Parameters

Parameter | Description
list | A list or a variable that contains a list.
delimiters | A string or a variable that contains one. Character(s) that separate list elements.
| Default: comma.
| If this parameter contains more than one character, ColdFusion processes each
| occurrence of each character as a delimiter; you cannot specify a multicharacter
| delimiter.

Usage

If you use list functions on strings that separated by a delimiter character and a space, a returned list element might contain a leading space; use the trim function to remove leading and trailing spaces from a returned element. For example, consider this list:

    <cfset myList = "one hundred, two hundred, three hundred">

To get a value from this list, use the trim function to remove the space before the returned value:

    <cfset MyValue = #trim(ListLast(myList)#>

With this usage, the MyValue variable gets the value "three hundred", not " three hundred", and spaces within a list element are preserved.
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.

Example

    <h3>ListFirst, ListLast, and ListRest Example</h3>
    <!--- Find a list of users who wrote messages --->
    <cfquery name = "GetMessageUser" datasource = "cfsnippets">
       SELECT Username, Subject, Posted
       FROM  Messages
    </cfquery>
    <cfset temp = ValueList(GetMessageUser.Username)>
    <p>Before editing the list, it is:&nbsp;
    <cfoutput>#ValueList(GetMessageUser.Username)#</cfoutput>.
    <p>(Users who posted more than once are listed more than once.)
    <!--- Show the first user in the list --->
    <p>The first user in the list is: <cfoutput>#ListFirst(temp)#</cfoutput>
    <p>The rest of the list is:&nbsp;<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>
