ASP.NET下根据QueryString决定使用哪块&#106avascript的两种方法 :)

在asp下,有时候会使用下面的代码:

<%
if request("m") = "1" then%>
<script language="javascript">
<!--
m_name[0] = "《财经》杂志 ";
//m_period[0] = 6;
init(1, 1, 1);
//-->
</script>
<%
else%>
<script language="javascript">
<!--
m_name[0] = "《财经》杂志 ";
init(0, 1, 1);
//-->
</script>
<%end if%>
<%if request("m") = "2" then%>
<script language="javascript">
<!--
m_name[1] = "《证券市场》周刊(综合刊)";
m_name[2] = "《证券市场》周刊(市场刊)";
init(1, 2, 1);
init(1, 3, 1);
//-->
</script>
<%
else%>
<script language="javascript">
<!--
m_name[1] = "《证券市场》周刊(综合刊)";
m_name[2] = "《证券市场》周刊(市场刊)";
init(0, 2, 1);
init(0, 3, 1);
//-->
</script>
<%end if%>

如果是在asp.net下,如何解决呢?

方法1(使用viewstate):(蒙斑竹鸿雪指教,试验成功)

<script language="javascript">
            <!--
            
            function howmuch2view(iselect, iview)
            {
                var m1, m2;
                switch(iselect)
                {
                    case 1:
                        m1 = 1;
                        m2 = 0;
                        break;
                    case 2:
                        m1 = 0;
                        m2 = 1;
                        break;
                    default:
                        m1 = 1;
                        m2 = 0;
                        break;
                
                }
                                
                switch(iview)
                    {
                    case 1:
                        m_name[0] = "《财经》杂志 ";
                        //m_period[0] = 6;
                        init(m1, 1, 1);                
                        break;
                    case 3:
                        m_name[0] = "《财经》杂志 ";
                        //m_period[0] = 6;
                        init(m1, 1, 1);
                        
                        m_name[1] = "《证券市场》周刊(综合刊)";
                        m_name[2] = "《证券市场》周刊(市场刊)";
                        init(m2, 2, 1);
                        init(m2, 3, 1);
                    
                        break;
                    default:
                        m_name[0] = "《财经》杂志 ";
                        //m_period[0] = 6;
                        init(m1, 1, 1);                
                        break;
                    break;
                    }
            }
            
            howmuch2view(<%=viewstate["which2select"]%>,<%=viewstate["howmuch2view"]%>);
            
            
            //-->
                                                </script>
------------------------------------
方法2(使用panel的visible属性):
webform:
<asp:panel id="pnljsinitm1" runat="server" visible="false">
                            <script language="javascript">
    <!--
    m_name[0] = "《财经》杂志 ";
    //m_period[0] = 6;
    init(1, 1, 1);
    //-->
                            </script>
</asp:panel>

<asp:panel id="pnljsinitm1n" runat="server" visible="false">
                        <script language="javascript">
    <!--
    m_name[0] = "《财经》杂志 ";
    //m_period[0] = 6;
    init(0, 1, 1);
    //-->
    </script>
</asp:panel>

<asp:panel id="pnljsinitm2" runat="server" visible="false">
                            <script language="javascript">
    <!--
    m_name[1] = "《证券市场》周刊(综合刊)";
    m_name[2] = "《证券市场》周刊(市场刊)";
    init(1, 2, 1);
    init(1, 3, 1);
    //-->
    </script>
</asp:panel>

<asp:panel id="pnljsinitm2n" runat="server" visible="false">
                            <script language="javascript">
    <!--
    m_name[1] = "《证券市场》周刊(综合刊)";
    m_name[2] = "《证券市场》周刊(市场刊)";
    init(0, 2, 1);
    init(0, 3, 1);
    //-->
                        </script>
</asp:panel>
-----------------------------------------------

codebehind:

string strm;
            try
            {
                strm = request.querystring["m"].trim();
            }
            catch
            {
                strm = "3";
            }


    switch(strm)
    {
    case "1":
                    pnljsinitm1.visible = true;
                    pnljsinitm1n.visible = false;
                    pnljsinitm2.visible = false;
                    //pnljsinitm2n.visible = true;
                    pnljsinitm2n.visible = false;
    break;

    case "2":
                    pnljsinitm1.visible = false;
                    pnljsinitm1n.visible = true;
                    pnljsinitm2.visible = true;
                    pnljsinitm2.visible = false;
                    //pnljsinitm2n.visible = false;
    break;

    default :
                    pnljsinitm1.visible = false;
                    pnljsinitm1n.visible = true;
                    pnljsinitm2.visible = false;
                    //pnljsinitm2n.visible = true;
                    pnljsinitm2n.visible = false;
    break;

    }
