<%@ Page SmartNavigation=ture %>
SmartNavigation=ture
加上这个好象整个页面都变的乱七八糟的，原来引用的CSS文件都失效了，字体乱成一团，TABALE里面的组件也东一个西一个
//使用cookie ,js:
<script id=clientEventHandlersJS language=javascript>
<!--
window.onload =function() {
if(getcookie("height")!=null)
document.body.scrollTop=getcookie("height");
}
window.onunload =function () {
setcookie("height",document.body.scrollTop);
}
function getcookie(sName)
{
var aCookie = document.cookie.split("; ");
for (var i=0; i < aCookie.length; i++)
{
var aCrumb = aCookie[i].split("=");
if (sName == aCrumb[0])
return unescape(aCrumb[1]);
}
return null;
}
function setcookie(sName, sValue)
{
date = new Date();
date.setTime(date.getTime()+60000); //1 minute
document.cookie = sName + "=" + escape(sValue) + "; expires=" + date.toGMTString();
}
//-->
</script>
设置SmartNavigation=ture（页面或者config中）会有异常情况，以下方法可以解决该问题
环境为VS.NET 2000和VS.NET 2003通过
<script language="javascript">
function GetCookie (name)
{
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen)
{
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function getCookieVal (offset)
{
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function SetCookie (name, value)
{
document.cookie = name + "=" + escape (value)
}
</script>
在body中加入
<body bgColor="#f1f5f5" leftMargin="0" topMargin="0" rightMargin="0" MS_POSITIONING="GridLayout" onload="document.body.scrollTop=GetCookie('posy')" onunload="SetCookie('posy',document.body.scrollTop)">
