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.**bug 24114 tlane |
|
|
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.
