For this site, http://www.dianping.com/shop/1898365 I am trying to figure out whats the latitude and longitude by crawling. But I cant seem to figure out where this information is stored. Can someone give me some pointers

Need a little more info here. What are you looking for? Elements in the page that were clicked? Or an element given by an id, name or class?

You can get the position of any element on a page by its offsetLeft and offsetTop by doing something like this:

var x =document.getElementById('myId').offsetLeft;
var y =document.getElementById('myId').offsetTop;

See this page:

or if you are using jquery:

var myOffset = $('#myId').offset();
var x = myOffset.left;
var y = myOffset.top;
