Parameters
Parameter |
Description |
|---|---|
includeEmptyFields |
Optional. Set to yes to include empty values. |
list |
A list or a variable that contains a list. |
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; you cannot specify a multicharacter delimiter. |
Usage
If you use list functions on strings that separated by a delimiter character and a space, a returned list element might contain a leading space; use the trim function to remove leading and trailing spaces from a returned element. For example, consider this list:
<cfset myList = "one hundred, two hundred, three hundred">
To get a value from this list, use the trim function to remove the space before the returned value:
<cfset MyValue = #trim(ListLast(myList)#>
With this usage, the MyValue variable gets the value "three hundred", not " three hundred", and spaces within a list element are preserved.ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.
Example
<cfscript>
myList="Tokyo,Bangkok,Jakarta,Manila,Bangalore,Shanghai";
WriteOutput(ListLast(myList)); //Returns the last element in the list, Shanghai
</cfscript>
Output
Shanghai
