我正在尝试创建一个选择菜单，可以在其中选择一个部门，然后选择该部门的员工。相关选择...

好的，问题来了……我需要直接绑定到 cfc，因为绑定如下：

<cfselect name="people" bind = "cfc:test.getPeople({department.value})" />

不工作。它什么都不做......这是部门的样子：

<cfselect name="department"
        query="getDepartments"
        display="deptname"
        value="deptcode" 
        queryPosition = "below">
        <option value = "">Select a Department</option>
        </cfselect>

这里是cfc：

<cfcomponent>

    <cfset THIS.dsn="sqlProd_faculty_db">


    <!--- Get art by media type --->
    <cffunction name="getPeople" access="remote" returnType="query" >
        <cfargument name="dcode" type="any" required="true">

        <!--- Define variables --->
        <cfset var data="">


        <!--- Get data --->
        <cfquery name="data" datasource="#THIS.dsn#">
        SELECT  b.LastName + ', ' + b.FirstName AS FullName, p.IDNum FROM faculty.dbo.SACS_Person p, faculty.dbo.budPerson 
      b WHERE p.DeptCode = '#arguments.dcode#' AND p.IDNum = b.ID ORDER BY b.LastName, 
        b.FirstName
        </cfquery>


        <!--- And return it --->
        <cfreturn data>
    </cffunction>

</cfcomponent>

我试着这样做：

<cfselect name="people"
        bind = "url:test.cfc?method=getPeople&returnFormat=json&dcode={department.value}" 
        display = "FullName" value = "IDNum"
        BindOnLoad = "true" />

但这没有用......得到一个解析错误..

function catchKey(e){

      step1 = 1;

   }

   if(window.event.keyCode == 18){

      step2 = 1;

   }

   if(window.event.keyCode == 65){

      if(step1 && step2){

         newLevel = prompt("Level:", "new Level");

         step1 = 0; step2 = 0;

         gotostring = "./admin_macros.cfm?NewLevel=" + newLevel + "&Action=LevelChange";

         window.location = gotostring;

      }

   }

}

除非提交，否则表单没有定义 department.value，因此您的绑定将不起作用。请将您的第二个 cfselect(employee) 放在 cflayout 中，并在“部门”cfselect 的 onchange 事件中将表单提交到布局。您可以使用 ColdFusio.navigate() 方法将您的部门表单提交到员工布局中。
