(JavaScript) Multiline Strings [JS 1.6] - Sephr

Sun, 05 Apr 2009 22:15:28 UTC

*Requires JavaScript 1.6 or higher* Syntax: `mutilineString(_ processing instruction_)` **Note**: The string processing instruction cannot include ?> in the string and does not support escaped characters (ie. \u0000) Example: var string = LEFT-ANGLE-BRACKET?string foo bar baz?RIGHT-ANGLE-BRACKET; mutilineString(string) == "foo\nbar\nbaz" Due to a problem with Snipplr, I can't put processing instructions in the comments. Replace LEFT-ANGLE-BRACKET with < and replace RIGHT-ANGLE-BRACKET with >

(Regular Expression) Get HTML5 origin - Sephr

Sun, 29 Mar 2009 17:27:41 UTC

Use this to extract an HTML5 origin from a URI. $1 is the origin. The square brackets are there to support IPv6 addresses. Example: var html5OriginRegex = /^([\w-]+:\/*\[?[\w\.:-]+\]?(?::\d+)?).*/; "http://www.google.com:42/foo/bar/baz.html".replace(html5OriginRegex, "$1") == "http://www.google.com:42"

(JavaScript) ErrorConstructor - Sephr

Sun, 29 Mar 2009 00:27:52 UTC

ErrorConstructor produces error constructors that behave the same way as the seven native error constructors. Usage: `ErrorConstructor([constructorName])` *If no constructorName is specified, the default of `Error.prototype.name` is used* Usage for generated error constructor: `errorConstructor([message[, location[, lineNumber]])` Examples: var SecurityError = ErrorConstructor("Security Error"), MarkupError = ErrorConstructor("(X)HTML Markup Error"); //these will both throw a SecurityError starting with "Security Error on line 83:" var xss_error = "Possible XSS Vector\n\ JSON XHR response parsed with eval()\n\ Recommended fix: Parse JSON with JSON.parse"; throw new SecurityError(xss_error, "/js/searchResultsJSONloader.js", 83); throw SecurityError(xss_error, "/js/searchResultsJSONloader.js", 83); //these will both throw the following MarkupError: //"(X)HTML Markup Error on line 1: Invalid DOCTYPE" throw new MarkupError("Invalid DOCTYPE"); throw MarkupError("Invalid DOCTYPE");

(JavaScript) Cross-browser Getters/Setters (including IE) - Sephr

Thu, 12 Mar 2009 20:33:41 UTC

Xccessors is a JavaScript shim that implements the legacy methods for defining and looking up object accessors (getters and setters) of objects in JavaScript using ECMAScript 3.1â€™s accessors standard. This is aimed at adding support for the legacy method in IE8 RC1. The code is made to have as small of a footprint as possible. YUI minified, the code is 556 bytes. Here is the minified version: (function(b,d,c){function a(f,g,e){if(f in d&&!(g in {})){d[c][g]=Element[c][g]=Window[c][g]=HTMLDocument[c][g]=e}}a(b[0],b[2],function(f,e){d[b[0]](this,f,{get:e})});a(b[0],b[3],function(f,e){d[b[0]](this,f,{set:e})});a(b[1],b[4],function(e){return d[b[1]](this,e).get||d[b[1]](this.constructor.prototype,e).get});a(b[1],b[5],function(e){return d[b[1]](this,e).set||d[b[1]](this.constructor.prototype,e).set})})(["defineProperty","getOwnPropertyDescriptor","__defineGetter__","__defineSetter__","__lookupGetter__","__lookupSetter__"],Object,"prototype");

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

Thu, 12 Mar 2009 19:58:56 UTC

*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) string.toCharCodes & String.fromCharCodes [JS 1.6] - Sephr

Thu, 12 Mar 2009 19:58:52 UTC

*Requires JavaScript 1.6 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 - Sephr

Sat, 07 Mar 2009 13:15:30 UTC

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) { return (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) - Sephr

Thu, 05 Mar 2009 16:30:19 UTC

`$[gs]etter(obj, property)` returns `function() { return obj.__lookup[GS]etter__(property).apply(obj, Array.prototype.slice.call(arguments)) }` `object.get[GS]etter(property)` returns `$[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) { return 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) { return el.getSetter("innerHTML")(html) } changeInnerHTML(document.body, "test") document.getSetter("title")("Test")

Mon, 23 Feb 2009 00:59:57 UTC

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

(JavaScript) Get Function Name - Sephr

Mon, 23 Feb 2009 00:39:00 UTC

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(){}) == ""

(JavaScript) Easy Namespacing - Sephr

Easy Namespacing ================ This version doesn't require 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`
