Instructions on how to pass a parameter from a servlet to a JavaScript function

I'm trying to pass a parameter value from a servlet into a JavaScript function. Here's my Java code:

double nota = rs1.getDouble(1);
request.setAttribute("nota",nota);

This is how I am attempting to call it in the JavaScript code:

<script>
rate (${nota})
</script>

However, I'm encountering the following error message:

Multiple annotations found at this line:

- Syntax error on tokens, delete these 
tokens
- Syntax error on token(s), misplaced 
construct(s)

Can someone please assist me with this issue? I'm new to working with JavaScript. Thank you.

Answer №1

Include "" : 

<script type="text/javascript">
        determineGrade("${nota}"); 
</script>

Answer №2

To incorporate dynamic values, you have a couple options:

<script> var rate= "${nota}"; </script>

Alternatively, an input hidden field can also be utilized.
