How do I find a value in a list?
ColdFusion provides four functions that can help you find a value in a list. The first two are related: listFind() and listFindNoCase(). Both functions will search a list for a value. The first is case sensitive while the second will ignore case.
<cfif listFindNoCase(list, "jacob")>
Jacob is in the list.
</cfif>
The above code snippet will find a match on the word "jacob" even though the case does not match.
The next two related functions are listContains() and listContainsNoCase(). These functions allow for partial matches. So for example:
<cfif listContainsNoCase(list, "Ray")>
There is a Ray in the list.
</cfif>
This code snippet will display a result since "Ray" partially matches "Raymond" in the list. In general you will probably never use listContains() since you almost always want to match an entire list item, not a partial one.
