    Changelog

    React Core

    重大改进


    • key and ref moved off props object, now accessible on the element directly


    • React is now BSD licensed with accompanying Patents grant


    • Default prop resolution has moved to Element creation time instead of mount time, making them effectively static


    • React.__internals is removed - it was exposed for DevTools which no longer needs access


    • Composite Component functions can no longer be called directly - they must be wrapped with React.createFactory first. This is handled for you when using JSX.
    新特性


    • Spread operator ({...}) introduced to deprecate this.transferPropsTo


    • Added support for more HTML attributes: acceptCharset, classID, manifest
    废弃


    • React.renderComponent --> React.render


    • React.renderComponentToString --> React.renderToString


    • React.renderComponentToStaticMarkup --> React.renderToStaticMarkup


    • React.isValidComponent --> React.isValidElement


    • React.PropTypes.component --> React.PropTypes.element


    • React.PropTypes.renderable --> React.PropTypes.node


    • DEPRECATED React.isValidClass


    • DEPRECATED instance.transferPropsTo


    • DEPRECATED Returning false from event handlers to preventDefault


    • DEPRECATED Convenience Constructor usage as function, instead wrap with React.createFactory


    • DEPRECATED use of key={null} to assign implicit keys
    Bug 修复


    • Better handling of events and updates in nested results, fixing value restoration in "layered" controlled components


    • Correctly treat event.getModifierState as case sensitive


    • Improved normalization of event.charCode


    • Better error stacks when involving autobound methods


    • Removed DevTools message when the DevTools are installed


    • Correctly detect required language features across browsers


    • Fixed support for some HTML attributes:


      • list updates correctly now


      • scrollLeft, scrollTop removed, these should not be specified as props

    • Improved error messages
    React With Addons

    新特性


    • React.addons.batchedUpdates added to API for hooking into update cycle
    重大改进


    • React.addons.update uses assign instead of copyProperties which does hasOwnProperty checks. Properties on prototypes will no longer be updated correctly.
    Bug 修复


    • Fixed some issues with CSS Transitions
    JSX

    重大改进


    • Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components


    • JSX no longer transforms to simple function calls
    新特性


    • @jsx React.DOM no longer required


    • spread ({...}) operator introduced to allow easier use of props
    Bug 修复


    • JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)

    React.js 是 Facebook 推出的一个用来构建用户界面的 JavaScript 库。

    Facebook开源了React,这是该公司用于构建反应式图形界面的JavaScript库,已经应用于构建Instagram网站及 Facebook部分网站。最近出现了AngularJS、MeteorJS 和Polymer中实现的Model-Driven Views等框架,React也顺应了这种趋势。React基于在数据模型之上声明式指定用户界面的理念,用户界面会自动与底层数据保持同步。与前面提及 的框架不同,出于灵活性考虑,React使用JavaScript来构建用户界面,没有选择HTML。
