三、方法代码
watch(itemList, () {console.log(itemList.value, itemList)let totalLossoverRetail 0let totalLossoverPurchase 0itemList.value.forEach(item {totalLossoverRetail Number(totalLossoverRetail) Number(item.totalLossoverRetail);totalLossoverPurchase Number(totalLossoverPurchase) Number(item.totalLossoverPurchase);})sumDescription.value 成本损溢金额 totalLossoverPurchase 零售损溢金额 totalLossoverRetail
}, {deep: true});
其中开启深度监听
四、效果
