LISTDELETEAT |
Description Deletes an element from a list.
Returns A copy of the list, without the specified element.
Category List functions
Function syntax
    ListDeleteAt(list, position [, delimiters ])
See also ListGetAt, ListSetAt, ListLen; "Lists" in Chapter 3, "Using ColdFusion Variables," in ColdFusion MX Developer's Guide
Parameters
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="cfdocexamples">
       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>
    <p>The changed list: #temp2#
    <p><I>This list element:<br>#deleted_element#<br> is no longer present
    at position three of the list.</I> </cfoutput>

LIST |

A list or a variable that contains one.

POSITION |

A positive integer or a variable that contains one. Position at which to delete element. The first list position is 1.

DELIMITERS |

A string or a variable that contains one. Character(s) 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.
