neillzero on #rubyonrails pointed us at this Greasemonkey script (blog post about it) which is even more appropriate for debugging Ajax stuff than the other techniques I’ve mentioned here. In addition to showing you the requests, it even lets you modify requests. As the author says: Each individual XMLHttpRequest invocation will get listed there, with […]
Daryl of Two Ells has come up with another way to solve that blasted “Packets out of order” error, without installing a new gem. Just a refresher, to anyone who’s finding me via Google and doesn’t know what this error means: It refers to the changed MySQL password hashing in version 4.1 and greater. You […]
I’m prototyping an internal application for my company, and I’m using Rails to do it (yay!). It’ll probably turn into a Javascript-only application, with some hooks to the server, later on. In the mean time, I get to do such fun stuff as this: <script type=”text/javascript”> Droppables.add(‘conditional_<%= @id %>’, {hoverclass:’hover’, onDrop:function(element){ new Ajax.Updater(‘conditional_<%= @id %>’, […]
Need to see Javascript generated by an Ajax helper in an Ajax response? Well, you won’t be able to see it by viewing source because, since it’s an Ajax response rendered by Javascript, it’s not technically part of the source at all. But you can still see the Javascript—and what may be going wrong—like thus: […]
You’ve read the ONLamp tutorial, but you lust for more. So you want to autocomplete, do ya? Do ya?? You’ve come to the right place.
I’d like to spend a little time today talking about the power that tools, techniques, and languages have on our brains. There seems to be fairly wide acceptance for the theory that language and literacy affect the structure and function of our brains. I think the lessons learned there can be applied to programming languages, […]
Apparently it’s not crack that Ruby brings to the table. Witness: def date=(val) [:year, :month, :day].each do |meth| raise ArgumentError unless val.responds_to?(meth) end @date = val end Let’s see that one line again: [:year, :month, :day].each do |meth| Yes, you read it here first! Ruby, promoting meth use. The first one’s free! From this RubyTalk […]
Being a designer is a tough gig. Oh, I know, poor me, right? But wait. Let me explain. As a designer, it’s easy to make a fool out of yourself. Even the most self-deprecating designer has this problem occasionally, and so do I. We want to love all our designs. They are our children, even […]
Check out Qooxdo (as in “cooks do”), an open-source set of Ajax “widgets.” None of em show up in Safari 2, so I can’t try them—but they have a page of screenshots.The site is very attractive, and the name creative, so I was hoping for a really whizbang product. Aaand… they all look like Windows. […]
