StringUtils.indexOfIgnoreCase¶

Signature: StringUtils.indexOfIgnoreCase(inputString, searchString, startPosition*)

Returns: Integer index - the first index of the searchString ignoring the case, -1 if no match or null inputString

Finds the first index of searchString within the inputString, handling null ignoring the case. A null inputString will return -1. A negative startPosition is treated as zero. An empty ("") searchString always matches. A startPosition greater than the inputString length only matches an empty searchString.

Parameters¶

Type	Name	Description	Default
String	inputString	the String to check, may be null
String	searchString	the String to find, may be null
Integer	startPosition*	(optional) the `startPosition`, negative treated as zero	0

Example¶

var simpleString = "I am trying to find the number that's making me numb!";
var firstIndexOfNUM = StringUtils.indexOfIgnoreCase(simpleString, "NUM");       // 24
var indexOfNUMAfter40 = StringUtils.indexOfIgnoreCase(simpleString, "nUm", 40); // 48
