Returns
The lowercase equivalent of string
as a
new string. Characters without a lowercase equivalent are left
unchanged.
Description
The toLowerCase( )
method creates a new,
lowercase version of string
; it can be
used for formatting or to facilitate case-insensitive character
comparisons. The toLowerCase( )
method converts
only characters in the range A-Z (it does not convert characters with
diacritical marks such as accents and umlauts).
Usage
Note that toLowerCase( )
does not modify
string
; it returns a completely new
string.
Example
// Set msg to "this sentence has mixed caps!" msg = "ThiS SenTencE Has MixED CaPs!".toLowerCase( ); // Perform a case-insensitive comparison of two strings function caseInsensitiveCompare (stringA, stringB) { return (stringA.toLowerCase() == stringB.toLowerCase( )); } trace(caseInsensitiveCompare("Colin", "colin")); // Displays: true
