JavaScript-如何在JavaScript中为会话设置值 [英] JavaScript - How to Set values to Session in Javascript

问题描述

我想在会话中设置下拉列表选择的值.我已经在后面的代码中做了.但是对于某些情况，我必须自己在客户端执行.我尝试了以下.但是我还没有解决办法.

Hi,
I want to set the Dropdown selected value in Session. I have done in Code behind. But for some condition i have to Do in Client Side Itself. i tried the following. but i did''t solution yet.

<%Session["Test"] = "Welcome Mamu";%>
var session_value='<%=Session["Test"]%>'; 
alert(session_value); 

以上工作正常.请注意，我已分配了静态值(欢迎使用Mamu).但对于Dynamatic，

The above work fine. Note that i have assign Static value(Welcome Mamu). but for Dynamatic,

var strTest=document.getElementById('DropDownList1').value; 
<%Session["Test"] = "'+ strTest +'";%> 
var session_value='<%=Session["Test"]%>';
alert(session_value); 

在客户端运行正常.但是在服务器端(后台代码)中，Session ["Test"]的值为''+ strTest +''.

It is Working fine in Client Side. But i Server Side(Code Behind), the Session["Test"] value is ''+ strTest +''.

Is any other way to assign values to Session?

推荐答案

无法直接通过javascript直接分配会话值.

我找到了其他方法.调用函数背后的代码并分配会话值.

Javascript函数:

Not possible to assign session values directly through javascript.

I found alternative ways. Call the code behind function and assign the session values.

Javascript Function:

 function InitializeRequest(path) {
            // call server side method
            PageMethods.SetDownloadPath(path);
}

函数背后的代码:

[System.Web.Services.WebMethod]
    public static string SetDownloadPath(string strpath)
    {
        Page objp = new Page();
        objp.Session["strDwnPath"] = strpath; 
        return strpath;
    }

必须将页面方法设置为true

<asp:ScriptManager EnablePageMethods="true" ID="MainSM" runat="server" ScriptMode="Release" LoadScriptsBeforeUI="true"></asp:ScriptManager>

function setJavascript() {
       <% var text1= "Welcome Mamu";%>
           <%Session["status"] =text1;%>
var session_value='<%=Session["status"]%>';
alert(session_value);
        return false;
        }

而不是使用Session["Test"]= ''+ strTest +''.;
使用此Session["Test"]=strTest ;，因为它是直接访问的cs页面的成员.

Instead of using Session["Test"]= ''+ strTest +''.;
use this one Session["Test"]=strTest ; because it is member of cs page it directly accessed.
