Parameters
Parameter
list
position
delimiters
Usage
To use this and other functions with the default delimiter (comma), you can code as follows:
<cfset temp2 = ListDeleteAt(temp, "3")>
To specify another delimiter, you code as follows:
<cfset temp2 = ListDeleteAt(temp, "3", ";")>
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.
Example
<!--- First, query to get some values for our list elements--->
<CFQUERY NAME="GetParkInfo" DATASOURCE="cfsnippets">
SELECT PARKNAME,CITY,STATE
FROM Parks
WHERE PARKNAME LIKE 'CHI%'
</CFQUERY>
<CFSET temp = ValueList(GetParkInfo.ParkName)>
<CFSET deleted_element = ListGetAt(temp, "3", ",")>
<cfoutput>
<p>The original list: #temp#
</cfoutput>
<!--- Delete the third element from the list --->
<CFSET temp2 = ListDeleteAt(Temp, "3")>
<cfoutput>
