Call Javascript function from URL address bar

Question

Is it possible to call a javascript function from the URL  I am basically trying to leverage JS methods in a page I don t have access to the source   Something like  http   www example com mypage aspx javascript printHelloWorld    I know if you put javascript alert  Hello World    into the address bar it will work   I suspect the answer to this is no but  just wondered if there was a way to do it
