Hi all,

Can anybody tell me how to access the Java Script variable in a JSP Java script.

Thanks in advance

The normal way you do. The page is ultimately going to be an HTML, so just use the variable, like you use it normally.

Is this what you want? Or do you want to use the variable 'a' declared in javascript as a java variable in JSP? I do not think that is possible.

Thanks for the reply but I want to use varaible 'a' in JSP as java variable. In my case the variable 'a' is declared outside the function.

<script>
var a = 5;
funtion fun()
{
a = 10;
}
</script>

Either way, it is a script variable. I don't think we can use that as a java variable.

Then is there any way to pass the javascript variable as a request parameter. I think it can be done using HTML also.

Given is the sample code which I am trying, but it doesn't work.

Can anybody suggest anyother alternative. One thing more, I want to pass it using the anchor tags <a></a> only.

This should help you
<html>
<head>
<title>JSP Page</title>

<script>
var a=10;
function fun()
{
var link = document.getElementById("link");
var url = "index.jsp?a=" + a;
link.href= url;
}
</script>
</head>

<body>
<h1>JSP Page</h1>
<a id="link" href="index.jsp" onClikk="fun();">click here</a>
</body>
</html>

You could also update the value of a hidden form field via javascript and then submit the form via POST method if you didn't want to pass the value in the url.
