JavaScript Boolean prototype constructor
Examples
Create a new method for the Boolean object:
Boolean.prototype.myColor = function ()
{
if (this.valueOf () == true)
{
this.color = "green";
}
else
{
this.color = "red";
}
}
{
if (this.valueOf () == true)
{
this.color = "green";
}
else
{
this.color = "red";
}
}
Create a Boolean object and add myColor methods:
var a = new Boolean (1);
a.myColor ();
var b = a.color;
a.myColor ();
var b = a.color;
b Results output:
green
try it"
