String function
String(expression:Object) : String
Returns a string representation of the specified parameter, as described in the following list:
■ If expression is a number, the return string is a text representation of the number.
■ If expression is a string, the return string is expression.
■ If expression is an object, the return value is a string representation of the object
generated by calling the string property for the object or by calling
Object.toString() if
no such property exists.
■ If expression is a Boolean value, the return string is "true" or "false".
■ If expression is a movie clip, the return value is the target path of the movie clip in slash
(/) notation.
If
expression is undefined, the return values are as follows:
■ In files published for Flash Player 6 or earlier, the result is an empty string ("").
■ In files published for Flash Player 7 or later, the result is undefined.
Note:Slash notation is not supported by ActionScript 2.0.
Availability: ActionScript 1.0; Flash Lite 1.0 - Behavior changed in Flash Player 7.
Parameters
expression:Object - An expression to convert to a string.
Returns
String - A string.
Example
In the following example, you use ActionScript to convert specified expressions to a string:
var string1:String = String("3");
var string2:String = String("9");
trace(string1+string2); // output: 39
Because both parameters are strings, the values are concatenated rather than added.
