( #3333=superdoc: print w/replies, xml ) Need Help??
When a form is sent I need some Java Script code that will prohibit the form from being sent unless all the fields are non-empty and the fields that hold URLs either hold valid URLs or hold a partial URL with no protocol mentioned. Minimally I mean strings whose first non-blank characters are http:// or ftp:// where case is not an issue. This means that Iwould consider both HttP://www1.gmu.edu and http://www1.gmu.edu as valid. I also would allow for no mention of the protocol as in www1.gmu.edu/~howard/cpsc/495/index.html. Also, some Java Script that will place http:// in a field if someone types a partial URL with no protocol. So if someone were to type www1.gmu.edu in one of the form items that is meant to hold a URL, then it is replaced with http://www1.gmu,edu when the cursor is moved from the form element.

    marto wonders what fresh hell the firefox update has brought, apart from maxing out CPUs
    1nickt was looking into Firefox Extended Support releases yesterday. You don't have to go with the updates!
    [erix]: wonderfully red sun here
    [LanX]: FF has become a source of instability :(
    [1nickt]: erix not so wonderful for the lungs :-(
    [erix]: the stuff is pretty high up as I understand it; I have not felt any effect on lungs/breathing
