vue2.0: bower info vue http://vuejs.org/ 到了2.0以后,有哪些变化? 1. 在每个组件模板,不在支持片段代码 组件中模板: 之前: <template> <h3>我是组件</h3><strong>我是加粗标签</strong> </template> 现在: 必须有根元素,包裹住所有的代码 <template id="aaa"> <div> <h3>我是组件</h3> <strong>我是加粗标签</strong> </div> </template> 2. 关于组件定义 Vue.extend 这种方式,在2.0里面有,但是有一些改动,这种写法,即使能用,咱也不用——--------废弃 Vue.component(组件名称,{ 在2.0继续能用 data(){} methods:{} template: }); 2.0推出一个组件,简洁定义方式: var Home={ template:‘‘ -> Vue.extend() }; 3. 生命周期 之前: init created beforeCompile compiled ready √ -> mounted beforeDestroy destroyed 现在: (创建----编译-----更新------销毁) beforeCreate 组件实例刚刚被创建,属性都没有 created 实例已经创建完成,属性已经绑定 beforeMount 模板编译之前 mounted 模板编译之后,代替之前ready * beforeUpdate 组件更新之前 updated 组件更新完毕 * beforeDestroy 组件销毁前 destroyed 组件销毁后
