ListFind

Determines the index of the first list element in which a specified value occurs. Case-sensitive.

Index of the first list element that contains value, with matching case. If not found, returns zero. The search is case-sensitive.

List functions

ListFind(list, value [, delimiters ])

ListContains, ListFindNoCase

Parameter Description

list

A list or a variable that contains one

value

A string, a number, or a variable that contains one. Item for which to search. The search is case-sensitive.

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.

ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.

<!--- Uses ListFind and ListFindNoCase to see if a substring exists in a list --->

   <p>Try changing the case in Leary's last name: 
   <br><input type="Text" size="25" name="myString" value="Leary"> 
   <p>Pick a search type: 
      <select name="type">

         <option value="ListFindNoCase">Case-Insensitive 
      </select>
