ColdFusion Ajax Related Selects
Hello experts
I'm trying to use the tutorial :ColdFusion Ajax Tutorial 2: Related Selects from :http://www.forta.com/blog/index.cfm/2007/5/31/ColdFusion-Ajax-Tutorial-2-Related-Selects.
The problem i have is to set a value for the child select box when the parent id is "".(the default value for -select all-.i did put this in the db table because i could not use it in the cfselect.If that is possible please help me with this too).
On page load must the parent display be -all- and the child -all- too.
Here is my code.

Hi srikanthmadishetti:
I did just see your post.I'm trying to test it but it does crash .
I did change the db because i thought that erikTsomik did mean to do this.

<cfreturn result>
</cffunction>
you can say in the query that <cfif name neq 0>
then do sigle item
</cfif>
then do sigle item
</cfif>
btw, you do not need to convert your query to an array for a cfselect - it works just fine with a query.

azadi i'm trying to use another way for related selects instead of the jsmx library i did use because i do need another way for simultaneous ajax requests.(i had the problem here:https://www.experts-exchange.com/questions/24478424/JSMX-and-number-of-simultaneous-ajax-requests.html)

I did change the value to 0 and put anothet row in the child table - for Auto_id 0 ,a value All for Modell_DE and "" for Modell_ID and it seems that it is working.
The new query is the following .Can it be more simplier?
