The preceding code shows two methods of concatenating strings. The first method uses
the addition (+) operator to join the

concat()
is demonstrated in the following example.
To concatenate two strings with the concat() method:
1.
Create a new Flash document and save it as concat2.fla.
2.
Add the following code to Frame 1 of the Timeline:
var str1:String = "Bonjour";
var str2:String = "from";
var str3:String = "Paris";
var str4:String = str1.concat(" ", str2, " ", str3);
trace(str4); // Bonjour from Paris
3.
Select Control > Test Movie to test the Flash document.
If you use the addition (
string and a nonstring object, ActionScript automatically converts nonstring objects to strings
in order to evaluate the expression. This conversion is demonstrated in the following
code example:
var version:String = "Flash Player ";
var rel:Number = 8;
version = version + rel;
trace(version); // Flash Player 8
However, you can use parentheses to force the addition (+) operator to evaluate arithmetically,
as demonstrated in the following ActionScript code:
trace("Total: $" + 4.55 + 1.46); // Total: $4.551.46
trace("Total: $" + (4.55 + 1.46)); // Total: $6.01
You can use the
split()
based on a delimiter character. For example, you could segment a comma- or tab-delimited
string into multiple strings.
For example, the following code shows how you can split an array into substrings by using the
ampersand ( ) character as a delimiter.
