Adding Back Button to Header

Quiz

Description

jQuery mobile framework generates a back button on a header, when a header has a data-add-back-btn = "true" attribute or the page plugin's addBackBtn option is set to true.

Adding data-rel = "back" on an anchor will take you to the history entry, ignoring the default href.

You can provide the back button text using data-back-btn-text = "previous" attribute or you can set plugin's options in the following way.

$.mobile.toolbar.prototype.options.backBtnText = "previous";

Example
