Question

我找到并使用了Ben Forta's nice tutorial for related selects。在第一个选择中，用户选择一个物种。在第二个选择中填充了化学品清单。第二个选择是多选。

我现在正在尝试使用Chosen jQuery plugin。它在我尝试过的其他选项上运行良好，但是当我尝试使用相关选项时，它无效。有可能绑定的东西吗？

Select Species:
    <cfform name="mainform" method="Post" action="organism.cfm">
    <cfselect name="SpeciesID" class="chosen-select"
         bind="cfc:species.getSpecies()" bindonload="true"></cfselect>
<script type="text/javascript" charset="utf8" src="chosen.jquery.js">
</script>
<script>
    $(document).ready(function() {
    $('cfselect').chosen()});
</script>

Select a chemical:
    <cfselect name="AnalyteID" multiple="yes" required="Yes" size="5"    
        class="chosen-select" message="Please choose a chemical" 
        bind="cfc:species.getChemName({SpeciesID})" 
   </cfselect>

CFC

<cfcomponent output="false">

<cfset THIS.dsn="MyDatabase">

<!--- Get array of species --->
<cffunction name="getSpecies" access="remote" returnType="array">
    <!--- Define variables --->
    <cfset var data="">
    <cfset var result=ArrayNew(2)>
    <cfset var i=0>

    <!--- Get genus species data --->
    <cfquery name="data" datasource="#THIS.dsn#">
    SELECT DISTINCT SpeciesID, GenusSpecies
    FROM Table1
    ORDER BY GenusSpecies
    </cfquery>

    <!--- Convert results to array --->
    <cfloop index="i" from="1" to="#data.RecordCount#">
        <cfset result[i][1]=data.SpeciesID[i]>
        <cfset result[i][2]=data.GenusSpecies[i]>
    </cfloop>

    <cfreturn result>
</cffunction>

<!--- Get analyte sorted by genus species --->
<cffunction name="getChemName" access="remote" returnType="array">
<cfargument name="SpeciesID" type="numeric" required="true">

    <!--- Define variables --->
    <cfset var data="">
    <cfset var result=ArrayNew(2)>
    <cfset var i=0>

    <!--- Get analytes --->
    <cfquery name="data" datasource="#THIS.dsn#">
    SELECT DISTINCT analyteID, ChemName
    FROM Table2
    WHERE SpeciesID = #ARGUMENTS.SpeciesID#
    ORDER BY ChemName
    </cfquery>

    <!--- Convert results to array --->
    <cfloop index="i" from="1" to="#data.RecordCount#">
        <cfset result[i][1]=data.analyteID[i]>
        <cfset result[i][2]=data.ChemName[i]>
    </cfloop>

    <cfreturn result>
</cffunction>
</cfcomponent>

也许另一个插件可以更好地满足我的需求。任何建议都会有所帮助。
