jQuery Mobile custom loader
Solution:
Working jsFiddle: http://jsfiddle.net/Gajotres/vdgB5/
Mobileinit
event must be initialized before jQuery Mobile is initialized and after jQuery. Also some additional changes to css must be done for this to work.
First of all, we need to override default ui-loader-default
class because its opacity is to low and final spinner is hard to see. Change opacity value how ever you want.
.ui-loader-default {
opacity: 1 !important;
}
And this is our spinner.
.custom-spinner {
width: 37px !important;
height: 37px !important;
background-image:url('http://pictures.reuters.com/ClientFiles/RTR/Images/ajax-loader.gif');
display: block;
}
Here's a working example:

Programmatic execution of jQuery mobile ajax loader
Some browsers, including webkit browser like Chrome have a programmatic execution of jQuery mobile ajax loader. They can be executed manually with serinterval, like this:
$(document).on('pagebeforecreate', '#index', function(){
var interval = setInterval(function(){
$.mobile.loading('show');
clearInterval(interval);
},1);
});
$(document).on('pageshow', '#index', function(){
var interval = setInterval(function(){
$.mobile.loading('hide');
clearInterval(interval);
},1);
});
