Flash Player 5 (became a native object in Flash Player 6, which improved performance significantly).
The Boolean object is a wrapper object with the same functionality as the standard JavaScript Boolean object. Use the Boolean object to retrieve the primitive data type or string representation of a Boolean object.
You must use the constructor new Boolean()
to create an instance of the Boolean object before calling its methods.
Method | Description |
---|---|
Boolean.toString() |
Returns the string representation (true) or (false) of the Boolean object. |
Boolean.valueOf() |
Returns the primitive value type of the specified Boolean object. |
Flash Player 5.
new Boolean([
x
])
x
Any expression. This parameter is optional.
Nothing.
Constructor; creates an instance of the Boolean object. If you omit the x
parameter, the Boolean object is initialized with a value of false
. If you specify a value for the x
parameter, the method evaluates it and returns the result as a Boolean value according to the rules in the Boolean (function) function.
Note: To maintain compatibility with Flash Player 4, the handling of strings by the Boolean object is not ECMA-262 standard.
The following code creates a new empty Boolean object called myBoolean
.
myBoolean = new Boolean();
