The example in this article describes how jQuery can imitate the data loading effect of the Weibo drop-down scroll bar. Share it with everyone for your reference, the details are as follows:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>滚动条距离底部</title>
<script src="jquery-1.6.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
var i = 4;
$(window).bind("scroll", function (event) {
//滚动条到网页头部的 高度，兼容ie,ff,chrome
var top = document.documentElement.scrollTop + document.body.scrollTop;
//网页的高度
var textheight = $(document).height();
// 网页高度-top-当前窗口高度
if (textheight - top - $(window).height() <= 100) {
if (i >= 100) {
return; //控制最大只能加载到100
}
$('#div1').css("height", $(document).height() + 100);
i++;
//可以根据实际情况，获取动态数据加载 到 div1中
$('<div>' + i + '</div>').appendTo($('#div1'));
}
});
})
</script>
<style>
#div1 div{ font-size:100px; background:#ccc;margin-top:5px}
</style>
</head>
<body>
<form id="form1" runat="server">
<div style="height: 1000px;" id="div1">
<div>
1</div>
<div>
2</div>
<div>
3</div>
<div>
4</div>
</div>
</form>
</body>
</html>
I hope this article will be helpful to everyone in jQuery programming.
