In VC# code, it gets the current date time from system

protected System.DateTime CurDateTime;

protected string SysDateTime;

this.CurDateTime = System.DateTime.Now;

this.SysDateTime = this.CurDateTime.ToString("month dd, yyyy HH:mm:ss");

I have a javascript variable needs to get the SysDateTime value in aspx page.

var currenttime = <%= SysDateTime %>;

But, it cannot get it, how should I write it?

Instead of: var currenttime = <%= SysDateTime %>;

Try: var currenttime = "<%= SysDateTime %>";

I would put the javascript in the codebehind and then build it that way. Then when the page is built server side, the script is generated and sent clientside ready populated. Take a look at http://msdn.microsoft.com/en-us/library/system.web.ui.page.registerstartupscript(VS.71).aspx

Page.RegisterStartupScript and Page.RegisterClientScriptBlock both emit javascript to the client side but are built server side which means you have full control over it.
