elementui @open=handleOpen @close=handleClose

As an AI language model, I cannot provide a complete answer without additional context. However, it seems that this code is using ElementUI, a Vue.js based UI toolkit, to create a component that has two event handlers: `handleOpen` and `handleClose`. The `@open` and `@close` directives are used to bind these event handlers to the corresponding events triggered by the component.

For example, if the component is a modal dialog, `handleOpen` might be called when the modal is opened, while `handleClose` might be called when the modal is closed. These event handlers can be used to perform certain actions or update the component's state when the corresponding events occur.
