How to get javascript variable in jsp variable

Hi all,
i have a variable str in my javascript function
var str = somevaluei want this str value in jsp variable in the same page...
how can this be done..???
any ideas...
Thanks

I dont know if its possible or not.
Actually it depends on what do you want to do with the variable.
as far as assisginng value to the hidden variable is concerned it can be done this way.
<% jsp code
String hiddenVar = "";
%>
< html code
<input type type = "hidden" name="hidden" vale="<%=hiddenVar %>"
html ends>
while in js function you can assign vale to the hidden variable which will ultimately assign value to the JSP variable as follows.
var str = "value";
document.form_name.hidden_field_name.value = str.
hope this hepls.

     String parameterValue = " ";
     String parameterName = " ";
               while (parameters.hasMoreElements()) {

How to get the value of a variable defined in javascript in JSP

how to get the value of a variable defined in javascript in/through JSP????

In Javascript you can use the DOM to access the input element and set it's value before submitting the form. Then it's value will just be passed.

Passing JavaScript values to JSP variables

Can any body correct the follwing code
<Script language="JavaScript">
function test( x )
<%
int num = x;

%>
v.value = "<%out.print(num);%>";
<input type="button" name="b" value="test" onClick="test(5)">
<input type="text" name="v" value="0">
In short, I am trying to pass JavaScript value to JSP variable. I hope that it is possible to do that. If it is possible then how can I do it. I want to assing the variable x passed to the JavaScript function called test to the JSP variable called num.

Thank you for your reply,,,
I think then the only way to do it is to post the
value on the server and then use request.getParameter
method in jsp code
but the question now how can I post values to the
server using JavaScript without reloading the pageyes... you can to it by create a new popup window which will submit the value to server after page was loaded... then, server return a value to the same window in html/jsp page which then using javascript to set it back to the opener and close up the window... however, this is not a good choice unless you have no other alternative...
>
There is other possible solution
if I can get the text field value from the same page
without reloading it that would work fine and will
solve my problem, is it possible?yes... you can get the value from the textfield...
for example :
function showValueInTextField()
alert(document.forms[0].elements["mytextfieldname"].value);
>
My final question> can jsp change things on the same
page without reloading it. I mean can it work like
JavaScript so that I can use it's internal functions
instead of using java script :S
not really know what you trying to say here...

I want to assign the value of a Javascript variable to JSP Variable

I want to assign the value of a Javascript variable to JSP Variable .. for example :
<%
Bla Bla Bla
%>
<script>
var JavaScriptVariable="hello"
</script>
<%
String JSPVariable=// The Value of JavaScriptVariable ;
%>
How can i do that ??
Thanks

>I want to assign the value of a Javascript variable to JSP Variable
cannot be done.Friend try to understand concepts properly Javascript is always excuted by the browser @clientside where as JSPCode is executed Websever(ServletContainer) @serverside.Through you are combining JSP Code blocks(Tags,Expressions,scriptlets...) & javascript under a single page webserver can only identify what is their under JSP Code blocks.
Hope this could be an appropriate answer for your question.
However,you can as well submit a request by encoding your URL with request parameters and the submit to the page and then collect it using request.getParameter(name).
But under a single context state it is not possible

For example, I would like to take quantity field in inventory audit report. And when I put my cursor in

T1.[Dscription] as 'Deskripsi', T1.[Quantity] as 'Quantity', ((T1.[LineTotal])/(T1.[Quantity])) as 'Harga

How can i assign a Javascript variable to JSP variable

Hi guys
how i can assign a javascript variable to jsp expression.,
e.g.,
<input type = "button" value = "Add more" onclick = "return submitform1('<%=s%>')">
function submitform1(String s)
      var s1 = s
document.form1.action = "../intimation.do";    /* Here i want to pass the value s1 to jsp or servlets without using hidden fields and Query string*/
       document.form1.submit();
      return false;
/* i want to pass the values thru session whether it is possible */
pls give sample code

You don't have the session.
All you have is HTTP.
The only way to communicate from the client to the server is via an HTTP request. The only way to send a value like that is with a parameter.
Using a form with method="submit" as mentioned will pass the parameters without displaying them in the url bar (is that what you wanted?)

How to get record count value in variable

Hi,
i wanted to capture record count value in the variable?
Please let me know how to do this?
Thanks,
jag

To determine count of records, use: count(field_name) -- replace field_name with your appropriate field.
You don't have to save the record count value in a variable. You can directly use the condition <?if: count(field_name) > 0?> display table <?end if?>
If you want to store it in a variable: use <?variable:record_cnt;count(field_name)?>
Take a look at this post that uses a record count: https://blogs.oracle.com/xmlpublisher/entry/no_data_found

How to get table headers in jsp page

how to get table headers in a jsp page. whether it is possible using javascript or is there any other way.

File=new FileLog("f:/WebServiceTrace/trace2.%g.log", 800000, 10,                                        new TraceFormatter());
The above code specifies the path for your log file.
Then add this file as a log location and then log the traces. For this you can use the following code like:
Location location=Location.getLocation(className);
          location.addLog(file);
          location.setEffectiveSeverity(Severity.ALL);
          location.entering(methodName);
To Create j2ee apllication
In path new-j2ee-jsp to create JSP's can only be used for J2EE applications.
So as you are using this in Portal Application, this does not work.
You can test this bahavior by creating a new Web Application (New-Project-J2EE-Web Module Project)
In this Web Module Project, try creating JSP, this will work.
So dont use new-j2ee-jsp to create JSP in Portal Application instead use New-File and name the file as jsp.

How to get result from another JSP file?

I have to write a jsp (my.jsp) to get information from another jsp file (other.jsp).
The other.jsp return integer value (0 / 1) so that user can tell if certain service is available or not. And in my.jsp I need to collect such result and other information from a text file to make up of a XML string.
How can I call other.jsp to get the result? Thanks a lot.

Hi, I think I didn't describe the problem clearly
enough. In fact, there is a JSP file, and if our
database is currently connected, the JSP will return
value 1, otherwise, it will return 0. My java program
need to get that result, and then form an XML string,
and send the string back to the client. I'm just
wonder how can I write such a program to read result
from JSP file. Thanks a lot.Why is this function implemented as a JSP file? It should be implemented as a bean. It would be simple to get the information you require from that bean.
