ActionScript Language Reference

Description

The concat() method creates a string from a series of values. It is equivalent to using the

concatenation operator (

+) with strings but is sometimes preferred for clarity, as the + oper-

ator can also be used to add numbers. For details on concat(), see Chapter 4.

Usage

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

Example

var greeting = "Hello";

excitedGreeting = greeting.concat("!");

trace(greeting); // Displays: "Hello"

trace(excitedGreeting); // Displays: "Hello!"

var x = 4; // Initialize x as an integer

trace(x + 5); // Displays: 9

trace(x.concat(5)); // Fails because x is not a string

trace(String(x).concat(5)); // Displays: "45"

var x = "4"; // Initialize x as a string

trace(x.concat(5)); // Displays: "45"

trace(concat("foo", "fee")); // Fails because concat() must be

// invoked as a method of a string
