Question

I am trying to determine the previous page (e.g. the referrer) in order to decide whether to display the back button.

I tried to check for $('.current').data('referrer'), but it is not always set. In fact, it is often not set. history.previous and document.referrer do not seem to be set, either.

Could someone please enlighten me on this?

Answer 1

I didn’t want to go down this path, but the only viable solution I can find is the internal variable (i.e. hist) that jQTouch keeps the browsing history. So, I made the following changes to jqouth.js (revision 146):

around line 256, just before the private functions section, insert:

function getHistory() { return hist; }

around line 625, just before submitForm: submitForm, insert:

getHistory: getHistory,

Then I can look at the browsing history with something like:

var previousPageID = jQT.getHistory()[1].id;

One caveat is, care should be taken not to accidentally maniplulate the history object.

EDIT:

The author has exposed the internal history object since the version on 14 October 2010, so it can be directly accessed, i.e. jQT.hist.
