Mark Ferree - Open Source Web Development

I just got bit by a strange bug that I haven't encountered before and wanted to share the 5 minute solution with everyone so they don't spend the hour I did trying to install Visual Web Developer Lite in a virtual machine to debug IE's Javascript wackiness.

Firefox could care less if you write your code like this:

      address: {
        required: true,
        minlength: 2,
      },
      city: {
        required: true,
        minlength: 2,
      },
      state: {
        required: true,
      },

But apparently IE blindly chokes unless you write it like this:

      address: {
        required: true,
        minlength: 2
      },
      city: {
        required: true,
        minlength: 2
      },
      state: {
        required: true
      },

Notice all the trailing commas removed, even from one line items. Not sure who is implementing the spec correctly here, but sure makes for a thorny problem when the best tool for JS debugging is Firebug in Firefox and therefore most initial development is done in Firefox.
