如何在我的asp页面中的'OnClick'事件中传递脚本中的参数？(How can pass a parameter in script on 'OnClick'

如何在我的asp页面中的'OnClick'事件中传递脚本中的参数？(How can pass a parameter in script on 'OnClick' event in my asp page?)

我需要在我的脚本子中传递一个参数，我在asp页面上尝试这个：

<asp:LinkButton ID="LinSoftWares" OnClick="ProductChange(product)" runat="server" >Softwares</asp:LinkButton>

这个脚本：

    <script runat="server">
        Sub ProductChange(ByVal StrCommand As String)
            If StrCommand = "product" Then
                If Session("BlnProductShow") = 1 Then
                    Session("BlnProductShow") = 0
                Else
                    Session("BlnProductShow") = 1
                End If
                DoRefresh()
            End If

        End Sub

        Sub DoRefresh()
            If Session("BlnProductShow") = 1 Then
                DivProduct.Style.Value = "visibility: visible"
            Else
                DivProduct.Style.Value = "visibility: hidden"
            End If

        End Sub

    </script> 
  
 
 
 但我得到了这个错误： 
 
 '产品'未申报。 由于其保护级别，它可能无法访问 
I need to pass a parameter in my script sub, i try this on asp page :
 
<asp:LinkButton ID="LinSoftWares" OnClick="ProductChange(product)"  runat="server" >Softwares</asp:LinkButton>
 
and this for script :
 
 
 
  
  
    <script runat="server">
        Sub ProductChange(ByVal StrCommand As String)
            If StrCommand = "product" Then
                If Session("BlnProductShow") = 1 Then
                    Session("BlnProductShow") = 0
                Else
                    Session("BlnProductShow") = 1
                End If
                DoRefresh()
            End If

        End Sub

        Sub DoRefresh()
            If Session("BlnProductShow") = 1 Then
                DivProduct.Style.Value = "visibility: visible"
            Else
                DivProduct.Style.Value = "visibility: hidden"
            End If

        End Sub

    </script> 
  
 
 
But i got this error :
 
'product' is not declared. It may be inaccessible due to its protection level

 我在VB.Net没有太多经验，但是在C#我会按照以下方式进行操作，添加CommandArgument属性并为其分配默认值，然后在其单击中我将得到该值。 
 
 ASPX： 
 
<asp:LinkButton ID="LinSoftWares" 
                runat="server" 
                CommandArgument="Product" 
                OnClick="LinSoftWares_Click" > 
Softwares
</asp:LinkButton>
 
 C＃ 
 
protected void LinSoftWares_Click(object sender, EventArgs e)
{
    LinkButton lnkSender= (LinkButton)(sender);
    string value = lnkSender.CommandArgument;
    // do what you need here
}  
 
 编辑： 
 
 如果您的参数“product”是动态的，那么如果您的控件在某些数据绑定控件中，则可以使用Eval("Product") 。 
I don't have much experience in VB.Net but in C# I would do in following way, add CommandArgument property and assign it with a default value and then in its on click I would get the value.
 
Aspx:
 
<asp:LinkButton ID="LinSoftWares" 
                runat="server" 
                CommandArgument="Product" 
                OnClick="LinSoftWares_Click" > 
Softwares
</asp:LinkButton>
 
C#
 
protected void LinSoftWares_Click(object sender, EventArgs e)
{
    LinkButton lnkSender= (LinkButton)(sender);
    string value = lnkSender.CommandArgument;
    // do what you need here
}  
 
Edit:
 
In case your argument "product" is dynamic then you can use Eval("Product") if your control is in some data binder control.
