Ajax Features in ColdFusion 8

I gave a presentation titled "Introductionto Ajax Features in ColdFusion 8" at the Syracuse ColdFusion User Group meeting this week.   In the presentation, I covered the following.

  • The basic layout elements that are used with Ajax
  • Automatic Ajax – Things that ColdFusion 8 handles for you – without needing to program any JavaScript.
  • Almost-Automatic Ajax – Things that require one or two lines of code, but not extensive use of JavaScript.
  • Manual Ajax – These are the most powerful features, but will require some JavaScript coding.
  • Ajax Goodies – A couple smal small features in CF8 with big impact.

There is also a sample application that shows an employee management database interface created using all CF8 Ajax – no page reloads.

NOTE: In order to run the samples on your server, you will need ColdFusion 8.  A couple of the samples, including the full application, require MySQL (or another database).  Run the ajaxpreso.sql file (included) on your MySQL database and set up a CF DSN called 'ajaxpreso'.  The tables aren't very complicated – if you run MS SQL, just look at the .sql file and you'll see how the tables are set up.  You can set those up manually.

  1. Thanks for this! Some of these samples explain things that Adobe left out of all their docs. This is a big help as I learn how to make all this stuff work. Are all the ColdFusion.Layout functions documented somewhere?

  2. Hey,

    Is there any way we can load content inside a div by passing div id and url in javascript.

    I want to know whether its possible to direclty do with cf8 ajax tags with the minmal use of javascript.

    I ahve seen numerous examples in cf8 ajax features but not the logic i have mentioned above.

    Any advice or suggesstion wil really help…


  3. Anhijit,

    You should be able to accomplish this using the ColdFusion.navigate function like this:

    Just call it like this:

    Docs on ColdFusion.navigate are here:

    I think that is “minimal” use of JavaScript. If you want to simplify it even more, you could just call the JavaScript line directly:

  4. Hey thanks a lot…I just printed my own name wrong………..I am getting the error ColdFusion is not defined…
