Gets a list, without its first element.
A copy of list, without the first element. If list has one element, returns an empty list.

Parameter |
Description |
|---|---|
| list |
A list or a variable that contains one. |
| delimiters |
A string or a variable that contains one. Character(s) that separate list elements. The default value is comma. If this parameter contains more than one character, ColdFusion processes each occurrence of each character as a delimiter. |
If the list begins with one or more empty entries, this function drops them, as well as the first element.
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.
<h3>ListFirst, ListLast, and ListRest Example</h3>
<!--- Find a list of users who wrote messages --->
<cfquery name = "GetMessageUser" datasource = "cfdocexamples">
SELECT Username, Subject, Posted
FROMMessages
</cfquery>
<cfset temp = ValueList(GetMessageUser.Username)>
<p>Before editing the list, it is:
<cfoutput>#ValueList(GetMessageUser.Username)#</cfoutput>.
<p>(Users who posted more than once are listed more than once.)
<p>The first user in the list is:
<cfoutput>#ListFirst(temp)# </cfoutput>
<p>The rest of the list is: <cfoutput>#ListRest(temp)#</cfoutput>.
<p>(Users who posted more than once are listed more than once.)
<p>The last user in the list is: <cfoutput>#ListLast(temp)#</cfoutput>
