Calling PL SQL in a Javascript function

 

I've written a function :
function removeCouvent (id)
//var empSelectObj = document.getElementById(empSelect);
var ajaxRequest = new
htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=Del_couvent',0);
ajaxRequest.add('CodeCouv',id);
ajaxResult = ajaxRequest.get();
if(ajaxResult)
          alert("test1");
     else
          alert("test2");
ajaxRequest = null;
with the pl / sql app process (Del_couvent) :
BEGIN
DELETE FROM COUVENT WHERE CV_CODE= :CodeCouv;
END;
It does nothing, no deletes, any idea ?

  • Call abap method in a javaScript Function

    Hi all,
    I want call a abap method via a javaScript function in a view of a bsp application.
    Does someone know how it works?
    regards Alex

    Hi,
    You can either change the location of the page to a target URL usinng "document.location.href = 'targeturl'. So targeturl is the fully qualified url necessary to call the method.
    Or you can take a look at XMLHttpRequest object (http://www.w3.org/TR/XMLHttpRequest/) which can create requests to a given URL. You can parse and use the data returned by the target url.
    Hope it helps,
    Regards.

  • Example of calling PL/SQL func in JavaScript

    I need to validate a form element based on existing database value and give an alert. Does anyone know how to capture the value returned by a PL/SQL func in JavaScript variable? Thanks.

    hi,
    in the PL/SQL block 'before form displayed'
    insert the code:-
    htp.p('{script}var myVar = "' | | myPLSQLfunc | | '";{script}');
    (I have replaced the less-than and greater-than symbols with {} so that they will show in the browser)
    The variable myVar will now be available to JavaScript in the page and will have the value returned by myPLSQLfunc.
    Regards Michael.

  • Problem calling PL/SQL procedure from Workflow function activity.

    Hi,
    I am trying to call a PL/SQL procedure from within my workflow activity.
    While I am able to execute the procedure through SQLDeveloper, the workflow function does not seem to call it.
    It seems that custom PL/SQL procedures have to conform to certain standards to be called within workflow applications. I have written my procedure to conform to those standards (referred to the example workflows).
    Could someone please help me with it?
    Thanks and regards.

    Hi,
    When I've received enough alpha reviews of the first few chapters of my book, I'll make chapter five available, which deals with writing functions for Workflows.

  • Call to Applet Method from JavaScript Failed.

    I Am calling a method from a javascript function from within a web page.
    The page is loaded into a frame. The parent window of the frame has stored a reference to the applet which defines the methods. Note I am treating the reterence to the applet as a global variable. So that I can reference it methods as I navigate from one page to another.
    I have JavaScript objects defined, and I am passing them as parameters to the applet's methods. In java, the JavaScript objects are refererenced as JSObject. When I call a java method passing a JavaScript
    Object I get the following exception. Note Iam using j2sdk1.4.2_01 on a Windows 2000 Professional System. This problem start occurring after the recent Microsoft Worm/Virus a fix was loaded on my system which resulted in the following bug. Could someone please help me.

    thanks in advance for any enlightenment,

    Hi Broken,
    No, you can't do that directly within javascript.
    You can, however, use Ajax to make the call back to a page process that retrieves the fullname value and returns it to your page.

  • PL/SQL Javascript Function Call

    Can anyone offer some help on this? I am attempting to get a javascript tool tip to work on an application I am developing. I have developed a line calendar using PL/SQL outputting HTML. When I embed a javascript function into my PL/SQL htp.p function, the javascript appears to go a little crazy. Here is an example of my code:
    "htp.p('<td onMouseover="ddrivetip("Yahoos Site", "yellow", 250)"
    onMouseout="hideddrivetip()">Yahoo</td>')
    I have tried a few iterations, using different javascript, and I always get the same result. The double quotes used in the onMouseover and onMouseout function calls are a result of PL/SQL not liking single quotes. The entire code for the tooltip can be found on dynamic drives page:
    http://www.dynamicdrive.com/dynamicindex5/dhtmltooltip.htm
    The CSS and javascript code is placed as appropriate in the HTML page header. Am I missing something on the htp.p command?

  • Call javascript functions from PL/SQL

    Hi !
    I just want to know if it is possible to call a javascript function from a PL/SQL procedure. If yes, anybody can explain me the syntax ?
    Thanks
    Chantale

    You can call Java Script - kind of.
    PL/SQL has a "web browser" called UTL_HTTP. It allows you to make HTTP calls to a web server. This includes a function that can be used from SQL too (with a size limitation).
    Example:
    SQL> select UTL_HTTP.Request( 'http://some-web-server' ) as HTML_PAGE from dual;
    HTML_PAGE
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <META HTTP-EQUIV="Refresh" CONTENT="1;URL=http:/some-web-server:7777/index">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <img src="images/Wave.gif">
    Redirecting.. please standby..
    <hr>
    </html>
    SQL>The call to the web browser can be to execute and load, for example, a JSP page.
    However, if the page containts client-side Java script, i.e. code for the web browser to execute, than UTL_HTTP will merely return the contents & code of that page.
    Client-side Java Script requires an engine in the browser. The JS language is used to manipulate the rendering engine of the browser.
    The PL/SQL "web browser" does not have a display device to show a web page. Thus it is without a web browser rendering engine and therefore also cannot execute Java Script either.
