Escaping Form Values - Understanding The ColdFusion htmlEditFormat() Life Cycle
Posted: September 3, 2010 at 3:53 PM by Ben Nadel
When users can interact with your website by submitting content, it opens your site up to potential harm. In the worst case scenario, this might provide malicious hackers with a way to execute Cross-Site Scripting (XSS) attacks; in the best "bad" case scenario, it might simply mess up your site's layout and lead to a poor user experience. All of t... read more »

Scope Behavior When Using CFThread Inside Of ColdFusion Components
Posted: September 2, 2010 at 11:10 AM by Ben Nadel
The other day, I was using CFThread to call a ColdFusion component method asynchronously. Typically, when I use CFThread, I define my CFThread tags in the controller. In this case, however, I was making the asynchronous call from within the context of the component itself. This works very well. But, but there are some minor variances in scope-beha... read more »

Creating Base64-Encoded Data URLs For Images In ColdFusion
Posted: September 1, 2010 at 10:31 AM by Ben Nadel
Typically, when we want to include an image in a web page, we use an IMG tag with a SRC value that points to a file located on the server (ex. my_image.jpg). Modern browsers, however, allow us to embed images directly in the page markup as Base64-encoded "data urls." For caching and performance reasons, you generally wouldn't want to use data urls... read more »

Using jQuery's Proxy() Method In Event Binding And Unbinding
Posted: August 31, 2010 at 10:56 AM by Ben Nadel
Yesterday, I explored the use of jQuery's native event management in the creation of object-oriented publication and subscription (pub/sub) functionality . In order to do this, I had to make use of jQuery's new proxy() method that allows function callbacks to be executed in the context of an object instance rather than a DOM node (which is typica... read more »

Powering Publish And Subscribe Functionality With Native jQuery Event Management
Posted: August 30, 2010 at 9:50 AM by Ben Nadel
Let's face it - jQuery's native event management is straight-up awesome! Between multi-type binding, name-spaced events, proxied callbacks, and function-specific unbinding, there's not much that it can't do (and do well, for that matter). Without a doubt, it's better than any event management that I could write. As such, I wondered if I could use ... read more »

Reflections On My Client-Side MVC View-Rendering Hackathon
Posted: August 29, 2010 at 1:15 PM by Ben Nadel
Yesterday, I spent about 10 straight hours exploring client-side MVC View-rendering in my first (of many) solo hackathons . I came up with a UI design, broke it out into HTML and CSS, and then coded a thick-client application on top of it; and, I did all of this under the pretense that the project would end up being a complete failure. As I expla... read more »

Using jQuery To Bind And Trigger Event Handlers On Detached DOM Nodes
Posted: August 27, 2010 at 5:00 PM by Ben Nadel
Often times, we use jQuery to bind event handlers to DOM nodes that are children of the current document tree. When we do this, jQuery stores the event handlers in the given node's "events" collection . These bindings remain in place until they are explicitly unbound or until the DOM nodes are removed from the document ( NOTE : Using .detac... read more »

Saturday Hackathon: Client-Side MVC - The Wrong Way
Posted: August 27, 2010 at 10:23 AM by Ben Nadel
Over the past week, I've heard a number of people talk about various hackathons, hack days, pitch days, and general all-night coding adventures. I've never attended one of these events and I have to say, hearing about them makes me more than a little bit jealous. I understand that a majority of the fun that people get out of these things is due to... read more »

jQuery Selectors - The Firebug Plugin Inserts A Hidden DIV Element
Posted: August 27, 2010 at 9:04 AM by Ben Nadel
Last night, I was testing out someone's jQuery queue() and dequeue() code and I had a bug that was just driving me crazy; no matter how simple I made my test, my queued callbacks kept firing twice. To give you some insight into how simple my code was, take a look at this demo: <!DOCTYPE html> <html> <head> <title>Hi... read more »

AJAX Requests Get And Set Cookies Like Any Other HTTP Request
Posted: August 25, 2010 at 11:03 AM by Ben Nadel
Sometimes, people ask me how to handle session management within an application that makes AJAX requests. A question like this can mean many different things; but often times, after a little discussion, I discover that this question is based on a fundamental misunderstanding of what an AJAX request actually is. Because we are so used to the reques... read more »

Overriding Internal ColdFusion Component Variables With Method Arguments
Posted: August 24, 2010 at 10:30 AM by Ben Nadel
One of the many cool things that Elliott Sprehn talked about in his CFUNITED 2010 presentation was the fact that ColdFusion component variables could be overridden using method arguments. After I saw this, I tried to experiment with this concept on my own. At first, I could not get it work. Elliott's presentations were all done in ColdFusion 9... read more »

Using Dynamic Keys In ColdFusion 9's Implicit Struct Creation
Posted: August 23, 2010 at 9:54 AM by Ben Nadel
At CFUNITED 2010, I attended Elliott Sprehn 's presentation, " I Bet You Didn't Know You Could Do That With ColdFusion ." In his code samples, I saw something that I had never seen before - he was using quoted-keys in his ColdFusion implicit struct creation. In ColdFusion 8, this definitely causes a parsing error at compile time. But, it looks li... read more »

THIS Is Just A Locally-Scoped Variable Inside Of ColdFusion User Defined Functions
Posted: August 20, 2010 at 10:14 AM by Ben Nadel
Yesterday, when I was coding my this.jarPaths application-specific URLClassLoader proof-of-concept , I stumbled upon a very interesting feature of ColdFusion. To make the proof-of-concept work, I had to take a user defined function (UDF) located within the Application.cfc component and store a reference to it in the global URL scope. However, eve... read more »

Using THIS.jarPaths To Create An Application-Specific URL Class Loader In ColdFusion
Posted: August 19, 2010 at 11:11 AM by Ben Nadel
At this last CFUNITED, Rupesh Kumar gave a talk titled, "Extending Java Applications with ColdFusion." In the Q&A portion of the talk, I asked Rupesh if Adobe had any plans to make application-specific Java class loaders in the same way that Application.cfc can currently define its own mappings and custom tag paths. He said that this was som... read more »

Building A Twitter-Inspired RESTful API Architecture In ColdFusion
Posted: August 18, 2010 at 11:21 AM by Ben Nadel
A while back, I gave a ColdFusion API presentation at Scotch On The Rocks 2010 . While I think the content of the presentation was decent, I don't think that it had any right being a presentation. As someone accurately described it in a review (sorry, I can't remember who it was), the presentation was like attending one of my blog posts. This is ... read more »
