这次给大家带来使用vue.js的嵌套循环、if判断、动态删除图文详解,使用vue.js的嵌套循环、if判断、动态删除的注意事项有哪些,下面就是实战案例,一起来看一下。

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

app.html

使用vue.js的嵌套循环、if判断、动态删除图文详解

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);
 }
}
