A commenter asked me how to extend a previous jQuery post to perform the database save via ColdFusion.  It is REALLY easy (and please keep in mind this is meant to be a SIMPLE example, not production code).  From the jQuery side my example only required the following code to ship the data off to ColdFusion:

function fSave(){
you=$("#you").val();
// Try to save
$.get("adduser.cfm?"+"you="+you , function(data){
// Result
alert(data);
window.location=location.href;
});
}

The adduser.cfm page then validates and inserts the data and returns a success or failure message.

This example starts with a form that has no action and a disabled submit button.  When jQuery’s .ready() fires though it enables the submit button and attaches the appropriate action.

Please note the example file is in ColdFusion so your mileage may vary slightly for your own use.
