In firebug you can select an element in the HTML view. Back in the firebug console, your selected node is available as $1 So, $1.tagName shows you the element name, etc. If you've got dojo on your page you can use anything dojo has provided in the console, and if you're using dijit, you also have that stuff too. So, in the HTML view clickhttp://sam-i-am.com/work/2008/03/dijitbynode-and-firebug-fun.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-7097869770505043773Sat, 23 Feb 2008 05:03:00 +00002008-02-25T22:08:56.897-06:00I recently had to move off a company laptop I'd been using for a while, and (thanks to the flu) didnt have much time to do it. So, I backed up those directories I knew had any personal projects and data in and crossed-fingers I'd be able to get what I needed out of there when the time came. One of the directories I got housed my subversion respositories (I'd been using the flat-file db option). http://sam-i-am.com/work/2008/02/restoring-svn-repositories-from-disk.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-1394018761950592367Tue, 15 Jan 2008 18:45:00 +00002008-01-15T13:10:59.765-06:00workishA man was asked to do some renovation on a house. He worked steadily at it for several weeks and finally called his client to come take a look around. He said, "I was able to keep a lot of the original flooring. I got a good match for the wood and finish where I had to patch and extend the floor. I'm nearly done. I just need to pick up my offcuts and sweep up." "Oh good" said the client.

It lets you declare a new widget class inline in your html - which can be very useful, especially when you want the widget templateString to be dynamic output from the server.

It can be configured with both include conditions, and exclude conditions. If something passes the include filters, it then checks to see if its explicitly excluded. For example, I want to exclude cgi-bin, but include all other directories and files.

None are as whizzy as the dojox.gfx (vector graphics) clock you might have seen around, or your various dashboard widgets - but this is just dojo core + 6k (uncompressed) of code.http://sam-i-am.com/work/2007/11/simple-clocks-with-dojo-toolkit.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-2655276403368988322Wed, 28 Nov 2007 05:57:00 +00002007-11-28T00:27:32.629-06:00javascriptworkishIt may or may not be news to you that in Javascript you can do: someString.replace( /\w+/g, function(match) { return "blah" } ); Which in this case turns "the original string" into "blah blah blah". Your function is passed the match, and you return whatever you want. That's pretty handy, as you can run the match through transformations, or even use it to lookup or generate some http://sam-i-am.com/work/2007/11/stringreplace-with-substitution-by.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-3362311160525754039Wed, 24 Oct 2007 13:25:00 +00002007-10-24T08:46:10.091-05:00the Ajaxian folks are doing their little summary of the past year or so as pertains to Ajax. One of the "trends" or opportunities they observe is doing layout using javascript. CSS got a panning. Now I understand that CSS layout is complex - no argument there. But doing layout in javascript is hardly new and proven to be a dead-end - at least with current browsers. In Dojo 0.9 the widget and http://sam-i-am.com/work/2007/10/tae-keynote-and-css-layout.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-8203757001964707197Fri, 07 Sep 2007 01:34:00 +00002007-09-06T20:53:24.126-05:00This is a quick proof of concept of a sortable, data-store backed list (using dojo 0.9). The store (a dojo.data.ItemFileReadStore instance) does the sorting. Each list-item has an id, that is mapped to the store item identifier. So when the re-sorted list comes back I just look up the list-item node and appendChild it to move it in the list. The store has 52 items (its a list of states) and http://sam-i-am.com/work/2007/09/sortable-list-with-dojo-09.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-2743040805604954402Sat, 21 Jul 2007 08:12:00 +00002007-07-21T07:56:51.596-05:00javascript airI made a quick trip to Dallas to catch the Adobe AIR bus tour there.

You can easily move your FF profile directory to another local drive/directory e.g. thumb drive, or a backed-up directory. In my case it was to a directory that doesn't have every read/write scanned by anti-virus software.

Unlike most reviews I've seen, this author obviously spent sometime with each of the libraries he includes - enough to get a meaningful impression of the strengths and weaknesses. For me, he's right on the money with Dojo, YUI, Rico, Atlas. I differ a little on GWT, but in truth it sounds like he spent more time with it than I did.

Looks like they just came out of beta and are open to the public. This is sweet, I can't emphasize enough how useful this is already proving. 90% of all code (I reckon) is boiler-plate, but by the time you've tracked down an implementation (and possibly ported it to your language of choice) its easier (say, 75% of the http://sam-i-am.com/work/2006/06/krugle-open-source-code-search-engine.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-114779215173902285Tue, 16 May 2006 15:00:00 +00002006-05-16T10:21:00.326-05:00First - javascript doesn't actually have "namespaces". But the idea is there - unless functions, objects and variables are designated otherwise, they exist in the global scope - properties of the window object. In a portal - where portlets might want to include script libraries to facilitate interaction within the portlet - there's a risk of conflicts with objects using the same name being http://sam-i-am.com/work/2006/05/javascript-conflicts-and-portlet.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-114610347112406250Thu, 27 Apr 2006 01:50:00 +00002006-04-26T23:06:32.876-05:00Andrew Dupont has written a very interesting article on Prototype, and the recent $() extensions that allow things like $(someelement).hide() and so on. This is actually a really nice solution. It's syntactical sugar without actually extending the element itself. Andrew argues that as an object oriented language, its reasonable to want to be able to extend objects like HTMLElement in javascript.http://sam-i-am.com/work/2006/04/playing-nice-with-others-in-javascript.htmlSam-I-Amtag:blogger.com,1999:blog-396730.post-114591042147251111Mon, 24 Apr 2006 19:50:00 +00002006-04-24T15:27:01.530-05:00I've been really impressed with the WCAG 2.0 guidelines.
