每当我为懒惰滚动添加以下代码到我的index.xhtml时，我都会遇到异常
<script type="text/javascript">
$(document).ready(function(){
function lastAddedLiveFunc()
{
$('div#lastPostsLoader').html('<img src="bigLoader.gif">');
$.get("loadmore.php", function(data){
if (data != "") {
//console.log('add data..');
$(".items").append(data);
}
$('div#lastPostsLoader').empty();
});
};
//lastAddedLiveFunc();
$(window).scroll(function(){
var wintop = $(window).scrollTop(), docheight = $(document).height(), winheight = $(window).height();
var scrolltrigger = 0.95;
if ((wintop/(docheight-winheight)) > scrolltrigger) {
//console.log('scroll bottom');
lastAddedLiveFunc();
}
});
});
