修复购物车数量不同步的BUG

[ 本帖最后由 amwso 于 2020-6-21 22:34 编辑 ]\n\nsetCartNum(cartId, cartNum, successCallback) {

var that = this;

changeCartNum(cartId, cartNum).then(res => {

successCallback && successCallback(res.data);

//二开 修复购物车bug

var numSum = 0,i = 0;

for (i = 0; i <= that.data.cartList.valid.length-1; i++) {

if (that.data.cartList.valid.id == cartId) numSum += cartNum;

else numSum += that.data.cartList.valid.cart_num;

}

that.setData({ cartCount: numSum });

});

order_addcard页面下的js 里面搜setCartNum整个函数替换就可以解决问题[/hide]
