loop through implicit array - arrays

Question

I've been stuck on this for awhile now. I'm trying to loop through this array so I can perform some calculations but I cannot figure out how to loop through there values. Any suggestions?
I managed to figure out how to get there collection structures but I want to loop through each structure and grab there values as well and thats what I'm stuck on.
Also, I want to refrain from using cfscript if possible as I'm still in the learning stages of learning coldfusion.
Here is my code:
<cfset houseStuff = {
Bedroom = [
'Luxury Duvet Set with Alternative Down Comforter',
'Accent Coverlet & Shams',

],

<cfloop collection="#houseStuff#" item="key">
<cfdump var="#key#"> <br>
<!--- <p style="color:##fff;">#key#:</p> <br /> --->
</cfloop>

Answer 1

Nevermind, I finally figured it out. I had to loop through the collection first. Once I do that create another loop inside it to loop over it's structured values.
<cfloop collection="houseStuff" item="key">
<!---<cfdump var="#houseStuff[key]"> --->
<cfloop from="1" to="#arrayLen(houseStuff[key])#" index="j">
#j#
</cfloop>
</cfloop>

I know you said you'd prefer tags instead of script, but if you are in the learning stages of ColdFusion, I'd still recommend learning how to properly use cfscript. In addition to making your CF a little bit cleaner, it will also make your life a lot easier, especially for things like looping.
Outputting all elements becomes:
<cfscript>
for ( i in houseStuff ) { // loop over the outer Structure
writeOutput(i & ":<br>") ;
for ( j in houseStuff[i] ) { // loop over each inner Array key
writeOutput(j & "<br>") ;
}
writeOutput("<br>");
}
</cfscript>

... which, in this context, does get into the philosophical discussion of whether to write output code in tags or script and goes slightly beyond the scope of this question. But I've always been a proponent of learning best-practices at the same time as the basics. Personally, I do tend to follow the tags-for-output view, but for basic looping, the script version is a bit cleaner to me. I'd learn both.
