Loading More Entries According to the Users Screen Size

Loading More Entries According to the Users Screen Size

I'm a novice user of JQuery and there is something I want to do but I'm not sure whether JQuery can help me with this or not. Here is what I want to do:

Basically I have an on scroll feature that loads more entries when a user scrolls down. So I have that working, np there. But the problem is that the scroll bar doesn't show up on the page because the initial number of entries, onPageLoad aren't enough.

onPageLoad, I want to be able to dynamically add more entries according to the users screen size.

The following are the functions I have:

loadEntries() --> xmlhttpRequest that gets the data and appends it on the screen
getMaxEntries() --> xmlhttpRequest that gets the total number of entries that can be retrieved
$(window).scroll(function() --> calls loadEntries()

I also have <body onload="setup()">

setup() --> calls getMaxEntries(), here is where I would like call loadEntries() a few times (according to the screen size)

The only way I could get entries to load dynamically, onPageLoad was via a loop that called loadEntries() but that gave me an unresponsive script error, which I want to avoid.

Is there any way that JQuery can help me in solving this problem?
