Need a fast answer... passing javascript variable to jsp page (how to use)
This test application has 3 frames.
I'm assigning a value "stuff" to a variable ("testfield1") in a javascript function ("getTest") that exists inside an html frame (testpage1.html)
Then, I click on the "test submit" hypertext link to pass the value of "testfield1" to the JSP frame (testpage2.jsp) by invoking a function ("getData") in "testpage2".
In function ("getData"), I am passing the variable "testfield1" as a parameter to the "getData" function in "testpage2".
In "testpage2" - in the ("getData" function) I try to assign the value of the variable "testfield1" to another variable called "testfld1".
Then, I try to extract the value of "testfld1" into a variable called "tstfld1" in a JSP scriptlet
....I.E. [ String tstfld1 = request.getParameter("testfld1"); ]
But, the value is apparently not passed successfully, as tstfield1 appears to be "null".
Can anyone explain what I'm doing incorrectly?
The code for this test app is below...
********testpage0 - the parent frame*********
<HTML>
<HEAD>
<TITLE>GlobalView Reports and Trending Menubar</TITLE>
</HEAD>
<FRAMESET FRAMEBORDER="0" ROWS="15%,85%">

return;

document.pageData.submit();
</script>
</head>
<body>

<div id="HiddenForm">
<form name="pageData" method="post" action="testpage2.jsp" target="_self">
<input type="hidden" name="testfld1" value="0">
</form>
</div>
<%
String tstfld1 = request.getParameter("testfld1");
%>
<P> testfld1 = <%= tstfld1 %> </P>
</body>
</html>
parent.frames[2].getData(testfield1); is in testpage1.html
so in the document.pageData.testfld1.value = testfield1; document = testpage1.html( not testpage2.html)
modifying the getData to accept the document object, and refering this object to parent.frames[2].document may help you.
good Luck ....

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">

<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);

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.
Regards,
AgeelThank 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... -
How tp pass javascript variables/arrays to a servlet?
Plz help me in passing javascript variables/arrays to a servlet
Hi,
I am creating table rows & columns containg text fields dynamically as follows:
function addRowToTable()
var tbl = document.getElementById('tblSample');
var lastRow = tbl.rows.length;
// if there's no header row in the table, then iteration = lastRow + 1
var iteration = lastRow;
var row = tbl.insertRow(lastRow);
// right cell
var cellRight = row.insertCell(0);
var el = document.createElement('input');
el.type = 'text';
el.name = 'txtRow' + iteration;
el.id = 'txtRow' + iteration;
el.size = 20;
cellRight.appendChild(el);
Now i am calling function addRowToTable() from jsp page as + key is pressed to add rows dynamically.
So as per rows different textfields are also getting created dynamically with different id & name.
Now i am getting session attributes containing the values for textfields from servlet.
but i am not able to map the values for dynamic textfields getting created?
I want to print values in appropriate fields.
Plz help me. -
Passing javascript values to jsp without refreshing the page
Hi,
How do u pass a value of a javascript variable to the jsp without refreshing the page ?
For example, a file called test.jsp in which a javascript variable x contains value 254. I need to pass the value of x to a method declared in test.jsp(same page).Hi Mona,
when i say refresh i do mean a blink of the browser.
This is a small example i wrote to show you how you can pass javascript varables to JSP variables. If you don't want the refresh to be seen by the user just include this code in a hidden frame on a page and instead of refreshing the entire page, refresh the hidden frame.
i have to say, i didn't test the code so i don't guarantee it's flawless.
if you need an more detailed example just tell me, i'll create one, but it won't be for today :)
<html>

var user = "<%= username%>";
//check if there is a username in the URL
if(user=="null")
//there is no username so we log the person in as a guest
user="guest";
//we refresh the page and set the user parameter to 'guest'
//the parameter now contains the javascript variable 'user'.
//The parameter can be read by the JSP (see the top op this script).
//This way we gave the javascript variabele to the JSP variable
location="login.jsp?user="+user;
else if(user=="guest")
{ alert("Welcome "+user+", I hope you like this site"); }

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
Reply
MarimuthuYou 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?) -
Passing JavaScript value to Jsp
Hi,
Any idea how to pass a value from javascript to jsp page when the page gets load on browser.
I use below code but an event is require to pass the value. Is there any code that pass automatically the value from javascript to jsp.
<html>
<head>
<title>Passing Javascript value to Jsp</title>
<script type="text/javascript" language="javascript">
var scriptVar = "Noy"
var WinNetwork = new ActiveXObject("WScript.Network")
document.write (WinNetwork.username)
document.index.hiddenTextBox.value = WinNetwork.username
</script>
</head>
<%
String jspVar = null;
if(request.getParameter("submit") != null){
jspVar = request.getParameter("hiddenTextBox");
out.println("Jsp Var : " + jspVar);
%>
<body>
<form name="index" onSubmit="index.jsp" method="post">
<input type="hidden" name="hiddenTextBox"><br>
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
Thanks,
~ukbasakJSP/Java runs at the server side, produces a HTML page, sends it to the client side and then stops running.
HTML, containing under each CSS and JS, arrives at the client side and runs at the client side only.
To invoke JSP/Java using HTML you need to fire a request to the server side. That can be either a plain vanilla <a> link, a <form> to be submitted or an asynchronous Ajaxical request.
That said, the use of ActiveX in web applications is discouraged. It's a Microsoft IE proprietaty. With other words, it isn't and won't be supported by all alternative browsers which the other half of the world is using. -

amitindiaHi 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

How can we use java variable in javascript code on JSP page?
How can we use java variable in javascript code on JSP page?
Pls helpThink about it:
JSP/Java is executed on the Server and produces HTML+JavaScript.
Then that HTML+JavaScript is transfered to the client. The client now interpretes the HTML+JavaScript.
Obviously there's no way to access a Java variable directly from JavaScript.
What you can do, however, is write out some JavaScript that creates a JavaScript variable containing the value of your Java variable. -
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

Edited by bpmvasu at 04/03/2007 10:43 PMHi Mariano,
I'm using JSP presentation too. In "Interactive Component Call" active i'm using "Use JSP presentation", but i only can define one instance variable, i need to add more instance variables. In "Advanced" option of this task, i have the argument mapping .. but i don't understand how to use it.
I have a instance variable called "genders" of the type String[Int] (Associative Array) and i'm mapping this instance variable in "Arguments Show In" option of the advanced option of JSP presentation. In JSP presentation i have the code:
<select <f:fieldName att="person.gender"/>>
<c:forEach var="gender" begin="0" items="${genders}" varStatus="status">
<c:choose>
<c:when test="${person.gender == gender}">
<option value="<c:out value="${gender}"/>" selected="true"><c:out value="${gender}"/></option>
</c:when>
<c:otherwise>
<option value="<c:out value="${gender}"/>"><c:out value="${gender}"/></option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>And in my screenflow i have the code:
genders[0] = "Male"
genders[1] = "Female"But when i run my application, i have the error: "The task could not be successfully executed. Reason: 'java.lang.ClassCastException: java.lang.Integer'."

How can I access xml document from javascript whithin a JSP page
how can I access xml document from javascript whithin a JSP page?
I have a JSP that receives an XML document from a JavaBean, so I can access it within the entire JSP, but I need to access it from the javascript inside the JSP... and I have no idea how i can do this.
Thanks in advance!The solution would only work on MS IE browsers, as other browsers do not support an XML DOM.
It can be done, but you would be stuck with using the Microsoft broswer. If that is acceptable, I have some example code, and a book recommendation.
