Question

我正在尝试创建一个包含3个选择框的表单，这些框绑定到cfc（三重相关的cfselect）。如果我删除了Application.cfc，代码运行得很好，选择框会提供我需要的数据。但是，当我添加具有cflogin功能的Application.cfc时，该功能要求用户在能够使用任何页面之前登录，而不是我的三重相关选择框不再起作用。选择框只是不会从函数中的查询中提供任何数据。它仍然连接到函数页面，因为当我在cfselect的绑定上更改名称时，它会让我知道组件中不存在该函数。我不知道我需要做些什么来使三重相关的cfselect与cflogin一起使用。
我正在使用ColdFusion 10 我非常感谢任何建议。
谢谢，Niva

我添加了代码：这是表单上的代码

<tr valign="top">  
    <td style="color:DarkSeaGreen; font-weight:bold; width=100">Product Type:</td>
    <td width="200">
    <cfselect name="Selproducttype" bind="cfc:groupfnc.getproducttypeid()"
        display="description" value="producttypeid" BindOnLoad="true"/></td></tr>
<tr valign="top">  
    <td style="color:DarkSeaGreen; font-weight:bold; width=100">Vendor:</td>
    <td width="200">
    <cfselect name="Selvendor" bind="cfc:groupfnc.getven({Selproducttype})"
        display="fullname" value="vendorid" BindOnLoad="true"/></td></tr>   

<tr valign="top">  
    <td style="color:DarkSeaGreen; font-weight:bold; width=100">Product:</td>
    <td width="200">

<cfselect name="Selprod" bind="cfc:groupfnc.getprod({Selvendor})"
        display="fullname" value="productid" BindOnLoad="true" /></td></tr>
<tr valign="top">  
    <td style="color:DarkSeaGreen; font-weight:bold; width=100">Sub Product:</td>
    <td width="200">
    <cfselect name="Selsubprod" bind="cfc:groupfnc.Getsub({Selprod})"
        display="fullname" value="productsubid" /></td></tr>

组件代码：groupfnc.cfc

  <cffunction name="getproducttypeid" access="remote" output="false" returntype="query">
<cfquery name="listproducttype" datasource="xxxxxx">
    Select distinct producttypeid, (Case when producttypeid = '101' then 'Hotel' 
                         when producttypeid='201' then 'optionalTour' 
                         when producttypeid = '301' then 'Transporation' 
                         when producttypeid = '501' then 'MISC'
                         when producttypeid = '601' then 'OTH' end) as description
    From products
</cfquery>
<cfreturn listproducttype />
</cffunction>

<cffunction name="getven" access="remote" output="false" returntype="Query">

    <cfif ARGUMENTS.Selproducttype EQ "">
    <cfset ARGUMENTS.Selproducttype = '0'>
    </cfif>
    <cfquery name="listven" datasource="xxxxxx">
    SELECT distinct vendors.fullname, vendors.vendorid 
    from vendors, products
    where products.vendorid= vendors.vendorid
    and  products.producttypeid = #ARGUMENTS.Selproducttype#
    ORDER BY fullname
    </cfquery>
    <cfreturn listven />
</cffunction>


<cffunction name="getprod" access="remote" output="false" returntype="Query">
    <cfargument name="Selvendor" type="any" required="true">

    </cfif>
    <cfquery name="Lstprod" datasource="xxxxxx">
    Select productid, fullname from products
    where vendorid = #ARGUMENTS.Selvendor#
    order by fullname
    </cfquery>
    <!---</cfif>--->
    <cfreturn Lstprod />
</cffunction>    
<cffunction name="Getsub" access="remote" output="false" returntype="Query">
    <cfargument name="Selprod" type="any" required="true">

    order by fullname
    </cfquery>
    <!---</cfif>--->
    <cfreturn Lstsubprod />
</cffunction>

这是我的application.cfc

  <cfcomponent> 
   <cfset This.name = "Orders"> 
   <cfset This.Sessionmanagement="True"> 
   <cfset This.loginstorage="session"> 

     <cffunction name="OnRequestStart"> 

       <cfargument name = "request" required="true"/> 
         <cfif IsDefined("Form.logout")> 
          <cflogout> 
        </cfif> 

    <cflogin> 
       <cfif NOT IsDefined("cflogin")> 
         <cfinclude template="loginform.cfm">

          <cfabort> 
       <cfelse> 
        <cfif cflogin.name IS "" OR cflogin.password IS ""> 

            <cfoutput> 
                <h2>You must enter text in both the User Name and Password fields. 
                </h2>

Answer 1

我发现了问题。因为在我的Application.cfc中有这个部分：

        <form action="securitytest.cfm" method="Post"> 
        <input type="submit" Name="Logout" value="Logout"> 
    </form> 

   </cfoutput>

所以看一下ajax响应，logout表单被放置了infornt，所以select框没有解析这个值。我在Application.cfc中删除了这个部分，页面运行得很好。非常感谢您的帮助！ ^ _ ^

启用Application.cfc时，cfc中的cfselect bind不起作用
