listInsertAt

Description

Inserts an element in a list.

Syntax

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

Attributes

Attribute	Description	Required	Default
delimiters	A string or a variable that contains one. Characters 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.
includeEmptyValues	Optional. Set to yes to include empty values.
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.

Returns

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

Usage

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.
