Exploring ColdFusion Component Runtime Class Properties And Serialization
Posted: March 18, 2010 at 10:34 AM by Ben Nadel
Yesterday, I came across an interesting post by John Whish on getting an entity memento in ColdFusion . As suggested by Sam Farmer , John was using SerializeJSON() and DeserializeJSON() to serialize a ColdFusion component into a JSON string and then reserializing it back into a plain old ColdFusion struct. Typically, serialization wouldn't seem ... read more »

Ask Ben: Blocking WSDL Access In A ColdFusion Application
Posted: March 17, 2010 at 8:56 AM by Ben Nadel
Is there any way to hide the WSDL file generated from a CFC from being viewed on a browser? Evidently .NET allows you to modify the web.config to make this happen; was looking for an equivalent in CF. Thanks much. First off, I have to say that I have no idea why you would want to do this, and I have to say I'm very curious. Perhaps you are trying... read more »

Managing ColdFusion Sessions In A ColdFusion Builder Extension
Posted: March 16, 2010 at 10:33 AM by Ben Nadel
There's been a lot of confusion in my mind as to how exactly ColdFusion session management works in a ColdFusion Builder Extension; sometimes it appears to work and sometimes it doesn't. I've been told by some people that I should rely on the Application scope for persistence. But, at the same time, I've seen with my own eyes that it does work occ... read more »

Your jQuery Selector Context Can Be A jQuery Object
Posted: March 15, 2010 at 9:04 AM by Ben Nadel
This is just a quick post to clear up any confusion over what kind of objects can be used as a context when performing a jQuery selector execution. Sometimes, when reviewing jQuery code, I see people make data type conversions in their context usage: $( "div", myStuff[ 0 ] ) Here, you can see that the programmer is converting their "myStuff"... read more »

FLEX On jQuery: Extending The jQuery Event Object
Posted: March 14, 2010 at 12:08 PM by Ben Nadel
Last week in my FLEX On jQuery series with Joe Rinehart , I explored the idea of creating non-coupled UI elements that communicate indirectly through the use of event listeners and modifiable event behaviors . In that experiment, I used the core jQuery Event object with custom event types to model custom events; but, I get the feeling from sever... read more »

FLEX On jQuery: Decouple Components With Event Listeners
Posted: March 12, 2010 at 9:26 AM by Ben Nadel
In my continuing effort to explore Adobe FLEX as a means to find applicable jQuery / Javascript "best practices", I had a short exchange with Joe Rinehart the other day on FaceBook. It was a very brief conversation, so I didn't have much to go on; but basically, it came down to keeping components loosely coupled through the means of some interme... read more »

Using Base64 Canvas Data In jQuery To Create ColdFusion Images
Posted: March 10, 2010 at 9:49 AM by Ben Nadel
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 (u... read more »

Translating Global jQuery Event Coordinates To A Local Context
Posted: March 9, 2010 at 9:31 AM by Ben Nadel
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 matt... read more »

The Boondock Saints: Back In The Theaters March 11th
Posted: March 8, 2010 at 10:11 AM by Ben Nadel
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 R... read more »

jQuery Mouse Events: PageX/Y vs. ClientX/Y
Posted: March 8, 2010 at 9:19 AM by Ben Nadel
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 ... read more »

URL Rewriting And ColdFusion's WriteToBrowser Image Functionality (CFFileServlet)
Posted: March 5, 2010 at 9:38 AM by Ben Nadel
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. Specifically, I was using the CFImage tag's "WriteToBrowser" action to create a temporary PNG file to be served up by ColdFusion's CFFileServlet. This action creates a image file with the given t... read more »

Drawing On The iPhone Canvas With jQuery And ColdFusion
Posted: March 5, 2010 at 8:44 AM by Ben Nadel
The HTML Canvas element is something that I've known about for a long time but never actually looked at until yesterday. The Canvas element is just what it sounds like - a surface on which we can programmatically render graphics and shapes. After seeing some really cool canvas-based demos floating around on Twitter, I decided that it was finally t... read more »

FLEX On jQuery: Turning HTML Links Into Standard UI Elements
Posted: March 3, 2010 at 8:39 PM by Ben Nadel
In my first "FLEX on jQuery" blog post yesterday , I talked with Javier Julio about some of the similarities and differences between FLEX applications and rich jQuery applications. As we talked, one of the patterns that I began to see was the significant difference in the inherent power of "link" elements in the two different technologies. I sa... read more »

FLEX On jQuery: The Relative Power Of Link Elements
Posted: March 3, 2010 at 10:17 AM by Ben Nadel
Mentally, I am still very much in the web application world of the traditional client-server request-response life cycle. I think in terms of page requests and view rendering; and, as my ability to code complex jQuery applications increases, I fear that my understanding of client-side architecture "best practices" is not keeping up. After a lot of... read more »

Experimenting With jQuery's Queue() And Dequeue() Methods
Posted: March 2, 2010 at 9:10 AM by Ben Nadel
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 mech... read more »
