This function calls a given closure/function with every element in a given string list and returns true, if one of the closure calls returns true.

listSome(list, closure [, delimiter] [, includeEmptyFields] [, multiCharacterDelimiter] [, parallel] [, maxThreads]) → returns boolean

Member Function Syntax

list.listSome(closure [, delimiter] [, includeEmptyFields] [, multiCharacterDelimiter] [, parallel] [, maxThreads])

This function requires Lucee. Not supported on Adobe ColdFusion, etc.

Argument Reference

list string
Required

string list to iterate

Alias: string

closure function
Required

function/closure that implements the following constructor [function(any value, numeric index,string list, string delimiter):boolean].

Alias: function, callback, udf

Callback parameters:

value* any : current value from the list
index* numeric : position in the list
list* string : string list to iterate
delimiter* string : delimiter used to separate the string list

delimiter string

delimiter used to separate the string list

includeEmptyFields boolean
Default: `false`

include empty fields or not

multiCharacterDelimiter boolean
Default: `true`
