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
app.html
<!doctype html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>

</style>

##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);
}
}
