将值从后端代码传递到Javascript时的变量命名

我正在将doctype变量的值从我的c#代码传递给javascript

现在我无法根据输入找到任何文件

命名约定必须准确吗

编辑：在

onclick

javascript页面中添加了带有

DocType

硬编码的当前版本

---

变量： ascx.cs中的文件类型

ascx中的

DocType

AllGroup\u UserControl.ascx.cs:

public partial class AllGroup_UserControl : UserControl
{
    ProductProvider provider = new ProductProvider();
    TBL_USER_PROFILEProvider uprovider = new TBL_USER_PROFILEProvider();
    DocumentProvider dprovider = new DocumentProvider();

    int DOC_TYPE;
    // Document Types
    const int G1_DOC_TYPE = 1;
    const int G2_DOC_TYPE = 2;
    const int G3_DOC_TYPE = 3;

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string userName = SPContext.Current.Web.CurrentUser.Name;
            TBL_USER_PROFILE p = uprovider.GetUser(userName);
            if (p != null)
            {
                List<string> G1List = uprovider.GetAccessByModuleName(p.UserProfileID, "Group 1");
                List<string> G2List = uprovider.GetAccessByModuleName(p.UserProfileID, "Group 2");
                List<string> G3List = uprovider.GetAccessByModuleName(p.UserProfileID, "Group 3");

                if (G1List.Count != 0)
                {
                    DOC_TYPE = G1_DOC_TYPE;
                }
                else if (G2List.Count != 0)
                {
                    DOC_TYPE = G2_DOC_TYPE;
                }
                else if (G3List.Count != 0)
                {
                    DOC_TYPE = G3_DOC_TYPE;
                }
                else
                {
                    Response.Redirect("/SitePages/AccessDeny.aspx");
                }

                Page.DataBind();
            }
        }
    }

    public int DocType
    {
        get
        {
            return DOC_TYPE;
        }
    }

//rest of the code

<a href="#" runat="server" onclick="openDialog('/SitePages/FileDownload.aspx?DocType=<%# DocType %>&ItemNo=<%#Eval("StoreItemNo")%>&CustomerID=<%#Eval("CustomerID")%>')">

Group1\u UserControl.ascx：（doctype硬编码）

为此，您必须使用AJAX。然后可以将值从后端传递到JavaScript。 下面是一个例子

客户端脚本

您能否从

ascx.cs

和

UserControl.ascx.cs:

更新了我的

ascx.cs

类文件@D-Shihi不确定此链接是在哪里生成的，因为您使用

无法根据输入找到任何文件-您能解释页面数据绑定事件发生了什么吗？另外，在
onclick
部分中究竟生成了什么样的URL？在答案中添加示例比单独发布链接更有用谢谢Abana，我将用一个示例更新我的答案
public partial class Group1_UserControl : UserControl

    ProductProvider provider = new ProductProvider();
    TBL_USER_PROFILEProvider uprovider = TBL_USER_PROFILEProvider();
    DocumentProvider dprovider = new DocumentProvider();
