Your current code requires the form to have name not id, so have such form tag:
<form id="myform" name="myform">
To save yourself such trouble though, you can pass reference to the button when calling the function:
<input type="button" ... onclick="calljsp(this);" ...
Then have such function:
function calljsp(oButton) {
var fform = oButton.form;
fform.action = "result.jsp?name=jill&sex=f";
...
This way the name doesn't matter.
In your function calljsp()
use
var fform = document.getElementById('myform');
instead of
var fform=document.forms["myform"];
