  27. Last time: Javascript (forms and functions) Fix up some more code together (if time): http://www.clsp.jhu.edu/~anni/cs103/test2_before.html http://www.clsp.jhu.edu/~anni/cs103/test2_after.html

  29. Homework • Make sure you have a working javascript-based survey on your website: • You should have functions like mailto and displaymsg (don’t rely on the html action tag that does this automatically and not so well) • Don’t worry about radio buttons and checkboxes, they’re harder • Include just textboxes and/or select lists • We’ll learn how to do this in a much easier way with Google Docs later • Go to https://studio.tellme.com/ and sign up for a free account. Play around if you have time, but at least have an account ready to program by next Tuesday
