String.toUpperCase() Method

generate an uppercase version of a string

Flash 5

string.toUpperCase()

Returns

The uppercase (a.k.a. ALL CAPS) equivalent of string as a new string. Characters without

an uppercase equivalent are left unchanged.

Description

The toUpperCase() method creates a new, uppercase version of string; it can be used for

formatting or for facilitating case-insensitive character comparisons.

Usage

Note that toUpperCase() does not modify string; it returns a completely new string.

Example

"listen to me".toUpperCase(); // Yields the string "LISTEN TO ME"

var msg1 = "Your Final Score: 234";

var msg2 = msg1.toUpperCase(); // Set msg2 to "YOUR FINAL SCORE: 234"
