</html>del方法里，打印了一个this值。
f12开发者模式，默认显示的打印结果是
Vue {_uid: 0, _isVue: true, $options: {…}, _renderProxy: Proxy, _self: Vue, …} (未展开）
问题是，是否可能在未展开的状态下，搜索到 name:"宝马" 存在哪个地方？
现在我只能手动展开，找到，
Vue {_uid: 0, _isVue: true, $options: {…}, _renderProxy: Proxy, _self: Vue, …}
$attrs: (...)
$listeners: (...)
list: Array(1)
0:
id: 2
name: "宝马"有啥快捷键吗？
谢谢~~~

装vue-devtools最方便。
不然就打印具体的this.list
