  Using Base64 Canvas Data In jQuery To Create ColdFusion Images

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  Last week, I explored the HTML Canvas element for the first time. In that exploration, I created a "finger painting" demo for the iPhone that would post drawing commands to the server where the image would be re-created as a PNG in ColdFusion. That was a nice approach because it gave me some flexibility in how the ColdFusion image was created (using anti-aliasing and a t ... Read More »

  Translating Global jQuery Event Coordinates To A Local Context

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  When you use jQuery to capture mouse events (mousedown, mouseup, click, etc.), the jQuery Event object contains the X and Y coordinates of the mouse position at the time the event was triggered. These coordinates, while somewhat different in each browser, have been standardized by jQuery to be available in the pageX and pageY properties . No matter what the target of the event is, these ... Read More »

  The Boondock Saints: Back In The Theaters March 11th

  In honor of its ten-year anniversary, The Boondock Saints (the original) is going to be back in the movie theaters for one night on March 11th (this Thursday) as a Fathom Events screening. I love this movie and I never got the chance to see it on the big screen. The first time I ever saw it, I think I purchased it on a whim for $1.99 in a Virgin Records "DVD Clearance" bin.

  jQuery Mouse Events: PageX/Y vs. ClientX/Y

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  When I first starting playing with jQuery events, a lot of what I learned about the jQuery Event object was through trial and error. While I could be remembering incorrectly, I used to find that the jQuery documentation was good at describing the event handlers, but not so good at describing the event object; as such, while I knew that the jQuery event object was a standardized event object, I was never 100% sure which parts of it I was supposed to be using. ... Read More »

  Yesterday, as I was experimenting with drawing on an HTML canvas element with jQuery , I was using ColdFusion to render temporary images to the browser.

  The HTML Canvas element is something that I've known about for a long time but never actually looked at until yesterday.

  Mentally, I am still very much in the web application world of the traditional client-server request-response life cycle.

  Experimenting With jQuery's Queue() And Dequeue() Methods

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  jQuery comes with a number of built-in animation methods like slideUp() and slideDown(). While these appear to be packaged in their own methods, many of them are powered internally by the animate() method. And while the animate() method handles many of the effects, a string of sequential animations is controlled internally by jQuery's queuing mechanism. This queuing mechanism, while used primarily for the FX ("effects") queue, is also made available as part of the jQuery API. This API allows ... Read More »

  Be Careful When Including Images In jQuery Auto-Suggest

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  Yesterday at work, we ran into a very interesting problem involving a jQuery auto-suggest feature on one of our client sites. We had implemented auto-suggest on this particular site several times before and it had always proved to be very zippy and responsive. This time, however, the "suggest" page requests were taking 5, 6, sometimes 8 seconds to complete; this kind of delay clearly defeats the purpose of auto-suggest.

  I can't remember where it was exactly (maybe Twitter), but the other day, someone asked me a question about replacing a string that was not contained within another string. It was something like, "I want to replace all apostrophes in a string. But, I don't want to do that if they are inside HTML comments."

  For a long time, I have thought about API request failures as falling into just two distinct categories: failure to communicate (ie. the server was down) or bad data (ie. invalid parameters). Failures to communicate with the server were out of my hands; as such, there was nothing I could do with those from a server standpoint. Requests with bad data, on the other hand, were certainly something within my domain of control and, happened to be something that I had strong feelings about. Mu ... Read More »

  A few years ago at CFUNITED, I was talking to Rupesh Kumar about the new CFThread features he built into ColdFusion 8. In the conversation (which may have been a presentation), Rupesh mentioned that the CFThread tag body actually executes as a function call.

  Before I went to the gym today, my lower back was feeling a little bit tired. I had done squats at 275lb on Thursday (2 days ago) and was still feeling it in my quads and lower back. But, my back didn't feel weak, it just felt tired; as such, I thought I would try some deadlifts just to see how my body reacted.

  Traversal vs. Collection Filtering In jQuery

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  When it comes to jQuery selectors, I tend to think in two different modes: collection filtering and traversal filtering. By that, I mean that I see filtering as happening at two different and distinct times in the selection process. With collection filtering, jQuery filters nodes only once it has compiled them into a collection. All filtering done at that point is done in the context of the collection. With transversal filtering, on the other hand, jQuery filters nodes as it gathers them duri ... Read More »

  Every now and then, I have a situation where I have a given set of nodes and I need to get particular ancestors of those nodes. jQuery currently provides three ways of accessing ancestors of a given collection: parent(), parents(), and parentsUntil().

  If you're a web developer, chances are good that you are building your web applications using the jQuery Javascript library. And, if you're doing that, chances are, you're loving it; jQuery's appeal comes from, in no small part, that fact that it provides a tremendous amount of power with a very small, very manageable API. And, while this is obviously a good thing, jQuery's ease of use can quickly allow us to become complacent in our learning. The jQuery development team is ... Read More »

  Making sure that your ColdFusion applications are uniquely named is crucial to proper application performance.

  For the past couple of days, I've been building some very exciting internal tools for the company (specifically for prototyping). While these tools are straightforward at the server level, they're becoming quite complex at the User Interface level. At first, I was doing fine, slowly adding features; but now, the interactions between the various user interface components are becoming a bit too much for me to manage. As such, I thought I'd take some time to "white page" an idea and hopefully ge ... Read More »

  I love databases; but, if I'm writing a small application or proof of concept, often times, I don't want to have to go through the bother of creating a new database and its accompanying Data Source Name (DSN). In cases like this, I'll typically use flat files to persist simple data between application instantiations.
