Question

我试图通过ajax返回一个struct数组来提供自动完成功能。我想从我要填充文本框的页面中通过ajax调用 getEmployeeName 。

test.cfc如下：

<cfcomponent>
<cffunction name="getEmployeeName" access="remote" returnformat="JSON" >
    <cfargument name="term" type="string" required="yes">

    <cfset var returnArray=ArrayNew(1) />
    <cfset term=#Ucase(term)#>
    <cfquery name="getEmps" datasource="mines">
        ...
        <!--- my query ---!>
    </cfquery>

    <cfoutput>
    <cfloop query="getEmps">
        <cfset empStruct = StructNew() />
        <cfset empStruct["label"] = #emp_name# & " " &#desg_desc# & " " & #unit_name# />
        <cfset empStruct["value"] = #cpf_no#>

        <cfset ArrayAppend(returnArray,empStruct) />
    </cfloop>
    </cfoutput>
    <cfreturn #serializeJSON(returnArray)#>
</cffunction>

ajax调用如下：

$("#task_coordinator").autocomplete({
            source: function (request, response) {
                     $.ajax({
                             url: "test.cfc?method=getEmployeeName",
                             type: "GET",
                             data: request,
                             success: function (data) {



                                    console.log(data);
                                    console.log(data.array([label]));

                             },
                             error: function(jqXHR, extStatus,errorThrown){
                                alert(errorThrown);
                             }
                     });
            },
            select: function (event, ui) {

            }
            ,minLength:5
    });

我尝试直接通过链接调用该方法，看看它是否正常工作。在那时它只返回json数据而不是这些额外的信息。我的输出在json数据之前有额外的脚本：

        _CF_error_fields = new Object();
        _CF_FirstErrorField = null;


        //display error messages and return success
        if( _CF_error_exists )
        {
           if( _CF_error_messages.length > 0 )
           {
                // show alert() message
                _CF_onErrorAlert(_CF_error_messages);
                // set focus to first form error, if the field supports js focus().
                if( _CF_this[_CF_FirstErrorField].type == "text" )
                { _CF_this[_CF_FirstErrorField].focus(); }

            }
            return false;
        }else {
            return true;
        }
    }
//-->
</script>
[{"value":47455,"label":"BANTHIA ANUJA RAVINDRAKUMAR GRADUATE EXECUTIVE TRAINEE(E2) CENTRAL ESTABLISHMENT"}]

有人可以告诉我为什么这个额外的剧本即将到来。提前谢谢！

在ColdFusion Administrator中，选择Debugging＆amp;记录＆gt;调试器设置。你应该在那里找到一些设置来帮助调试AJAX请求。如果选中它，请尝试将其关闭。
