开发准备
上一节我们已经实现了优惠券的选择并且成功的把券后的价格也展示给用户不能使用的优惠券我们也用友好的方式告知用户这一节我们来实现优惠券内容的下一步优惠券内容结合订单进行结算提交
功能分析
因为我们之前的订单列表是订单相关商品相关是分开的所以在这里我们同样要把优惠券的内容分开只存储id进去后续再查询出对应的券金额我们首先就是要修改订单表然后在券选择的同时拿到优惠券的相关内容提交订单时把优惠券内容一起提交方便我们后续的订单详情内查询券后价
代码实现
首先修改orderlist的表内容
{CloudDBZoneName: default,objectTypeName: order_list,fields: [{fieldName: id, fieldType: Integer, notNull: true, belongPrimaryKey: true},{fieldName: user_id, fieldType: Integer, notNull: true, defaultValue: 0},{fieldName: order_code, fieldType: String},{fieldName: order_status, fieldType: Integer},{fieldName: order_product_id, fieldType: String},{fieldName: coupon_id, fieldType: Integer},{fieldName: address, fieldType: String},{fieldName: nickname, fieldType: String},{fieldName: phone, fieldType: String},{fieldName: order_remark, fieldType: String},{fieldName: pay_type, fieldType: String},{fieldName: order_create_time, fieldType: String},{fieldName: order_pay_time, fieldType: String},{fieldName: order_delivery_time, fieldType: String},{fieldName: order_over_time, fieldType: String}],indexes: [{indexName: field1Index, indexList: [{fieldName:id,sortType:ASC}]}],permissions: [{role: World, rights: [Read, Upsert, Delete]},{role: Authenticated, rights: [Read, Upsert, Delete]},{role: Creator, rights: [Read, Upsert, Delete]},{role: Administrator, rights: [Read, Upsert, Delete]}]
}然后我们在选择券的时候拿到券的id这里我们用回调的方式实现
//自定义弹窗页面onItemSelected: (coupon_id:number) void () {};//结算页State coupon_id:number0couponController: CustomDialogController| null new CustomDialogController({builder: CouponCheckDialog({couponPrice:this.couponPrice,price:this.price(),onItemSelected:(coupon_id:number){this.coupon_idcoupon_id}}),alignment: DialogAlignment.Bottom,customStyle:true});
结算订单时合并信息提交 Text(提交订单).fontColor(Color.White).padding(10).borderRadius(10).backgroundColor(#d81e06).fontSize(14).onClick(async (){if (this.addressInfo!null) {let databaseZone cloudDatabase.zone(default);try {for (let i 0; i this.productList.length; i) {let productPush new order_product_list();productPush.idthis.codeIdiproductPush.order_product_idthis.codeIdproductPush.imgthis.productList[i].productImgAddressproductPush.pricethis.productList[i].productPriceproductPush.namethis.productList[i].productNameproductPush.originalPricethis.productList[i].productOriginalPriceproductPush.specthis.productList[i].productSpecNameproductPush.buyAmountthis.productList[i].buyAmountlet num await databaseZone.upsert(productPush);hilog.info(0x0000, testTag, Succeeded in upserting data, result: ${num});}}catch (e) {hilog.info(0x0000, testTag, Succeeded in upserting data, result: ${e});}let orderPush new order_list();orderPush.idMath.floor(Math.random() * 1000000)orderPush.user_idthis.user!.user_idorderPush.order_product_idString(this.codeId)orderPush.order_codethis.generateOrderNo(10)orderPush.order_status0if (this.remark!) {orderPush.order_remarkthis.remark}orderPush.coupon_idthis.coupon_idorderPush.addressthis.addressInfo.addressorderPush.nicknamethis.addressInfo.nikeNameorderPush.phonethis.addressInfo.phoneorderPush.order_create_timethis.formatCurrentDate()orderPush.order_pay_timethis.formatCurrentDate()let num await databaseZone.upsert(orderPush);hilog.info(0x0000, testTag, Succeeded in upserting data, result: ${num});if (num0) {for (let i 0; i this.productList.length; i) {if (this.productList[i].isNeedPay) {let item new cart_product_list();item.idthis.productList[i].idlet listData await databaseZone.delete(item);hilog.info(0x0000, testTag, Succeeded in upserting data, result: ${listData});}}let eventData: emitter.EventData {data: {}};let innerEvent: emitter.InnerEvent {eventId: 1012,priority: emitter.EventPriority.HIGH};emitter.emit(innerEvent, eventData);router.replaceUrl({url:pages/view/OrderSuccessPage,params:orderPush})}} else {showToast(请先选择地址)}})到这里我们就实现了结算订单跟优惠券的关联
