear in the textfield, I want to be able to link them to the frames assosciated with the menu - item frames. As you can understand from this, I am working with the timeline.
By enabling html rendering of text in the textfield, I have been able to link these output labels via a a href - tag, but I am not able to call a function from this html. The function I am trying to call uses a switch statement to take the appropriate actions according to which label is being clicked, but the only effect I get is the html opening a browser window...... Unfortunately I do not know how to explain this any better, but here is my code for the following:
Main Timeline, frame 1, actions layer:
[AS]import flash.display.*;
import flash.events.*;
import flash.display.Stage;
var buttonTrace:TextField;
var sectionNames:Array = new Array("Frontpage","Introduction",
"Designparadigm", "Tooling", "Maya & c++ API", "Geometric Vectors","Lindenmayer systems","Artificial Life",
"Projects","Litterature","Disclaimer","Site credits","Newsletter & Rss",
"Blogging","Plugins","LINKS");
var sectionCount: int = sectionNames.length;
var menu:Sprite = new Sprite();
menu.x = 452;
menu.y = 172;
this.addChild(menu);
buildMenu();
function buildMenu():void {
for(var i:int=0; i < sectionCount ; i++){
var item:MovieClip = new MenuItem();
item.labelName = sectionNames[i];
item.targetClip = this;
if(i<4){
item.y = i*125
menu.addChild(item)}
else if (i>3 && i<8){
item.y = (i-4)*125
item.x = 125
menu.addChild(item)}
else if (i>7 && i<12){
item.y = (i-8)*125
item.x = 250;
menu.addChild(item)}
else if (i>11 && i<16){
item.y = (i-12)*125
item.x = 375
menu.addChild(item)}
}[\A]
Then, for the movieclip called MenuItem, I have button placed on the first frame of the timeline, and this code in the actions layer:
[AS]import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.display.Stage;
import flash.text.TextField;

Calling function from PL/SQL block

Hi,
A very simple question.
A have a function called "test1" in my database. It is there i double chekked.
I would like to call this function from a block:
DECLARE
BEGIN
TEST1(1202);
END;
This gives me an error.
Why is this?

Why is this?Hello
A very very basic thing to do when you get an error is to include details of it. That helps narrow it down from one of the 1000s of potential Oracle errors it could be.
Anyway, a function returns a value, and in PL/SQL you need to capture that otherwise you'll get "an error". Modify your code like so
DECLARE
l_Test1Val VARCHAR2(4000); --CHANGE THIS TO BE THE SAME AS THE RETURN TYPE FOR YOUR FUNCTION
BEGIN
l_Test1Val := TEST1(1202);
END;HTH

Calling Functions From Import Integration Script

I've got an import integration script that runs fine, however I also have several DataPump scripts that are used in FDM to change specific columns as they come in. I can take the code from the scripts and add to the Import Integration script, but I would rather just call those other functions from the VBScript. I don't see any docs on this, and I'm just wondering if anyone has done this or can describe how I can do it.
Is it possible? Since the standard import scripts reference the strField and the strRecord, can these functions be called from the import integration script?

strField and strRecord are arguments passed by the application to the import function. The represent the field as defined by the import format and the record that is being processed during the import.
Given that, I'm not sure how to answer your question.

Calling function from sql folder vs report

Hi,
A report based on a custom sql folder is taking a long time to run. One of the things that I noticed is that when I run the sql in plsql it takes a long time, but if I remove the row where I call a function, it runs pretty quickly.
In general, is there a difference between running a function from the sql custom folder and calling it from the report itself?
Thanks.
Leah

Hi Tamir,
I might check out the execution plans, but truthfully, understanding the plans and the meaning of the differences is not my strong point.
I thought that maybe there was some general rule that, for instance, it is better to keep functions out of the sql folder and use them in a condition in the report itself, or the opposite, or that maybe it makes no difference at all.
I appreciate the response.
Thanks.

What is the syntax for calling function from class file by jsp

does anyone here knows what is the syntax of how to call a function from java class file by javascript code or any way to call it?
and where should i put the calling function code? because the function is called depend on the user click.
for example
<%=pc.functionName(a,b)%>
for the variable a and b, how can i get the value from html textbox and put it in a and b...
urgent needed...
thx

Jsp's are executed before the Html forms are created and loaded. Dont try to use a java code function calling on a javascript click. You'll have to explicitly redirect it into a servlet where in you can call the function you want.
Well! another way could be using AJAX. That seems to be powerfull enough and it might also serve your purpose.
Hope this helps

Put SQL query in a function/ call function from region

How can I write a SQL query (like SELECT EMPNO, ENAME, JOB FROM EMP) as PL/SQL function, and then call this function from the PL/SQL Function Returning SQL Statement region?
Thanks, Tom

thanks jverd for your quick reply.
I know passing in a reference to an object will do the job if I want to change the value several parameters in one function call.
But I want to ask, is there any other ways?
the following code works.....
public class TestParameter {
     public static void main(String[] args) {
          Test2 t2 = new Test2();
          invokeChange(t2);
          System.out.println("x = " + t2.x + "\t y = " + t2.y);
     static void invokeChange(Test2 t2) {
          t2.x = 10;
          t2.y = 15;
class Test2 {
     int x;
     int y;
}

Getting session hang When calling Function from SQL query

Hi All,
I am using Oracle 8.1.7.4.0. I have a fucntion in a Package and I am calling it from the SQL query. When I am firing the query my oracle session is going to hang position and I am not able to any thing. I have to kill the session.
But this same thing is working fine in Oracle 9.i.
There are no out parameter and no DML, DDL and DCL statement in this fucntion.
Could you please get back me what is the problem on it.
Regards
SUN

Check why your session hangs.
Just a few ideas:
* Blocking locks?
* Endless loop?
* Performance (maybe it is just slow in orac8i and you have to wait a bit longer). Check the execution plans of the SQL statements in your function.
* Don't use a function, but direct SQL, it is faster in both versions.
