Get Function Name

/ Published in: JavaScript

Get Function Name
============

This will only return (a string) if the object passed to getFunctionName is a function or an "object" function from IE.
The function does not rely on function.name if present as it can't always be trusted.

Examples:

getFunctionName(function Foo(){}) == "Foo"
getFunctionName(function(){}) == ""

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

function getFunctionName(func) {
  if ( typeof func == "function" || typeof func == "object" )
  var fName = (""+func).match(
    /function\s*([\w\$]*)\s*\(/
  ); if ( fName !== null ) return fName[1];
}
