新闻 Vue.js 1.0.0 beta4 发布，轻量级 JavaScript 框架 下载

Vue.js 1.0.0 beta4 发布，首个 RC 版本计划在下周发布，十月底发布正式版。

1.0 文档预览：rc.vuejs.org

相比 1.0.0-beta.3，改进如下：

重大改进

• 
  Vue no longer extends Object.prototype with $set and $delete methods.
  
  
• 
  Instance method vm.$addChild() has been deprecated.
  
  
• 
  The global config proto has been deprecated.
  
  
• 
  v-for no longer uses track-by="$index" behavior for Arrays of primitive values by default.
  
  
• 
  v-for no longer converts the value to Array before piping it through filters.
  
  
• 
  The orderBy filter now expects its second argument to be a number instead of a boolean.
  
  
• 
  Global asset registration methods, e.g. Vue.component, now returns the registered asset.
  

改进

• 
  v-on can now handle multiple key modifiers:
  
  <input @keyup.enter.esc="onEnterOrEsc">
• 
  Directive modifiers are now exposed to custom directive instances as this.modifiers:
  
  <div v-my-directive.one.two="xxx">
  
  Vue.directive('my-directive', { bind: function () { this.modifiers.one // -> true
  this.modifiers.two // -> true
  }
  })

Bug 修复

• 
  #1398 Use more reliable visibility check for transitions. This fixes situations where elements are stuck on leave if the parent element is not visible.
  
  
• 
  #1399 Modifiers are no longer included in this.arg for custom directives.
  
  
• 
  #1400 only warn twoWay prop binding type mismatch when the prop is present.
