Below I will share with you an example of vue.js nested loop, if judgment, and dynamic deletion. It has a good reference value and I hope it will be helpful to everyone.

Vue.js is a very popular JavaScript MVVM library. It is built with data-driven and component-based ideas. Compared with Angular.js, Vue.js provides a simpler and easier-to-understand API

##The difference between vue1.0 and vue2.0 loop index use

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);
 }
}
