<uploaddata-div ref="RefuploadDataNwt" v-bind:roles="roles" @callbackfun="getUploadDataNwt"></uploaddata-div>的作用
时间: 2023-10-14 15:06:16 浏览: 52
`<uploaddata-div>` 是一个自定义组件,通过 `v-bind:roles="roles"` 将 `roles` 变量传递给该组件。同时,使用 `@callbackfun="getUploadDataNwt"` 绑定了一个名为 `callbackfun` 的自定义事件,并将 `getUploadDataNwt` 方法作为事件处理函数。
这个自定义组件的作用可能是实现文件上传功能。根据命名可以猜测它可能是一个包含了文件上传相关逻辑的组件,通过使用 `ref` 属性将其引用保存在当前组件中,从而可以在其他地方直接访问该组件的实例。
当 `<uploaddata-div>` 组件内部触发了 `callbackfun` 事件时,会调用绑定的 `getUploadDataNwt` 方法,实现自定义的回调逻辑。你可以在 `getUploadDataNwt` 方法中处理上传数据的逻辑或者执行其他自定义操作。
请注意,由于我是一个文本AI模型,无法直接运行代码或查看你的具体实现。以上只是对代码逻辑的猜测和推测。具体的作用和功能还需要参考你的代码实现或者相关文档来确定。

这段代码中,第7行和第8行的`van-button`标签的结束标签的斜杠`/`被误删了,导致编译错误。你可以在这两个标签的结尾加上斜杠`/`即可解决问题。修改后的代码如下所示:
```
<van-cell-group>
<van-field model:value="{{ productKey }}" label="productKey:" />
<van-field model:value="{{ deviceName }}" label="deviceName:" />
<van-field model:value="{{ deviceSecret }}" label="deviceSecret:" />
</van-cell-group>
<van-divider />
