如何将控制从javascript传递到asp.net中的codebehind

嗨


以下是我的代码。我正在接受一个文件上载控件，即

Hi
below is my code. I am taking one fileupload control i.e.,

<asp:FileUpload ID="FileUpload1" runat="server" onchange="Showpath(this)" />

和我的javascript代码是：

and my javascript code is:

function Showpath(e) {
         var file;
         file = e;
         PageMethods.SaveImage("how to pass fileupload control here");
         }

我写了一个函数，即

in my .vb page i write one function i.e.,

<System.Web.Services.WebMethod()> _
    Public Shared Function SaveImage(ByVal fUpload As fileupload) As String

    Return ""

    End Function

i希望在此方法中传递fileupload1控件PageMethods.SaveImage..

我该怎么办？



谢谢
