As long as you are setting an accessor on the window object, a DOM element, or a DOM prototype, Xccessors should work fine in every browser. Xccessors Standard ------------------ Xcessors Standard implements ECMAScript 5's (formerly 3.1) `Object.defineProperty`, `Object.defineProperties`, and `Object.getOwnPropertyDescriptor` in browsers that support the legacy non-standard accessor methods. Everything behaves according to the ECMAScript 5 standard except the configurable, enumerable, and writable options if set to `false`. It is impossible to implement these options without native support for `Object.defineProperty`. The good news is that you are never going to use them if you are changing a JavaScript program from the legacy to standard methods. Xccessors Legacy ---------------- Xccessors Legacy implements the legacy accessor methods (`object.__define[GS]etter__` and `object.__lookup[GS]etter__`) in browsers that support the standard ECMAScript 5 accessor methods. Supported Platforms ------------------- * SpiderMonkey (Firefox, all Gecko browsers) * JavaScriptCore (Safari, many WebKit-based browsers) * V8 (Google Chrome, Chromium) * Futhark (Opera 9.5) * Carakan (Opera 10.5) * JScript 1.5 (Internet Explorer 8; DOM elements and prototypes only) * Chakra (Internet Explorer 9) * Rhino * Narcissus ![Tracking image](https://in.getclicky.com/212712ns.gif =1x1)
