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???

• Do you really need to wrap 'sel' in <%= %>? – Ben Gulapa Commented Jul 15, 2013 at 11:27

• Or would you want to use the the function argument sel to call a method on the back-end? In that case the principle applied is the same as stackoverflow./q/13840429/1331430 – Fabrício Matté Commented Jul 15, 2013 at 11:33

Because javascript does not understands jsp scriptlet,

Try,

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

I don't know where you found this <%= sel %>, but its not the native JavaScript style of doing it. Try this:

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