# Online & Offline Status API

## Overview

Online & Offline Status API allows web apps to detect whether the browser is online or offline.

## Demo

<https://nectar.website/demo/web-apis/online-offline-status/>

## Usage

You can refer to the code present in `/partials/web-apis/online-offline-status.html` file and use it accordingly.

By default, we have already implemented a functionality using this API. Whenever your app goes online or offline a toast message will appear.

The code is present in `/assets/custom/init.js` file. This code uses Framework7's `online` and `offline` events which are based on HTML5's `navigator.onLine`

```javascript
app.on('online', function() {

});

app.on('offline', function() {

});
```

## 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://pmsgz.gitbook.io/nectar/advanced/web-apis/online-offline-status.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.
