Re: Find structure in array

Hi,

Your sample code doesn't produce a meaningful array, but I can see
what you're trying to do.

The simplest way would be to cfloop over the array looking at each
name element, e.g:

<cfloop from="1" to="#arrayLen(aBooks)#" index="iBook">
<cfif aBooks[iBook].name EQ "DEF">
<cfset bookDEF = iBook />
</cfif>
</cfloop>

Or you could use one of CF's built in functions, look at structFind()
or structFindValue() as I believe these will work on arrays as well as
structs.

Deciding which to use may depend on performance, so I'd test both
techniques if the array is large.
