Small world, Andy. Just last week my
wife tried to get me to build a tool to generate shopping lists from her
monthly menu. (I said I didn’t have time…)<o:p></o:p>
<o:p> </o:p>
Thanks again for the information.<o:p></o:p>

Most of the time, I'm using the CFC to do
all of the formatting, then I return a simple string containing all of the HTML
that needs to be applied to the page. For example. take a look at <a
href="http://www.co-opcookbook.com">www.co-opcookbook.com</a>. That's where I
pulled that sample code from.<o:p></o:p>
 <o:p></o:p>
When you perform a search, it runs the CFC
using the provided keyword. The CFC queries the database, loops over the
results, adding in the appropriate HTML, then returns that long string of
text to the calling JS function.<o:p></o:p>
 <o:p></o:p>
That might not be the most efficient way
of doing things (if it's not PLEASE someone speak up, I want to get better),
but it's the way that makes sense to me.<o:p></o:p>

Andy, this is also good to know. I
guess I’ll figure this out eventually, but what doesn’t yet make
sense is how to handle complex objects (queries, structs) being returned from
the CFC. Do you just handle the formatting in your CFC so you can pass
back (or simply output, I guess) a string and use
$(“#element”).html() to replace the content, or do you handle formatting
on the client side? (By “you” I mean Andy specifically but
the rest of you generally as well…)<o:p></o:p>
<o:p> </o:p>
I’m learning a lot…<o:p></o:p>

Just so you know, you CAN use jQuery to
hit the CFC directly. Here's a sample of code I'm using:<o:p></o:p>
 <o:p></o:p>
js code:<o:p></o:p>
function addRecipe(id) {
$.get("includes/q.cfc?method=addRecipe&id=" +
id,function(result){
 eval( 'var ' + result );
 $('#shoppingList').html(r.content);
});
};<o:p></o:p>
 <o:p></o:p>
CFC:<o:p></o:p>
<cffunction name="addRecipe"
access="remote" returntype="void" hint="Adds a recipe
to your shopping list">

<cfargument name="id" required="Yes"
type="numeric">
<cfset myStruct = structNew()>
<cfif NOT ListFind(SESSION.grocerylist,id)>
 <cfset SESSION.grocerylist =
ListAppend(SESSION.grocerylist,id)>
</cfif>
<cfset myStruct["content"] = Replace(getShoppingList(),"#chr(13)#","","ALL")>
<cfwddx action="CFML2JS" input="#myStruct#"
toplevelvariable="r">
</cffunction><o:p></o:p>
 <o:p></o:p>
 <o:p></o:p>
 <o:p></o:p>
<o:p> </o:p>
<pre><o:p> </o:p></pre></div>
</body>
</html>
