Ajax调用Conrtoller返回数据

前端ajax

function doRefund()
{

  

$.ajax({
            type: "POST",
            catch: false,
            url: "@Url.Action("AliBarPay", "Alipay")",
            data: {
            strTradeNo: $("input[name='strTradeNo']").val(),
            strAuthcode: $("input[name='strAuthcode']").val(),
            strTotalAmount: $("input[name='strTotalAmount']").val()
            },
            dataType:'json',//返回数据类型为json类型
            success: function (json) {
                if (json.result) {
                    alert(json.msg)
                } else {
                    alert(json.msg);
                }
        },
        error: function (json) {
            alert(json.msg);
        }

    });

}

  后端controller中代码:

public ActionResult AliBarPay(string strTradeNo, string strAuthcode, string strTotalAmount)
        {
            AlipayTradePayContentBuilder builder = BuildPayContent(strTradeNo, strAuthcode, strTotalAmount);
            string out_trade_no = builder.out_trade_no;

            AlipayF2FPayResult payResult = serviceClient.tradePay(builder);

            bool bResult = false;
            switch (payResult.Status)
            {
                case ResultEnum.SUCCESS:
                    DoSuccessProcess(payResult);
                    bResult = true;
                    strResult = "支付成功!";
                    break;
                case ResultEnum.FAILED:
                    DoFailedProcess(payResult);
                    break;
                case ResultEnum.UNKNOWN:
                    strResult = "网络异常,请检查网络配置后,更换外部订单号重试";
                    break;
            }
            var vJson = new { result = bResult, msg = strResult };
            return Json(vJson);//返回json类型
        }

 

 $.ajax({
            type: "POST",
            url: "/Alipay/AlipayRefund",
            data: {
                strTradeNo: $("input[name='strTradeNo3']").val(),
                strProductId: $("input[name='strProductId']").val(),
                strRefoundAmount: $("input[name='strRefundAmount']").val(),
            },
            dataType: "text",//返回类型为string的
            success: function (result) {
                if (result == "" || result == null)
                {
                    alert("无返回值");
                    return;
                }
                $("#refundDetail").html(result);
                alert(result);
            }
        });

  后端controller:

 public ActionResult AlipayRefund(string strTradeNo,string strProductId,string strRefoundAmount)
        {
            AlipayTradeRefundContentBuilder builder = BuildRefundContent(strTradeNo, strProductId, strRefoundAmount);


            AlipayF2FRefundResult refundResult = serviceClient.tradeRefund(builder);

            switch (refundResult.Status)
            {
                case ResultEnum.SUCCESS:
                    strResult = DoRefundSuccessProcess(refundResult);
                    break;
                case ResultEnum.FAILED:
                    strResult = DoRefundFailedProcess(refundResult);
                    break;
                case ResultEnum.UNKNOWN:
                    if (refundResult.response == null)
                    {
                        strResult = "配置或网络异常,请检查";
                    }
                    else
                    {
                        strResult = "系统异常,请走人工退款流程";
                    }
                    break;
            }

            return Content(strResult);//返回string类型

        }

其中必须注意的是,如果是button来调用ajax,必须指定button的type='button',不然在ajax中不会返回值:

<div>
    <span>支付宝退费</span>
    <form>
        <span>商户订单号:</span><input type="text" name="strTradeNo3" />
        <span>支付宝订单号:</span><input type="text" name="strProductId" />
        <span>总金额金额:</span><input type="text" name="strRefundAmount" />
        <button id="doSubmit4" type="button"  onclick="doRefund()">退费提交</button>//type='button' 必须写,不然在方法中执行没得返回值,但chrom中调试可以显示,不调试时,就是显示不出来!!!
    </form>
    <span id="refundDetail"></span>
</div>
