内容页面-会话值的javascript值 [英] Content page - javascript value to Session variable

目前，我正在C.3.5中使用asp.net.
我正在使用母版页.
在这里，我需要捕获浏览器的本地时间，并希望在页面加载时将其存储在会话变量中.我正在使用以下javascript代码
currently i m using asp.net with C# 3.5.
i m using master page.
here i need to capture the browser local time and want to store in session variable in page load. i m using following javascript code
<script language="javascript" type="text/javascript">

{
var now = new Date()
var offset = now.getTimezoneOffset()
document.getElementById('<%=hidTime.ClientID%>').value = offset
}
</script>
调用函数为:< body onload ="GetClientUTC()">
并在页面加载中按以下方式分配
calling function as : <body onload="GetClientUTC()">

推荐答案
您要么需要通过AJAX回发将其发送，要么将其设置为cookie并在下一页请求中将其读出，或者执行所有在客户端进行处理，或者让用户在配置文件中设置其本地时区并在服务器端进行计算.
最简单的方法是在首页/登录页面上设置Cookie(有效期很短，即1天)，然后读取该Cookie. (我认为JavaScript仍然可以编写发送回服务器的cookie.)
You either need to send it via an AJAX postback, or set it in a cookie and read that out in the next page request, or do all the processing with it client side, or have the user set their home time zone in a profile and calculate it on the server side.
The easiest way is to set a cookie (with a fairly short i.e. 1 day expiry) on the home/login page and read that. (I think JavaScript can write cookies that are sent back to the server, anyway.)
添加
runat='server'属性的控件，您在上面的javascript代码中为其设置了值.
希望我能解决您的问题
attribute to the control whose value you are setting in the javascript code above.
I hope I was able to solve your problem
