Try this (just wrote it). It uses the removeAll method of the array
object and is very little code:
<cfscript>
function ListContainsAny(list1, list2){
var aOne = ListToArray(arguments.list1);
var originalCount = ArrayLen(aOne);
aOne.removeAll(ListToArray(arguments.list2));
return ArrayLen(aOne) NEQ originalCount;
}
</cfscript>
For info on removeAll and others, check out this blog post:
