如何在vue中使用继承了Array的子类

[Diry2017]

如果在VUE组件中使用继承了Array的子类
只要改对象赋值进入VUE组件中 VUE会把该对象改为VUE能够监听的对象

1. list类 继承 Array
   export class List extends Array {
constructor(){
super()
}
test()
}
}

2.某个VUE组件中
import { List } from './list'
export default {
data () {
return {
list: null
}
},
created () {
this.list = new List()
console.log(new List().test) // => function....
console.log(this.list.test) // => undefined
}
}
