HTML5 App with LocalStorage and webservice request-response (JSON)

One form text input field that with autofocus.

The app will be used on a handheld barcode scanner. Every time a barcode is scanned in the text input field, the device automatically submits the form.

Data is sent to server in JSON format.

Everytime text from the input field is submitted, it will also be saved in LocalStorage.

Server will send a response (JSON) with OK status for specific text.

The device updates entry in LocalStorage with OK status.

When there are entries in LocalStorage that have status offline, then after user gets back online a button can be pressed to upload offline data to server.
