(JavaScript) string.toCharCodes & String.fromCharCodes [JS 1.8]

Thu, 12 Mar 2009 19:58:56 GMT

*Requires JavaScript 1.8 or higher* Syntax: `Array string.toCharCodes()` returns an array containing every one of `string`'s character codes, in order. `String String.fromCharCodes(charCodes)` returns a string created from every character code in the array, `charCodes`.

(JavaScript) fn.call and fn.apply [JS 1.8]

Sat, 07 Mar 2009 13:15:22 GMT

*Requires JavaScript 1.8* fn.call and fn.apply are alternative methods to access function.call and function.apply and I don't see fn.call and fn.apply having any use but I made them for the heck of it. Syntax: `fn.call(function, [thisObject, [argument1, ..., argumentN]])` is equivalent to `function.call(thisObject, argument1, ..., argumentN)` `fn.apply(function, [thisObject, [argumentsArray]])` is equivalent to `function.apply(thisObject, argumentsArray)` Examples: function foo(a, b) (this*a)-b; fn.call(foo, 5, 6, 7) == 23 foo.call(5, 6, 7) == 23 fn.apply(foo, 5, [6, 7]) == 23 foo.apply(5, [6, 7]) == 23

(JavaScript) Get Accessor (Getter/Setter) [JS 1.8]

Thu, 05 Mar 2009 16:26:59 GMT

*Requires JavaScript 1.8* `$[gs]etter(obj, property)` returns `function() obj.__lookup[GS]etter__(property).apply(obj, Array.prototype.slice.call(arguments))` `object.get[GS]etter(property)` returns `$[gs]etter(this, property)` Useful for getting the getters and setters of objects like `location`, so you can do stuff like location.getSetter("hash") to get the native hash-changing function. Example: var foo = {a: 5} foo.__defineSetter__("bar", function(x) x/this.a) var fooBarSetter = foo.getSetter("bar") // $setter(foo, "bar") also works fooBarSetter(40) == 8 var changeHash = location.getSetter("hash") changeHash("test") var getHash = location.getGetter("hash") getHash() == location.hash getHash() == "#test" function changeInnerHTML(el, html) el.getSetter("innerHTML")(html) changeInnerHTML(document.body, "test") document.getSetter("title")("Test")

(JavaScript) base36 Encode/Decode [JS 1.8]

Fri, 27 Feb 2009 22:33:58 GMT

base36 Encode/Decode Strings ==================== *Requires JavaScript 1.8 or higher* Syntax: `base36[.ascii].encode(str[, separator]):String` `base36[.ascii].decode(str[, separator]):String` Default character separator is ZERO WIDTH SPACE U+200B Examples: base36.encode("foobar", "-") == "2u-33-33-2q-2p-36" base36.decode("2u-33-33-2q-2p-36", "-") == "foobar"

(JavaScript) object.forEach [JS 1.8]

object.forEach ========= *Requires JavaScript 1.8* `void object.forEach(function callback(item, value)[, thisObject])`

(JavaScript) Easy Namespacing (JS 1.8)

Mon, 23 Feb 2009 00:20:21 GMT

Easy Namespacing ================ *Requires JavaScript 1.8* Examples: `"foo.bar.baz".namespace()` makes `foo.bar.baz` `"foo::bar::baz".namespace("::")` makes `foo.bar.baz` `namespace.call(obj, ns[, separator])` extends `ns` (split by separator or ".") onto `obj`
