Call function javascript on html button onclick, passing param ASP

Question

I'm using node, i passed a param like this:

res.render('page.ejs',{"product" : product });

product is JSON.

In page.ejs I have to call a javascript function passing product like parameter: <button onClick='add(<%product%>)' > add </button> But,in add function, prodotto is undefined. How could i do?

Thanks

Answer 1

Try <%=product%> instead of <%product%>
