前端 传表格多条数据 给后台接收 （HTML前端表格多条数据JSON封装后；异步提交到后台处理)

1.多条数据采用checkBox 携带

 //封装数据的对象
     var PayObj =  
        {  
          O_NBR:"",    
          P_NBR:"",  
          O_AMOUNT:""  ,
          P_DT:"",
          P_HL_ZH:"",
          P_PAY_TYP:"",
          P_POS:"",
          P_U_ZH:"",
          P_U_HM:"",
          P_ATTR_IMGS:"",
          P_RECEIPT_NBR:""
        }

	var a = JSON.parse("{\"title\":\"\",\"data\":[]}");

2. 遍历表格封装数据：（表格的每一行是一个JSON对象；多行就是一个JSON数组，JSON数组在弄成一个对象）

function getChecked() {
		$('input[name="check[]"]:checked').each(function() {
			var PayObj = new Object();
			roleids += $(this).val() + ",";
			requestTransNo += $(this).val()  + ",";
			cardNo += $(this).attr('cardNo') + ",";
			cardUser += $(this).attr('cardUser') + ",";
			refundAmt += $(this).attr('refundAmt') + ",";
			tranNo += $(this).attr('tranNo') + ",";
			dealDate += $(this).attr('dealDate') + ",";
			orderId += $(this).val()  + ",";

			PayObj.requestTransNo = $(this).val();
			PayObj.cardNo = $(this).attr('cardNo');
			PayObj.cardUser =  $(this).attr('cardUser');
			PayObj.dealDate = $(this).attr('dealDate');
			PayObj.orderId = $(this).val();
			PayObj.tranNo = $(this).attr('tranNo');
			PayObj.refundAmt = $(this).attr('refundAmt');
			PayObj.refundReason = document.getElementById('refundReason').value;
			alert(document.getElementById('refundReason').value);
			a.data.push(PayObj);//向JSON数组添加JSON对象的方法；很关键
		});
}

3

  ///格式化数据
             var obj=JSON.stringify(a);//这一行很关键

4. 异步提交数据

$.ajax({
			type: "post",
			url : "${ctx}/refund/transferPaymentReback/ajaxRefundTransferPaymentReback.do",
			dataType: "json",
			cache: true,
			data:{'param':obj},
			success: function (data) {
				showAlertMsg(data.flag.errorMsg, {
					closeFunction: function () {
						if (data.flag.success == true) {
							window.location.href="${ctx}/member/relation/bankOfHuaXiaManager.do"
						}
					}
				});
			},
			error: function () {
				alertMsg(null, false, null, null, "调用接口失败，请稍后重试!");
			}
		});

5.后台解析接收数据

String param = request.getParameter("param");
        JSONObject json=JSONObject.fromObject(param);
        List<Map<String,String>> payList=json.getJSONArray("data");
