The constructor property is specifies the function that creates an object.
Syntax
object.constructor
The required object argument is the name of an object or function.
Example
The constructor property is a member of the prototype of every object that has a prototype. This includes all intrinsic JavaScript objects except the Global and Math objects. The constructor property contains a reference to the function that constructs instances of that particular object. For example:
x = new String("Hi");
if (x.constructor == String)
{
// Do something (the condition will be true).
document.write("My name is Henry.");
}
|
or
function MyFunc()
{
var s="Hello world!";
return(s);
}
y = new MyFunc();
if (y.constructor == MyFunc)
document.write("Antechinus JavaScript Editor");
