where do i find ? url equivalent ?

i am lookking for url equivalent of ? and &
something like %40

do you know it ?

thank you

for &, use &

for %, I think you can just use the percent sign. Why can't you?

What you're looking for are called escape or url encoded characters; you can find them like this:

alert(escape("?"));

i finaly found it

%26
%3f


thank you
