I think we all know that In IE, typeof window.alert , returns “object” Here is my portable isFunction() , IMHO it might be ine of the simplest solutions that I have seen?
// GPL (c) 2009 by DBJ.ORG var isFunction = typeof (top.alert) == "object" ? function(x) { return (x + "").match(/function/) !== null ; } : function (x) { return x instanceof Function; } // test isFunction( window.alert ) // returns true, in all browsers Enjoy … --DBJ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jQuery Development" group.
