一、js部分：
<script type="text/javascript">
$(document).ready(function () {
$("#scroll").scroll(function () {
Form1.divScrollValue.value = $("#scroll").scrollTop();
});
});
function ScrollToSelectNode() {
document.getElementById("scroll").scrollTop = "<%=ScrollValue%>";
}
</script>
二、HTML部分
<body onload="ScrollToSelectNode()">
<input runat="server" id="divScrollValue" type="hidden" value="" />
<div class="air_1_2_1_2">
<div class="air_1_2_1_2_1">摄像相列表</div>
<div class="air_1_2_1_2_2" id="scroll">
<TABLE id="CameraTable" cellSpacing="0" cellPadding="0" width="100%" border="0" runat="server"></TABLE>
</div>
</div>
</body>
三、C#后台：
public static string ScrollValue = string.Empty;//滚动条位置
protected void Page_Load(object sender, EventArgs e)
{
ScrollValue = divScrollValue.Value;
}
