            });
        }

錯(cuò)誤提示是 carts.forEach is not function

想得出循環(huán)累加單價(jià) * 數(shù)量。。。謝謝

goods_list是對(duì)象屬性，應(yīng)該放在對(duì)象里（carts應(yīng)該是對(duì)象）表達(dá)式才正確。

夢(mèng)一場(chǎng)

首先，你的最外層應(yīng)該是花括號(hào)

calcTotalmoney: function () {
            var self = this;
            this.totalMoney= 0;
            var num =0.00;
            for (var index in this.carts) {
                this.carts[index].forEach(function (g) {
                   num += parseFloat(g.price * g.quantity);
                });
            }
            return num;
        },
