js > cf

[Silvestro]

Hello,

I need to get some data from a js file, and process it through cf/db tag.

What is the best way? I think it should be asynchronous, but I have still to get the principles of js to cf communication.

Thanks!

The js has to make an http request to a cf page.  This page might give you some ideas.  http://www.google.ca/#hl=en&source=hp&biw=1280&bih=885&q=javascript+httprequest&aq=0&aqi=g10&aql=&oq=javascript+htt&fp=4f06745222af36bd

In order to do an http request, you an use many of the great JS options incorporated into CF like :

ColdFusion.Ajax.submitForm

http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=JavaScriptFcns_03.html

for example you can create a form on your page that will be set with data via JS and posted to a CF page.

Also you can use the ColdFusion.navigate

http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=JavaScriptFcns_24.html

in order to navigate to a certine page with info, letting that page handle the CF.

If you need more info, or examples, let me know
