Getting bindable attribute values in JavaScript
Use the
ColdFusion.Ajax.submitForm
a bindable control. This technique is useful for getting values for complex controls such as
more information, see the ColdFusion.Ajax.submitForm function in the CFML Reference.
Managing the client-server interaction
Manage the client-server interaction in several ways:
• Use the
tag to create a client-side JavaScript proxy for a CFC and its functions. You then call the
cfajaxproxy
proxy functions in client JavaScript code to access the server-side CFC functions.
• Use the
cfsprydataset
set to populate Spry dynamic regions. You also use Spry data sets in bind expressions.
• Use the
tag to bind fields of ColdFusion Ajax form controls as parameters to a specific CFC function,
cfajaxproxy
JavaScript function, or HTTP request, and specify JavaScript functions to handle successful or error results. The
function is run each time the event determined by the bind expression occurs.
• Use ColdFusion Ajax-based UI tags, such as
using data binding.

ColdFusion" on page 874. For detailed information on using binding, including how to use binding with ColdFusion
UI tags and the
