# 事件

在指定事件发生时执行脚本。value 是事件的名称。目前仅支持一个事件：`network-changed`。

请调用 `$done()` 以完成执行。

## 事件类型 (Event Types)

* `network-changed`: 当系统网络发生变化时触发。

```javascript
// network-changed = script-path=network-changed.js,type=event,event-name=network-changed

$notification.post('DNS Update', $network.dns.join(', '));

$done();
```

* `notification`: 当 Surge 显示通知时触发。即使通知所属的分类被关闭，脚本仍然可以获取该消息。

```javascript
// notification = script-path=notification.js,type=event,event-name=notification

console.log($event.data);

$done();
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://surge.mitsea.com/scripting/event.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
