Using Javascript variable in JSP

I m setting a variable named btn to the value of the button which was clicked but the problem here is that i m nt getting its value whn i want to set it to a request.setAttribute() method.

> Yes... nw i get the prob... thanx yaar .... bt cn u
suggest me wht cn i do fr this situation
My first suggestion, beyond all others, is to use real words. Your writing is practically unintelligible.
Please make the extra effort to write out words such as "now", "problem", "thanks", "but", "can", "you", and "for" (I have no idea what "yaar" means). The extra keystrokes won't cost much in the way of time, and the enhanced clarity will be appreciated by those communicating on a forum with international readership. Also, it will give the appearance that you take your question seriously, which will in turn make your question look more interesting to answer.

Using JSTL variables in JSP or Javascript. Possible ?

Hi All,
Is it possible to share or use the variables which are declared are used by JSTL in JSP expression or scriplet code and in Java Script.
Example:
This Works:
<fmt:set var="test" value="JSTL" />
<fmt:out value="${test}" />
But, this gives error:
<% out.println(test) %>
And passing the value of variable 'test' to Java Script code also gives error.
How to use JSTL variables in JSP and in Javascript ?
Yours,
Sankar.B

By default, JSTL variables are kept in servlet
attributes. Default is to store it in the page
context. You can make it request/session/application
scope as required by an attribute of the set tag.Hi there,
Can anyone advise how to access JSP variables in JSTL?
Can it be done as the same method through request/session/application scope?
Thnks...

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 pass javascript variable to jsp function

i want to check which table header (that is <th> in html )is clicked and based on that a jsp funtion do a query in database and should show records in sorted way according to which column head is clicked.
Table is created in html.
My function is
Vector varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
<table border="1">
<th ><label onClick="<%SelectedColumn="workcase_id";%>">Workcase Id</label></th>
<th><label onClick="<%SelectedColumn="status_id";%>">Status</label></th>
<tr><td>etc</td></tr>
</table>

im using bean for business login, following mvc model,and i think mvc is one of good design practice to use.
<jsp:useBean id="workcaseid" scope="session"class="beanFiles.SearchWorkcaseId" />
varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
just tell me whether it is possible to pass javascript variable to jsp variable or not.i can do it by using hidden input type,using form and submit button.

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

Hi all,
Thanks for your quick response.
So u are right that we can not call javascript variable
in the same JSP. and pass them to the bean class.
So what I did --- I get java script variable in another JSP using
request.getParameter(); and then redirected to previous JSP.
and I have solve my problem.
Actually I had to call bean class and pass varible to the bean
method but I was getting the same problem that I disscussed but now it
has been solved.
Thanks again for participation

Passing struts-tag value to java / javascript variable in JSP

Hello all,
Im trying to pass the value got from the struts-tag to the java variable in the Jsp. However Im not able to get the o/p. Can u guys help me on this pls...
<logic:notEmpty name="TreeBean" property="list">
    <logic:iterate id="Type" name="TreeBean" property="list" indexId="i">
     <br/><bean:write name="Type" />
    </logic:iterate>
</logic:notEmpty>Here the list can be populated in the jsp page. However i want the values into jsp list. Im not able to populate the same..
<% List jspList = null;
%> I want the values into the jspList variable for further processing. Can u guz pls help me on this....

Which do you want it in?
A java variable for use in <% scriptlet code %> or a javascript variable for use on the client end?
scriptlet:
<jsp:useBean id="TreeBean" type="java.util.List" class="java.util.ArrayList" scope="?????" />
Having scriptlet code on the page is considered bad coding style.
What is it you are trying to accomplish by making the value accessible?
What are you trying to do in java / javascript that can't be done with JSP tags?

