ListAppend

Returns list with value appended behind its last element.

See also ListPrepend, ListInsertAt, and ListSetAt.

Syntax

ListAppend(list, value [, delimiters ])

list

Any list.

value

Number or list being appended.

delimiters

Set of delimiters used in list.

Usage

When appending an element into a list, ColdFusion needs to insert a delimiter. If delimiters contains more than one delimiter, ColdFusion defaults to the first delimiter in the string, or, (comma) if delimiters was omitted.

If you intend to use list functions on strings that are delimited by the conjunction ", " (comma-space), as is common in HTTP header strings such as the COOKIE header, we recommend that you specify delimiters to include both comma and space because ColdFusion Server does not skip white space. For example,

ListAppend(List, "MyCookie", "," & CHR(32))
