廢話不多說了，直接給大家貼js代碼了。
<!DOCTYPE html>
<html>
<head>
<script src="jquery-...js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var range = ; //距下邊界長度/單位px
var elemt = ; //插入元素高度/單位px
var maxnum = ; //設置加載最多次數
var num = ;
var totalheight = ;
var main = $("#content"); //主體元素
$(window).scroll(function () {
var srollPos = $(window).scrollTop(); //滾動條距頂部距離(頁面超出窗口的高度)
//console.log("滾動條到頂部的垂直高度: "+$(document).scrollTop());
//console.log("頁面的文檔高度 ："+$(document).height());
//console.log('浏覽器的高度：'+$(window).height());
totalheight = parseFloat($(window).height()) + parseFloat(srollPos);//滾動條當前位置距頂部距離+浏覽器的高度
if (($(document).height() - totalheight) <= range && num != maxnum) {//頁面底部與滾動條底部的距離<range
main.append("<div style='border:px solid tomato;margin-top:px;color:#ac" + (num % ) + (num % ) + ";height:" + elemt + "' >hello world" + srollPos + "---" + num + "</div>");
main.append("<div style='border:px solid tomato;margin-top:px;color:#ac" + (num % ) + (num % ) + ";height:" + elemt + "' >hello world" + srollPos + "---" + num + "</div>");
num++;
}
});
});
</script>
</head>
<body>
<div id="content" style="height:px">
<div id="follow">this is a scroll test;<br /> 頁面下拉自動加載內容</div>
<div style='border:px solid tomato;margin-top:px;color:#ac;height:'>hello world test DIV</div>
</div>
</body>
</html>
ps：原生JavaScript如何觸發滾動條事件?
<script>
window.onscroll = function(){
var scrollT = document.documentElement.scrollTop||document.body.scrollTop;
var scrollH = document.documentElement.scrollHeight||document.body.scrollHeight;
var clientH = document.documentElement.clientHeight||document.body.clientHeight
//console.log(scrollT +"+"+scrollH+"+"+clientH);
if(scrollT == scrollH - clientH){
console.log("到底部了");
}else if(scrollT == 0){
console.log("到頂部了");
}
}
</script>
