METHOD:
Function::toString
Function.toString
()
The toString method returns a string which represents the source
code of a function. This over-rides the Object.toString
method. There are times when a function needs to be represented as a
string, and the toString method is automatically called to do
that. In this next example, the document.write statement requires
the function Car to be represented as a string, so JavaScript automatically
calls the toString method to produce the following output:
Code:
function car(make, model, year)
{this.make = make, this.model = model, this.year = year}
document.write(car)
Output:
function car(make, model, year) {this.make = make,
this.model = model, this.year = year
With the built-in Function object the toString method
would produce the following string: function Function()
{ [native code] }.
