  Creating Base64-Encoded Data URLs For Images In ColdFusion

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  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 to define your images; however, in some cases, it's tremendously useful to serialize and reference an image without needing an additional HTTP requ ... Read More »

  Using jQuery's Proxy() Method In Event Binding And Unbinding

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  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 typical ... Read More »

  Powering Publish And Subscribe Functionality With Native jQuery Event Management

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  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 the native jQuery event management to power publish and subscribe (pub/sub) functionality within my Javascript applications. ... Read More »

  Reflections On My Client-Side MVC View-Rendering Hackathon

  Yesterday, I spent about 10 straight hours exploring client-side MVC View-rendering in my first (of many) solo hackathons .

  Using jQuery To Bind And Trigger Event Handlers On Detached DOM Nodes

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  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 ... Read More »

  Saturday Hackathon: Client-Side MVC - The Wrong Way

  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 the fact that you have so many people together doing the same thing. But, I'm an impatient man and I believe that the next hackathon in my area is ... Read More »

  AJAX Requests Get And Set Cookies Like Any Other HTTP Request

  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 request-response life cycle, there is something almost magical about an AJAX request that runs in parallel to the page processing; heck, I use them all th ... Read More »

  What If ColdFusion's CFThread Tag Had An Interval Attribute?

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  In Javascript, there are two functions - setTimeout() and setInterval() - that allow you to perform actions in an asynchronous fashion. While setTimeout() executes only once, setInterval() will execute a given function repeatedly at the given interval. On the ColdFusion side, we have CFThread, which allows us to perform asynchronous tasks; but, unlike Javascript, the only way to create repetitive asynchronous behavior in ColdFUsion is to use something like a scheduled task. Scheduled tasks ar ... Read More »

  Last night, I was laying in bed thinking about Jenna Elfman in Can't Hardly Wait (one of the best coming-of-age movies ever), when suddenly, I started thinking about named arguments in ColdFusion.

  ToJava() - A ColdFusion User Defined Function For Complex Java Casting

   » ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com
  ColdFusion is a typeless language; and, when we reside in the ColdFusion world, this is a beautiful feature that none of us really have to care about. But, from time to time, we have to dip down into the strongly-typed world of Java that lies just below the surface. At that point, going from lose ColdFusion data types to strict Java data types can be a bit of a headache. ColdFusion comes with a function - javaCast() - that is supposed to make this transition easier; and, most of the time it d ... Read More »
