A Few Short Notes

Loading Other Documents

Often, what we want to do after time has expired is to switch to another page (at least that's what we're going to do in our experiment). To do that, we assign a new url to the location object, as in location="results.html" or location="http://www.math.grin.edu/".

If I've stored someone's NT user id in userid, I can switch to their home document with

location="http://www.grinnell.edu/individuals/" + userid + "/"

You can try a really annoying example.

Presentations

Rather than presenting our ``works in progress'' at the end of class, we decided to present them at the beginning of today's class, so let's see what we've been up to. (I've been preparing my other classes, but hopefully you folks have been doing some cool things.)

History

• Updated April 12, 1999. Mostly reformatting. Some changes to accomodate changes to Grinnell's use of pages.
