{
return str_arg.substr(1,1)

What is this function? If it's supposed to be executed on the server, it should
be enclosed in <% %> delimiters. If it's supposed to be executed on the client,
it should be enclosed in <script> </script> tags *and* it can't be called by
your server-side code later on. As it is now, the code is simply an anonymous
block inside the page's head element, where it's invalid markup.

But, how can I pass arguments to other functions, which
may be outside of <% %>?

You don't have a function called jsFunction! The 'function' isn't enclosed in
<script> </script> tags or <% %> delimiters; it's just text, not code!

Your server-side code seems to expect a return value from jsFunction. If the
function is supposed to execute on the client, you can't do this. Code on the
sever executes first. The output from this code (including client-side
functions) is sent to the client, where it is parsed. Only then do client-side
functions exist as executable code--after the server-side code is destroyed!
