Pass a foreach JSP variable as parameter to javascript function

Question

I have the following code sample which was written in the JSP. But it is not working. I have tried that code snippet from the following links. But it didn't help me to solve the problem.

Pass a JSP variable as parameter to javascript function

Passing Jsp variable to javascript as a function parameter

< c:forEach items="${items}" var="item">

   <div onclick="myOnClick('<%=item%>')">${item.title}</div>

< /c>

function myOnClick(item){
    console.log(JSON.stringify(item));
}

Actually I am getting an error in the eclipse that "item cannot be resolved to a variable" for the JSP code.

I tried the below one code

      <div onclick="myOnClick(${item})">${item.title}</div>

It was throwing "Syntax error:illegal character" error.

Need help to fix this issue. Thank you.

Why use <%=item%> instead of ${item}?? Anyway, what you insert is a string (you even quoted it with '), which is retrieved by calling item.toString(), so what is it you expect that stringify() call to do? I mean, it's already a string, and very likely not a JSON string, unless you implemented toString() to return JSON. — Andreas

Actually I am getting an error in the eclipse that "item cannot be resolved to a variable". That is my problem. That method myOnClick() is a temporary method. Don't concentrate on that method implementation. I was asking about the JSP code — veerababu

I tried ${item} also. It was throwing "Syntax error:illegal character" error — veerababu

On the ${item} when ${items} is working fine on the line above?? I find that very hard to believe. Or are you now talking about the web browser, not the JSP (because you forgot the add the ' quotes)?? — Andreas

I found the answer by my own from the following link.

How to access a java object in javascript from JSP?

That is what exactly I was doing in the code. I am getting the Java objects and I am mapping them to the HTML. Once they mapped I wan unable to access them from javascript. But in the above link they have provided the solution to the problem. So we have to call a web service to get the actual object. Thank you @LeleDumbo for providing the answer.
