会话价值不会显示 [英] Session Value wont show up

问题描述

大家好，

我在文本框中显示会话值时遇到问题.

这是我的代码:

在我的页面加载中:

Hello guys,

I have problem about displaying Session value in textbox.

Here is my code:

Inside my page load:

string msgBoxVal = string.Empty;
if (Session["LabelDetails"] != null)
{
  msgBoxVal = (String)Session["LabelDetails"];
  Session.Remove("LabelDetails");
}
if (msgBoxVal != "")
{
  MessageBox("Test1");
  MessageBox("The shipping label is successfully deleted! Deleted label details: " + msgBoxVal);
  MessageBox("Test2");
}

和我的MessageBox代码:

and my code for MessageBox:

private void MessageBox(string msg)
{
  Page.Controls.Add(new LiteralControl("<script language='javascript'> window.alert('" + msg.Replace("'", "\\'") + "')</script>"));
}

这让我发疯，因为我有两个显示为Test1和Test2的警报框，但是其中一个我想显示的警报框却没有出现.

我已经仔细检查了Session是否不为null，并且该值已分配给msgBoxVal，并且在调试模式下它不会引发异常.有人可以告诉我我哪里错了吗?

谢谢.

This drives me crazy because I am having two alertbox show as Test1 and Test2 but one which is in the middle that I want to show won''t appear.

I have double checked that Session is not null and the value gets assigned to msgBoxVal and during the debug mode it doesnt throw an exception. Can someone tell me where I am wrong?

Thanks.

推荐答案

您好尝试了您的代码并更改了一些简单的小东西，然后我测试了结果
试试这个

hi tried your code and changed simple small things and i tested the results
try this

protected void Page_Load(object sender, EventArgs e)
   {
       //the line was just to test it
      //Session.Add("LabelDetails", 454);
       string msgBoxVal = string.Empty;
       if (Session["LabelDetails"] != null)
       {
           msgBoxVal = Convert.ToString(Session["LabelDetails"]);
           Session.Remove("LabelDetails");
       }
       if (msgBoxVal != "")
       {
           MessageBox("Test1");
           MessageBox("The shipping label is successfully deleted! Deleted label details: " + msgBoxVal);
           MessageBox("Test2");
       }


   }

   private void MessageBox(string msg)
   {
       Page.Controls.Add(new LiteralControl("<script type=\"text/javascript\"> window.alert('" + msg.Replace("'", "\\'") + "')</script>"));
   }

这是冗长的编码.您可以直接访问javascript中的 Session
看到这个

This is the lengthy coding. either you directly access Session in javascript
see this

var Labeldet;
Labeldet = = <%=Session("LabelDetails")%>;
