ajax的data传参的两种方式

1.

/** * 订单取消 * @return {Boolean} 处理是否成功 */function orderCancel(orderId, commant){var flag = false;$.ajax({    type: "POST",    url: "../order/orderCancel.action", //orderModifyStatus    data: {"orderId":orderId,"commant":commant},    dataType:"json",    async:false,    cache:false,    success: function(data){    var member = eval("("+data+")"); //包数据解析为json 格式                                                                  if(member.success=="true"){        flag = true;        }else if(member.success=="false") {        alert(member.info);        }},error: function(json){alert("订单取消异常，请刷新后重试...");}    });    hidediv();    return flag;}

 

2.

data: "orderId=" + orderId + "&commant=" + commant
