2020-10-04 bought.html没有任何订单展示出来啊

sparksun007

关于实践项目-天猫整站Springboot-我的订单页的提问

调试服务端返回数据正常，前端ajax接收到的vue.orders数组返回正常结果。前端boughtPage.html用的老师的代码，但就是展示不出来站长写的<table v-for = "o in orders" class="orderListItemTable" :orderStatus="o.status" :oid="o.id"> 到了chrome和Firefox浏览器就变成了这样：<table :oid="o.id" :orderStatus="o.status" class="orderListItemTable" v-for="o in orders"> 不知道是不是这个顺序问题，反正chrome错误提示是这样：vue.min.js:6 TypeError: Cannot read property 'id' of null 搞不懂了啊。。。

                    var uri = "foreDeleteOrder?oid="+deleteOrderId;

@俗人。。。。好奇怪哦，我的 chrome 就是好的。你是什么版本呢

答案时间：2020-02-24

哈哈哈哈哈，站长，不是浏览器的问题，我这用的Chrome，也是这样，然后去前面的天猫前端项目找了下这个表头的样式讲解部分，然后挨个比较，觉得估计是站长对于这个div.orderTypeLastOne的css样式部分漏了点什么，然后回到项目，打开前台fore-->style.css文件，查找发现，果然。。。。。。（在1669行，漏写了个height属性，而且站长的前端项目里设置的35px产生的效果仔细看还是有点不平整。。。。。哈哈哈，34px就很完美~~）

你确定用过步骤1了吗？我刚才用了步骤1是可以的啊。并且在 listByUserWithoutDelete 方法里有给订单填充订单项的代码哦 orderItemService.fill(orders);

public List<Order> listByUserWithoutDelete(User user) {
		List<Order> orders = listByUserAndNotDeleted(user);
		orderItemService.fill(orders);
		return orders;
	}
