Vue.js是当下很火的一个JavaScript MVVM库，它是以数据驱动和组件化的思想构建的。相比于Angular.js，Vue.js提供了更加简洁、更易于理解的API

vue1.0和vue2.0循环索引使用区别


如果是vue1.0这样写：
<ol>
 <li v-for="todo in todos" @click="delete($index)">
 {{todo.label}}
 </li>
</ol>
然后：
methods:{
 
 delete:function(index){
 this.todos.splice(index,1);
 }
}
如果是vue2.0这样写：
<ol>
 <li v-for="(todo,index) in todos" @click="delete(index)">
 {{todo.label}}
 </li> 
</ol>
然后
methods:{
 
 delete:function(index){
 this.todos.splice(index,1);
 }
}
