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
