Hi, all...
I've put together a page that uses ajax to add, update, preview, and delete
virtual tours for real estate properties using CF and Ajax (jQuery) and a CFC.
Where I need some guidance is the part for the update.
I've got the actual update working fine, but I was wondering how I should
approach getting the new value for the virtual tour field back in the
field on the page itself.
Typically, if I were doing this only in CF, after updating the info
in the db with a query, I'd re-query the db, get the new info and
insert that into the field or leave the field empty based on the query results:
<cfif len(trim(updateStruct.tour_url))>
<input name="tour_url" value="#updateStruct.tour_url#">
<cfelse>
<input name="tour_url" value="">
</cfif>
Currently, I essentially did the same thing in the cfc that processes the
ajax request, by updating the data, then running another query to retrieve
the new data and send that back as part of a struct.
However, I currently have just the one input field for updating the tour_url.
(Is there a question in here? :o)
Should I be focusing on an ajax solution to updating the value in the update
field without using alternative inputs for different values or should I just
have something like the code above to give me an alternate
field that will show if an update value is present? e.g....
<cfif len(trim(initial_page_query.tour_url))>
<input name="tour_url" value="#initial_page_query.tour_url#">
<cfelseif len(trim(updateStruct.tour_url))>
<input name="tour_url" value="#updateStruct.tour_url#">
<cfelseif isdefined("initial_page_query.tour_url") and not
len(trim("initial_page_query.tour_url"))>
<input name="tour_url" value="">
<cfelseif isdefined("updateStruct.tour_url") and not
len(trim("updateStruct.tour_url"))>
<input name="tour_url" value="">
</cfif>
Surely there's a more efficient way of using Ajax to determine the value
that should go in the update field...or do I have to have all these alternative
inputs? (You can see my confusion about how this part with Ajax and CF should
work)
Thanks for any feedback!
