ListInsertAt

Inserts an element in a list.

A copy of the list, with value inserted at the specified position.

List functions

ListInsertAt(list, position, value [, delimiters ])

ListDeleteAt, ListAppend, ListPrepend, ListSetAt

Parameter	Description
list	A list or a variable that contains one.
position	A positive integer or a variable that contains one. Position at which to insert element. The first list position is 1.
value	An element or a list of elements.
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.

When inserting an element, ColdFusion inserts a delimiter. If delimiters contains more than one delimiter, ColdFusion uses the first delimiter in the string; if delimiters is omitted, ColdFusion uses a comma.

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

<!--- This example shows ListInsertAt --->
<cfquery name = "GetParkInfo" datasource = "cfsnippets">
SELECT PARKNAME,CITY,STATE
FROM PARKS
WHERE PARKNAME LIKE `DE%'
</cfquery>
<cfset temp = ValueList(GetParkInfo.ParkName)>
<cfset insert_at_this_element = ListGetAt(temp, "3", ",")>
<cfoutput>
<p>The original list: #temp#
</cfoutput>
<cfset temp2 = ListInsertAt(Temp, "3", "my Inserted Value")>
