Multiple-page html versus several single page html files

Multiple-page html versus several single page html files

I have an application that uses four different pages. On one is a map on which the user can add markers when these markers are added the coordinates are written to a second page. The user can add other parameters to a third page and the results of calculations using the coordinates and parameters are displayed on a fourth page. 

Using a multiple page layout makes this simple as all of the input boxes, selection boxes etc are available in the DOM. I have read that using single page html files for each page is the preferred method of writing JQMobile apps but how can I share the data between the pages?

Can I assume that a multiple-page html layout is better for an application such as mine?
