Vue.js 1.0.0 RC2 发布，更新如下： 新增 v-for now support the v-for="(key, val) in obj" or v-for="(index, val) in arr" syntax. This allows nested loops to more easily reference the key or index. v-on can now omit the expression if it has modifiers. e.g. @submit.prevent will call preventDefault() on submit events. Custom directive API improvement: Custom directives can now provide a params Array, and the Vue compiler will automatically extract these attributes on the element that the directive is bound to. The old undocumented this.param() directive instance method has been deprecated. Example: <div v-example a="hi"></div> Vue.directive('example', { params: ['a'], bind: function () { console.log(this.params.a) // -> "hi" } }) This API also supports dynamic attributes. The this.params[key] value is automatically kept up-to-date. In addition, you can specify a callback when the value has changed: <div v-example :a="someValue"></div> Vue.directive('example', { params: ['a'], paramWatchers: { a: function (val, oldVal) { console.log('a changed!') } } }) 修复 #1431 props with the same name not properly merged #1440 v-for components detach hook not called #1442 directives on a child component root not resolved in the right scope #1458 :class array syntax not removing stale classes 下载页面：1.0.0-rc.2 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 支持的浏览器：https://saucelabs.com/u/vuejs Vue.js 1.0.0 RC2 发布，轻量级 JavaScript 框架下载地址
