<Script language="JavaScript">
function test( x )
{
<%
int num = x;
num = num * 2;

v.value = "<%out.print(num);%>";

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.

 

 

Hai,
i dont think so, that is not possible, u can pass jsp variable to javascript,through hidden fields vice versa is not possible

 

 

You can hard code. But you cant pass the variables value.
The only way is to submit the form. And get the data as part of HTTPRequest(request.getParameter()).

The reason is JS runs in your browser. And servlet i.e compiled JSP runs server side..

If its possible why do we need to submit the form :-)
Thanks

 

 

If I have to submit the form to get the data as a HTTP request then how is the javascript function looks like?

This is urgent & needed now.

HI

I need to get the name of the text box submitting the data and I need to get the value as well. So I wanted to do the same as this guy by making a JSP variable equal to a JavaScript one. But now that I know I cant how can I get that information into the JSP??

Heres the code:

<script language = "Javascript">
function findElement() {
for(i=0; i<document.forms[0].elements.length; i++){
if(document.forms[0].elements[i].type == 'text') {
var elName = document.forms[0].elements[i].name;
var elValue = document.forms[0].elements[i].value;
// Display element name and value
//alert(elName ' = ' elValue)
<%
String elName = elName;
System.setProperty(%>elName<%, %>elValue<%);
%>
}
}
}
</script>


Any help would be appreciated. Thanks
