javascript - jqm data-rel="back" issue -

imagine following scenario:

i have jquery-mobile formular, it´s results linking resultpage.

on resultpage have button:

<a href="#" data-rel="back" data-role="button"></a> 

this works fine update content , keep submitted form data,

but if user came search-engine or similiar extern link, button links searchengine/externlink .

so how differentiate between came form or anywhere else in jqm-way ?

i have "start-search-page" love link if user didn´t came search , don´t want miss ajax-link search resultpage, use same button , idealy don´t have set cookie.

is there hint or smarter attempt check server url document.referrer ? in advance

you can check current page url using below code:

var prevurl = $.mobile.activepage.data('url'); 

in case u want perform different actions based on previous url. on save url in global javascript variable , on click of button check previous url , functionality. eg

before navigating page:

var prevurl = $.mobile.activepage.data('url'); 

on click of button:

if (prevurl=="myurl") { //do  $.mobile.changepage('#search') } else {  $.mobile.changepage('#nothing') }
