新闻 Vue v2.0.0-alpha.7 发布，轻量级 JavaScript 框架 下载

Vue v2.0.0 alpha.7 发布了，Vue.js 是构建 Web 界面的 JavaScript 库，提供数据驱动的组件，还有简单灵活的 API，使得 MVVM 更简单。

主要特性：

• 
  可扩展的数据绑定
  
  
• 
  将普通的 JS 对象作为 model
  
  
• 
  简洁明了的 API
  
  
• 
  组件化 UI 构建
  
  
• 
  配合别的库使用
  

本次发布的一些新增特性及使用示例：

Breaking Changes

• 
  The init lifecycle hook has been renamed to beforeCreated.
  
  
• 
  JavaScript transition hooks now receive the context Vue instance as the second argument:
  

Vue.transition('example', {
onEnter (el, vm) {
// ...
}
})
New

• 
  $createElement can now omit the data argument if no data is needed. If the second argument is truthy and is not an Object, it will be treated as the children.
  
  
  

render (h) { // before
return h('div', null, 'hello') // after
return h('div', 'hello')
}

• 
  SSR: Now supports bundle renderer, which runs a pre-bundled app script in a fresh context for each render. This eliminates the need for structuring your application without global state just for the sake of server-side rendering.
  
  
• 
  SSR: Now supports component-level caching via server.getCacheKey option.
  
  
• 
  Vue.config.errorHandler now also captures errors thrown in user watcher callbacks.
  

Fixed

• 
  #3140 fix v-model .number conversion for non-number input
  
  
• 
  fix CSS animation initial frame flash
  
  
• 
  fix SSR client-side hydration on merged text nodes
  
  
• 
  #3155 fix v-once when used with v-for
  
  
• 
  #3157 fix id-resolved transition with appear: true
