|
Parameter |
Description |
list |
A list or a variable that contains one. |
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. |
|
|
Usage
|
If the list begins with one or more empty entries, this function drops them, as well as the first element.
|
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.
