Function.prototype.toSource Redirect 1

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Summary

The toSource() method returns a string representing the source code of the object.

Syntax

function.toSource();
Function.toSource();

Parameters

None.

Description

The toSource method returns the following values:

  • For the built-in Function object, toSource returns the following string indicating that the source code is not available:
    function Function() {
        [native code]
    }
  • For custom functions, toSource returns the JavaScript source that defines the object as a string.

This method is usually called internally by JavaScript and not explicitly in code. You can call toSource while debugging to examine the contents of an object.

Specifications

Not part of any standard. Implemented in JavaScript 1.3.
