Assigning return value of a javascript function to a variable

Question

hi.
I have a javascript function which returns string.
I wanna assing return value of that function to variable.
for example:
<script>
funtion writeMe()
var ex;
ex="try"
return ex;
</script>
Then in body of JSP page. I wanna do something like:
<% String st;%>
Now I wanna assign the value that returned from writeMe function ("try") to st string.like:
<%st= writeMe();%>. but of course it doesn't work. how can I do that?

Answer 1

thnx. but actually what I want to do is sending some values produced by javascript to a barchart object. is it impossible too?
I mean my script function returns something like "100, 200, 300". I wanna pass that values to barchart. when I want to add aplet tag to jsp code instead of writing:
<param name="s1_value" value="100,200,300">
I want to write somethin like:
<param name="s1_value" value="myscriptfunction()">
is it possible in JSP? I saw an example like this in asp. it was like:
<param name="sampleLabels" value="<%call func1()>">. but in JSP it seems like call tag doesn't work. Is it possible in JSP?
