Deletes an element from a list.

A copy of the list, without the specified element.

List functions

ListDeleteAt(list, position [, delimiters ])

ListGetAt, ListSetAt, ListLen; "Lists" in Chapter 3, "Using ColdFusion Variables," in ColdFusion MX Developer's Guide

To use this and other functions with the default delimiter (comma), you can code as follows:

<cfset temp2 = ListDeleteAt(temp, "3")>

To specify another delimiter, you code as follows:

<cfset temp2 = ListDeleteAt(temp, "3", ";")>

ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.

<!--- First, query to get some values for our list elements--->
<CFQUERY NAME="GetParkInfo" DATASOURCE="cfdocexamples">
   SELECT    PARKNAME,CITY,STATE
   FROM Parks
   WHERE    PARKNAME LIKE 'CHI%'
</CFQUERY>
<CFSET temp = ValueList(GetParkInfo.ParkName)>
<CFSET deleted_element = ListGetAt(temp, "3", ",")>
<cfoutput>
<p>The original list: #temp#
</cfoutput>
<!--- Delete the third element from the list --->
<CFSET temp2 = ListDeleteAt(Temp, "3")>
<cfoutput>
<p>The changed list: #temp2#
<p><I>This list element:<br>#deleted_element#<br> is no longer present 
at position three of the list.</I> </cfoutput>
