Question

我正在努力创建一个自动提示，但是在为JQUERY插件正确显示数据时遇到了问题。

我的桌子上摆满了customers(customerID,fName,lName)

我需要像这样创建一个JSON响应：

[{"id":"856","name":"House"},
 {"id":"1035","name":"Desperate Housewives"},
 {"id":"1048","name":"Dollhouse"},
 {"id":"1113","name":"Full House"}
]

现在我在Coldfusion中的代码看起来像这样：

Query - sel_Customers.cfm

<cfset newAjax.setJSONStructKey(key="id", value="#sel_Customers.customerID#")>
<cfset newAjax.setJSONStructKey(key="name", value="#sel_Customers.fName#")>

这导致回复：

[{"returnmessage":"The Ajax operation was successful.","name":"Howard","id":"1","returncode":"0"}]

哪个只显示1个记录而不是3.在Coldfusion中是否有办法设置JSONStructKey，如上所示并粘贴？

我不确定你的setJSONStructKey到底是什么，但是假设你需要结构数组。

硬编码示例：

<cfset json = [] />

<cfset customer = {} />
<cfset customer["id"] = "856" />
<cfset customer["name"] = "House" />
<cfset ArrayAppend(json, customer) />

<cfset customer = {} />
<cfset customer["id"] = "1035" />
<cfset customer["name"] = "Desperate Housewives" />
<cfset ArrayAppend(json, customer) />

<cfoutput>
#SerializeJSON(json)#
</cfoutput>

因此输出如下：

[{"id":856.0,"name":"House"},{"id":1035.0,"name":"Desperate Housewives"}]

使用cfloop：

<cfset json = [] />

<cfloop query="sel_Customers">
    <cfset customer = {} />
    <cfset customer["id"] = sel_Customers.customerID />
    <cfset customer["name"] = sel_Customers.fName />
    <cfset ArrayAppend(json, customer) />
</cfloop>

<cfoutput>
#SerializeJSON(json)#
</cfoutput>

注意：请注意this floating numbers issue与SerializeJSON。

AJAX，setJSONStructKey多组数据的问题
