Convert Boolean to Numeric

[Pachydermitis]

Hi all,
This has got to be easy, but it's got me going bald.
How do I convert a Boolean to a numberic value? This value is going
to a hidden field that is going to an SQL server. There has to be an
elegant way to change true to 1 and false to 0.
Thanks

var b = true;
var x= b?1:0;

Even simpler:
var x = +b;

The unary plus converts its operand to a number.

JavaScript is not Java, its casting syntax is narrowed.
As 'kaeli' said, the simplest is:
myElement.value = (x)?1:0;
And what is not elegant in this?

Since +x will do the conversion, your method is tediously long-winded
and untidy. It is certainly not simplest.
