Pass a JSP variable as parameter to javascript function

Question

I have a function defined inside the script tags of head.(in a JSP) I want to declare a string variable in the JSP and pass it as a parameter to this function

Answer 1

If you want to avoid scirplet, you can use expression language by putting it between single quotes.

onclick="pagetype('${uname}')";

without the quotes, it tries to look for a variable with name same as the value of uname.

PS: Used the chrome/firefox dev-tools debugging to find out what's going wrong.
