新闻 Vue v2.0.0-alpha.5 发布，轻量级 JavaScript 框架 下载

Vue v2.0.0-alpha.5 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
  

新增特性及使用示例：

• 
  The render function now receives the component instance's $createElement method as its only argument. This avoids having to aliasing this.$createElement to something less verbose:
  
  Vue.extend({
  render (h) {
  return h('div', null, 'hello!')
  }
  })
• 
  Functional components:
  
  A component can be defined as a stateless functional component with functional: true.
  
  
  • 
    createElement: the parent component's $createElement method.
    
    
  • 
    props: an object containing props
    
    
  • 
    children: children inside the component's tag as vnodes
    
    
  • 
    A functional component has no instance and is simply a function that receives props and children vnodes via arguments, and also return vnode(s).
    
    
  • 
    Unlike stateful components, functional components are not restricted by the "single root node" rule and can return an Array of multiple vnodes.
    
    
  • 
    A functional component's render function receives the following arguments:
    
  
  Example usage:
  
  Vue.component('wrap-with-tag', {
  functional: true,
  props: ['tag'], render (h, props, children) {
  return h(props.tag, null, children)
  }
  })
  
  When used in template:
  
  <wrap-with-tag tag="div">hello</wrap-with-tag>
  
  Will render:
  
  <div>hello</div
