Hi,
I executed ur code and found that on pressing enter ur function
mykeydown() gets called twice.Instead of submitting on enter try to submit the
page on any other key it will get printed once.
replace the if block in mykeydown() to the following
if (whichkey==32) //32 is for spacebar
{
alert("inside submit1");
document.thisform.action="cal.jsp";
document.thisform.submit();
}
