问题描述
大家好，
我想要获取客户的机器日期&时间。
我用javascript这样做，
代码：
Hi guys,
I want to fetch client's machine date & time.
I have used javascript to do so,
code:
var currentTime = new Date();
var fulldate = currentTime.getFullYear()
+ '-' + currentTime.getMonth() + 1
+ '-' + currentTime.getDate()
+ ' ' + currentTime.getHours()
+ ':' + currentTime.getMinutes()
+ ':' + currentTime.getSeconds()
+ ':' + currentTime.getMilliseconds();
<% Session["CDATE"] = "'" + fulldate + "'" %>
但是，遗憾的是= =fulldate，就像字符串一样，我提供变量名称。
Plz建议我做什么...
谢谢
But, unfortunately sessions = "fulldate", like as string, where as i'm providing the variable name.
Plz suggest me what to do...
thanks
推荐答案
你是什么由于您的fulldate变量已初始化为客户端，但会话[CDATE]被分配给服务器端，因此无法正常工作。
创建一个页面，将您的fulldate作为查询字符串或cookie放在URL中。然后将您的页面重定向到另一个页面，从查询字符串或cookie中获取日期值，然后将其分配给会话缓存。
What you are doing won't work because yourfulldatevariable is initialized client side but Session ["CDATE"] is assigned server side.
Create a page that places your fulldate either in the url as a query string or in a cookie. Then redirect your page to another that gets the date value from the query string or cookie and then assign it to the session cache.
< %%>符号可用于将服务器端代码嵌入到最终呈现的客户端页面中。
它无法在周围工作，因为< %%>的内容仍然在服务器上解析。
如果你想从客户端获得客户端的时间（时区），你只能在回发后才能这样做。阅读本文： http://www.prideparrot.com/blog/archive/2011/9/how_to_display_dates_and_times_in_clients_timezone [ ^ ]
另一种选择是使用某些第三方调查IP并决定什么时区客户端属于...
The <% %> notation can be used to embed server side code into the final rendered client side page.
It can not be work on the way around, as the content of <% %> parsed while still on the server.
If you want to get the client's time (time-zone) from the client you can do it only after postback. Read this article: http://www.prideparrot.com/blog/archive/2011/9/how_to_display_dates_and_times_in_clients_timezone[^]
An other option is to use some 3rd party to investigate the IP and decide to what timezone client belongs...
您可以在客户端读取会话的值但是无法在客户端初始化/写入会话，因为它是服务器对象。请使用 HiddenField 保存客户端系统的日期，如下例所示。
You can read the value of session at client side but can't initialized/write session at client side as it is a server object. Please use HiddenField to save the date of client system as shown below in example.
// Write this javascript code on <Head> tag of page and call it on window's load.
<script type="text/javascript">
window.onload = function () {
var currentTime = new Date();
var fulldate = currentTime.getFullYear()
// here converting the month number into integer and then adding 1 to it.
+ '-' + (parseInt(currentTime.getMonth()) + 1)
+ '-' + currentTime.getDate()
+ ' ' + currentTime.getHours()
+ ':' + currentTime.getMinutes()
+ ':' + currentTime.getSeconds()
+ ':' + currentTime.getMilliseconds();
// Save date in hidden field..
document.getElementById('<%=hdnDate.ClientID%>').value = fulldate;
}
I hope this solution will help you.. :)
</script>
//< Body>中的控件声明页面标签..
// Declaration of controls in <Body> tag of page..
<asp:hiddenfield id="hdnDate" runat="server" xmlns:asp="#unknown" />
<br />
<br />
<asp:button id="btnGetDate" runat="server" text="Button" onclick="btnGetDate_Click" xmlns:asp="#unknown" />
// On按钮单击，您可以在隐藏字段的帮助下访问服务器端的客户端日期..
// On Button Click, You can access client date at server side with help of hidden field..
protected void btnGetDate_Click(object sender, EventArgs e)
{
Response.Write(hdnDate.Value);
}
