How to Pass QueryString in window.location.href?

Question

I have written the following javascript function

function getval(sel)
 {
    window.location.href = "Posts?Category=<%= sel %>";
 }

but the value of sel variable is not considered in querystring..

Instead of it, it takes value like following.

...../Post/Posts?Category=%3C%=%20sel%20%%3E

Can anyone help me???

Answer 1

Because javascript does not understands jsp scriptlet,

Try,

window.location.href = "Posts?Category=" + sel;
