Get Javascript Value in a JSP page

Let's say this is my javascript function in a html page
.<head>

function getFields(){
if (row >= 0){
for(var i=0; i<costForm.elements.length; i++){
if(costForm.elements.type == "text" || costForm.elements[i].type == "hidden"){
dynTableFields[i] = (costForm.elements[i].value)? costForm.elements[i].value : "";
if(costForm.elements[i].type == "select-one"){
dynTableFields[i] = costForm.elements[i].selectedIndex;
</head>
How do i get the costForm.elements.length value in another jsp page. Coz the html page has dynamic rows by the users. and i need the values in the jsp page to know how many rows the user created.
using normal request.getParameter("costForm.elements.length") doesn't work

request.getParameter() will only get data that's been submitted thru a form or the query string of a URL. You'd have to record the length in a hidden field to read it on the back end, and then you can't just loop thru the fields like that in JSP on the server anyway, unless you have all fields named with a prefix and number, like: field1, field2, field3, etc.

Hi,
I have developed a JSP, having two split fields seperated by some buttons..The sample code for the same is like this..
(Only the required portion is included)
<script>
function reloadPageOK() {
document.product.method="post"
document.product.action="./TheSamePage.jsp?status=OK"
document.product.submit()
function moveValue(from,to) {
if(from.selectedIndex>=0) {
var text=from[from.selectedIndex].text
var length= to.length
to[length]=new Option(text,from.value,false,false)
from.remove(from.selectedIndex)
function moveAll(from,to) {
if(from.length>0) {
var menutext="";
var i;
var len=from.length
for(i=0;i<len;i++) {
from.selectedIndex=0
menutext=from[0].text
var length= to.length
to[length]=new Option(menutext,from.value,false,false)
from.remove(from.selectedIndex)

The page is working fine. That is we can move the values in the left field to right as single or group.After submitting I need to get the values in the left & right fields respectively.
I have used the method
request.getParameterValues("lstProviderLeft");
and pointed this to an array of strings,but it returns 'null' .
How can I solve the above problem....Post your comments on this issue
Thanking u

probably the request.getParmeterValues will not work in this case as the name of the 2 select boxes are different....
You can do this utility by using Javascript....concantinate the values of the 2 select boxes and put the concantinated strings (with a delimiter) in two hidden fields and capture the same fields in the target JSP/Servlet.
I have modified ur code...have a look...

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:
<html>
<body>
<h2 align="center"><u><b><span style="background-color: #FFFFFF"><font color="#C0C0C0" face="Comic Sans MS">Leave

        </table>
        </td>
    </tr>
</table>
</form>
</body>
</html>{code}
this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

How to get the value in one JSP page to another?

Hi,
I have problems in passing the value around in JSP. I have two JSP pages as below:
test1.jsp
I try to get the vaule from my textbox by using:
String strUser = request.getParameter ("strUserName");
Then i print out by using: out.print(strUser); then i can get the value and put on my page (For example, i get ABC on my page).
test2.jsp
Next, i want to get the value from strUser (which mean that the one i already display on page in test1.jsp, ABC) to insert into my table by using INSERT INTO statement. Then i try by using
String strUser1 = request.getParameter ("strUser");
Is it possbile for me to do that? I cannot get anything to insert into my table. Then i tried out.print(strUser1); then i found that i get NULL value.
Could you please give me some guidance?
Thanks you very much for any advise you may give me.

Could you please advise?
Thanks you very much for your time and any consideration you may give me.

Passing values to the JSP page - Urgent

Hi all,
I have to pass the user id value to the JSP page. I have written the following code in the doInitialization() method
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
IAuthentication ia = UMFactory.getAuthenticator();
IUser portalUser = ia.getLoggedInUser(request.getServletRequest(), request.getServletResponse(false) );
s = portalUser.getUniqueName();
IPortalComponentSession componentSession = ((IPortalComponentRequest)getRequest()).getComponentSession();
Object o = componentSession.getValue("myEvents");
myEvents = (LoadEvents)o;
//myEvents = (LoadEvents) myContext.getValue("myEvents");
myEvents.setUserId(s);
myContext.putValue("myBeanName", myEvents);
I have also defined myEvents as a bean in my JSP page with scope APPLICATION. But I get User Id as "NULL".
Thanks in advance.

How do I get the URL of a jsp page?

