    ====================================================================
    获取当前Url参数的函数

    ====================================================================
    Private Function GetUrl(RemoveList)
        Dim ScriptAddress, M_ItemUrl, M_item
        ScriptAddress = CStr(Request.ServerVariables("SCRIPT_NAME"))&"?"取得当前地址

    =============================
    实现列表排序
    返回Url参数并动态改变排序方式
    参数：需要进行排序的字段名,显示的名称
    =============================

    -----------------------------------------------
    标识排序列为升序还是降序方式
    参数：排序列字段名称
