我们在操作数组时，加入数组中是以对象的形式存在，例如：

那么我们会涉及到去重复，去掉为0的数组中的对象，js代码如下：

function getItemList(gid, totalMoney, addNum) {                var data = {                    "SI_GID": gid,                    "TotalMoney": totalMoney,                    "TotalNum": addNum                };                if (addNum > 0) {                    if (hotelList.length > 0) {                        var Ishave = false;                        var flag = 0;                        for (var i = 0; i < hotelList.length; i++) {                            if (hotelList[i]["SI_GID"] == gid) {                                Ishave = true;                                flag = i;                                if (i == 0) {                                    flag = -1;                                }                                break;                            }                        }                        if (!Ishave) {                            hotelList.push(data);                        }                        if (flag > 0) {                            hotelList[flag]["TotalMoney"] = totalMoney;                            hotelList[flag]["TotalNum"] = addNum;                        }                        if (flag == -1) {                            hotelList[0]["TotalMoney"] = totalMoney;                            hotelList[0]["TotalNum"] = addNum;                        }                    }                    else {                        hotelList.push(data);                    }                }                else {                    for (var i = 0; i < hotelList.length; i++) {                        if (hotelList[i]["SI_GID"] == gid) {                            hotelList.splice(i, 1);                        }                    }                }                console.log(hotelList);            }
