This sounds really usefull. Do you have any examples? Inandjo Taurel wrote: i have also used vm to generate dynamic JS code, to have cascade select boxes.

I was going to do something like that but I was looking for a more general solution that could work the same for any object without much coding. As it seems there's no such method, I'll take yours with your code as a working example. Thanks.

Generating javascript code with velocity
Hi. I've been using turbine for a while and i've been using velocity for generating html and javascript code inside .vm files, but now I'd like to take the javascript code out to its own .js file. That will make my pages smaller, but I can't use the velocity template engine inside .js files. Is there some way to not lose this functionality when working with external js files? How do you deal with this? Thanks. -- Bernardo Arlandis Mañó * http://berarma.webhop.org/ * http://mozilla.webhop.org/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Generating javascript code with velocity
My experience has been to move as much code as possible into .js files that do not require velocity processing as the .js files can be cached by the browser. However, by the nature of using velocity to generate javascript code, isn't it dynamic? I don't think there is an easy answer to your question. Could you create a Javascript screen as we have seen others creating dynamic charts and linking to them in that manner, I would think maybe you can create a Javascript screen and have your code generated there as you call it from within the main .vm you are currently working on. This still doesn't seem to have much benefit other than seperating the location of the code from the screen. Jeff Painter On Fri, 28 May 2004, Bernardo Arlandis Mañó wrote: Hi.
