Sencha Touch Cookbook

Detecting offline mode

The life of an offline application starts with identifying whether the device/browser is online or offline and, based on that, taking the appropriate action. In this recipe, we will see the different ways that we can identify whether the device or the browser is online or offline, which would help us make decisions in the subsequent recipes. We will start with using PhoneGap API to detect the mode and then later look at other alternatives.

We have already set up our project with PhoneGap support as part of the setup in Chapter 1. You may refer to http://docs.phonegap.com for more details on its APIs.
