代码如下:RegExp.prototype.match = RegExp.prototype.test; RegExp.escape = function(str) { return String(str).replace(/([.*+?^=!:${}()|[\]\/\\])/g, '\\$1'); };就一个escape方法，就是把那几个特殊字符转义一下。 还有就是match方法是test方法的别名。 看一个例子: var str=RegExp.escape("+.[]$://!"); document.writeln(str) //==> "\+\.\[\]\$\:\/\/\!"
Ranges represent an interval of values. The value type just needs to be “compatible,” that is, to implement a succ method letting us step from one value to the next (its successor). Prototype provides such a method for Number and String, but you are of course welcome to implement useful semantics in your own objects, in order to enable ranges based on them. ObjectRange对象基本就是实现了连续的数字...
代码如下:Object.extend(Number.prototype, (function() { //返回十六进制颜色之 function toColorPart() { return this.toPaddedString(2, 16); } //返回连续的下一个数值 function succ() { return this + 1; } //连续执行某个操作 function times(iterator, context) { $R(0, this, true).each(iterator, context); return this; } //返回固定长度的字符串，前面补0 function toPaddedString(length, radix) { var string =...
代码如下:var Template = Class.create({ //初始化方法 initialize: function(template, pattern) { this.template = template.toString(); this.pattern = pattern || Template.Pattern; }, //格式化方法，如果从java的角度来说，其实叫format更好 :) evaluate: function(object) { //检查是否定义了toTemplateReplacements方法，是的话调用 //整个的Prototype框架中，只有Hash对象定义了这个方法 if (object && Object.i...
Enumerable provides a large set of useful methods for enumerations, that is, objects that act as collections of values. It is a cornerstone of Prototype. Enumerable is what we like to call a module: a consistent set of methods intended not for independent use, but for mixin: incorporation into other objects that “fit” with it. Quite a few objects, in Prototype, mix Enumerable in already. The mos...
代码如下://String对象的静态方法 Object.extend(String, { interpret: function(value) { return value == null ? : String(value); }, specialChar: { \b: \\b, \t: \\t, \n: \\n, \f: \\f, \r: \\r, \\: \\\\ } }); Object.extend(String.prototype, (function() { //内部方法，为gsub和sub函数初始化replacement参数 function prepareReplacement(replacement) { if (Object.isFunction(replacement)) return replacement; va...
This is a simple facility for periodical execution of a function. This essentially encapsulates the native clearInterval/setInterval mechanism found in native Window objects. This is especially useful if you use one to interact with the user at given intervals (e.g. use a prompt or confirm call): this will avoid multiple message boxes all waiting to be actioned. 这个对象就是可以周期性的执行某个方法...
代码如下://Hash对象的工具函数 function $H(object) { return new Hash(object); }; var Hash = Class.create(Enumerable, (function() { //初始化，创建一个新的Hash对象 function initialize(object) { this._object = Object.isHash(object) ? object.toObject() : Object.clone(object); } //覆盖Enumerable里面的方法，遍历Hash对象时会用到 function _each(iterator) { for (var key in this._object) { var value = this._...
代码如下:/* Based on Alex Arnell's inheritance implementation. */ var Class = (function() { //临时存储parent的prototype function subclass() {}; //创建类的方法 function create() { var parent = null, properties = $A(arguments); //检查新建一个类时，是否指定了一个父对象 //如果指定了父类，赋值给parent if (Object.isFunction(properties[0])) parent = properties.shift(); //真正用作返回的类，在创建实...

环境： Prototype Version: '1.6.1_rc3' Aptana Studio, build: 1.2.5.023247 IE7 FF2.0.0.4 Opera 10 beta 代码如下:var Prototype = { Version: '1.6.1_rc3', //定义浏览器对象 Browser: (function(){ var ua = navigator.userAgent; var isOpera = Object.prototype.toString.call(window.opera) == '[object Opera]'; return { IE: !!window.attachEvent && !isOpera, Opera: isOpera, WebKit: ua.indexOf('AppleWebKit/') > ...
$ $$ $A $F $H $R $w Try.these document.getElementsByClassName $方法——被成为瑞士军刀（Swiss Army knife） If provided with a string, returns the element in the document with matching ID; otherwise returns the passed element. Takes in an arbitrary number of arguments. All elements returned by the function are extended with Prototype DOM extensions. 代码如下:function $(element) { if (arguments.leng...
$w方法 Splits a string into an Array, treating all whitespace as delimiters. Equivalent to Ruby's %w{foo bar} or Perl's qw(foo bar). 代码如下:function $w(string) { if (!Object.isString(string)) return []; string = string.strip(); return string ? string.split(/\s+/) : []; } 这个方法就是用空白字符把字符串分成数组，然后返回。 例子： 代码如下:$w(apples bananas kiwis) // -> [apples, bananas, kiwis] $...
$A方法: Accepts an array-like collection (anything with numeric indices) and returns its equivalent as an actual Array object. This method is a convenience alias of Array.from, but is the preferred way of casting to an Array. 代码如下:function $A(iterable) { if (!iterable) return []; if ('toArray' in Object(iterable)) return iterable.toArray(); var length = iterable.length || 0, results = new Arr...
Object is used by Prototype as a namespace; that is, it just keeps a few new methods together, which are intended for namespaced access (i.e. starting with “Object.”). 上面说的namespace个人理解就相当于C#中的静态类，提供工具函数的意思，和C#中的namespace应该不是一个概念。因为C#中的命名空间后面不会直接跟方法，肯定是接一个对象然后在调用方法，不过和C++中的命名空间倒是有些类似 clone extend inspect isA...
