我不知道这是否会帮助，但我的工作与angularjs数据的工作，并期待在这个帖子：会谈上使用CFC的瓦特/输出需要创建自己的JSON（还演示了如何CFMX处理JSON调用）有点

  

在ColdFusion MX的一个名为CFC直接返回WDDX。要制止这种，直接输出而不是[使用] cfreturn和追加cfabort即：

 ＆LT; cfcontent复位=YES/＆GT;＆LT; CFOUTPUT＆GT; #Trim（EN code（qryExample））＃＆LT; / CFOUTPUT＆GT;＆LT; cfabort /＆GT ;
 

My cfc is working because I can invoke it and get the json string of data, however, my jquery ajax call gives me an error "SyntaxError: JSON.parse: unexpected end of data".

ajax call:

$.ajax({
    type: "get",
    url: "/surveymanagement/admin/client.cfc",
    dataType: "json",
    data: {
        method: "GetClientsByName",
        name: "im"
    },
    success: function(data){
        $("#here").html(data);
    },
    error: function(a,b,c){
        $("#here").html(a.responseText + c);
    }
});

When I invoke the component in another cfm page my cfc returns the string: [{"client_id":58,"client_name":"Aimbridge"},{"client_id":104,"client_name":"IMF"}] .

What might my problem be?

also, if I go directly to my cfc in the browser http://domain.com/filepath/client.cfc?method=GetClientsByName&name=imI don't get errors but it is just a white screen. I don't know what I am supposed to be seeing when I go directly to it.

for the sake of all info here is client.cfc:

<cfcomponent>
<cfsetting showdebugoutput="no">
<cffunction name="GetClientsByName"
    access="remote"
    returntype="string" 
    hint="get clients from search term">

    <cfargument name="name" type="string" required="yes">

    <cfset var util = createObject("component", "/surveymanagement/JSONUtil")>
    <cfset var results = arrayNew(1)>
    <cfset var elem = "">

    <cfquery name="GetClientsByName" datasource="#application.dsn#">
        SELECT client_id, client_name
        FROM Clients
        WHERE client_name LIKE <cfqueryparam cfsqltype="cf_sql_varchar" value="%#arguments.name#%">
    </cfquery>

    <cfloop query="GetClientsByName">
        <cfset elem = structNew()>
        <cfset elem["client_id"] = GetClientsByName.client_id>
        <cfset elem["client_name"] = GetClientsByName.client_name>
        <cfset arrayAppend(results, elem)>
    </cfloop>

    <cfcontent type="application/json" reset="true">
    <cfreturn util.serializeJSON(results)>
</cffunction>
</cfcomponent>

Note: I'm using coldfusion7 so I cannot use returnformat='json'

application.cfc maybe something went awry here:

I'm not sure if this will help but I'm working on working with data for angularjs and was looking at this post: Talks a bit on using CFC's w/out the need to create the JSON yourself (also demonstrates how CFMX handled json calls).

In ColdFusion MX a cfc called directly returned wddx. To stop this, output directly instead of [using] cfreturn and append cfabort ie:

<cfcontent reset="yes" /><cfoutput>#Trim(encode(qryExample))#</cfoutput><cfabort />