How to use javascript variable in BSP/ABAP and vice versa

Hello Experts,
In IC WEBCLIENT, there is a view.In the view.htm i want to fetch the screen resolution and as per the resolution i want set the width of that view.
1, I wrote the below javascript to fetch the screen resolution.
   Can i use a notmal ABAP variable inside the javascript? and   If i use can i access that variable after the javascript.?
   Can i assign a javascript variable to a nrmal abap variable??
   The code sample is like :
Start of javascript
   if (screen,width == 1024 )
     lv_width = 500 "lv_width is an ABAP variable.
else
    lv_width = 700
**END OF JAVASCRIPT
   **Now i want to use lv_width to assign to a table view attribute(Width)
<crmc: tableview..
                width = <%= lv_width >
the code is not giving any error. But the problem is that lv_width is not giving the correct value, its getting initialized to initial value...
Requesting the experts to please provide some suggestions/solution for the above issue.
Thanks and Regards
Sudhansu

Hello Sudhansu,
First of all there was a little mistake at my previous answer:
you got lw_width = 700
because at Server Side you have following code:
lw_width = 500.
lw_width = 700.
but if you were writing your code like this:
<%=lw_width %> = 700.
then you will get the result that I was talking about : 0 = 700
Sorry for the mistake
Now for your question:
if you want to get a value from the server and assign it to JScript variable you should write like this :
var aaa;
aaa = <%=lw_width %>;
this code assign the server variable lw_width value into aaa JScript varible.
I'm not sure what exactly you want to do but look at this link:
http://www.pageresource.com/jscript/jscreen.htm
to get the idea how to get and use Screen Resolution variables at your JScript code.
Good luck

Sharing JavaScript variables with JSP

Hello everyone --
I was pretty smug when I thought that I could store JavaScript variables in a hidden input parameter for the JSP to pick up.
When I run:
<script language=javascript>
if(confirm("Do you really want to delete this user?"))
document.write("<input type=hidden name=confirmusr value=true>");
else
document.write("<input type=hidden name=confirmusr value=false>");
</script>
<b>User input was <%= request.getParameterValues("confirmusr") %></b>I get: User input was null
I thought that at first I needed to escape the " in write(), but that wasn't it. Does anyone know why it seems that JS is not creating that hidden input type? Thanks in advance for any suggestions, Kwj.

You can do it this way:
<form name="myForm" etc etc>
etc
<input name="confirmUser" type="hidden" value="">
etc
<script language="javascript">
function onClickHandler() {
if (confirm("Do you really want to delete this turkey?"))
document.myForm.confirmUser.value = "true";
else
document.myForm.confirmUser.value = "false";
document.myForm.submit();
</script>
etc
<input name="button" type="button" value="Delete Turkey" onClick="onClickHandler()">
etc
</form>
etc etc etc

Using javascript variable in spry if statement

is it possible to put a javascript variable in to the spry if
statement to test?
like <div spry:if="javascriptvar == {ds_RowNumber}"....
thanks.

Hi rogerfreak,
When the region processes a spry:if, it simply takes the
value of the spry:if attribute, replaces all of the data references
in it with real values from the data set and then evals the result
(executes the string).
So you can do something like:
<script>
var ds1 = new Spry.Data.XMLDataSet("foo.xml", "/foo/bar");
var gMode = 5;
function GetMode()
return gMode;
</script>
<div spry:region="ds1">
<ul spry:if="gMode == 5">
<li spry:repeat="ds1">{name}</li>
</ul>
<div spry:if="gMode == 12" spry:repeatchildren="ds1">
{name}
</div>
</div>
In the example above the list markup will be written out if
gMode is 5, but if it is 12, it will write out the div markup.
You can also call functions:
<div spry:region="ds1">
<ul spry:if="GetMode() == 5">
<li spry:repeat="ds1">{name}</li>
</ul>
<div spry:if="GetMode()== 12"
spry:repeatchildren="ds1">
{name}
</div>
</div>

How to use a variable of jsp custom tag in my java code?

hi folks,
i got a folderList tag like this:
ArrayList list = new ArrayList(20);
%>
<foo:folderList path="${attributes.newsPath}" var="year" contentType="folder">
<%
          list.add(${year.contentEntryName});   // of course, this doesn't work
%>
</foo:folderList>I think, its clear what I want to do. I am just wondering how I can use my Variable "year" in the Java code between <% %>...

<% list.add(year.getContentEntryName()); %>
You have to have defined in the custom tag that "var" relates to a scripting variable that you want defined.
<tag>
<variable>
    <name-given>var</name-given>
    <variable-class>myPackage.myClass</variable-class>
    <declare>true</declare>
    <scope>NESTED</scope>
</variable>
</tag> Cheers,
