The difference between vue1.0 and vue2.0 loop index usage
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);
}
