使用 async await 取代 promise

        async afterSelect(item) {
            var that = this;

            //更改状态
            var result = await axios.post('/OrdersProduction/LoadTotalQty', JSON.stringify({ orderId: item.id }));
            if (result && result.data && result.data.Success) {
                if (parseInt(item.plan_qty) - parseInt(result.data.Data) <= 0) {
                    that.$message.error("此订单已无剩余生产数！");
                    return;
                } else {
                    that.maxqty = parseInt(item.plan_qty) - parseInt(result.data.Data);
                    that.order = Object.assign(item);
                    //获取配方版本列表
                    var recipeResult = await axios.post('/MixOilRecipe/GetModels', { condition: " oil_code_id = '" + item.item_id + "'" });
                    if (recipeResult && recipeResult.data && recipeResult.data.Success) {
                        that.recipeOptions = recipeResult.data.Data;
                    }
                }
            }
        },
