删除类实例

Question

我正在尝试删除类的实例。

我有一个<button>标记，其中包含一个事件监听器类方法remove：

<msg-item>
    <span>username: {{this.username}}</span>
    <p>message: {{this.message}}</p>
    <button ng-click="$ctrl.remove()">delete</button>
<msg-item>
<msg-item>
    <span>username: {{this.username}}</span>
    <p>message: {{this.message}}</p>
    <button ng-click="$ctrl.remove()">delete</button>
<msg-item>
<msg-item>
    <span>username: {{this.username}}</span>
    <p>message: {{this.message}}</p>
    <button ng-click="$ctrl.remove()">delete</button>
<msg-item>

班级：

class msgItemCtrl{
    constructor(){
        this.username = "johndoe";
        this.message = "hello world";
    }
    remove(){
        console.log('FIRING: Class Method (remove)');
        delete this;
    }
}

问题：如何从界面中删除类的实例以及关联的HTML？
