Can Javascript variable store into JSP variable

[Chua Keng Guan]

is it possible to put Javascript variable into JSP variable?

No, this is a frequent misconception and I had wondered the same thing back when I first started with jsp. Simply put, javascript is a client-side technology, so it executes on the client machine, while jsp is server-side, and executes on the server. So you see, there is no way to bridge the divide between javascript and jsp unless you make a trip to the server.

Cannot do this:

<script>
var c = "Acme Unlimited";
<%
String company = c;
%>
</script>
 

You can do this:

  
<%
String company = "Acme Unlimited";
%>
<script>
var c = <%= company %>;
</script>
