使用 AJAX 调用带有多个参数的 CFC

Question

我正在使用 AJAX 调用 CFC，我正试图从我运行的查询中发送两个变量。我的 ajax 看起来像这样：

    $.ajax({
     type:"POST",
     url:"cfcs/get_equipment_details.cfc?method=getDetails",
     dataType: 'json',
     data: { equipment_name: "#equipment_name#", customer_name: "#customer_name#"},
    cache:false,
    success: function(response) {
        console.log("Customer Name" + customer_name);

        $.each(response.DATA, function(i, row){
            var id = row[0];
            var customer_name = row[1];
            var equipment_name = row[2];
            var date_last_completed = row[3];
            var maintenance_interval = row[4];
            var last_completed_by = row[5];
            var equipment_notes = row[6];
            var warranty_end_date = row[7];
            var service_Tag = row[8];
            var serial_number = row[9];
            var backup_notes = row[10];
            var TT = row[11];
            $("##customer_name#id#").val(customer_name);
            });
     }
});

这是我的 CFC：

<cffunction name="getDetails" access="remote" output="false" returntype="query">
    <cfargument name="equipment_name" type="any" required="true">
    <cfargument name="customer_name" type="any" required="true">

    <!--- Get list of all equipment --->    
    <cfquery name="get_equipment" datasource="#datasource#">
    select *
    from equipment_maintenance
    where equipment_name= <cfqueryparam value="#ARGUMENTS.equipment_name#" cfsqltype="cf_sql_varchar">
    AND customer_name= <cfqueryparam value="#ARGUMENTS.customer_name#" cfsqltype="cf_sql_varchar">
    </cfquery>

    <cfreturn get_equipment>

但是我的 CFC 抛出错误：

The parameter customer_name to function getDetails is required but was not passed in.

如何成功传递这两个参数和 return 我的查询结果？

您在 Ajax 函数的数据属性中没有为 customer_name 关闭 "。您的 Ajax 函数应该看起来像这样

$.ajax({
 type:"POST",
 url:"cfcs/get_equipment_details.cfc?method=getDetails",
 data: { equipment_name: "#equipment_name#", customer_name: "#customer_name#"},
        cache:false,
        success: function(msg) {
         $("##customer_name#id#").val(msg); 
    }
 });

现在您的 cfc 函数出现了一些问题。您正在 returning 一个不存在且与您的函数名称相同的变量。如果你这样做，它会起作用

<cffunction name="getDetails" access="remote" output="false" returnformat="JSON">
    <cfargument name="equipment_name" type="any" required="true">
    <cfargument name="customer_name" type="any" required="true">

    <!--- Get list of all equipment --->    
    <cfquery name="get_equipment" datasource="#datasource#">
    select *
    from equipment_maintenance
    where equipment_name= <cfqueryparam value="#ARGUMENTS.equipment_name#" cfsqltype="cf_sql_varchar">
    AND customer_name= <cfqueryparam value="#ARGUMENTS.customer_name#" cfsqltype="cf_sql_varchar">
    </cfquery>

    <cfreturn get_equipment.customer_Name>
</cffunction>

如果您希望整个查询对象在您 ajax 响应时成为 return，则在 ajax 成功时解析 JSON 并进一步处理它
