Question Java blocking broncode

I know that this isn't really the place to ask, but mabey someone knows: Does anyone know, if it is possible WHIT a JAVASCRIPT to block the broncode so that you can't see it at all (also when you would save the page)? I know that there is a script of it in PHP format (if any one knwos were I can get it, it would be nice) but I haven't found one yet specially fo java, and it has to be java becuase it will be used for a site that don't accept php. So I really would like to know if anyone knows if sutch a script is really there and were I can get it for java (and ofcourse also for PHP, as I asked in this question before). So (verry important) I need it so that when I go to my broncode there will be nothing to view also when you save the page!!! M.B.
