The Boolean object is used to convert a
non-Boolean value to a Boolean value (true or false).
Tip: You will find more examples in the Boolean
object reference - look at the bottom of this page!
Boolean Object
The Boolean object is an object wrapper for a Boolean value.
The Boolean object is used to convert a non-Boolean value to
a Boolean value (true or false).
We define a Boolean object with the new keyword. The
following code line defines a Boolean object called myBoolean:
var myBoolean=new Boolean()
|
Note: If the Boolean object has no initial value or if
it is 0, -0, null, "", false, undefined, or NaN, the object is
set to false. Otherwise it is true (even with the string
"false")!
All the following lines of code create Boolean objects with
an initial value of false:
var myBoolean=new Boolean()
var myBoolean=new Boolean(0)
var myBoolean=new Boolean(null)
var myBoolean=new Boolean("")
var myBoolean=new Boolean(false)
var myBoolean=new Boolean(NaN)
|
And all the following lines of code create Boolean objects
with an initial value of true:
var myBoolean=new Boolean(true)
var myBoolean=new Boolean("true")
var myBoolean=new Boolean("false")
var myBoolean=new Boolean("Richard")
