Assign Javascript value to JSP var

[sridhar lakka]

Hi All,
Thanks a lot in advance.
I have some value in javascript and I want to assign that value to a jsp variable.
I know how to assign a JSp value to a javascript variable but I am not getting any idea on this.

I have a code like below
<Script language='javascript'>
var x=5;
</script>
And I want to set this x value in seesion attribute,like
<%
session.setAttribute("XJavascript",x)---this should be javascript value
%>

Regards,
Sree

There is not any direct way to apply javascript value into JSP, because javascirpt run on client side and the JSP is server side language.

the only way I know is by using a hidden fields,

[Amol Nayak]

<%
session.setAttribute("XJavascript",x)---this should be javascript value
%>

This wont compile as x is not defined, Here x should be a java variable( not java script) of type Object.

What exactly are you trying to do, give the scenario, maybe there is some another way of doing it.

As Saif has mentioned, the only way to achieve this as per my knowledge is to use hidden fields along with your form. For e.g.

<input type="hidden" name="hideX" />

then in your javascript set the value as:

<script>
var x= 10;
document.<form name>.hideX = x;
</script>

This should work.
