Pass parameter from javascript to backing method

Hello professional ,
i have an ADF (JSF page) there is news bar on it when the user click on any news link i want to pass the news parameter to backing method .
The problem is how can i pass javascript value to commandLink jsf tags to setActionListener sub Tags:
<tr:commandLink id="openNewsActionLink"
text="#{screenLabels.NEWS_DETAILS}"
inlineStyle="display:none; visibility: hidden;"
action="#{publishedNewsBackedBean.openNewsDeatilsAction}">
<tr:setActionListener from="6"
to="#{publishedNewsBackedBean.selectedID}"/>
</tr:commandLink>
i want to pass the from value from java script code how can i do it and if i can not do it directly what is the work around for it.
Regards

Hi,
assign an ID to the inputText and use the JavaScript Document Object Model to access it. Also use a good browser with good DOM source viewer to browse the HTML page your JSP creates at runtime Firefox and Chrome have good source viewers.
there are truckloads of JavaScript examples on the Internet.
Or as Frank said if you get the setActionListener working properly you can easily copy a value from one input value binding to another.

Passing Parameter from javascript to Servlet

hi,
I have 2 list boxes in my Jsp page and values for these list boxes are preloaded . These things are to be carried out using javascript onload() function.
So now i want to pass the selected parameters from both the list boxes to servlet and have to display the corresponding resulting datas in same JSP page. if i submit the form then values selelcted by the user will reset because the form has onload() function. then i thought hidden field will solve my problem. but its giving error like nullpointer exception.
so please tell me how to achive this.

When you right a new Option(...) line in javascript, there are three parameters you can give:
Option("text", "value", selected);
How you make use of this depends on how you move from the servlet back to the JSP.
So for example, if you are doing a response.sendRedirect in the servlet, you will either have to add a parameter back to the url you are re-directing to, or add the value to the session. (I like the session method myself... hides it from the user)
//in servlet
public void doGet(...)... {
    String country = request.getParameter("country");
    String state = request.getParameter("state");
    //... Do Stuff ...
    HttpSession session session = request.getSession();
    session.setAttribute("country", country);
    session.setAttribute("state", state);
    String sendTo = response.encodeRedirectURL("theForm.jsp");
    response.sendRedirect(sendTo);
//... The JSP might look like this now...
//Get the selected values from the session:
<%
    String countrySelected = (String)session.getAttribute("country");
    String stateSelected = (String)session.getAttribute("state");
%>
<html>
<head>
<script type="text/javascript">
/* Use this to store the values for states in JavaScript */
var state2DArray;
/* Javascript function to set up values for the states and countries */
function initSelects() {
    <%
      /* This is JSP scriptlet code to get the country list that we need... */
      List countries = (List)application.getAttribute("countryList");

    countrySelect = document.form.country;

    //We are going to call the fillInStates now at the end of initSelects so the initial
    //values are passed on to the states...
    fillInStates(countrySelect);
    <%

Can't pass parameter from HTML form of multipart/form-dta type to JSP

How can I pass data successfully from this form to
JSP?jsp's are not meant to read such amounts of data. this (= uploading) is a typical task for a specialized servlet. there you have full control over input and output. if you need to, you can still forward to a jsp after processing in the servlet.
How can I pass data from JavaScript to JSP???? i'm not sure what exactly you mean. normally you put it into an url and submit it.

How to pass parameter from 1 stored procedure to another stored procedure inside crystal report

Hi
I have several stored procedure in my Crystal Report. I am wondering if it is possible for me to pass a parameter to one of the stored procedure and to use the result of that stored procedure E.g. CustomerCode. To another 2 stored procedure to generate the report dynamically?
I have 3 stored procedure
The 1st one is used to gather information and process the calculation
another 2 stored procedure is used for generate the graph and both of them required to take 2 parameters. The 1st stored procedure will require 1 parameter (E.G. Reference Code) and will return a set of information including the data that could be use on the other 2 stored procedures.
After I added these 2 stored procedure, it requires me to pass 3 parameters to the report. I would like to know if I could only pass the Reference Code for stored procedure 1 and use it to retrieve the information for the other 2 parameter?
Thanks in advance
Chi

Hi Chi
To pass parameter from 1 stored procedure to another stored procedure, you will have to create sub report. In your case you will have to create 2 sub reports for 2nd and 3rd stored procedure and link those sub reports with the main report using Reference Code field in order to pass the values.
After creating the report when you will refresh the report, it will ask 4 parameters, one parameter for main report, one for the first subreport and two for second subreport to fetch the data correctly.

Master-detail relationship - passing parameter from form to form

Hello.
I have a question about master detail relationship.
In first form we have master-detail relationship.
Example on dept, emp tables:
We query dept (master), so we can get one or many emp (detail) records. Then we have a third table - tasks. Tasks table (detail) can have many records for one employee.
Tasks table is in another form, which is called with call_form built_in. So we pass a parameter from master to detail - parameter empno. Because of that, we can only see tasks for one employee and can't navigate to another employee. This is normal.
Now comes the question.
Is it possible to call a form (with tasks table) with deptno parameter (so we can navigate through all employees with that department), but first show employee that was last used in first form?
Example of our goal.
Master: deptno = 20
Detail: navigate to JONES employee
Call new form (tasks)
Tasks for JONES employee are first shown
Can navigate to another employee - without requery
Is this possible?
If we pass deptno parameter, we can navigate through all employees - but must navigate to the employee we last used in first form.
If we pass empno parameter to second form, we see last used employee but cannot navigate to another employee without requery.
Hope you understand my problem.
Thanks.

Hi
yes you can pass parameter from one form to another.
In your master detail form set the trigger when-new-instance and there define the global variable like
:GLOBAL.G_CIRCLE_ID := NULL;
and in your task table set the trigger when-new-instance and there define the global variable like and also write this code
:GLOBAL.G_DIVISION_ID := NULL;
IF :GLOBAL.G_CIRCLE_ID IS NOT NULL THEN
     GO_BLOCK('DIVISION');
     SET_BLOCK_PROPERTY('DIVISION',DEFAULT_WHERE,'CIRCLE_ID ='||''''||:GLOBAL.G_CIRCLE_ID||'''');
     EXECUTE_QUERY;
END IF;
:GLOBAL.G_CIRCLE_ID := NULL;
now you maintain your trigger according your need.

Passing data from JAVASCRIPT to SAP database

Hi Experts,
Is it possible to connect or access RFC function module through JAVASCRIPT? I want to send data from JAVASCRIPT to SAP database table.
Is it possible to pass data from JAVASCRIPT to SAP database table?
Thanks in advance.
Regards,
Arindam Samanta.

OData services can be one option to achieve this.
Another possibility can be use of Generic REST enablement with SAP NetWeaver Gateway.
If you are not considering Gateway at all, then A JSON adapter like the one mentioned in JSON Adapter for ABAP Function Modules can be handy.