I have a jsp page which has a link to a servlet page, in the servlet page, I want to get the URL of the jsp page.
I tried to use request.getHeader("referer"), it seems like if it is a link in the jsp directly lead to the servlet, it works, but if the link calls a javascript function which opens up a window runing the servlet, it is not working. I have to do the second way, so it is not working by doing request.getHeader("referer")
I tried to use javascript "location.href", I get the whole url by alerting the url in the jsp page:
http://localhost:8080/pos-webapp/serv/qt_old?currentpage=portal&bcd=ABC123&pnm=P1001830&prnm=1&psd=236863.0&ln=01&sln=NYPPA&stp=2.1&stt=A&_POSID=1F8464122ADAF4EEC9B1A94C286EB252
then I pass this url when calling with my servlet, in the servlet page, when I do request.getParameter("url"), the url is actually cut off like this:
http://localhost:8080/pos-webapp/serv/qt_old?currentpage=portal
anything after &pnm is cut off, anyone has any idea?
Thanks in advance.

Thank you.
but how do I put encoding in the javascript code? do I need to decode in my servlet page?
here is my code in the jsp page:
linkset[3]+='<div class="menuitems">Email Diagnostics to AutoOne</div>'<%
function emailDiagnostics()
win = window.open("/pos-webapp/serv/email_diagnostics?url=" + location.href + "&browser=" + navigator.appName, "emailDiagnostics",
"width=350, height=140, resizable=no, scrollbars=no, toolbar=no, location=yes, directories=no, status=no, menubar=no, copyhistory=no, left=450, top=300");
win.focus();
}

How can I get the "pageContext" object in jsp page?

Hi everyone:
I want to get struts's DataSource object in jsp page.So I should get the PageContext object in jsp page.My code is:
///////////////////datatest.jsp///////////////////////////////////
     DataSource ds=(DataSource)pageContext.getAttribute(Action.DATA_SOURCE_KEY);
     conn=ds.getConnection();
          stm=conn.createStatement();
          rs=stm.executeQuery(insertsql);
Is right?But I get the "NullPointerException" error in Tomcat.The connection pool in struts-config.xml is:
<data-sources>
<data-source key="mydatasource">
<set-property property="autoCommit"
value="false"/>
<set-property property="description"
value="MyWebSite Data Source Configuration"/>
<set-property property="driverClass"
value="org.gjt.mm.mysql.Driver"/>
<set-property property="maxCount"
value="4"/>
<set-property property="minCount"
value="2"/>
<set-property property="password"
value="qijiashe"/>
<set-property property="url"
value="jdbc:mysql://localhost:3306/myweb"/>
<set-property property="user"
value="lyo"/>
</data-source>
</data-sources>
I can query the database in servlet.
I think the method that I get the context is not right.Had someone get the pagecontext in jsp page?help :(

Sorry I forgot that I had change the code:
DataSource ds=(DataSource)pageContext.getAttribute(Action.DATA_SOURCE_KEY);
     conn=ds.getConnection();
          stm=conn.createStatement();
          rs=stm.executeQuery(insertsql);
to the code:
DataSource ds=(DataSource)pageContext.getAttribute("mydatasource");
     conn=ds.getConnection();
          stm=conn.createStatement();
          rs=stm.executeQuery(insertsql);
mydatasource is the struts datasource in "struts-config.xml". I couldn't work

How can I share values between different jsp pages?

Hi,
I'm doing a jsp, bc4j application (JDeveloper 9.0.3), and I need to share some values between different jsp pages. To do this,
I have used the tag <jsp:usebean.....></jsp:usebean> in this way:
on pageone.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
on pagetwo.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
and so on, in order to refer to the same instance of the class "Parameters".
After deploying, the application works well only if the client is the same pc where the AS resides, otherwise the variables of "Parameters" are null.
Please, could you help me?
Thanks
Nunzio.

I am seeing an indication on 9.0.3 that static includes are not static, but instead always dynamic. The compiler generates a call to the included page, and doesn't include the content in the calling page as it should.

getParameterMap() returns a Map[1] with all parameters; the parameter name is the key and the value is the value of the parameter in the form of String arrays.
You have to iterate over the Map and get values as you see fit. Search for a tutorial/ example/ sample for using Maps. I'm sure you'll find loads that will do a better job at explaining.
