It will work because if there is a number, parseInt will return it, thus
it's a true value.
the only time this will not work as expected is if the form element contains
a "0"
parseInt will return it, but 0 in the if will end up as a false and will be
rejected.

here's a dirty hack around it.  (untested)

if (parseInt(temp,2)+"" == "NaN")
    alert("Not a valid Number")
else
    alert("A valid Number")
