Type Recognition

TYPE RECOGNITION

var a = { value: "I am an object", toString: function () { return this.value; } }; var b = new String("I am a string"); alert(a); el.html(a); alert(b); el.html(b);

var extendWithName = function (object, name) { if (typeof object == "object") { object.name = name; } };

extendWithName(null, "null"); var a = function () {}; extendWithName(a, "function");

WHAT IS YOUR TYPE?

ARE YOU AN OBJECT?

ARE YOU A NUMBER?

var is = function (o, type) { type = (type + "").toLowerCase(); return (type == "object" && o === Object(o)) || (type == "undefined" && typeof o == type) || (type == "null" && o == null) || Object.prototype.toString.call(o) .slice(8, -1).toLowerCase() == type; };

THANK YOU
